MFI? Mi For iPhone! Why is Xiaomi magnetic power bank better than the original and other competitors!

Now smartphones are stronger than one in battery life. When the iPhone13 Pro Max was just released, it once became the best battery life among all smartphones, but the charging speed iPhone has always been the most pulled! No matter how good the battery life is, you will also encounter friends with power anxiety. The traditional power bank is big and heavy. Once Magsafe came out, it attracted much attention. Why only pay attention? After all, the price of 799 is too outrageous!

I also happen to be a person with power anxiety disorder. After searching for a large number of videos of various power banks, I chose magnetic power banks as my purchase target, and among many brands, I finally chose Xiaomi magnetic power banks! This stuff is not expensive, it is not for promotion. Let’s talk about why I chose it below.

Xiaomi magnetic power bank belongs to the category of magsafe in appearance, and the overall feel is based on a sentence of Xiaomi’s previous products: warm as jade!

Especially the skin-friendly material on the side of the charging coil, which is very decompressive to play with, similar to stroking cats; but the entire magnetic power bank is too easy to get dust.

The first reason to choose Xiaomi magnetic power bank is also the most important reason for me personally: thin! The thickness of the magsafe external battery is about 11.2mm, while the thickness of the Xiaomi magnetic power bank is 12mm. In all fairness, the size of the magsafe external battery has not been given by the official. This value is a more unified statement after I have found a lot of content, while other categories of magnetic power banks: Lvlian’s 19mm, Romas’s 21.8mm, Anke’s 18mm, this is very important, especially for the Pro series mobile phone, it is too thick to hold at all.

Another reason is the use of both land and sea… Just kidding, it is a variety of charging modes. Magsafe’s battery input: 5-9V3A, capacity: 1460mAh, energy: 11.13Wh, battery pack voltage: 7.62V, total capacity is 2920mAh; many actual measurements are about 60%.

Do you see the two INs in the picture below? Xiaomi magnetic power bank supports C port input/output, 12W wired charging, 20W MAX wired input, and the magnetic suction port of IN2 can be charged through the charging seat.

The charging pile of the same material absorbs ash the same, and the charging seat itself is connected to the power supply with a single C port, which is different from a separate wireless charger.

After connecting, you can charge the power bank itself, or you can attach the mobile phone to it. However, because the magnetic power banks found so far do not have MFI certification, they are only 7.5W at most, which is not as easy to use as others.

I see a lot of people who evaluate, when testing the magnetic attraction stability without a mobile phone case, mobile phone naked punch people must not be much, right? Xiaomi’s magnetic attraction strength of about 10N, for iPhone without a shell stable, with a thick silicone shell can see the moving picture, no pressure.

Charge a 4352mAh iPhone 13PM with magnetic attraction, and charge 63 from 1%. The indicator light on the side flashes orange, indicating that the power bank is between 0-30%. I did not completely charge the power bank until it was turned off. The whole process is slightly hot and completely acceptable.

My family has a Xiaomi 80W air-cooled wireless charging seat. It is perfect to put one in the office. If the mobile phone has a high fast charging power and is in a temporary emergency, but the mobile phone is out of power, you can choose to charge it for a few minutes or go out directly with the power bank.

Lynk & Co 06 world premiere, creating luxury within reach of young people

The martial arts in the world are only fast and not broken.

Just a month after the launch of the Lynk & Co 05, Lynk & Co announced a new model, the Lynk & Co 06.

Less than three years after the first model was launched in 2017, this is the fifth brand-new model launched by Lynk & Co.

Unlike the industry’s traditional naming method of "the bigger the number, the higher the positioning of the model", the Lynk & Co 06 has the largest number, but it is currently the most entry-level model in the Lynk & Co family. The name of Lynk & Co has always been concise and easy to remember, and the hero is not in order. The Lynk & Co 06 is also a special existence in the Lynk & Co family.

On June 16, at the seven-star Atlantis hotel in Sanya, Lynk & Co 06 completed its world debut through a "deep-sea immersive" press conference. The on-site layout was very futuristic and technological. Just like the positioning of Lynk & Co 06 as "new urban function", the new car had a "mecha warrior" feel from the exterior to the interior.

In addition to the different naming methods, the Lynk & Co 06 also bears many Lynk & Co "first time" labels: this is the first Lynk & Co model built by the BMA-evo architecture, with many breakthroughs and innovations in design.

The team of designers from China and Europe told us that their inspiration came from the diverse architectural forms and digital social life. The original intention of the design was to create a car for the new era of the global urban population, bringing a "luxury from the start" car experience.

The new car is regarded as an advanced work of the Lynk & Co brand’s "urban opposition aesthetics". Although it is an entry-level model of the Lynk & Co brand so far, the Lynk & Co 06 is no less in design and configuration.

From the perspective of the appearance that young people value the most, 06 has the most personalized appearance of the entire family.

