The ＂chain＂ on the data is the ＂health account＂ of the battery, and the new energy battery realizes the green cycle.

　　CCTV News:In recent years, China’s new energy vehicle market has experienced explosive growth, and a round of "retirement tide" of new energy batteries is also coming. The battery contains a variety of heavy metals, which will cause environmental harm if it is not handled properly. While the new energy automobile industry is booming, where should the retired batteries go?

　　In a battery recycling plant in Guangdong, the reporter saw that the batteries retired from new energy vehicles were piled up in the whole factory.

　　Lin Xiaojie told reporters that in order to deal with the surge of retired batteries, the company built two new factories in Jiangmen and Jiangsu in 2023, and opened 10 new production lines. After the retired batteries enter the factory, they will go through the processes of screening, crushing and smelting. Valuable metals such as nickel, cobalt and manganese are extracted and resold. However, if this process is not handled properly, it will cause pollution to the environment.

　　According to statistics, China has entered a period of large-scale decommissioning of power batteries. In 2023, China’s decommissioned power batteries will reach 590,000 tons. Since 2028, the decommissioning of power batteries in China will exceed 2.6 million tons per year. What should I do with the surge in retired batteries? The reporter saw various solutions in the investigation.

　　According to the national standard for new energy vehicles, the remaining 80% capacity of the power battery can be retired. The decreased battery capacity will reduce the cruising range and affect the user’s experience. However, retired batteries can still be used in energy storage, electric bicycles and other scenes with low requirements on battery performance to achieve "step utilization".

　　The "chain" on the data is the "health account" of the battery book.

　　Although "step-by-step utilization" can prolong the service life of power batteries, it is not easy for recycling enterprises to practice, mainly because the cost of knowing the loss degree of retired batteries is very high. The reporter found in the investigation that the application of a new technology is bringing changes to the industry.

　　In front of this big screen, the health data of more than 30 thousand power batteries are flashing in real time. Don’t underestimate these data. Liao Zhicheng, the head of the battery operation company, told reporters that they can make some batteries sell for three times more when they are recycled.

　　In the past, if you want to reuse the retired batteries, the recycler can only disassemble the battery pack, test the health of each battery cell, pick out the appropriate ones and assemble them into new battery packs. And more recycling enterprises that lack the corresponding technology and manpower can only dismantle and crush the retired batteries as waste products and sell the heavy metals in the batteries directly.

　　The chip in Liao Zhicheng’s hand is like a "healthy housekeeper" on the battery. It not only "accounts" the use of the battery at all times, but also uploads the data to the blockchain platform in real time so that they cannot be tampered with. In this way, the recycler can know all the "health data" of the battery without disassembling them one by one. The reporter learned that battery packs with a high degree of "health" can be sold to 300 yuan at the time of recycling, which is three times that of the past.

　　At present, China has built the world’s largest new energy equipment blockchain platform, with more than 8 million new energy equipment on the chain. With the use of street lamps, toys and other scenes that require less battery capacity to join the cycle, it is possible to use new energy batteries more times.

　　Green cycle of new energy batteries from production to recycling.

　　After retirement, the service life of new energy batteries will become longer, but they will eventually be dismantled and recycled. How to make the new energy battery form a green cycle of energy saving and environmental protection from production to recycling?

　　China’s lithium resources account for only 7% of the world’s total, but China’s production and sales of electric vehicles account for 60% of the world’s total. Therefore, it is of great significance to extract lithium, cobalt, nickel and other metals from batteries and recycle them into new batteries.

　　The reporter learned in the investigation that at present, more than half of the retired batteries are handled by enterprises that do not have the qualification to handle them. There are some problems in dismantling and recycling, such as high energy consumption, low metal recovery rate and poor environmental protection. In view of the present situation, the Ministry of Industry and Information Technology announced four batches of white list enterprises for power battery recycling, and actively guided the regularization of power battery recycling.

　　Experts told reporters that to form a stable, green and sustainable recycling system for power batteries, unified national standards, industry standards, recycling standards and recycling channels are needed. In recent years, China has successively issued national standards such as power battery disassembly specifications and residual energy detection, so as to promote the national unified coding of power batteries. The relevant departments said that they are speeding up the formulation of the Management Measures for the Recycling of Power Batteries for New Energy Vehicles to further improve the standard system of power batteries.

Staff： Accurate Music Language

　　A special music performance was held in Montpellier, a city in the south of France. Eighteen birds played a wonderful movement on a Gibson electric guitar.

　　With the piano entering more and more families, the staff has changed from "familiar face" to "explosive red" among the general public. Because in piano teaching, the notation of staff is widely used all over the world, and only the staff can fully express the music score.

　　Notation is to music what words are to language.

　　The earliest information of human music can only be preserved from generation to generation through oral instruction. Before the modern high-tech sound carrier appeared, there was only one notation for recording and storing music. At present, the most well-known staff faithfully "writes" the composer’s creative intentions and achievements, which can be called a spectacle created by human music civilization and a microcosm of the emergence and development of music language.

　　1. The music recorded on plants opens the notation.

　　The earliest origin of staff can be traced back to ancient Greece. Music occupies a very important position in the field of knowledge in ancient Greece. The ancient Greeks used two notations, both of which used letters or similar letters as symbols. One was used to record the melody of vocal music, and the other was used to record the melody of instrumental music. Vocal music notation originated in Ionian at the end of the 5th century BC, and instrumental music notation may be earlier. It is said that the music written in the Vienna National Library on the plant products called Pa Pirus is the oldest music in the world, with a history of two thousand years.

　　Some studies also show that a city discovered in 1918, 100 miles southwest of Cairo — — In an ancient ruins in Oxilinkus, researchers found a written record of music — — A hymn fragment written on papyrus. In those days when music was usually spread by word of mouth, even the private remains scrawled on papyrus were extremely rare. This is also the only music record that survived in the first 400 years of Christianity. Above this hymn, the pitch and sound value are recorded by some alphabetic arrangement or simple auxiliary line symbols, which is also a typical feature of the earliest music score format. It has eight different notes, spanning an octave, these letters arranged in a straight line, each note corresponds to a scale, and the scale combination of long and short squares; The horizontal strokes and individual dots on the notes indicate which words should be emphasized when singing.

　　In addition, a scholar from the University of California, Berkeley, published an article in 1985, demonstrating that the earliest musical notation was found on the cuneiform tablets originating from the two river basins.

　　As the predecessor of staff notation — — Newham notation appeared in the 8th century AD. The word "Neum" comes from Greek, which means "symbol" and is a way to express music in the form of drawing. Since the 8th century, in order to prevent those uncommon hymns from being forgotten because of too long interval, monks who copied hymns added some symbols similar to language stress or punctuation at the top of the lyrics, indicating the up-and-down trend of hymns concisely. This symbol is called "Neum Spectrum".

　　In the early days, Newham notation was limited to indicating the direction of hymn tunes, and could not indicate the pitch position and note length. Later, someone creatively used a straight line to mark Newham spectrum to the top and bottom of this straight line, and defined this straight line as F, so the ancestor of staff appeared — — A line spectrum.

　　In the middle of the 9th century, a complete hymn melody copied with Newm symbols appeared. In the development of notation, some places began to arrange the upper and lower spatial distances between Neum symbols according to the size of intervals. Moreover, Newham notation indicating the pitch and interval structure of melody has gradually formed, and some symbols can indicate a single note or a group of notes, which helps people to record music melody completely. Later, this Newham spectrum gradually developed into two-line spectrum and three-line spectrum.

　　It took nearly four centuries to change from color to black and white.

　　Different from today’s black-and-white world, the staff was colorful in the process of reproduction.

　　In the 11th century, Guido D ‘Alezzo, a musician in arezzo, Italy, added Newham spectral lines to four lines, and specified the pitch as D, F, A and C, and the range was about eight degrees. Different pitches were expressed by clef or color, and the red line represented F sound, and the yellow line or green line represented C sound, which made the pitch more accurate. This kind of music score was called "four-line score", and they later became high notes in the staff. Since then, due to the need of playing, Newham’s spectrum has appeared six-line spectrum, seven-line spectrum and even eleven-line spectrum. To commemorate the invention and birth of the staff, people called Guido D ‘Alezo "the father of the staff".

　　Then, how does the staff come from "stepping on colorful auspicious clouds" return to the black and white world?

　　More and more composers are involved in the exploration of more accurate music notation. By the 13th century, the four-line score used all black lines, only a Latin letter was written at the front of the line to indicate the absolute pitch of this notation. This method gradually became popular in Europe at that time. But unfortunately, it still can’t show a clear rhythm. Especially the multi-part melody is becoming more and more complex, and people urgently need to find a way to accurately describe the length of each sound. At this time, a monk named Frank in Cologne, Germany, pioneered the different lengths of "black notes" in his book The Art of Theorem Songs. This notation, which strictly specifies the length of notes, rests and marks, is a supplement and enrichment to Newham’s spectrum and can be called a landmark improvement in the development of line spectrum.

