　　BEIJING, Nov. 8 (Xinhua)-According to a comprehensive report, the 19-year-old son of an oil dealer in Padra, India, didn’t like studying, so he left home for nearly a month to prove his potential. When the police finally found him, they found the young man wandering around and working, and even sleeping on the street.

　　According to the report, this young man named Taka grew up with a golden spoon and is a student of Wassad Engineering College.

　　On October 14th, he left his hometown of Padra and said that he was going to school. However, Taka did not go to school, but went to Vadodara Railway Station, where he took the train to Delhi and lost contact with his family.

　　The picture was taken from The Times of India.

　　The family found that he had left his mobile phone at home, and there was no news for a long time, so he called the police. The police searched for Taka’s whereabouts according to the surveillance video, but never found his whereabouts.

　　The case seems hopeless, and the police almost want to give up looking for Taka.

　　On November 4th, local time, Taka decided to go to an upscale hotel in Simla to look for a job.

　　The manager of this hotel found that Taka’s face was immature and his clothes were not ordinary, so he doubted Taka’s identity and immediately called the police.

　　When the police found Taka, they found him sleeping on the street, then asked him to show his identity document and confirmed that he was Taka who had been missing for nearly a month, so they quickly informed Taka’s family to reunite with him.

　　When Taka’s family heard the news, they immediately came to Simla to reunite with Taka. Taka’s uncle Ketan said that now the whole family finally breathed a sigh of relief. "We have been having a hard time."

　　It is reported that Taka chose to run away from home because he didn’t like his school and didn’t like studying. He had been to Mumbai, Delhi and Sutela and worked everywhere to make a living. It is said that during Taka’s wandering, he worked as a dishwasher in a road restaurant and a clerk in a small shop.

　　Whether to eat rice or noodles is always a controversial topic. Let’s divide into several questions and take a quick look.

　　Question 1

　　Compared with the staple food made of white flour, which one has higher calories?

　　As far as the calorie of food is concerned, it is not what food is made of, but what it is made of, how much water it contains, how much dry food it has, and whether it is added with oil and sugar. The reason why pasta is generally higher in calories is because of the above two reasons.

　　A lot of pasta needs oil, even both oil and sugar. Most of those foods with stuffing have fat and thin meat stuffing and enough fat. Therefore, compared with rice, these pasta dishes have higher calories, which is understandable.

　　Those pasta without oil and sugar depend on the moisture content. The moisture content of ordinary white rice is usually between 62% and 65%. Except for soft noodles, pasta will probably be lower than this value. For example, the moisture content of steamed bread is about 45%-50%, and the staple bread is even lower, only about 40%. As for dry staple foods such as naan, steamed buns and dry pancakes, the moisture content is even lower.

　　Because the water content is low, eating a little more will increase the calories. Comparatively speaking, rice has more water content, less dry goods and lower calories. If you cook porridge again, it will contain more water and have lower calories in each bite.

　　Therefore, compared with the same dishes, when eating rice or porridge, the quantity is better controlled, and the risk of excessive calories is slightly smaller.

　　Question 2

　　Compared with the staple food made of white rice and white flour, which one has higher blood sugar response?

　　In terms of blood sugar reaction, white rice and white flour food are generally high, depending on the cooking method.

　　Compared with white steamed bread and white bread, the glycemic index (GI) of rice is slightly lower, but not much lower. White steamed bread and white bread are 88, and white rice is 83. Whole wheat steamed bread and whole wheat bread will raise blood sugar more slowly.

　　For those pasta with added fat, although the digestion speed is slow and the blood sugar rises later and lower after a meal, the food with high fat has an adverse effect on the insulin sensitivity of the next meal. Therefore, it is not a good choice for people who need to control blood sugar, and it is not a good choice for people who need to lose weight.

　　Among pasta, pasta and macaroni have the lowest blood sugar reaction, and ordinary dried noodles are lower than steamed bread. Generally speaking, the higher the content of protein in flour for noodle making, the more chewy the cooked taste, and the lower the postprandial blood glucose response.

　　Similarly, rice also has different processing accuracy and processing methods. If you eat germ rice, rice with some brown rice, etc., then under the premise of the same cooking method, the GI value is lower than that of polished white rice. There are also some boxed ready-to-eat rice processed in advance, and the GI value is lower than that of freshly cooked rice at that time.

　　Of course, the GI value of these rice is lower than that of steamed bread and bread. Therefore, from the perspective of blood sugar stability, ordinary rice has a slight advantage.

　　Question 3

　　Is there any rice food with a higher blood sugar response than white rice?