Breaking the inertial thinking, from "building a good-looking car" to "making a good-looking car more useful", Lynk & Co 06 has reached a higher level in design: both function and aesthetics, "the mech is in the model, and the function is in it" can be said to be the most appropriate description of its design sense.

Compared with other brothers in the Lynk & Co family, Lynk & Co 06 brings ten innovations in appearance and interior at one time:

New blue and orange contrasting colors, new "Z-shaped" waist line, light body suspended roof, hidden headlight design, two front grille options of "Urban Pulse" and "Digital Building", in addition, the induction welcome light matrix is also unique to Lynk & Co 06. No matter approaching the car from any angle, the welcome light matrix will automatically light up.

This design is in line with Lynk & Co’s consistent tenet and car philosophy: high-end but not cold, using seemingly cold technology to give the driver a warm care.

In the interior part, Lynk 06 adopts a new design officially called "energy fusion cabin", and the central control uses the energy crystal stone to cut the interior board for the first time. The irregular geometric shape carefully arranged is like an energy crystal, and through the advanced INS diaphragm light transmission technology, a highly technological energy crystal breathing ambient light is designed, which echoes the new mechanical dovetail energy crystal tail light. There are 72 color changes, presenting a psychedelic cyberpunk urban style; also adopts a new hand-held electronic file handle and aviation anti-reflection dashboard, which is full of technology.

In addition, the workmanship and materials of the Lynk & Co 06 overall model also maintain the consistently high level of the Lynk & Co brand.

In terms of size, Lynk & Co 06 has a length, width and height of 4340 x 1820 x 1625mm and 2640mm, providing excellent spatial performance. It has designed a lazy back row and up to 37 storage spaces.

Overall, regardless of the design, overall configuration, or manufacturing process, the Lynk & Co 06 is excellent. As the first car built for young consumers, it is a luxury that is accessible and affordable to young people.

After watching the debut press conference of the Lynk & Co 06, the editor girl born in 1994 said that she was a complete fan of the Lynk & Co 06 and was the first car of her life.

According to the official introduction, Lynk & Co 06 will accelerate the pace of listing after its debut, which is expected to be in August this year. After its launch, it will compete in the most mainstream compact market segment and is expected to become Lynk & Co’s most exciting model.

From 01 to 05, Lynk & Co has always given people a sense of individuality. Whether it is the first 01 that focuses on four-wheel drive performance, the high-energy coupe that focuses on trendy personality, or the sports performance, or the extreme sports 05 that has just been listed, every product of the Lynk & Co family gives people a feeling of "not taking the ordinary road".

In terms of sales performance, in May this year, the Lynk & Co brand achieved monthly sales of 12,950 vehicles, an increase of about 27.5% month-on-month and an increase of about 41% year-on-year. In terms of bicycles, the best historical performance is that it has achieved the highest monthly sales of 9,000 vehicles, but after its listing, it replaced the former’s "sales responsibility" position. The highest monthly sales volume exceeded 7,000 vehicles, and the current average monthly sales volume is basically maintained at about 6,000 vehicles.

Up to now, the cumulative sales volume of the Lynk & Co brand has exceeded 300,000 vehicles, which is also the fastest to reach the 300,000 level of China’s high-end.

As a brand new China, Lynk & Co’s current average price of bicycles is 156,000 yuan, and the end point price range is very stable, making it one of the highest premiums in China.

Throughout the history of the industry, new brands continue to emerge, and the competition has become increasingly intense. However, those who can really occupy the C-position on the stage are always those with strong brand power.

Lynk & Co is undoubtedly one of the most successful representatives of Chinese car companies’ brand growth, but based on the entire group’s planning and expectations for Lynk & Co, the burden on Lynk & Co’s shoulders is undoubtedly very difficult. At the beginning of this year, the holding group and group CEO made it clear that Lynk & Co’s future goal is in the order of millions. In the Chinese market, Lynk & Co has to compete head-on with mainstream joint venture car companies.

In order to become a millionaire, there must be more accessible mainstream models in the product matrix, and Lynk & Co 06 is here to shoulder this mission.

From the perspective of the market, regardless of the appearance or interior, Lynk & Co 06 is "very Lynk & Co", but the price and positioning are more affordable, specially designed for young consumers who like Lynk & Co’s design and brand tone, but the budget is not so high.

It has to be said that the move of Lynk & Co 06 has certain risks, opportunities and challenges coexist. Judging from the current exposure of the configuration of Lynk & Co 06, the price of Lynk & Co 06 is likely to be lower than the current average price of the whole Lynk & Co brand bicycle. It is still unknown whether this car will have a certain impact on Lynk & Co’s "high-end China" positioning and the high premium ability after three years of cultivation.