　　In the 15th century, the trend of black notes receded, and the types of notes increased, and hollow notes appeared to represent the sound value, which is also commonly known as "white notes". With the development of line spectrum in this period, the position of pitch and the length of sound can be basically recorded, and the Fu Tou has also become a circle.

　　In order to change the situation that the spectral lines of musical scores are too many and complicated, European countries later unified Newham spectrum into five lines, and the notes that are too high or too low were expressed by adding lines, which made the recording of pitch more perfect. Since the 17th century, the staff developed on the basis of Newham’s spectrum and quantitative notation tends to be perfect, gradually finalized and has been used ever since.

　　After centuries of "tempering", the staff has gradually reached unprecedented accuracy. According to this, composers can mark the changes of volume, speed and timbre more carefully, which can be said to be "presented in detail"

　　When water is full, it overflows. Too precise music "language" was later considered by some people as a "double-edged sword". Although it can convey the composer’s creative intention in detail, it squeezes the space for the performer to improvise, which makes the musician shout "not enough". As a result, the direction of notation has changed again, and the final interpretation right of music has been returned to the performers. The performers no longer stick to "accurate presentation" but boldly release their individuality, which makes each performance unique.

　　At this point, music notation has gone through thousands of years of development, from being a summary of memos at first, to helping players repeat performances accurately, and then returning to the original point after a big circle.

　　3. The first "cross-border" album recording traditional Chinese opera comes from Mei Lanfang.

　　In the history of music development in China for thousands of years, there have been many ways of notation, such as subtractive notation, metrical notation, Lv Zi notation, etc. Up to now, except for Gongchi notation, there are a few old folk artists who are using it, and other notation methods are forgotten because they are too cumbersome.

　　Accompanied by drums, ancient people sat together, playing games and cheering for fun — — In this way, the embryonic form of early China’s music score was derived from entertainment. Drum music in the Book of Rites Throwing Pots is the oldest ancient music score in China, which appeared in the Zhou Dynasty and has a history of more than 3,000 years. There are some comma symbols in the score, which are arranged vertically in turn, as well as the words "drum", "semi-drum" and "Xue drum". Experts speculate that these are the terms related to performance, and professionals can also simulate the powerful beat from them.

　　In Guan Zi Di Yuan Pian written in the Spring and Autumn Period, a mathematical method for calculating the chord length ratio of each tone in pentatonic scale is recorded, which is called "three-point gain and loss method" in history, and the names of pentatonic scale "Gong, Shang, Jiao, Zheng and Yu" in China are completely described. As to where these five names came from, there are different opinions. Some say that they correspond to the stars, some say that they are derived from five animals, and some say that they are totems of ancient clans. All kinds of opinions paint a mysterious color on music and express the different musical concepts of China ancestors. Up to today, little is known about "Gong Shang Shu", but the five tones of "Gong Shang, Jiao, Zheng and Yu" are quite well-known. For example, in the theme song "Long Wen" of Happy Dictionary of CCTV, there is a lyric that "Gong Shang Jiao Zheng Yu, Qin Qi calligraphy and painting sing, peacocks fly southeast, and weaver girls will be cowherd &hellip. …” This song has been sung by stars many times, and it has also been on the Spring Festival Evening in 2010, which became a hit overnight.

　　Compared with the western staff and notation, China’s classical music score does not form the accurate quantification of pitch and rhythm and the transcoding of digital symbols, but only the outline record of the basic pitch and rhythm of traditional music or aria, which gives the performers and singers much more freedom and uncertainty in creation than the western music score, so it is also called "frame score".

　　The staff was introduced into China in the mid-17th century. There is a written record in Xieyun Duqu, a sequel to Lv Zheng Yi written by Emperor Kangxi in 1713, which published in detail the knowledge of western music theory such as staff, scales, roll names, etc. Although the staff at that time was only in its primary form and its symbols were very different from today’s, it was spread through this printed book.

　　The staff, which has just entered the country, is only used to record and spread the classic songs and hymns that praise God sung in the Catholic church. It was not until the end of the 19th century that it was gradually accepted and used by Chinese people. In 1930, Mei Lanfang’s operas were recorded by musician Liu Tianhua for the first time, and Mei Lanfang’s Songs was published, which is also the first "cross-border" album in China to record traditional opera music with staff.

　　4. The notation has been carried forward in China.

　　There are two kinds of musical notation: numbers and letters. The most common musical notation is numbers, and its embryonic form first appeared in Europe in the 16th century. At that time, a French Catholic priest named Suaiti wrote music songs with seven sounds, namely 1, 2, 3, 4, 5, 6 and 7, and compiled a pamphlet "New Methods of Learning plainsong and Music". In the mid-18th century, Rousseau, a famous French thinker who was famous for his book Confessions, also read the Proposal for New Musical Symbols to the Paris Academy of Sciences, and mentioned the "digital notation". Later, a group of social elites improved and popularized it, and finally formed the notation, which was also called "Galpa-Xie notation" in the west.

　　This notation was introduced to Japan in 1882. In 1903, Zeng Zhimao, one of the earliest music theorists in the history of modern music in China, published the article "The General Idea of Music Theory" in a chinese magazine published in Tokyo, introducing the knowledge of western music theory, and published six songs such as "Training" and "Spring outing" in the form of comparison between notation and staff, which is the earliest record of Chinese people using notation at present.

　　Shen Xingong, a modern music educator, was also one of the earliest disseminators of musical notation. His School Singing Collection was the first collection of musical notation written and published by China. Since then, notation has gradually spread to schools all over the country. In the 1930s, the mass singing movement of resisting Japan and saving the nation was widely carried out. At that time, famous pop songs, such as March of the Volunteers of Nie Er and The Yellow River Cantata of Xian Xinghai, were written by notation. With the widespread singing of these songs, notation gradually became popular among ordinary people in China.

　　The notation of musical notation is the closest to the popular Gong-Chi notation in China, and it is simpler and more accurate to record the height of notes by musical notation. Therefore, musical notation has developed rapidly in China, and some experts even think that China is the country that absorbs and uses musical notation the best and develops it the most in the world. Especially in the field of folk music, notation fits the characteristics of Chinese folk music, because notation records only the general framework of melody, and more needs face-to-face communication between teachers and students; On the playing method of musical instruments, Chinese folk music has many special expressive force symbols, and the use of notation is clear and clear. If staff is used, it will become complicated. These are the important reasons why notation is highly praised by Chinese folk music.

　　Of course, this is just a matter of habit. With the blending of modern Chinese and western cultures, more and more folk music also adopts the notation of line notation. In fact, in the field of folk music, there are still many places where staff can be used, and that is the ensemble moment. When all kinds of musical instruments play the same piece of music according to different parts, the powerful function of the staff is revealed, which is unmatched by the notation.

　　No one can replace the staff or the simple staff.

　　Jacky Cheung, a Hong Kong singer who is known as the "God of Songs" in the Chinese music scene, once bluntly said that he did not know the staff, but only knew the simple music. Nowadays, at the scene of some music variety shows, some judges are repeatedly criticized by netizens because they can’t understand the staff. So, is the staff really more "advanced" than the notation?

　　Experts pointed out that in the history of music development, people have created various different notations according to their own needs, and different musical instruments, regions and traditional cultures may produce very different notations. Such as guqin, using guqin notation; Traditional Chinese opera uses the notation of gongs and drums. There is also the traditional notation of Gongchi notation in our country, but now there are the most familiar notation, staff notation and so on. We can’t simply say which notation is the best, but which method is relatively scientific. Through accurate notes and various dynamic symbols and emoticons, we can try our best to return the expression intention of the original composer.

　　Objectively speaking, staff notation and simple notation both play an important role in the field of Chinese music culture. They complement each other and have irreplaceable functions, but their users are different.

　　Notation is simple and clear. Even now, many popular music still uses notation. Compared with other notation, staff has irreplaceable advantages. It records the level of music by the position of the Fu Tou of the note on five parallel horizontal lines, and indicates the length of the note by the different shapes of the note, which can not only visually indicate the pitch of the musical sound, but also accommodate the music information in a large amount, especially in recording and writing large-scale ensemble music with wide range, numerous parts and frequent tone sandhi. Therefore, since the 18th century, the staff has become the main position of music notation, and it has been widely used in the field of professional music in the world today.