　　Among white rice foods, there are indeed some foods with higher blood sugar response than bread and steamed bread, that is, white rice porridge and glutinous rice food.

　　White rice porridge cooked with refined white rice is very easy to digest because it is boiled to powder, so its blood sugar response is higher than that of white rice.

　　However, these foods are similar to rice. Although the blood sugar peak is steep, it is not easy to cause hypoglycemia. What is more powerful is glutinous rice food. After eating them, not only did their blood sugar rise sharply, but according to the same amount of carbon and water, their postprandial blood sugar was easy to drop below the normal level.

　　So, what if you add oil to glutinous rice food? Blood sugar will rise a little later, but the peak of blood sugar in the later period is big and lasts for a long time. Of course, this kind of food is added with fat and has more calories than white rice, which is not suitable for people who need to lose weight.

　　Therefore, for unhealthy people who have already suffered from cardiovascular diseases or diabetes, glutinous rice foods such as fried cakes, glutinous rice balls and zongzi, as well as refined white rice foods such as rice rolls and preserved egg porridge, need to be controlled even more, because their GI values are really too high, even higher than ordinary white rice.

　　Therefore, from the perspective of controlling blood sugar, glutinous rice food is the worst, worse than white bread and steamed bread.

　　Question 4

　　How to match rice food and pasta with whole grains?

　　Rice can be incorporated into countless kinds of whole grains and legumes to make miscellaneous grains rice. Half white rice and half other miscellaneous grains (most of which need to be soaked in advance) actually taste very fragrant. It is also very simple and convenient to add some diced sweet potatoes, Chinese yam slices and taro seeds when steaming rice.

　　Flour can also be added with about 20% of miscellaneous grains powder to make steamed bread, cakes, pancakes, bread and so on. However, when the addition amount exceeds 20%, the taste of pasta will become worse because gluten is seriously diluted. A small amount of mixed bean powder can be added to the noodles, which makes the taste smoother. You can also add oat flour, buckwheat flour, corn flour, etc., but the toughness of the noodles is reduced, and the cooking method is different. Home-made technology is difficult, and the overall popularity is not high.

　　Therefore, from the convenience of adding whole-grain miscellaneous beans and potatoes, rice has a slight advantage.

　　Question 5

　　Are there enough dishes to accompany the staple food?

　　Although the postprandial blood sugar response of white rice is higher than that of noodles, jiaozi and Melaleuca Cake, many people find that eating rice has better blood sugar control effect than eating these pasta, and it is also less likely to gain weight. Why is this?

　　To a large extent, this is because of different eating methods and different contents.

　　In addition to the low nutritional value of white rice, there are advantages in food collocation when eating rice. We seldom just eat a bowl of rice, but we have meat, fish, eggs, bean products, and vegetables, and usually there are more dishes than rice. This makes it easier to obtain relatively balanced nutrition.

　　When eating noodles, there is a big bowl of noodles, and there are only a few dishes and marinades. Therefore, from the perspective of fully cooperating with various dishes, rice is still slightly dominant.

　　Question 6

　　Which vitamin is more, rice or pasta? Which is safer?

　　Comparing rice with white flour one-to-one, protein and B vitamins in white flour are slightly higher. However, the disadvantages of rice are not so obvious after matching dishes. Rice with a large number of dishes, compared with noodles and cakes with few dishes, nutrition will win.

　　From the safety point of view, rice food rarely has allergic problems, while some people eat flour with the risk of "chronic gluten allergy". For these allergic people, wheat gluten will damage the intestinal mucosal barrier, which may lead to chronic allergies to other foods. Severe wheat gluten allergy may even lead to "celiac disease". Such patients can lead a normal life only if they are completely away from all foods containing flour.

　　Generally speaking, rice food and pasta have their own advantages and disadvantages. Whether it is white rice or white flour food, eating more is not conducive to preventing diabetes and cardiovascular and cerebrovascular diseases, nor to losing weight. Appropriate inclusion of whole grains is a better choice. For people who need to lose weight and prevent chronic diseases, reducing the oil and salt in the staple food, including some whole-grain miscellaneous beans and more vegetarian dishes are the key points to eat the staple food healthily.

　　Text/Fan Zhihong (director of China Nutrition Society, chief expert of science communication hired by China Association for Science and Technology)

　　The project involved in the 863 Program is actually a study on the safety of functional food, and the purpose of the study is not to extend the life.