Kunshan: "Four chains power" to promote foreign trade to a new high

In the first 11 months of 2023, the total value of foreign trade import and export in Kunshan City, Jiangsu Province was 687 billion yuan, an increase of 8.8% year-on-year, accounting for 14.4% of the total value of import and export in Jiangsu Province. Among them, exports 459.78 billion yuan, an increase of 7.5% year-on-year, accounting for 15% of Jiangsu Province; imports 2272.2 billion yuan, an increase of 11.4% year-on-year, accounting for 13.3% of Jiangsu Province.

Since the beginning of this year, Kunshan has changed from passive to active and pressure to power, and foreign trade has shown a trend of steady progress and improvement in quality. In October, Kunshan’s monthly import and export crossed three billion steps, reaching 13 billion US dollars for the first time, driving the province’s foreign trade growth of 5.7 percentage points, and both imports and exports broke the historical monthly record. The latest released data shows that Kunshan’s import and export trade exceeded 10 billion US dollars for three consecutive months in September, October and November, and the monthly import and export value broke the historical record in September and October. Especially with the steady recovery of consumer electronics market demand, Kunshan’s foreign trade is expected to continue to improve and make Kunshan contributions to Jiangsu’s stabilizing the basic foreign trade market. When exploring the reasons for Kunshan’s foreign trade data to rise against the trend, the "industrial chain, value chain, innovation chain, service chain" and "four-chain force" have become the key to promoting Kunshan’s foreign trade to stabilize and improve.

Advance planning, deeply empower the "industrial chain"

Industry is the foundation of foreign trade, and strong industry makes strong trade. As a strong industrial city, the advantage of the industrial chain has always been Kunshan’s greatest advantage. In the field of electronic information industry alone, Kunshan has attracted more than 2,000 upstream and downstream enterprises to settle in, creating an electronic information industry chain with a total output value of over 600 billion yuan.

Kunshan has continuously consolidated the foundation and advantages of the two hundred billion-level industrial clusters of electronic information and equipment manufacturing, and strives to hedge the uncertainty of the external environment with the certainty of its own development, and create more possibilities. In the first half of the year, foreign trade faced greater pressure. Kunshan paid close attention to the demand orientation and development trends of traditional foreign trade industries such as electronic information manufacturing, and launched a number of assistance measures to help enterprises reduce costs and increase efficiency.

At the same time, Kunshan also plays the strong magnetic force of leading enterprises. The development of leading enterprises is related to the stability of foreign trade, and also affects the development of a large number of small and medium-sized enterprises. On the one hand, Kunshan vigorously implements the electronic information "consolidation" project and the equipment manufacturing "strong foundation" project, accelerates the deep integration of the digital economy and advanced manufacturing industry, actively plays the role of midstream enterprises linking the previous and the next, promotes the integration and innovation of the industrial chain and supply chain, and continuously enhances the global industrial chain. It has the voice over. On the other hand, Kunshan has also continued to release the "magnet" role of "chain owner" enterprises, extending investment tentacles, broadening investment channels, gathering a number of industrial chain and supply chain core enterprises such as SAIC, Tesla, BYD, Ningde Times, NIO, Dow Chemical, etc., and fully tapping the investment resources of upstream and downstream related enterprises. It is worth mentioning that Kunshan is also actively targeting new opportunities and new markets, promoting the transformation of traditional manufacturing to digital manufacturing, comprehensively optimizing the integrated layout of "core-cloud-network-end-chain", and promoting the intelligent transformation, digital upgrading, digital Product Research & Development, and intelligent equipment manufacturing of enterprises as a whole. "With hard belt and soft, soft and hard", we will accelerate the formation of a 100 billion-level universe industry innovation cluster.

Climb higher and break through, expand and extend the "value chain"

In the face of weak global consumer electronics demand, Kunshan encourages enterprises to optimize product structure, help enterprises to undertake high-end laptop orders, guide AUO Electronics to expand the import scale of high-end equipment and advanced technology, and guide enterprises to stabilize the global consumer electronics market share and continue to explore emerging markets.

Kunshan supports foreign trade enterprises to make good use of the two domestic and international markets and two resources, enhance the competitive advantage of technology, standards, brands, quality and service as the core, and achieve both domestic and foreign sales. Take the baby carriage king "Good Boy" as an example, the sales share of its "Evenflo" and "Cybex" brand child safety seats in North America and Europe are the first congeneric products, and the dominant position is gradually consolidating. "From January to October this year, our orders in the North American market increased by 12.4% year-on-year. We plan to continue to develop the North American and European markets next year." Wang Yong, general manager of the supply chain center of Good Boy Children’s Products Co., Ltd., said.