　　Nowadays, pianos have entered more and more families. In piano teaching, the notation of staff is widely used all over the world, and only the staff can fully express the music score. At the same time, the performance and singing of various music groups, the teaching of music colleges and the learning of piano children all played a very important role in the spread of staff.

　　Do you know

　　Can’t clap between concerts?

　　At the end of the year, many concerts were held together. Watching a concert is different from watching a movie. There are many unwritten rules, such as not applauding between the movements of a symphony, waiting for a complete track to enter the venue when you are late, and so on. Where did these rules come from that the enthusiastic audience couldn’t understand?

　　There was a controversy about whether there was applause between movements. Before the end of 19th century, clapping between movements was "not a thing". Mozart gets excited when he hears the applause of the audience when he plays. Once, in a letter to his father, he mentioned, "There is a passage in the middle of Allegro in the first movement, which I know the audience will like very much … … Sure enough, the audience were all in ecstasy and the applause was very warm. I expected this long ago. When I wrote this paragraph, I knew it would be very effective. At the end of the movement, this piece of music appeared again, and sure enough, the audience shouted again and asked to repeat it … …” Repeated applause made Mozart very happy. After the symphony, he even went to the Royal Garden to buy ice cream to reward himself.

　　Until the end of 19th century, there were professional cheering people in European opera houses. The function of these "masters" was to cheer in some boring opera performances. Perhaps this move is not flattering. From the end of the 19th century to the beginning of the 20th century, most audiences accepted the etiquette agreement of not clapping between movements. Moreover, it has been recognized by some composers. For example, in Mourning for the Dead, Mahler even pointed out that there should be no applause in the middle of the movement.

　　In addition, there is an important etiquette for listening to the concert, that is, you can’t be late. If you are late for some reason, you must wait for the guidance of the theater staff and wait for a complete track (not a movement) before you can enter. In fact, being late was not condemned as early as the mid-19th century, because early concerts belonged to small gatherings in aristocratic circles, and being late and leaving early was commonplace. By the end of the 19th century, after Mahler was in charge of vienna state opera, he resolutely implemented the rule that late spectators were not allowed to enter the venue, even if the royal family members were late, which became a etiquette until now.

　　There is such a saying

　　The New Year concert originated from the old Strauss.

　　The New Year is a common festival for people all over the world. There are many ways for people to celebrate the New Year, but holding a high-level concert is a program in major cities all over the world, welcoming the beginning of the new year with relaxed and wonderful music.

　　The tradition of holding concerts in the New Year originated in Vienna. On December 31st, 1847, Johann Strauss I, the founder of the Strauss music family, held an open-air concert in the suburb of Vienna. The repertoire included symphonies, waltzes and polkas, which were warmly welcomed by the audience, so that the concert didn’t end until dawn the next day. This is the origin of the Vienna New Year Concert.

　　Today, the annual New Year Concert held in Vienna Golden Hall is still the most eye-catching annual music event in the world. Most TV stations and radio stations around the world broadcast live, with tens of millions of listeners. Inspired by this tradition, many countries or cities in the world have also held New Year concerts to celebrate the arrival of the New Year.

　　Austrian composer’s manuscript sells at sky-high price

　　The original manuscript of the score of Austrian composer gustav mahler’s Second Symphony was sold for 4.5 million pounds at an auction held in London, England recently. The 232-page score set a new record for the auction of the score.

　　The music seller is the family of Gilbert Kaplan, an American economist and businessman who died two years ago. There is an amazing story behind the score. According to the Daily Mail, Kaplan was fascinated by this symphony, also known as Resurrection, after listening to it at Carnegie Hall in new york in 1965. Never having studied conducting, he is determined to conduct the best orchestra in the world to perform this piece of music one day and put his determination into action.

　　Kaplan once described the feeling of listening to Resurrection as follows: "When I entered the concert hall, I was alone, but when I came out, I felt like I was struck by lightning." In the next 17 years, Kaplan traveled all over the world to listen to the performance of this symphony, and discussed his experience with professionals including conductors whenever he had the opportunity. In 1982, he finally stepped onto the stage of Lincoln Center in new york and realized his wish under the witness of many celebrities.

College students are enthusiastic about growing rice, but the new agricultural science is not as simple as farming.

　　"Breakfast, a bowl of boiled rice with pickles, full of rice, sweet back." Eating his own hybrid rice, Liu Haolin, a sophomore majoring in agriculture at the Agricultural College of Sichuan Agricultural University, has an indescribable satisfaction.

　　Recently, the news that sophomores successfully planted hybrid rice appeared in Weibo Hot Search. In late April this year, the Agricultural College of Sichuan Agricultural University held a hybrid rice planting and whole growth period management skill competition. Online registration was full just two minutes after it was opened, and many students failed to sign up. In late September, three hybrid rice plants planted by Liu Haolin’s group successfully passed the teacher’s acceptance. Some people praised and others scoffed at the fact that the sophomore boys planted hybrid rice, thinking that it was just the basic skill of agronomy, and some people thought that studying agriculture was just learning to farm.

　　Does the popularity of planting competition in agricultural colleges mean that planting is a necessary skill for agronomy majors? What is special about the hybrid rice planted in the competition? Under the background of new agricultural science, what changes have taken place in agricultural professional education in colleges and universities? A few days ago, the reporter of Science and Technology Daily conducted relevant interviews.

　　Cutting-edge technology into agricultural competition

　　In the eyes of many people, the major of agronomy is to learn farming, and you can learn how to do species work at home without even going to college, so that the farmland can be productive. However, in Liu Haolin’s view, studying agronomy is to contribute to the national agricultural development. "Agronomy taught me how to greatly increase production, how to scientifically farm, how to cultivate new varieties, etc., which is absolutely different from farming at home."

　　"This is the public’s misunderstanding of agronomy, which is a modern science that uses science and technology to arm crop production." Ren Wanjun, deputy dean of the Agricultural College of Sichuan Agricultural University, said that planting is one of the most basic skills in agronomy, but in addition to its production function, planting is more important to lay the foundation for theoretical research on crop biology and ecology, new variety breeding, cultivation technology innovation and management model innovation.

　　During the competition, in order to let students feel the cutting-edge technology in the field of planting, the college applied the latest achievements of the national key research and development plan to all aspects of the competition.

　　In terms of varieties, combined with the adaptability of mechanical transplanting of hybrid indica rice and the demand for high quality and high efficiency, the competition adopted the newly established variety screening index system with "daily yield" and "good taste" as the core; In the two links of seedling raising and planting intubation protection, the high-efficiency seedling raising technology and the green cultivation technology of high-quality hybrid rice with good quality and high quality are adopted respectively.

　　The college will organize special personnel to carry out training on the technical application of each link. "The purpose of the training is to enable students to personally experience and master these advanced technologies and help them better cultivate rice." Ren Wanjun said.

　　In August, pests first appeared, and Liu Haolin, who wanted to kill insects quickly, accidentally took too many drugs and burned seedlings. As a result, there was no progress when it was time to heading. Liu Haolin, who was thinking about how to feed rice while eating and sleeping, suddenly thought of what the teacher had said in class, so he solved this problem. He said: "Agriculture needs to combine theory with practice. Although there will be setbacks during the competition, the key is to find problems and master methods through practice."

　　"The whole competition is equivalent to laboratory planting, and every link can be managed accurately. Because there are fewer seedlings planted in the laboratory, the lighting conditions and soil conditions are not well planted in the field, so its management is more difficult than field planting, but it also exercises and tests students more. " Ren Wanjun said that for scientific research and teaching, laboratory planting is of great value, because each link is controllable, so we can know more clearly the reasons for some phenomena in each link and determine the effect of each technical measure.

　　He said that any agricultural research results need to be combined with laboratory and field, and repeated experiments. After the results are planted in the laboratory, they need to be tested by field experiments before they can be popularized, which takes a long period.

　　Cross-discipline to create comprehensive talents

　　The fiery competition is actually a microcosm of the construction of new agricultural science. In June this year, the Anji Consensus — — The announcement of China Declaration on the Construction of New Agricultural Sciences marks the official start of the construction of new agricultural sciences in China, and the development of higher agricultural and forestry education has entered a new era. Since the announcement of the new agricultural science, what changes have been made in the education of agricultural specialty in colleges and universities?

　　"The focus of the new agricultural science is to transform the traditional agronomy specialty with modern biotechnology, engineering technology, information science and technology, so we should focus on combining these technologies with modern agronomy and integrating them into the teaching, scientific research and practice of personnel training." Ren Wanjun said that to take the road of innovation and subject integration, we should not only integrate the latest scientific research achievements and modern high-tech into specialty construction and course teaching, but also deepen the interdisciplinary, strengthen the construction of emerging interdisciplinary fields such as mechanized crop cultivation, precision cultivation, intelligent agriculture and biological breeding, put forward new theories and methods, realize the modernization of agronomy, and let universities lead the development of new agronomy.