　　On December 5th, Weibo, the official website of Wang Laoji, announced that according to the research results of the National 863 Program, drinking Wang Laoji can prolong life span by 10%. After this statement was released, it was quickly questioned by netizens about the authenticity of the project and the scientific nature of its conclusions. Beijing Youth Daily reporter found that herbal tea brands such as Wang Laoji were indeed used as experimental objects in a sub-project of the 863 Program. However, according to the introduction of Guangzhou CDC, which participated in the project, the center has only done relevant experiments on rats, and it is not sure that the effect of "prolonging life" is also applicable to humans. Many experts in related fields said that there is no functional food, even medicine, that can claim to prolong human life by 10%.

　　Wang Laoji claims to prolong his life by 10%

　　On December 5th, a news about herbal tea Wang Laoji was widely spread on the Internet. Li Chuyuan, chairman of Guangzhou Pharmaceutical Group, announced at a forum that the research results of the National 863 Program show that drinking Wang Laoji can prolong life by about 10%. But soon this news caused a lot of questions.

　　The first person who questioned this idea was the CEO of Huada Gene in the same industry. On the afternoon of the 5th, Weibo, the official of Wang Laoji, announced that Li Chuyuan, chairman of Guangzhou Pharmaceutical Group, had a high-end interaction with Yin Ye, CEO of Huada Gene, and other guests at the China Medical Industry Forum. Li Dong said that "according to the research results of the National 863 Program, drinking Wang Laoji can prolong the life span by about 10%", which was immediately highly recognized by President Yin Ye of Shenzhen Huada Gene Co., Ltd. and warmly applauded by all the guests.

　　On the afternoon of 6th, Yin Ye, CEO of BGI, forwarded the Weibo and explained that the so-called "high recognition" was just a courtesy nod. He said: "Although I am in the same industry and drink Wang Laoji, it does not mean that I recognize this conclusion. The extension of human life span is a comprehensive issue, and so far no single factor can form such a significant difference. "

　　In addition to peers, many netizens have also left messages under Wang Laoji’s official Weibo, saying, "Believe in advertising, you can prolong your life by 100%, just give your brains.". Others questioned, "How is 10% calculated? So many health products in China didn’t dare to say that, and finally lost to a drink seller. ".

　　Previously, it was caught in the "life extension storm"

　　The reporter of Beiqing Daily found that this is not the first time that Wang Laoji claimed that he has the effect of prolonging his life. On June 13th, 2013, GPHL held a special press conference, saying that "Wang Laoji Herbal Tea has the function of prolonging animal life".

　　At the press conference, GPHL said, "Through a two-year safety test on 576 mouse samples, it was initially found that the survival rate of rats in the experimental group of Wang Laoji herbal tea was better than that of the control, indicating that Wang Laoji herbal tea has the function of prolonging animal life … …”

　　At that time, it was not long before Guangzhou Pharmaceutical officially recovered the brand of Wang Laoji, and the news about "Wang Laoji prolonging life" immediately caused widespread doubts. Some netizens said, "How long does it take to extend the life of animals to be scientifically verified? It was less than two years before Guangyao officially recovered Wang Laoji, and this magical result was actually measured! " Others ridiculed, "After Radix Isatidis, another dose ‘ Shenyao ’ Available. "

　　Despite the surging doubts, the relevant person in charge of Guangzhou Pharmaceutical firmly believed in the authenticity of the efficacy of prolonging life when interviewed by the media, and said that this was only a phased achievement, and the next step would be to continue research.

　　Sure enough, on January 6, 2016, Wang Laoji once again released a "breakthrough" scientific research achievement: according to national standards and US FDA standards, the three-year safety system study of the first herbal tea product in China showed that long-term drinking of Wang Laoji herbal tea could prolong the life of animals.

　　According to reports, this conclusion is the first herbal tea project in the National 863 Plan. Guangdong Provincial Center for Disease Control and Prevention, as a scientific research unit, undertook the research on functional food safety evaluation factors.

　　"According to the requirements of national standards and American FDA standards, the research group conducted a two-year safety system study on mouse samples, and found that the survival number and expected average survival time of the experimental group of Wang Laoji herbal tea were higher than those of the control group. The statistical survival time of the experimental group of female rats given 2.90g/kg BW of Wang Laoji herbal tea was 708.2 days, while the statistical survival time of female rats in the control group was 675.1 days, which was 33.1 days higher. The difference was obvious, which proved that drinking Wang Laoji herbal tea for a long time could prolong the life of animals. At the same time, related research was carried out according to the human consumption rules of functional foods, and it was found that the physical examination indexes such as liver and kidney function, blood lipid classification and blood routine of the subjects, respiratory system, digestive system, urinary system and mood all improved to some extent, which proved that drinking Wang Laoji herbal tea for a long time had a positive effect on health. " Although specific data have been released, Wang Laoji’s function of "prolonging life" has not been widely recognized because the report only involves experiments related to rats.