In addition, Kunshan also insists on leading development with major projects and competing for high-end resource elements globally. Vigorously carry out overseas investment promotion "Hundred Troupes War", from January to October, organized 32 investment promotion groups to Europe, Japan and South Korea and other countries and regions to carry out investment negotiations, successfully held 17 overseas investment promotion activities, visited more than 200 enterprises and institutions, and harvested more than 80 potential projects. Successfully held the 2023 Kunshan (Shenzhen) Investment Promotion Conference, signed 38 major projects with a total investment of 30.52 billion yuan. Vigorously attract a number of headquarters-type, leading-type, tax-source high-energy trading entities and "new quality productivity" projects, accelerate the signing and settlement of a number of key projects such as Coca-Cola, Dazheng Coffee, and Baoshi De, and through the "signing rate, completion rate, start-up rate, production rate, and production rate".

Regarding how to help new energy companies accelerate their "going overseas", Shi Yuhao, a customs officer from Kunshan Customs Inspection Division 1, shared his experience of helping: "We have established a’point-to-point ‘contact mechanism for key enterprises in our jurisdiction, and continue to provide technical services such as trade policy consultation, customs clearance and release of actual goods, to help enterprises seize opportunities to go overseas.

Take the initiative and accurately drive the "innovation chain"

Relying on the efficient vertically integrated industrial system and smooth bonded logistics channels of the Kunshan Comprehensive Bonded Zone, we will build an electronic product distribution center and expand the import of core components of the electronic information industry; continue to deepen the "bonded +" advantage, encourage enterprises to carry out bonded research and development business, guide processing trade enterprises to expand bonded inspection, bonded maintenance and other business models, and continuously enhance the resilience of the supply chain supply chain; link the "bonded area + professional market" function to build a digital commodity trading platform that integrates trading, settlement, clearing, finance, logistics and other functions.

Kunshan is also actively deploying hundreds of billions of coffee industry clusters, giving full play to the first-mover advantage of the import trade promotion innovation demonstration zone, promoting the development of the coffee industry towards clustering, diversification and high value-added fields, and actively creating new growth points for import trade. Kunshan has formed a chain around "one green bean" to "one cup of coffee", attracting more than 30 leading coffee companies such as Starbucks, Luckin, Yizheng, Zhongyuan of Vietnam, Louis Dreyfus of France, and Mitsui & Co., Ltd. of Japan to enter the chain. It has built an industrial ecosystem that integrates green bean trade, platform trading, R & D and roasting, brand sales, and coffee equipment, forming two major coffee industry characteristics: "whole industrial chain" and "internationalization". The city card of "China Coffee Silicon Valley" is about to emerge.

Based on the actual development and demand of the coffee industry, Kunshan uses "system + technology" two-wheel drive to tailor-made "three inspections and three releases" supervision mode for imported coffee inspection and quarantine. 90% of imported coffee goods have been "reported and inspected", and customs clearance efficiency has been significantly improved. In the first 11 months of this year, Kunshan achieved 31,200 tons of coffee beans imported, an increase of 213.6% year-on-year.

Kunshan is also grasping the strategic opportunity of the integrated development of the Yangtze River Delta region, giving full play to Kunshan’s geographical advantages, and building a "big channel" and "big platform" for opening up to the outside world in an all-round way. Optimize the connection between the Yangtze River Delta region and the ASEAN cargo trade platform, encourage bonded logistics enterprises to tap the trade potential under the premise of compliance with trade, and improve the efficiency of distribution and distribution. In the past six months, new imports and exports exceeded 9 billion yuan. Innovate to create a modern logistics center for the Yangtze River Delta International Airport, build a one-stop service platform for international air freight import and export, and use the innovative mode of direct access to the freight station to reduce the short-haul and multi-warehouse pickup links of trailers, achieve capacity integration, efficiency improvement, low-carbon emission reduction, seamlessly connect 111 airlines around the world, reach 1036 destinations around the world, smooth import and export freight channels, import and export speeds up by more than 10 hours and 5 hours respectively, cost reduction by more than 10%, and open up a new channel for air transportation of foreign trade enterprises.

Internally and externally, continuously optimize the "service chain"

"Kunshan service" is an important magic weapon for competing for orders, grasping projects and seeking development. Kunshan released the "Kunshan City Deepening" Kunruyi "Business Environment 2023 Innovation Action Plan" this year, and launched the "Investment and Business Protection Service Month" in advance; innovatively built a new government-enterprise communication platform "Kunruyi Enterprise Meeting Room", strengthened in-depth exchanges with enterprises, and stabilized development confidence; fully implemented the "28" new policies to promote the continuous recovery of the province’s economy, and introduced Kunshan City’s 45 policies and measures to promote the overall improvement of economic operation, 7 to stabilize foreign trade, and 12 to promote cross-border trade facilitation, and make greater efforts to promote the stability and improvement of the open economy; continue to build a development environment with "the lowest cost under the same conditions, the best service at the same cost, and the most market opportunities for the same service", and create the most attractive and competitive first choice for investment and entrepreneurship.