　　The reporter saw that in the training plan of the college, there are not only basic and professional theoretical courses such as plant physiology, soil and fertilizer science, crop cultivation science, farming science and crop breeding science, but also general courses such as English, ideological and political science, mathematics, chemistry and biology, as well as ideological and political courses for agricultural students to "learn from agriculture and love agriculture" and "strengthen agriculture and promote agriculture". At the same time, interdisciplinary courses such as intelligent agricultural technology and application, agricultural economy and management, plant biotechnology, molecular biology, agricultural industrialization, agricultural standardization and crop production mechanization have also been included in the training plan. Ren Wanjun said that agricultural production should take the modernization road of mechanization, standardization and informationization. As a high-tech discipline, agronomy is a complex comprehensive specialty, so the cultivation of agricultural talents should also be a systematic comprehensive project.

　　Innovation and entrepreneurship take on the responsibility of revitalization

　　"The most distinctive feature of the new agricultural science in our college is to cultivate students ‘ Willing, capable, hardworking and practical ’ ‘ Sigan ’ Traits. " Ren Wanjun said that agronomy itself has high practical requirements. Under the background of new agricultural science, the mastery and application of technology need to further deepen the practical requirements of agronomy. Therefore, it is particularly important to cultivate students’ practical ability and innovative consciousness.

　　"In the process of practical teaching, the most important thing is to cultivate students’ innovative and entrepreneurial ability. In addition to learning the basic operation of planting, students should learn how to solve problems, including theoretical problems, technical problems, production problems, management problems, benefit problems, etc., and constantly optimize their thinking and methods for solving problems. " Ren Wanjun said that agricultural science and technology are constantly developing, and students need to have the ability to innovate, not only to absorb and master new things, but also to continuously develop and create new theories and technologies.

　　In order to closely combine practical teaching with the cultivation of innovation and entrepreneurship, the college has established a training path of undergraduate talents with "indoor and field combination, scientific research transformation teaching, classroom cooperation, innovation and entrepreneurship education". In addition to setting up various skills competitions such as hybrid rice planting and whole growth period management, seed quality testing, specimen making, etc. in the school, the college also allows every undergraduate to "join the team, each with a project", so that every student can enter the teacher’s research team, participate in scientific research projects, and cultivate innovation and entrepreneurship ability in scientific research practice.

　　In addition, the college has more than 30 off-campus practice bases and expert compound, which can carry out teaching and scientific research practice for students to complete course practice and graduation practice, and serve local economic development while being familiar with actual agricultural production and work.

　　Recently, the largest public centralized charging station in Henan Province — — "United Fast Charging" was put into operation in Zhengzhou, and all charging piles were charged with high-power DC fast charging, which can meet the requirements of charging more than 100 new energy vehicles at the same time.

　　After the subsidy retreat, domestic new energy vehicles will not only face competition with traditional fuel vehicles, but also compete with foreign new energy vehicle brands. Impressing consumers with suitable and high-quality products may be the most effective means for new energy vehicle manufacturers to resolve market risks. The core of competition among new energy automobile manufacturers is the competition of product technology and service.

　　With the end of the first half of 2019, new energy vehicles have truly entered the post-subsidy era.

　　Chen Shihua, Assistant Secretary-General of China Association of Automobile Manufacturers, said that the current new energy vehicle market is still a market stimulated by policies, and with the support of national and local policies, it is in a rapid rising cycle. The decline of this subsidy is expected to have little long-term impact on the industry, and the previous prediction of the annual production and sales of 1.6 million new energy vehicles in 2019 will remain unchanged.

　　After waiting and seeing, the price increase is inevitable.

　　June 25th is the last day of the switching period between the subsidy policy for new energy vehicles in 2018 and the subsidy policy for new energy vehicles in 2019. Since June 26th, consumers have enjoyed the most subsidies or reduced them by 58%.

　　"The withdrawal of subsidies mainly takes into account that the development of the new energy automobile industry has begun to take shape." Zhou Yi, assistant researcher of the Ministry of Industry of the State Council Development Research Center, said. Before 2014, the output of new energy vehicles was very small, less than 20,000. In 2014, the output jumped to 78,000. In 2018, the sales of new energy vehicles in China reached 1.256 million, accounting for more than half of the world’s total, with remarkable achievements.

　　In fact, the rapid growth of new energy vehicles in China in the past is inseparable from subsidies. According to the "Announcement on the Preliminary Review of Subsidies for the Promotion and Application of New Energy Vehicles in 2016 and Previous Years" published on the website of the Ministry of Industry and Information Technology in March this year, nearly 12.6 billion yuan of subsidies will be distributed to nearly 100 enterprises, of which BYD will become the biggest beneficiary with 2.689 billion yuan, and Geely will rank second with 1.111 billion yuan.

　　With the subsidy for new energy vehicles declining year by year, independent car companies will naturally be affected to varying degrees, especially whether the price of new energy vehicles will increase, which has become the focus of consumers’ attention.

　　The reporter recently visited some 4S stores in Beijing, such as Chery, BYD and GAC New Energy, and has not seen a clear price increase notice. They are all selling cars at the subsidy standard of 2018.

　　Chen Shihua said, "At present, the profit rate of new energy vehicles is very low, and it is difficult for car companies themselves to bear the reduction of subsidies." "After the subsidy has dropped, the cost of car companies has increased substantially. If consumers do not accept the price increase, it will be difficult for market demand to start effectively." Cui Dongshu, Secretary-General of the National Passenger Car Market Information Association, said that the subsidy for new energy vehicles is much lower than the cost reduction of car companies, and the profit pressure of new energy car companies is greater. Car companies should not only cover manufacturing costs, but also consider the capital cost of subsidies that are not in place, so they will definitely raise prices.

　　Competition will be more intense.

　　"In recent years, in addition to the increase in quantity, the quality of new energy vehicles and the development of industrial chain have also been greatly improved." Zhou Yi said.

　　From the quality point of view, the battery life is generally on the rise. A-class electric vehicles with a standard cruising range of more than 400 kilometers have become the mainstream, and the intelligent interconnection is also developing continuously. The level of automatic driving test is getting higher and higher, and the localization replacement rate and globalization level of parts and components are also constantly improving. From the industrial chain point of view, the upstream and downstream industrial chains of new energy vehicles are more complete, and a number of excellent enterprises have emerged in the fields of power batteries, non-battery accessories and other parts, complete vehicles such as independent brands and new Internet forces, and manufacturing and operation of charging piles.

　　And the fast-growing new energy automobile industry will be affected after stepping on the "brake" of subsidy retreat?

　　"The challenge is that the competition will be more intense in the future." Zhou Yi said that after the withdrawal of subsidies, domestic new energy vehicles not only face competition with traditional fuel vehicles, but also with foreign new energy vehicle brands, and there is fierce competition within domestic new energy vehicles.

　　Lu Fuyong, a lecturer in industrial economy and national economy in university of international business and economics, has been paying attention to the development of new energy automobile industry in recent years. He told reporters that in the era of subsidies for new energy vehicles, there are four aspects of market risks: First, the competition in the overall market will be further intensified, and the subsidy policy will make the competition more intense, and the industry will gradually move toward the survival of the fittest. In this process, traditional car companies still have certain competitive advantages. Second, the real demand of consumers will gradually become clear. In the past, due to the support of policies, the market has always overestimated the real demand of consumers, and it is very likely that the market demand will fall back in the short term. The third is the risk of capital. In recent years, the new forces of car-making have risen rapidly with the help of capital. As the sales of new energy vehicles move from hot to stable, there is uncertainty whether these capitals will still be active in the industry. The fourth is the technical service risk.

　　Lu Fuyong believes that how to grasp the real needs of consumers in the post-subsidy era and impress consumers with suitable and high-quality products may be the most effective means for new energy vehicle manufacturers to resolve market risks. "In the future, the competition of new energy automobile manufacturers will gradually shift to the comprehensive value competition of products, and the core is the competition of product technology and service."

　　Lu Fuyong said that with the growth of new energy vehicles and the extension of service life, traffic and safety accidents related to new energy vehicles will further increase, and the short service life of new technologies will increase product risks; At the same time, new energy vehicles recalled due to product quality problems are also accumulating. The core to solve these problems is still to improve product quality and technical services, which is also the main difficulty faced by new energy vehicle manufacturers.

　　Intelligentization will become the commanding height.