　　As for the "life extension" storm, Wang Laoji responded on the evening of December 6 that the conclusion of life extension was obtained from 576 rat samples, and the relevant statements were basically consistent with the information released in 2016.

　　Survival rate is mainly used for safety verification.

　　On December 6, Huang Junming, director of the Institute of Health Toxicology of Guangdong Provincial Center for Disease Control and Prevention, admitted to the reporter of Beiqing Daily that the center had indeed participated in related 863 projects. "This project exists, and the project number is 2010aa023001. However, we only participated in the experiments of early rats and were not responsible for the human experiments. "

　　According to Huang Junming, the members of this 863 research group include several universities, several research institutions and many enterprises. At that time, it was a huge project, herbal tea was only one of the sub-items, and our team was responsible for part of the work.

　　He recalled the operation of the project to the reporter of Beiqing Daily. At that time, there were three herbal teas participating in the experiment. Among them, Jiaduobao and Wang Laoji’s experiments involved the survival rate of rats, both in red cans and green boxes. Another brand product does not involve this indicator. "Our animal experiments mainly focus on the safety of herbal tea, and the final survival rate of rats is an index to investigate the results." Huang Jun Ming said, "The experiments in which Jiaduobao and Wang Laoji participated were successful, and the animal survival rate reached the previous experimental design. The fact of the experiment was that the rats who used herbal tea lived longer than those who did not."

　　Huang Junming repeatedly stressed: "The survival rate is only the result of our experiment, not the purpose of the experiment. As to whether Wang Laoji has the function of prolonging life, I can’t give a conclusion. As for how the company publicizes, it is beyond our control. "

　　When asked about the funding of this scientific research project, Huang Junming said that all scientific research projects are supported by funds. In addition to the higher-level funding, all units that undertake the project also have inputs. "At that time, Wang Laoji, Jiaduobao and another herbal tea company provided strong support in terms of samples, materials, production, processing and experiments, which ensured the smooth progress of the project."

　　A staff member of the Guangdong Provincial Center for Disease Control and Prevention said that the research results released by Wang Laoji only mentioned about 10% of the experimental results, but did not provide specific experimental details and experimental data, and even the experimenters did not mention it. "The result is very vague and the words are unknown, so we are also verifying it further, but we are not responsible for this experimental result for the time being."

　　Expert: Herbal tea is not suitable for everyone.

　　Wang Fengzhong, deputy director of the Institute of Agricultural Products Processing, Chinese Academy of Agricultural Sciences, said that because rats and humans belong to different species, the conclusions obtained in rat experiments may not necessarily apply to humans.

　　Wang Fengzhong said that related efficacy tests often require a series of animal tests such as fruit flies, rats and monkeys, and finally human trials. Due to the complexity of human body structure, many ingredients that work on animals may have little effect on human body. "If we want to prolong human life by 10%, we need to prolong life by at least 30% in rat experiments."

　　Wang Fengzhong introduced that at present, there is no such thing as "prolonging life by 10%" in the related experiments of functional foods. "Now no one dares to say that it can improve human life span by 10%, and even drugs dare not claim to have such effects."

　　Wang Fengzhong said that herbal tea is not suitable for everyone to drink. "Every product has its optimal population, and it is impossible for a certain product to cure all diseases. Just as some people are allergic to eating eggs, herbal tea cannot be beneficial to everyone. "

　　Fan Zhihong, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, told the reporter of Beiqing Daily that to prove that Wang Laoji has a certificate of life extension, it is necessary to produce accurate research data. "The conclusion without data is unbelievable from my personal point of view", and there is no related research on whether it is vitamin drinks or energy drinks.

　　Fan Zhihong said that this kind of research on life extension needs to be followed for many years, and the sample is very large, and all kinds of mixed factors should be avoided, that is to say, other factors affecting life should be excluded to prove that only one factor has an impact.

　　Fan Zhihong said that she didn’t know much about the traditional Chinese medicine ingredients in the formula of Wang Laoji herbal tea, but as a high-sugar beverage, it was not suitable for everyone to drink. In addition, from the perspective of publicity, it is not appropriate to highlight the life-extending effect of products. Ordinary food cannot publicize its efficacy, even if herbal tea belongs to health care products, "prolonging life" is not among the efficacy of health care products.

　　The reporter of Beiqing Daily inquired from the website of china food and drug administration that the food and beverage branch of Guangzhou Wanglaoji Pharmaceutical Co., Ltd., the parent company of Wanglaoji Herbal Tea, registered its products as plant drinks, which means that Wanglaoji Herbal Tea is a beverage and not a health care product.