Taking supporting the development of the coffee industry as an example, Kunshan is neither a coffee origin nor a major consumer market. How can the coffee industry take root? In order to help Kunshan’s coffee industry connect with the world, Kunshan Customs implements a "customized" factor guarantee model. In response to the development needs of the coffee industry, a special class of coffee trade services has been established, and business experts have been selected to connect with coffee production enterprises, coordinate and solve the problems of enterprises in registration and filing, inspection and quarantine, and actual release. We provide "commissioner-style" services for the whole process of customs clearance. In this regard, Miao Shijun, head of Kunshan Real Gold Food Co., Ltd., said, "Under the guidance of Kunshan Customs, we quickly completed the filing of export food production enterprises, strengthened the quality control and safety management of key links in coffee roasting and processing, and effectively connected with the relevant laws and regulations of the target country. Further enhance the competitiveness of products in the international market. After the export road is completed, we will also rely on the advantages of Kunshan coffee’s entire industry chain to deepen cooperation with coffee leaders, so that Chinese coffee can enter the overseas market."

It is based on the continuous creation of a world-class environment that in the first three quarters of this year, 213 new foreign-funded projects were established in Kunshan, an increase of 6% year-on-year, and the actual use of foreign capital was 1.54 billion US dollars, an increase of 39.5% year-on-year. For Kunshan and enterprises, this is a fruitful result of two-way progress and mutual achievement.

Kunshan is a big foreign trade city and needs to have greater responsibility and action. Kunshan will take more hard-hitting and practical measures to fight for "order + market", focus on breaking through "project + business", continue to improve "service + policy", and firmly stabilize the basic foreign trade market.

Is the quality of BYD Qin good? What are its shortcomings? These 10 car owners tell you the answer!

BYD-Qin

Subsidized selling price: 14.99-22.51 million.

One disadvantage of the owner: the cab may have a little poor head space, and the co-driver and rear row are sufficient. The trunk lost some space because of the battery. Generally speaking, the trunk is usually enough if you don’t travel far. In addition, I personally think that although Qin is rich in configuration and hardware is in place, there is still some room for optimization in software functions. In addition, battery balance should be improved.

The second disadvantage of the owner: the engine noise is really a bit loud. When the battery is too low, the engine will automatically charge the battery. The speed is high and low, and the vibration is obvious. The engine noise is very loud, and the car will become very fleshy, without power, and the accelerator will start very slowly. However, this can be avoided. Try not to wait until the power is running out. It is recommended to turn on the hybrid when the power is lower than 50-30%. Of course, if it is coming home soon, it naturally doesn’t matter.

The owner’s three shortcomings: I really can’t say that there is no electricity to start, and the trunk is really small. If only the battery could be installed on the chassis like Tang, and the internal space is not very large. A 4.7-meter car should not have a small interior. I heard that the interior will be changed to a soft interior in 15 years. If only it could be changed for free.

Four disadvantages of the owner: the trunk has a small space because of the battery pack. The rear seat space is also cramped. But I am mainly in the driving position and feel comfortable. There is also charging, and there must be a convenient charging place. There is also a camera with low pixels and poor interior materials, which I hope to improve.

The owner’s five shortcomings: Qin’s shortcomings are that in the case of electricity, the noise is large, the vibration is obvious, and the low-speed power performance is very weak. At this time, Qin is not as good as an 80,000. So, don’t let your Qin have no electricity.

The owner’s six shortcomings: too comfortable steering, lack of road sense, more fragmented vibration of the chassis, power completely above the chassis limit, intense driving, ordinary workmanship, more complicated instruments and multimedia menus need a certain adaptation time, and the rear compartment is small.

Owner’s Seven Disadvantages: The disadvantage is that the LED bulb of the rear taillight is too big. I think the visual effect will be better if it is made into a light strip. Secondly, the trunk is small, and the sound insulation of the whole vehicle needs to be strengthened. If the sound insulation is good, it will be comfortable to drive. In hybrid mode, the sound insulation effect of the engine is not satisfactory. Others, by the way, the low beam has a lens, but why not a xenon lamp? At least it’s a 200,000 car. Haha, the position of the position light connected with the daytime running light has to be turned on manually every time during the day. I think this loses the meaning of the daytime running light, and it should be turned on automatically. When it is not needed, it is only reasonable. The indoor atmosphere light works well, but it is so big except for the lack of the welcome pedal. The first impression of opening the door is very important. The shiny BYD or Qin’s aluminum pedal should be much more upscale than a few plastic plates. The center console doesn’t have a one-button direct access to the main menu button. You have to press the steering wheel menu button three times to jump, which is sometimes not very convenient. Having said that, it’s not that the car is black, but I just hope BYD will do better and more perfect.