　　"In 2019, China’s automobile market will still run at a low speed, but new energy vehicles will continue to grow. New energy automobile products should be customized in design, intelligent in function and platformized in development. " Shi Jianhua, Deputy Secretary-General of China Automobile Industry Association, said that with the rapid advancement of scientific and technological revolution, the new generation of information technologies such as 5G, cloud computing and artificial intelligence are deeply integrated with automobile transportation and other fields, which constantly promotes the formation of multi-dimensional information interaction networks between cars, roads, people and clouds, and people’s production and lifestyle are undergoing profound changes. Smart cars have become the commanding heights of the future development of the automobile industry.

　　Shi Jianhua believes that in the future, the automobile industry should take green and intelligence as the development direction, and will focus on breaking through the key components of fuel cell technology and related industrial chains, advance the research and development and industrial application of intelligent driving technology, enhance the green and intelligent level of the industry, and accelerate the development of new energy and intelligent networked vehicles.

　　Zhou Yi said that at present, there is a trend of "interconnection, autonomous driving, sharing and electrification" in the global automobile industry, and the networking of vehicles, autonomous driving and electric vehicles are closely related, and with the rise and application of 5G technology, it is expected that the application scenarios of electric vehicles under 5G will be more abundant in the future. In this context, the new energy vehicle market will be polarized in the future, and a few car companies will stand out because of their technical and cost advantages.

　　"Whether new technologies and new industrial formats such as autonomous driving, car networking, intelligent transportation and driverless taxis can be commercialized on a large scale depends entirely on many factors such as cost, technology maturity and consumer acceptance." Zhou Yi said, but what is certain is that China has taken the lead in international exploration in these fields due to its huge market scale and abundant capital market, and it is expected to lead the global development in the future.

＂Innovation Subversion＂ or ＂Life Assistant＂ —— Observation of ＂Artificial Intelligence＂ from Summer Davos Forum

　　Xinhua News Agency, Tianjin, June 29th 　Title: "Innovation Subversion" or "Life Assistant" — — Observation of "Artificial Intelligence" from Summer Davos Forum

　　Xinhua News Agency reporter Bai Jiali and Yin Siyuan

　　"Generative Artificial Intelligence: Friend or Enemy?" "Keep pace with the times: embrace the artificial intelligence revolution and improve the level of artificial intelligence" … … At the Summer Davos Forum held in Tianjin, artificial intelligence once again became a "hot topic" concerned by political and business people, experts and scholars.

　　As a window for observing the world and cutting-edge dialogue, how do guests discuss the relationship between artificial intelligence and human life at this economic event? In their eyes, will artificial intelligence bring "innovation subversion" or become a "life assistant"?

　　Life is closely related to it.

　　At the high-profile Summer Davos Forum, guests from different countries and fields started a dialogue on topics related to artificial intelligence. The reporter observed that a common cognition of the guests was — — With the new wave of artificial intelligence triggered by ChatGPT, artificial intelligence is pouring into all walks of life.

　　The "Top Ten Emerging Technologies Report 2023" published by the World Economic Forum "Fresh" reveals the emerging technologies that will have the greatest impact on the world in the next three to five years. Among them, generative artificial intelligence and artificial intelligence assisted medical care are listed. The report also pointed out that generative artificial intelligence is developing rapidly and will lead to subversive changes in many industries such as education and research.

　　Baidu’s ERNIE Bot, Iflytek’s iFLYTEK Spark Cognitive Model, 360 Group’s 360 Wisdom Brain, and brand-new AI mapping tools are changing our way of life and work.

　　"In the past six months, nearly 100 companies have entered the generative artificial intelligence market." Zhang Yaqin, academician of China Academy of Engineering and president of Tsinghua University Intelligent Industry Research Institute, said at the forum that artificial intelligence will play a great role in intelligent transportation, intelligent internet of things and intelligent medical care.

　　In the forum dialogue, Zhao Yan, chairman and general manager of Huaxi Biotechnology Co., Ltd., mentioned a new scene of artificial intelligence application, which may bring more benefits to future women. She believes that artificial intelligence may be able to play the role of "AI assistant" in the future, assisting professional women to complete their work at special times such as pregnancy.

　　"Artificial intelligence is being applied in all aspects of life and is quietly changing people’s lives." Wang Guan, co-founder of Kezhi Technology and director of the Smart Finance Laboratory of Ningbo Institute of Artificial Intelligence of Shanghai Jiaotong University, said that in the near future, with the blessing of artificial intelligence, people’s lives will undergo tremendous changes.

　　Medical treatment has become a hot spot of application.

　　In the forum, a special robot attracted guests to stop. "This is an intelligent diagnosis robot for depression developed by the R&D team of Tianjin University." The staff introduced the new achievements in the field of brain-computer interface research and development to the guests. "Just wearing a device, you can collect the signals of cerebral cortex neurons and pass ‘ Decoding ’ Achieve a quantitative assessment of depression. "

　　From auxiliary diagnosis, to drug research and development, to medical management, a long history of medicine is colliding with brand-new artificial intelligence, expanding its broad development prospects. The guests predicted that artificial intelligence may become a key promoter of the rapid development of the medical field.

　　According to Liu Jiren, chairman of Neusoft Group, the diagnosis of diseases by artificial intelligence will make our diagnosis process change from relying on the ability of each doctor to relying on calculation and collective wisdom, which will reduce the difference of medical services.

　　"When researchers conduct experiments, it is likely that they can only do ten or one hundred at a time, but with AI, they can conduct a large number of experiments simultaneously and generate massive data." Ina klassen Berg, chief commercial officer of Ginkgo Biological Studio, explained the positive role of artificial intelligence in promoting drug research and development.

　　Zhou Xiaping, senior vice president of Novo Nordisk and president of Greater China, said that enterprises have begun to try to speed up the process of drug research and development by using artificial intelligence tools, and at the same time, use artificial intelligence to help patients better manage chronic diseases.

　　The changes that artificial intelligence has brought to the medical industry are still going deeper. Lu Yimin, general manager of China General Technology Group, said that when the group integrated medical resources, it found that the regionality of medical resources in China was prominent, the deployment cost of innovative technologies was high, and the platform access capacity was insufficient, so the promotion was facing challenges. He believes that with the support of AI, it is possible to solve long-standing problems such as the imbalance of medical resources and improve the quality of primary medical services more effectively.

　　In the future, security "fences" should be set up.

　　While the huge potential of artificial intelligence is rapidly released, how to avoid potential security risks? At the forum, the guests had a heated discussion around this topic.

　　In the face of everyone’s concern, "What jobs will be reduced due to the introduction of AI technology?" Li Dongsheng, the founder and chairman of TCL, believes that new technologies can help improve the revenue and competitiveness of enterprises, thus creating more new jobs and possibilities, so as to achieve a balance between improving labor efficiency and ensuring the well-being of employees.

　　So what areas should we try to use this technology? Wang Guan said that some areas with zero tolerance for errors should not use generative artificial intelligence for the time being, but for repetitive work that allows mistakes to a certain extent, it can take the lead in docking this technology.

　　New achievements in research and development such as brain-computer interface in the exhibition area attract guests to stop. Xinhua News Agency reporter Bai Jiali photo

　　Many guests thought that the biggest problem facing generative artificial intelligence, in particular, was that "there is no way to judge whether the content provided is true or false, and it is possible to fabricate a piece of content to confuse users." Feng Yan, a professor at the Hong Kong University of Science and Technology, bluntly said that in every field that needs to be decided, people have to have the final say, and machines can only provide assistance.

　　"Generative artificial intelligence can improve life, and the biggest problem it faces in the future is how to improve its accuracy." Alex Zhvoronkov, founder and CEO of Yingsi Intelligent, said.

　　In the face of known and unknown risks, Zhang Yi, a senior partner of King & Wood Law Firm, who attended the meeting, believes that firstly, laws and regulations should be rationally used to deal with the risks and impacts brought by artificial intelligence, and a governance framework and standards with broad consensus should be formed through laws to form a security "guardrail" and create a more dynamic development environment under its guidance.

Liu Yuning of Modern Brothers can get a hot search even after watching TV. Is it still the boiling point？

Why are these hot searches boiling? Yesterday’s "Weibo Hot Search List" analyzed the new gameplay of hot search: there are a lot of people, which is the embodiment of hot discussion. Hot search becomes a hot topic after extensive participation and discussion by users, and it will be upgraded from hot to boiling.

This reminds me of a hot search last week: Liu Yuning has a clear voice.

Maybe many people just saw this hot search word and reacted like me: I don’t know who Liu Yuning is. It turns out that he is the lead singer of the modern brothers band from Tik Tok-Ning Ge Liu Yuning.