　　According to the relevant provisions of the Technical Specification for Inspection and Evaluation of Health Foods (2003 edition) issued and implemented by the Ministry of Health in 2003, health foods with health claims can declare 27 functions such as enhancing immunity, antioxidation, assisting in improving memory, relieving physical fatigue and losing weight, which does not include the function of prolonging life.

In the field of B-class SUV, there has never been an all-round hunting SUV, which requires not simple, high face value, strong power, advanced technology and intelligent driving. On the one hand, we need to be versatile, on the other hand, we must be good in every direction.

At present, BYD is the only car company that can launch such models on the basis of ensuring sales. Recently, Douge tested the brand-new 2025 model and experienced its performance in all directions. Brother Dou believes that it is very difficult to do well in these aspects in this level of field. Let’s take a serious look at this 2025 Song L EV today, shall we?

The key point is that -DiPilot 100, a high-order intelligent driving assistance system of "Eye of the Gods", has a total of 29 sensor devices, including 5 high-precision millimeter-wave radars, 2 forward-looking cameras, 1 rearview mirror camera, 4 side-looking cameras, 4 panoramic cameras, 1 DMS camera and 12 ultrasonic radars. This hardware configuration is very rare in many vehicles of the same class.

So what function can it achieve? Because everyone is curious about how to use this set of "eyes of the gods"? High-speed navigation (HNOA) means being able to get on and off ramps, overtake, merge lines, keep lanes and so on at high speed. The basic ACC adaptive cruise, ICC lane navigation and ILCA lane change can be easily realized, and the mainstream intelligent auxiliary functions are realized. These functions have been seen in many videos and pictures before, and today we focus on this, parking assistance.

This parking aid includes remote parking and automatic parking. Remote parking is connected to the vehicle through a mobile phone. We have tested this and it is very smooth, especially when encountering a very narrow parking space. Focus on automatic parking, which is to cooperate with the sensor equipment mentioned above to realize automatic parking. We are in a closed extreme road position. As you can see, this parking frame is very small and extreme, and it is basically the same as the 2025 Song L EV. When we use automatic parking in the car, we found that Song L EV is very silky and accurate, which should be praised.

On the one hand, this function reflects BYD’s technical skills in intelligent assisted driving, on the other hand, it really facilitates urban car use, solves parking anxiety and brings tangible benefits to everyone. Then we are at the scene, not to mention that this function is not easy to use, and we really have to meet a very extreme position. This automatic parking can save a lot of time.

From the perspective of the entire B-class car, the 2025 Song L EV has a high face value, and the shape of the slip back is actually a feeling of Z9GT with a high face value. As for the interior, it actually matches the appearance value, which is very in line with the young people’s aesthetics of hunting cars, clean and tidy, and very advanced.

Generally speaking, after experiencing the 2025 Song L EV with the "Eye of the God", I really feel that more consumers will be willing to consider this B-class hunting SUV. I want to have a face value, space and space, and be smart and intelligent. Brother Dou will not hesitate to give it one more label, that is, omnipotence. If there is a chance, everyone can go for a test drive!

　　This newspaper (reporter Zhao Xin) went shopping, and I don’t know how many citizens paid attention to the songs played in the store. Yesterday, the Internet began to spread that "the sudden change of songs in shopping malls is a mysterious hint", reminding consumers that hot songs are "anti-thieves". Is there such a "hint"? Yesterday, reporters contacted many shopping malls in Wuhan, and some shopping malls said that this prevention mechanism does exist. Have you ever encountered such a "hint" when shopping?

　　"pay attention! The change from soothing songs to energetic songs in shopping malls is to remind people who are used to stealing admission. " Yesterday, netizen @ Oregon Seven Sisters said that she tried on shoes when she was shopping in the mall many years ago. The light music originally played turned into a strong song. The salesperson told me that there was a habitual thief entering the mall. After the security guard found it, he informed the studio to remind him. This blog post was forwarded by the majority of netizens, saying that they had encountered similar situations. Some netizens also expressed doubts, saying that the sudden change of genre may be just a coincidence.

　　Is there such a "secret code" in the mall? Do local shopping malls in Wuhan have their own reminder system? Yesterday, the reporter found out from Guoguang, World Trade Organization, China Merchants, Qunguang, Ikea Huiju and other large shopping malls that some shopping malls did implement this code law. According to the staff from Qunguang, they will use this method to remind employees that there are fixed tracks for different phenomena, but the song list is not convenient to publish. The gathering of Zhongshang Square and IKEA also indicates that there are similar early warning methods. "In fact, this is just a sudden emergency mechanism." According to the relevant person in charge of a shopping mall, the public security environment and security have improved, and it is difficult to use the song-changing code. If thieves appear, they will directly intercept them at the scene to create a safe shopping environment for the citizens.