Owner’s Eight Disadvantages: On the day of delivery, the new car just went down a few meters, and the dashboard popped up. Please check the power system. The phenomenon is that you can’t switch EV mode, but you can only use HEV mode to start the vehicle. I thought it would be fine if the battery is not enough to charge, but the result is that you can’t charge. Fortunately, the engineer of Biya was called to check it with a detector, and the function was normal after eliminating two fault codes, saying that the system sometimes misreported. Although Qin’s configuration is very high and excellent in all aspects, due to a lot of electronic configurations, I think there is still room for optimization in the controller program. I believe that this is only the prelude to the great development of new energy, and it will present us with more perfect products and services.

Owner’s 9 Disadvantages: Qin’s interior materials and workmanship need to be strengthened. Compared with my previous car, which is also the interior of the domestic brand, it really needs to be improved. There is also a battery in the trunk, so the space in the trunk is limited. There is no way to do this.

Ten shortcomings of the owner: the trunk space is slightly smaller, but the household can make do! Hybrid fuel consumption is average, and the engine sound is slightly louder. I wonder if pure electricity is too quiet! The noise of the rear wheel passing through the gravel road is too loud. Contact to increase the sound insulation cotton of the rear wheel compartment! The black mirror of the central control door handle is too easy to scratch, and I have only mentioned it for half a month, which is terrible!

In 2030, a network of 300 satellites will be in operation — decoding the ultra-low orbit and remote integration satellite constellation

  Xinhua News Agency, Wuhan, July 12 Question: In 2030, a network of 300 stars will be in operation – decoding the ultra-low orbit and remote integrated satellite constellation

  Xinhua News Agency reporters Hu Zhe, Tan Yuanbin, Song Chen

  Low-orbit constellation construction is an important part of national strategic science and technology, and is of great significance for promoting economic development. With the development of society and the improvement of people’s living standards, the demand for satellite communication, navigation, remote sensing and other functions continues to increase. Low-orbit constellation construction can provide more accurate, real-time and efficient services to meet the needs of all parties.

  On July 12, at the 9th China (International) Commercial Aerospace Summit Forum opened in Wuhan, Hubei Province, China Aerospace Science and Industry Corporation announced the official launch of the ultra-low orbit and remote satellite constellation, and the first satellite is planned to be launched in December. What is the background of the construction of this satellite constellation? What are the main features?

  Open up a new track for the progress of aerospace science and technology

  Ultra-low orbit refers to an orbit with an orbit altitude of less than 300 kilometers, which reduces the satellite from the traditional low-Earth orbit to less than 300 kilometers, so that its "remote sensing" to the earth becomes "near-end", so that it has the advantages of low payload cost, small communication delay, and miniaturization of user end points.

  Li Yanbin, deputy general manager of the general department of space engineering of China Aerospace Science and Industry Corporation, said that by building an open distributed intelligent networked ultra-low orbit space foundation base, by carrying different loads, supplemented by advanced on-board intelligent processing, satellite terminal direct connection, and inter-satellite communication technology, space information can be quickly and accurately obtained, serving the urgent needs of governments, enterprises, and even individuals for higher precision, high timeliness, and high reliability of space decision-making information, which can stimulate the huge potential of the commercial remote sensing market, open up a new track for the progress of aerospace science and technology, and shape the development of the space information industry.

  Unlike traditional orbits, ultra-low orbit has a complex dynamic environment, with rarefied atmospheric drag and atomic oxygen flux increasing with a nearly logarithmic law as the orbit decreases. To maintain long-term stable and reliable operation of satellites, it is necessary to offset the rapid decay of satellite orbits due to higher atmospheric drag. Although long-term operation in ultra-low orbit requires many technical challenges, the investment value is huge. The United States, Japan and Europe have all launched relevant commercial or scientific sounding activities.

  See better, faster, understand better

  The ultra-low orbit and remote integrated satellite constellation aims to develop a large-scale real-time intelligent remote sensing service system in ultra-low orbit, give full play to the natural advantages of proximity, low delay and small road loss, and create an ultra-low orbit and remote integrated satellite constellation and its application system with "small but fine", "fast and smart" and "many and cheap" as differentiated characteristics. It incubates a new domain and new quality space infrastructure for direct connection to user sensing, transmission and calculation, and establishes a new digital economy format for satellite direct connection to mass users.

  Zhang Nan, the chief designer of the ultra-low orbit remote integrated satellite constellation, introduced that the ultra-low orbit remote integrated satellite constellation mainly has the following characteristics: first, it can see more clearly, and the spatial resolution will reach 0.5 meters; second, it can see faster, and the spatial information will reach the user within 15 minutes; third, it can be seen more clearly. Through intelligent processing on the satellite, direct connection to the star terminal, and inter-satellite communication, the ground centralized processing data link is omitted, and the spatial information can be directly reached to the user end point. At the same time, the cost of a single satellite of the ultra-low orbit remote integrated satellite constellation will be lower, and the optical load weight and cost will be reduced by 50% under the same resolution.