In 2014, Liu Yuning, guitarist Azhuo and keyboard player Dafei formed the band "Modern Brothers". With the modern brothers’ covers of "Walking", "Telling the truth", "Answer" and "I shot myself" becoming popular overnight, the popularity of the modern brothers became out of control and became a new force in the music world that cannot be ignored more and more.　

The voice of Liu Yuning, a modern brother, is not only spread by the ubiquitous media such as shops broadcasting in streets and lanes, mobile TV in buses and subways, and mobile phones of pedestrians on the road, but also known by people. Even the little tricks he is used to singing are well known by fans.

Last Sunday, in the program "The Masked Singer Will Guess" of Jiangsu Satellite TV, the masked singer who was fully armed made his debut. He not only attracted the attention of the audience with his cool blue mecha, but also attracted the attention of fans more quickly when he opened his mouth. Isn’t he Liu Yuning, a modern brother, with a height of over 180, a unique voice and a stage trick that can’t be changed even if he is hiding in the mecha? Enthusiastic netizens immediately had a heated discussion about his true identity, never letting go of any clues, and shared them on the internet, which instantly sparked hot spots.

Coincidentally, Liu Yuning also updated his Weibo that night, which made some netizens have to wonder whether he deliberately released smoke bombs to hide his identity, in an attempt to confuse people. Therefore, a large number of netizens flocked to Weibo, Liu Yuning, to ask him for proof.

Whether the real identity of masked singer "Super Change" is Liu Yuning has not yet been determined. But good music should be respected. Many people say that the modern brother Ning Ge became popular overnight, but as long as you know his past, you will know how much effort he has made, and no one can succeed casually. Liu Yuning’s eight years of ups and downs and hard work have brought him today’s achievements. After he became famous, he once said that he could win the love of so many people. In fact, those who work hard will shine one day!

Is "super change" a better brother? We’ll lock in Jiangsu Satellite TV’s "Masked Singer Will Guess" at 9: 00 on Sunday night, or open Youku Video at 21: 40 to watch the exclusive online video. See you later!

At the age of 40, it’s time to prevent osteoporosis.

　　After the solar term in beginning of winter, the temperature plummeted. According to the annual clinical consultation, the risk of falls and fractures of the elderly will show an upward trend. This is related to environmental factors such as reduced activity in winter, thick clothes and slippery roads, and also related to physical factors such as aging and degeneration of various organs of the elderly. Today we will focus on the problem of osteoporosis. According to the epidemiological survey of osteoporosis in 2018, 6% of male patients with osteoporosis over 50 years old, 32.1% of female patients, and 51.6% of female patients over 65 years old in China. Our country not only has a high proportion of osteoporosis population, but also does not pay enough attention to osteoporosis. The bone mineral density of people over 50 years old is only 3.7%. In fact, both men and women have entered the early stage of bone loss since the age of 40, and we should prevent osteoporosis from this time.

　　1 minute self-examination of osteoporosis risk

　　By answering the 1-minute osteoporosis risk test of the International Osteoporosis Foundation, you can quickly know whether you have the risk of osteoporosis.

　　1. Parents have been diagnosed with osteoporosis or have been fractured after a light fall.

　　2. One of the parents has a hunchback.

　　3. The actual age is over 40 years old.

　　4. Is there a fracture due to a light fall in adulthood?

　　5. Do you often fall down (more than once last year) or worry about falling down because you are weak?

　　Has the height decreased by more than 3 cm after 6.40 years old?

　　7. Is it underweight (body mass index value is less than 19)

　　8. Have you ever taken steroid hormones such as cortisone and prednisone for more than 3 months (cortisone is often used to treat asthma, rheumatoid arthritis and some inflammatory diseases)?

　　9. Do you have rheumatoid arthritis?

　　10. Have you been diagnosed with gastrointestinal diseases or malnutrition such as hyperthyroidism or hyperparathyroidism, type 1 diabetes, Crohn’s disease or celiac disease?

　　11. Do you stop menstruating at or before the age of 45?

　　12. Have you ever stopped menstruating for more than 12 months except pregnancy, menopause or hysterectomy?

　　13. Did you have your ovaries removed before the age of 50 and didn’t take estrogen/progesterone supplements?

　　14. Do you often drink a lot (drink more than two units of ethanol every day, which is equivalent to 570ml of beer, 240ml of wine or 60ml of spirits)?

　　15. Currently used to smoking or used to smoke.

　　16. Exercise less than 30 minutes a day (including doing housework, walking and running, etc.)

　　17. Can’t you eat dairy products and don’t take calcium tablets?

　　18. Have you been engaged in outdoor activities for less than 10 minutes every day and have not taken vitamin D?

　　As long as the answer to one of the above questions is "yes", it is positive, suggesting the risk of osteoporosis, and suggesting bone mineral density testing or evaluating the risk of fracture.

　　Bone mineral density detection is suitable for the following groups

　　It is not necessary for everyone to do bone mineral density test. Compare the following self-test options to see if you need to have a bone mineral density test.

　　1. Women over 65 years old and men over 70 years old, regardless of other risk factors for osteoporosis.

　　2. Women under 65 and men under 70 have one or more risk factors for osteoporosis.

　　■ A slight collision or fall will cause a fracture.

　　■ Adults with low sex hormone levels caused by various reasons.

　　■ Those with diseases affecting bone metabolism or a history of using drugs affecting bone metabolism.

　　■ Patients receiving or planning long-term glucocorticoid treatment

　　■ Small and thin people

　　■ Long-term bedridden patients

　　■ People with chronic diarrhea

　　■ The answer to the 1-minute osteoporosis risk test is positive.

　　Normal osteoporosis

　　Remember "Five Origins and Three Stages" in Prevention and Control

　　The prevention and treatment of osteoporosis should follow five principles. First, increase bone mass and increase bone peak value; The second is to delay bone loss; Third, inhibit secondary hyperparathyroidism; The fourth is to prevent the first fracture; Fifth, reasonable dietary structure and nutritional composition ratio, quitting bad eating habits, increasing calcium intake, participating in moderate exercise and increasing sunshine.

　　Then, according to these five principles, the measures to prevent osteoporosis can be divided into three stages according to age: primary prevention, secondary prevention and tertiary prevention.

　　The primary prevention of osteoporosis is to start from childhood, to reach the highest bone mass (peak bone mass) in one’s life from childhood and adolescence to around 30-35 years old, with the goal of avoiding or alleviating the occurrence of osteoporosis as much as possible. There are mainly the following measures.

　　Reasonable dietary structure: milk is the most ideal calcium source, with 120mg of calcium per 100ml of fresh milk and a calcium absorption rate of 30%. The daily intake of calcium can be ensured by taking 500ml for adults, 750ml for children and 800ml for adolescents.

　　Choose foods with high calcium content: sesame sauce, shrimp skin, dried seaweed, kelp, milk, bean products and cheese are all foods with high calcium content.

　　Vitamin D intake: The daily intake of vitamin D is 400IU, and the vitamin D content in foods such as cod liver oil, canned sardines, egg yolk, shad and chicken liver is high. Sunlight irradiation is also one of the important ways to supplement vitamin D. Walking in soft sunshine for 40 minutes can ensure the vitamin D needed by the body. It is best to choose the irradiation time before 10 a.m. or after 3 p.m., so as to avoid too strong sunlight damaging the skin and eyesight.

　　Moderate exercise: participating in moderate exercise is helpful to increase bone mass and increase the peak bone mass.

　　Adhere to a healthy lifestyle: not addicted to alcohol and tobacco; Drink less coffee, strong tea and carbonated drinks; Less salt and less sugar.

　　When people reach middle age, they reach the secondary prevention stage of osteoporosis. The core of prevention at this stage is to delay the loss of bone mass in middle age and try to avoid the first osteoporotic fracture. Women aged 40-49 and men aged 40-64 enter the prophase of bone loss: the annual bone loss rate of women is 0.4%-0.6% and that of men is 0.3%-0.5%. Women enter the period of rapid bone loss 1-10 years after menopause, and the rate of bone loss is obviously accelerated, while men do not have the period of rapid bone loss. In addition to food supplement, physical exercise and a good lifestyle, the main preventive methods need to be supplemented with vitamin D and appropriate calcium. The recommended intake of vitamin D for adults is 400IU/d, and the maximum tolerable intake is 2000IU/d. When vitamin D is used for prevention and treatment of osteoporosis, the dosage is 800-1200IU/d..

　　The tertiary prevention of osteoporosis is the stage of mending after the sheep is dead, mainly aimed at the elderly, which is mainly reflected in inhibiting bone resorption, reducing bone turnover rate and preventing accidental injuries and fractures. Osteoporosis can be treated by supplementing calcium and vitamin D and taking anti-osteoporosis drugs under the guidance of professional doctors, so as to avoid osteoporotic fractures and re-fractures as much as possible.