　　Recently, General Secretary of the Supreme Leader stressed during his inspection tour in Chongqing: "Continue to deepen the rectification of formalism to reduce the burden on grassroots and create favorable conditions for grassroots cadres and officers to start businesses." Since the General Office of the Central Committee of the CPC issued the Notice on Solving Prominent Formalism Problems to Reduce the Burden for Grassroots Units, various regions and departments have made continuous efforts to solve a number of outstanding problems. Grass-roots cadres are at the end of social governance. Only by clarifying the boundaries of powers and responsibilities, improving the mechanism of reducing burdens, and cultivating grassroots talents can the majority of grassroots cadres go into battle lightly, display their fists and feet, and really spend their energy on doing practical things.

　　To "delimit" the responsibility and authority, forgrass rootscadreminusNegative.It is necessary to strengthen the management of the list of powers and responsibilities. First, the list of powers and responsibilities of the higher authorities about the grass-roots work, and clarify which work of this department should be participated by the grass-roots; The second is the list of work scope of grass-roots units, which determines the responsibilities that grass-roots units should undertake. People should do things according to their responsibilities and things should be done according to the system. By strengthening the management of power and responsibility list, standardizing and optimizing the scope of authority, all parties have clear responsibilities and do their best, so that the grassroots are no longer the "takers" of various responsibilities and matters, so that grassroots cadres can spread their shoulders and have more time to walk the streets and serve the masses.

　　giveInstitutional mechanism "empowerment",forgrass rootscadreminusPress.It is necessary to work hard to establish a long-term mechanism, improve and perfect the work mechanism of burden reduction, which is coordinated from top to bottom, left and right, and coordinated by departments, and highlight the role of functional departments such as organization department, discipline inspection commission, and editorial office to form a joint effort to reduce burdens. Make good use of this family heirloom, go to the grassroots to find out the reality, understand the worries and difficulties of grassroots cadres, and solidify the mature experience and effective measures that meet the expectations and needs of grassroots in the process of burden reduction to form a long-term mechanism for grassroots cadres to learn from.

　　Pave the way for growth and talent, and reduce worries for grassroots cadres..It is necessary to optimize the assessment and evaluation system, ensure that the index setting is focused on the grassroots, scientific and reasonable, promote the transformation from "quantity examination" to "quality examination", and truly play the role of assessment "baton". It is necessary to activate the "spirit" of cadres, motivate cadres with their careers, and send a group of grassroots cadres to major reforms, important positions and key projects to overcome difficulties, so that grassroots cadres who want to be officers, can be officers and succeed can stand out. It is necessary to implement the fault-tolerant and error-correcting mechanism, strictly implement the "three distinctions", comprehensively analyze the mistakes of cadres, boldly tolerate the fault-tolerant ones according to the procedures, and earnestly take responsibility for the cadres who dare to take responsibility and be responsible for the cadres who dare to take responsibility.

　　In short, only by establishing a clear orientation of reducing the burden on the grassroots and supporting the hard work can we really activate the "one pool of spring water" for grassroots cadres to perform their duties conscientiously and actively, so that grassroots cadres can spend their time and energy on the "cutting edge" and exchange more hard work for the people’s happiness, sense of acquisition and sense of security.

Richmond Fed President: The US economy is in good shape, and the Fed can meet the challenge calmly.

Thomas Barkin, president of the Federal Reserve Bank of Richmond, said that the US economy is in good condition, which enables the Fed to reduce borrowing costs. Barkin delivered a written speech at the Together Summit in Baltimore on Tuesday, saying, "Strong but more critical consumers, more productive and valuable labor force keep the economy in a good state. No matter how the economy develops, the Fed can respond appropriately. " The president of the Richmond Fed said that consumers who are increasingly sensitive to prices are helping to curb inflation. As companies retain talents, the labor market remains flexible. Part of the reason for the increase in productivity is that companies have invested in automation during the epidemic and have a more experienced workforce with a low turnover rate.

Federal Reserve Kashkali: If inflation unexpectedly rises before December, it may make the Fed suspend interest rate cuts.

Federal Reserve Kashkali said that considering the dynamics of the housing market, it may take one to two years for the inflation rate to drop to 2%; I don’t want to declare victory over inflation, but I have good reasons to maintain confidence. The strong labor market is "encouraging" and the economy looks strong. If inflation unexpectedly rises before December, it may make the Fed suspend interest rate cuts. In an environment with high productivity, the neutral interest rate is higher, which means that the Fed has less room to cut interest rates. The threshold for the Fed to stop shrinking its table is still quite high, and there is still a long way to go before it ends. The extent to which the Fed cuts interest rates will depend on the performance of the US economy.