  Facing the future, the construction of the ultra-low orbit remote integrated satellite constellation will be implemented step by step, including three stages:

  In the technical and business verification stage, complete the key technology verification of ultra-low orbit satellites, carry out on-orbit technical tests and business verification; in 2024, complete the launch of a 9-star business verification star cluster; in 2025, build a real-time remote sensing business application demonstration system to provide 1-day service response capability.

  In the stage of large-scale networking, it will be widely used in the industry to form large-scale networking and achieve half-hour response capability. It is planned to complete the operation of 300 satellite networking in 2030, providing a visible light, synthetic aperture radar, hyperspectral, and infrared multi-type OurHours remote sensing service system to form a global 15-minute response capability.

  In the integrated development stage, complete the comprehensive construction of the business system, achieve instant business response capabilities within 10 minutes worldwide, and provide complete instant perception services.

  Satellites are becoming more "intelligent"

  The construction of the ultra-low-orbit remote satellite constellation not only shows our country’s latest strength in the aerospace field, but also breaks through a number of key technologies, providing more opportunities and challenges. According to reports, the satellite will achieve multi-satellite coordination through inter-satellite links, such as the first satellite receives user requests, the second satellite shoots the required information, and the third satellite completes intelligent processing. At the same time, the satellite will also become more "intelligent", capable of real-time processing and intelligent recognition of image data in orbit, and fast distribution of results through inter-satellite links.

  In the face of the needs of the field of emergency rescue, the ultra-low orbit remote integrated satellite constellation can provide high-efficiency disaster information, which can provide effective data and capability support for emergency rescue, fire monitoring, disaster prevention and mitigation. The satellite application service platform provides users with normalized disaster monitoring and early warning. After an emergency incident occurs, inter-satellite transmission and on-board intelligent processing can efficiently shoot and extract key information, relying on the network to directly transmit to the vehicle or portable end point, within 15 minutes for the first-line disposal unit and front-line command agencies Provide high-efficiency disaster area scene images, efficiently support emergency rescue and auxiliary decision-making.

  With such a huge constellation construction, how to make a profit is also a topic of concern to everyone. Li Yanbin introduced that on the one hand, commercial profits can be obtained by selling satellites and user end point products (including software), spatial data products and value-added services; on the other hand, by building an ultra-low orbit space base to create a new quality and new domain industrial ecology, and collect payloads for the society to achieve mutual benefit and win-win results.

Huawei Ascend P7 detailed review: the appearance and workmanship are improved, the running score is average, and the photo effect is good

  As Huawei’s most successful last yearSmartphoneProduct, Ascend P6 has successfully broken through 6 million in global shipments, which has also doubled Huawei’s confidence in the P series, so this year’s follow-up product P7 has naturally become one of Huawei’s most important products. Yesterday’s press conference in Paris, France, it can be seen that Huawei is eager for the European market, and the importance of P7 is evident.

  HUAWEI P7The biggest feature comes from the upgrade of hardware. How the new HiSilicon 910T processor performs has become a concern for many people. And before the press conference, I got this Huawei P7 phone. For many netizens’ concerns, I will answer them one by one through the evaluation.

Appearance: Details improved, workmanship improved

  More than half of the success of the P6 is due to the excellent design of the phone, and Huawei naturally wants to extend the design essence of the P6 to the P7. So when I first got the phone, in addition to the feeling of getting started and the material change, I didn’t find any more differences between the P7 and the previous one.

  However, after careful study, I found that there are still many improved designs between the P7 and P6. First of all, the material of the mobile phone, the back case of the P7 is made of glass, instead of the metal brushed material of the P6. In terms of feel, the glass surface of the palm feels better, but glass is easier to use as a fingerprint collector than brushed metal, which is a double-edged sword.

How did the Milky Way look like "potato chips"?

  Einstein once said: "The most incomprehensible thing in the universe is that the universe is comprehensible!" Since ancient times, the beautiful and vast Milky Way in the night sky has triggered countless imaginations and brave explorations, from the Three Kingdoms period "Xinghan is brilliant, like out of it" to the Song Dynasty "The Milky Way is like three thousand songs, and the bathing mallard flying heron is green"… It has pinned the expectations and yearning of generations of people for the Milky Way.

  "Upturned" Milky Way

  With the advance of observation technology, astronomers can gaze at the galaxy they dream of, and people’s understanding of the true face of the Milky Way is constantly improving. At present, the Milky Way we know is a galaxy about 200,000 light-years in diameter, with a box-shaped "nuclear ball" in the middle, surrounded by a flat "silver disc", and a huge "silver halo" looming above and below the silver disc.

  About 70 years ago, scientists have known that the Milky Way is "warped". The edge region on one side is curved "up" from the plane of the Milky Way to the north, and the other side is curved "down". From a distance, it looks like the potato chips we usually eat. That is to say, when we look at the Milky Way from the side, we can see that the Milky Way has a S-shaped "body" that is convex and backward.