　　Calcium supplementation alone cannot replace treatment.

　　The daily calcium intake standard recommended by China Nutrition Association is: 400mg； from birth to 6 months; 600mg； for 6-12 months; 800-1200mg； under 10 years old; 11-24 years old 1200-1500mg；; 1400mg； for pregnant or lactating women over 19 years old; Postmenopausal and postmenopausal women who did not take estrogen 1500mg；; Take estrogen 1000mg； for postmenopausal and postmenopausal women; Middle-aged male 1000mg；; 1000-1500mg for the elderly.

　　However, calcium supplementation alone cannot replace the treatment of osteoporosis. Osteoporosis patients can’t overcome the obstacle of calcium utilization by bones only by taking calcium orally, so they should be treated regularly under the guidance of doctors.

　　About 30% of elderly people over 60 years old and postmenopausal women have gastric acid deficiency. If they have flatulence and constipation after taking calcium carbonate, they should change to calcium citrate. The absorption of calcium citrate is independent of gastric acid and can prevent kidney calculi, which is especially suitable for those with gastric acid deficiency.

　　However, whether calcium supplementation is needed or not should be decided by consulting a specialist in a regular hospital and doing a bone mineral density examination. There is a threshold for calcium absorption. Excessive supplementation is not only a waste, but also can lead to kidney calculi’s disease, ectopic calcification and atherosclerosis. Kidney calculi, patients with advanced bone metastasis, hypercalcemia and cardiac and renal insufficiency are forbidden to supplement calcium.

I’ve been invisible for several years, and the folding screen is ok again.

Text | Deep Eyes Finance Zhang Wei

The folding screen caught fire in 2022 and the fire spread all the way to 2023.

The title of "the first year of folding screen" was born in 2022, one of the reasons is the high growth of folding screen shipments in 2022. According to IDC data, in the third quarter, China shipped more than 1 million folding screens, up about 246% year-on-year.

More importantly, this transcript of the folding screen was achieved in an environment of overall decline in smartphone shipments. According to the consulting data of Ai Media, the overall shipment volume of China mobile phone market will drop from 560 million in 2016 to 310 million in 2020. In 2021, mobile phone shipments rebounded slightly, but the overall environment is still not optimistic, with an annual shipment of only 350 million units.

It is not only the China market that participates in this folding screen carnival. According to Counterpoint research report, it is estimated that the global folding screen mobile phone market will increase by 52% year-on-year in 2023, reaching 22.7 million units.

You know, since the birth of the folding screen mobile phone, it has always been a niche track because of its relatively small market share, average sales volume and general market response.

When it was launched in the early years, it was also vomited by users because of the high price, obvious screen creases and heavy weight. Then, why did the folding screen, which was not welcomed by capital and market before, grow against the trend this year?

1. Capital betting, folding screen to become a new story?

Behind the fierceness of folding screen mobile phones is the embarrassment that mobile phone manufacturers urgently need to grow.

In the downturn of consumer market, the butterfly effect of mobile phone consumers is triggered: consumers who have no money in their belts naturally reduce their demand for mobile phones, and their replacement rate drops, which leads to a downward trend in mobile phone shipments. From January to November 2022, the total shipments of mobile phones in the domestic market totaled 244 million units, down 20.2% year-on-year.

In this context, as a relatively new product form, folding screen has become a "life-saving straw" in the mobile phone industry, and major mobile phone manufacturers have taken this opportunity to get involved in folding screen mobile phones.

At present, almost all mainstream mobile phone manufacturers have released new folding screen mobile phones, including Huawei’s Pocket S, Samsung’s Galaxy Z Flip4, OPPO’s Find N, Xiaomi’s Mix Fold2, VIVO’s X Fold+, etc., and the competition is fierce.

In 2022, Samsung, Huawei, OPPO, VIVO, Xiaomi and other mobile phone manufacturers released more than 10 folding screen mobile phones. According to the current news, there will be many new folding screen machines released in 2023, and even Apple has rumors that it will release folding screen smart phones in 2023.

In the past, high-end machines competed for chips, image capabilities, screen refresh rates, etc. Now, due to the involvement of smartphones in the Red Sea, technologies have entered a mature stage, and these technologies have been decentralized to low-end machines.

Although mobile phone manufacturers bet on the folding screen market, the herd effect is not fully applicable to consumers. In the era of information explosion, consumers are no longer the lambs to be slaughtered who are completely obedient to others.

On the one hand, from the perspective of mobile phone form, the design of folding screen is more futuristic. Compared with the previous folding screen mobile phones, the subdivision of scenes is one of the factors contributing to the growth of folding screen mobile phones, which means that folding screen mobile phones can radiate a wider range of people, and their product design, size, thickness and operation are different from business scenes, car scenes and game fields.

For example, OPPO Find N2 has not only paid attention to the internal and external screens, but also started to cut into the half-folded hovering, so that the mobile phone has a natural bracket, which brings more brand-new experiences to users from entertainment, and is more abundant in watching videos, photography and other leisure games.

Another example is Huawei’s main "folding screen meta-universe", which starts from smart life and exerts its strength on the external screen, and can obtain the weather, payment, camera, application and other dynamics without unfolding the screen. It can be said that the segmentation scene of the folding screen has jointly contributed to the shipment.

At the same time, the product forms of horizontal folding inner screen, horizontal folding outer screen and vertical folding screen also meet the habits and preferences of different people.

On the other hand, high-end is the only way for most industries to mature, and the mobile phone industry is no exception. According to relevant data, the average selling price of mobile phones in China market has increased from 1500-2000 yuan to 3000 yuan. The sales volume is falling, the average selling price is rising, and high-end mobile phones are increasingly favored by consumers.

In order to enhance the competitiveness of products, mobile phone companies are gradually abandoning the original sea tactics and moving towards the "fine machine" mode. According to the data released by China Xintong Institute, from January to October 2022, there were 308 new models on domestic brands, down 10% year-on-year.

The folding screen just meets the needs of users’ high-end machines. However, compared with the "puffy" folding screen four years ago, the folding screen now is more "material".

Previous folding screens always revolved around two problems: poor quality and high price. The report on the development trend of GFK China Folding Screen Smartphone released in 2022 shows that weight and price are still the core issues that prevent users from buying folding phones.

At the same time, according to the survey data of Ai Media Consulting, nearly 80% of the interviewed users buy folding screen mobile phones for entertainment needs, and the reason why the interviewed users don’t buy folding screen mobile phones is that they are expensive, accounting for 59.5%.

Under the focus of mobile phone manufacturers, according to the folding screen mobile phones recently launched by mobile phone manufacturers, today’s folding screen mobile phones are lighter, cheaper and have stronger endurance. For example, on December 25th, OPPO released the new folding screen flagship machine-—OPPO Find N2, which weighs only 233g and costs less than 9000 yuan.

Like the flagship machine Pocket S launched by Huawei, the weight is controlled at 190 grams while maintaining the screen size; Samsung Galaxy Z Fold4 is only 263 grams; Xiaomi’s MIX Fold weighs only 262 grams. Nowadays, almost all folding screens have controlled the weight below 300 grams, which makes it more convenient for users to use.

The price problem doesn’t stop there, and the price will remain downward. According to the Counterpoint research report, in view of the increasingly fierce competition in the folding screen smartphone market, it is expected that its price will be more close to the people in 2023. It can be said that the folding screen mobile phone confirms its "worth" step by step.

2. Self-developed core parts, "cost reduction" achieved initial results.

In order to change the status quo and make the folding screen realize another spring in the mobile phone industry, mobile phone manufacturers choose to break through from the upstream of the industrial chain.

Previously, in the folding screen mobile phone industry, Samsung not only dominated the industry, but also controlled the main components. According to Fomalhaut Techno Solution in the report, Huawei folding mobile phones Mate Xs and Xiaomi Mix Fold both use flexible screens made by Samsung, and Korean parts account for about 30% ~ 50% of the total.

According to the Monitoring Report of Folding Screen Mobile Phone Industry in China in 2022, the quality problem is the biggest concern for users to buy folding screens. Among the quality problems concerned by consumers, the crease of mobile phone is the most concerned, and hinge technology is the key to the crease problem.

And the main cost of folding screen mobile phone is 69% higher than that of non-folding mobile phone, of which the main cost comes from hinge and screen. According to the data of CGS—CIMB, the BOM cost of Galaxy Fold, Samsung’s first-generation folding screen mobile phone, was 636.7 USD, of which the display module cost was 218.8 USD, accounting for 34.4%, and the mechanical/electromechanical structure cost was 87.5 USD, accounting for 13.7%.