Boeing says it will take several weeks to fully resume production after the strike.

On November 12, local time, Boeing Company of the United States said that it would take several weeks to fully resume the production of passenger planes because the factory workers returned to work after nearly two months of strike. A Boeing spokesman said that the delay in the resumption of work at factories in Washington and Oregon in the United States was due to the need to take multiple steps to resume production. Every employee will be informed of his responsibilities and safety requirements after returning to the company, and the company will ensure that the training certificate is up to date. It is reported that this strike is due to the breakdown of the negotiations between Boeing’s employers and employees to renew the contract. Boeing employees voted against the salary plan proposed by the management in mid-September, and then about 33,000 employees began to strike. Last week, employees voted to accept Boeing’s contract invitation and return to work before November 12. According to reports, the strike caused the production of Boeing 737 Max, 777 and 767 models to stop.

　　Our reporter Cao Xiuying

　　"Charging anxiety" and "mileage anxiety" are a major obstacle to the large-scale industrialization of pure electric vehicles. At the 2019 World New Energy Vehicle Conference held recently, a technology called "High Specific Energy Fast Charging Lithium-ion Battery" won the Global New Energy Vehicle Innovation Technology Award.

　　This technology breaks through the technical bottleneck that graphite system can’t charge quickly. On the basis of maintaining the advantages of high energy density, high safety and long life, it can complete 100% charging within 15 minutes, ensuring the cruising range of electric vehicles of 300 kilometers.

　　What is the secret of this technology? How can we realize the fast charging of electric vehicles and make new energy users feel the convenience of "charging for five minutes and talking for two hours" like mobile phones?

　　At present, the fast charging methods in the industry have disadvantages.

　　As we all know, for pure electric vehicles, the charging and discharging performance of battery system is an important index to determine the actual use effect of vehicles. High energy density and fast charging ability are not only the technical direction that power battery manufacturers are constantly striving to develop, but also the core field of new energy technology.

　　"Lithium-ion batteries are also called rocking chair batteries." Cheng Xiaoyan, director of scientific research project of Contemporary Amperex Technology Co., Limited New Energy Technology Co., Ltd. (hereinafter referred to as Contemporary Amperex Technology Co., Limited), told the Science and Technology Daily reporter that the two ends of the rocking chair are the two poles of the battery, and lithium ions run back and forth at both ends of the rocking chair. When charging, lithium ions move from the positive electrode of the battery to the negative electrode through the electrolyte. Graphite, as a negative electrode, has a layered structure, and lithium ions are embedded into the graphite through the interlayer. The more lithium ions are embedded, the higher the charging capacity is.

　　A key index to measure the charging efficiency of electric vehicles is the charge-discharge ratio (C). The rate of charge and discharge can be simply understood as the rate of charge and discharge. The charge and discharge rate of lithium-ion battery determines how fast we can store a certain amount of energy in the battery or how fast we can release the energy in the battery. For example, when a battery with rated capacity of 100 A is discharged with 20 A, its discharge rate is 0.2C, and the used capacity is discharged within 1 hour, which is called 1C discharge; After 5 hours of discharge, it is called 0.2C discharge.

　　It is generally believed in the industry that fast charging of electric vehicles refers to the charging method with a charging rate greater than 1.6C, that is, the technology that takes less than 30 minutes from 0% charging to 80% charging.

　　As the name implies, to shorten the charging time, it is necessary to continuously improve the charging and discharging rate. The core of fast charging technology is to accelerate the speed of lithium ion moving between positive and negative electrodes through chemical system and design optimization. However, it is not enough to consider speed when developing fast charging technology.

　　During fast charging, lithium ions need to be embedded into the negative electrode instantaneously. This is a great challenge to the ability of the negative electrode to receive lithium ions quickly. In the battery of common chemical system, lithium and other by-products will appear in the negative electrode during fast charging, which will affect the cycle and stability of the battery core. Only negative electrode materials that can withstand fast charging and high current can be used to achieve fast charging.

　　Cheng Xiaoyan said that at present, lithium titanate and amorphous carbon are widely used as negative active materials in order to realize fast charging. However, both lithium titanate and amorphous carbon inevitably have the defects of serious shortage of energy density and high cost in practical application. The conventional design of increasing the amount of conductive materials will also affect the energy density of batteries. "In recent years, some manufacturers have begun to explore graphite as an active material, but the problem faced by graphite as a fast charging material is how to quickly release lithium electrons from the anode and then quickly enter from the cathode."

　　Cheng Xiaoyan explained that graphite is more like a highway. Although the energy density is higher, lithium electrons can only pass through in sequence.

　　In other words, graphite is not a natural material suitable for fast charging technology. "But we use technology to break through the bottleneck of the material itself, and its killer is ‘ Fast ion ring ’ And ‘ Superelectronic network ’ 。” Cheng Xiaoyan sighed.

　　The fast ion ring and the super-electron net accelerate the charging.

　　"We use graphite as the main material of the negative electrode, and innovatively use channel optimization and ‘ Fast ion ring ’ Technology, to create a circle of high-speed channels on the surface of graphite, so that lithium ions can be quickly embedded in any position of graphite, which greatly improves the embedding speed of lithium ions in the graphite cathode. Moreover, the modified graphite has the characteristics of super fast charging and high energy density, and there will be no by-products at the cathode during fast charging, which will affect the cycle and stability of the battery. " Cheng Xiaoyan said.

　　In addition, the technical team developed the "super-electronic net" technology to modify the cathode material, and combined with the crystal orientation and capacity excess coefficient of the anode and cathode plates to optimize the dynamic properties of the electrolyte and anode and cathode, so that the chemical system and battery design parameters can be optimally matched.

　　"Generally speaking, ‘ Fast ion ring ’ And ‘ Superelectronic network ’ It acts on the cathode and anode respectively, establishing a fast channel for a large number of lithium ions to flood into the cathode at the same time, and improving the diffusion rate of lithium ions. " Cheng Xiaoyan said.

　　In addition, in terms of mechanical parts design, the team creatively simplified the design of the battery cell top cover, set the electrode terminals to the side of the top cover plate and reduced the terminal thickness, significantly reduced the internal resistance, effectively controlled the heat generation of fast charging, and ensured the reliability of fast charging while improving the energy density by more than 5%.

　　"Our fast charging technology has 4C— 5C fast charging capability, achieving 10-mdash; 15-minute fast charging, compared with the fast charging system of lithium titanate cathode, has obvious energy density and cost advantages, and compared with other fast charging technologies in the industry which also use graphite as cathode, it can increase by 20%— 30% charging speed, and better cycle and weather resistance. " Cheng Xiaoyan said.

　　It has been successfully applied to more than 5000 buses.

　　At present, the super lithium-iron fast-charging battery developed by Contemporary Amperex Technology Co., Limited with fast-charging graphite as the main negative material has been applied to more than 5,000 electric buses, and the buses are in good running condition, which has been well received by vehicle manufacturers and bus users, and the battery has also been rated as "the best word-of-mouth battery for new energy buses" by the Ministry of Communications.

　　In addition to its energy density, the battery has a great advantage. In terms of cycle life, taking buses with harsh application conditions as an example, it is fully charged and discharged about twice a day on average. Roughly speaking, it can meet the operating requirements for 8 years, and the battery needs more than 5,600 cycles. The cycle life of super lithium iron battery cells can reach 10,000 times, which not only fully meets the operating needs of electric vehicles, but also can be used for energy storage and other cascade utilization after retirement, creating more economic value.

　　"In order to ensure the safety and reliability of the fast charging core, we have also developed special technology to identify the ‘ of the chemical system at different temperatures and SOC states. Healthy charging interval ’ , and then in this ‘ Healthy charging interval ’ Fast charging within the range can not only achieve fast charging, but also prevent the battery from being damaged by fast charging, so as to achieve fast charging, long cycle and safety and reliability. " Cheng Xiaoyan said.

　　In terms of weather resistance, in order to meet the requirements of low-temperature charging in northern winter and high-temperature working conditions in southern summer, the technical team specially developed an efficient thermal management system to ensure that the battery is in a reasonable temperature range. The battery core can be heated quickly at low temperature, and the fast charging mode can be started when the temperature meets the requirements; At high temperature, the system will cool down the battery, and truly achieve "all-weather" fast charging.

　　"We are developing 2C— with monomer energy density greater than 160 WHr per kilogram; 2.5C fast-charging lithium iron battery with high energy density and long life (more than 6000 cycles) is expected to be mass-produced by the end of 2019. At the same time, this technology has been applied and developed to the ternary system passenger car, which has achieved 350 kilometers of battery life and completed charging within 15 minutes. " Cheng Xiaoyan said that the company also plans to be in the next 1-mdash; Within two years, the ternary power battery product with energy density as high as 255 watt-hours per kilogram will be launched, which can be quickly charged within 18 minutes.