The display module cost of Samsung’s bar phone Galaxy S9+ accounts for 21%, and the mechanical/electromechanical structure cost accounts for 7.9%. From the perspective of BOM cost, screens and hinges are the main sources of the increase in the cost of folding screens.

In order to eliminate "bad reviews" and prevent key parts such as hinges and flexible screens from getting stuck in the neck, China brand has been gradually realized.Domestic substitution. The data shows that the number of patent applications related to folding screen hinge technology in China is on the rise, and the number of patent applications related to folding screen hinge in China is 160 in 2020.

At present, independent research and development of hinge technology has gradually become the core solution of mainstream terminal factories. According to the incomplete statistics of the potential silver optical chain, the hinge technology of various terminal factories has been constantly breaking through and innovating with the release of products, such as the aerospace-grade floating silver hinge of VIVO and the double-rotating eagle wing hinge of Huawei.

On the other hand, the folding screen mobile phone on the market has been optimized from 100,000 times in the early stage to 400,000 times, which is obviously improved.

According to the forecast of relevant industry organizations, the global hinge market for folding screen mobile phones will be 1.267 billion yuan in 2021, and it is expected to increase by 136.8% year-on-year to 2.999 billion yuan in 2022, which shows that hinge technology is the focus of the current breakthrough of folding screen.

Moreover, the domestic upstream display industry has achieved breakthroughs in technology, manufacturing and market, and domestic panel manufacturers such as BOE, Shentianma, TCL Huaxing and Visionox have accelerated the innovation and mass production of flexible screens. According to Omdia data, the global OLED production capacity is expected to increase from 31.51 million square meters in 2021 to 75 million square meters in 2027.

Including the optimization of appearance, Samsung has weakened the width of the hinge and the black edge of the screen, accounting for the external screen of the Galaxy Z Fold.

Judging from the recently released new products, the functions of folding screen mobile phones have become more and more perfect, such as the newly released X Fold+ of VIVO, which continues the characteristics of VIVO bar mobile phones, focusing on battery life and fast charging functions. Similarly, the latest Find N2 released by OPPO also has the function of improving endurance and satisfying fast charging.

3. Has the problem of folding screen been solved?

The folding screen mobile phone market has maintained growth for several consecutive quarters, and the growth rate in the third quarter of this year has also reached a new high. In the forecasts of various institutions, the folding screen market is expected to grow significantly.

So, can this situation be maintained, and who is buying a folding screen mobile phone?

The market is inseparable from the word supply and demand. If there is supply, there will be demand.

From the demand side, users as a whole are younger. The data shows that the young people under the age of 35 among the latest folding screen mobile phone users have increased significantly, accounting for 58.2%. Therefore, the supply and demand sides change rapidly in functions such as battery life and thinness.

In addition, according to the daily interactive big data, users of folding screen mobile phones not only have high requirements for mobile phones, but also have certain pursuits for quality of life. For example, they love to use life sharing apps such as Little Red Book and Public Comment.

From the demand side, the folding screen mobile phone has gradually developed from the ready to the development stage. The oversized screen is no longer as "chicken ribs" as before, but has derived more entertainment, business and other performances in terms of user needs.

However, after a year of focus, have the problems of folding screen phones really been solved?

Of course not. In the process of development, any industry will inevitably encounter different problems.

Even though the folding screen market has maintained growth for several consecutive quarters, the reason for maintaining high growth lies more in the focus of mobile phone manufacturers and the small market scale.

On the whole, the optimization of folding screen market has achieved initial results, but the problem has not really been solved. Different from the big step forward of the industrial chain, the recognition degree of folding screen is still at a low level, whether from product design to personal experience.

Judging from the black cat complaint data, most complaints about folding screen mobile phones are still focused on screen quality.

At present, most social platforms are still full of spit on folding screen mobile phones, and some of the reasons for spit are still the problems that were spit out a few years ago, including but not limited to screen off-line, liquid leakage, black spots and so on.

The main frequency of the folding screen model is not as durable as that of the integrated model, and the damage degree is higher. What is more "fatal" is that the follow-up maintenance cost is also higher. Taking Samsung’s latest Z Flod4 as an example, the price of the inner screen+outer screen assembly has reached 4,460 yuan, even for the lower-priced Samsung ZFILIP 4, the assembly price of the inner and outer screens also needs 2,460 yuan.

In the solution to the screen, the practice of major mobile phone manufacturers is to launch a broken screen saver service. Like Huawei’s Pocket S and VIVO’s Fold+, the official broken screensaver price is as high as 1199. The broken screensaver is not only high in price, but also guaranteed for only one year, which invisibly increases the follow-up cost of consumers.

The development of folding screen is also in line with the "first cause effect". In the early stage of development, due to the product’s too small, high price, fragile screen and other problems, it brought a deep negative impression to consumers, which led to the difficulty of market education in the later stage and the low recognition of the product.

One of the key problems is that the crease of mobile phone has not been verified by the market.

Even with the rapid development of hinge technology, the current folding screen market is still in the development stage. The major mobile phone manufacturers have launched newly upgraded folding screen mobile phones for more than one year, while the average service life of a mobile phone is three years.

The screen material will accelerate the aging speed after being folded for a long time. Although official website publicizes that the current flexible screen can be folded for 500,000 times, it does not rule out the possibility that the screen will be folded because of repeated folding.

According to the observation of "Deep Eyes Finance", the folding screen mobile phone just changes the product form, its functional integrity is not as good as that of the straight smart phone, and the improved functions are basically corresponding to the straight smart phone.

The main highlights of folding screen are split screen and multi-video viewing, but these requirements are not just needed by users and are irreplaceable.

As a high-end series product that has been tempered in the market for four years, its underlying logic is undoubtedly to meet the premise that "the folding screen is indeed better than the ordinary straight mobile phone".

Compared with the straight mobile phone, the straight mobile phone with the same price is obviously better from the processor. For example, Huawei’s Pocket S is equipped with 4G Snapdragon 778 processor, and the price starts at 5988. The P50 released by Huawei last year was equipped with Snapdragon 888 processor, and the price was only 4,088 when it was released.

Hard power is important, and soft power is indispensable. On the whole, the folding screen mobile phone still has a large market space, but when imagining the future, we should also study how to meet the demand side and strive for a larger market share.

The way of reading in the eyes of academicians

　　"Looking at today’s society, the fragmentation trend of reading is relatively strong. This way of learning is short and fast, and knowledge is acquired quickly and lost quickly. If you want to read some classic works, it takes a lot of time and energy, but the results are also great. " Recently, Liu Jiaqi, an octogenarian academician of the China Academy of Sciences and a volcanic geologist and Quaternary geologist, shared his "way of reading" with the public at the National Library’s "Mr.’ s Study" activity.

　　"Reading can not only increase knowledge and talents, broaden horizons, but also cultivate sentiment and gain spiritual enjoyment." Liu jiaqi said that when he was a child, reading was a luxury. Reading is difficult, borrowing books is difficult. At that time, he also thought that he could be a librarian in the future, and reading might be more convenient.

　　In Liu Jiaqi’s view, reading is the way to grow up. His fate is also changed by reading. "My road to study, as Qu Yuan’s poem says, ‘ It’s a long way to go in Xiu Yuan, and I will go up and down for it ’ 。”

　　Under difficult conditions, Liu Jiaqi went all the way from primary school to university, and later went to graduate school, but still felt that what he had learned was limited. In 1978, 10 years after graduation, Liu Jiaqi took the postgraduate exam again and came to Beijing. "I turned 40 when I was 30, and I wanted to drive back the past 10 years."

　　After careful calculation, Liu Jiaqi spent 27 years and 8 months as a student. "Reading is very important for the growth of my life." Liu Jiaxuan said. About how to read? He summed up some experiences.

　　First of all, we should be clear about the purpose of reading. To be wise and skilled, be determined to be a man first, and be determined to be a man first; Don’t fish for three days and dry the net for two days when reading.

　　In the process of reading, we should pay attention to methods and think. "It is better if you can find faults in books." Liu Jiaqi said that reading should be selective, and it is necessary to read good books and classics; It is necessary to combine professional books with non-professional books, scientific books with artistic books, and systematic books with fragmented information. Don’t always indulge in fragmented information.

　　"Reading is not only about growing up, but more importantly, making contributions to the country in the future." Liu Jiaqi studied earth science, and he told young people that in the process of studying, they should also specialize in one line and love another.

　　"I have learned some scientific principles and the principles of being a man through reading, so now I can become a scientific worker and make some contributions to the country." Liu Jiaqi admits that he can study and learn something because of the cultivation of the party, so he should give back to the society.

　　"I hope my friends can read more books and read good books, improve their scientific literacy, develop their scientific undertakings and build a better country." Liu Jiaxuan said.