  However, for a long time, due to the limitations of observation conditions, scientists could not vividly present the "potato chip-like" structure of the Milky Way in front of us with real and accurate star observation data.

How did the Milky Way look like "potato chips"?

  In 2019, scientists in our country, Chen Xiaodian and others, first outlined the three-dimensional spatial distribution characteristics of the warping structure of the Milky Way through star counting, which provided direct observational evidence for humans to truly observe the structure of the Milky Way’s "potato chips".

  The Milky Way, as a typical disk galaxy in the vast universe, has both universality and particularity. Why is the Milky Way so "warped"? What is the secret to maintaining an S-shaped body? For a long time, there have been various opinions and assumptions in the astronomical community, and it has become a hot topic of discussion among international astronomers.

How did the Milky Way look like "potato chips"?

  "Upward" foresight

  Some people think that the interaction between the Milky Way’s halo and the disk can produce a "warp structure"; some people think that gas falling into the Milky Way disk can give rise to a "warp structure" of the Milky Way disk; some people think that the Magellanic Cloud at the doorstep of the Milky Way or the collision of the neighboring Sagittarius galaxy is also a possibility; there is even a view that the Milky Way’s magnetic field also plays an important role in the formation of the "potato chip" structure and so on. For a long time, there have been new breakthroughs in the research on the source of warping, but it is difficult to reach a consensus.

  Scientific theories need to be confirmed step by step by the measured data, and the ESA Gaia Survey presents an opportunity. Because the Gaia satellite can help us make unprecedented measurements of the three-dimensional speed of stars, astronomers use this new data to study and discuss warping increasingly.

  In order to make it easier to understand, astrophysicists start from the macroscopic direction and simply classify the formation mechanism of the "potato chip" shape of the Milky Way disk into two categories:

  The first type of reason is due to external attraction and influence, due to the attractive force process between the Milky Way disk and the surrounding non-luminous matter or the outer dwarf galaxy. Simply put, our Milky Way disk is like a star full of "idol baggage", attracting each other with the surrounding fans, and the "concave shape" has concave such a graceful figure.

  The second type is considered to be a long-term evolution process that is not dominated by the interaction of attractive forces, and is simply called a non-attractive force process. For example, the influence of gas falling around the silver disk or magnetic field action caused the silver disk to be so "warped".

  New knowledge of "warping"

  If the second cause causes the "warp structure" of the galaxy, it is characterized by the bending strength of the young star family on the silver disk than that of the old star family. This is because if the non-attractive force process dominates, then the mechanism mainly acts on gas or young stars, and the old star has enough time to digest the influence of the external non-attractive force process on it, thus reflecting the distribution of bending strength of different stellar families that can be detected by humans.

  Although we can use the massive data of the Gaia satellite to explore this, it currently measures the velocity of the star line of sight in a small range, and it cannot provide ideal star chemical information, age information, etc. Even the distance measurement of stars farther away from the galactic disk is not accurate enough.

  Fortunately, our country’s major scientific and technological infrastructure, the Guo Shoujing Telescope (LAMOST), can better solve these shortcomings, and also provide us with an excellent opportunity to explore the origin of the galactic "warp" structure and inquire about its past, present and historical context.

How did the Milky Way look like "potato chips"?

  The international research team led by Wang Haifeng, a special young researcher of LAMOST, based on the rich information of stellar parameters in the LAMOST sky survey spectral data, cleverly constructed a probability distribution function, and traced the characteristics of the silver plate "potato chips" from a novel perspective.

  They found that the bending strength of the "potato chip" form of the Milky Way disk decreases with the age of the star, and such a "warped" body can be maintained for a long time, but it is an unstable state. Based on scientific analysis, they reliably found evidence that the warped structure originated from a non-attractive force process represented by gas falling. Therefore, based on the advantages of LAMOST, the researchers found that the "warped" of the Milky Way disk is actually a structure that originated from a non-attractive force physical process and has been in an unstable state for a long time.

How did the Milky Way look like "potato chips"?

Evolution of galactic warping intensity, which decreases significantly with age, supports the conclusion that warping originates from non-attractive force processes

  This discovery advances our understanding of the origin of warping and takes a whole new step towards understanding the warping and origin of the Milky Way’s disk.

  In the future, the research team will make more efforts in terms of data and physics, gradually realizing the ideal of obtaining a complete physical image of the Milky Way, and then opening one mysterious and unknown door after another to restore the evolutionary history of the Milky Way and even the nearby universe.

Foreign experts show you the achievement exhibition: an interactive experience that is refreshing

  CCTV News:The "Five Years of Forging Forward" exhibition showcasing China’s great achievements in the past five years was held at the Beijing Exhibition Center from September 26 to November 26. The exhibition attracted many visitors and showcased China’s many achievements in the fields of science and technology, medical care, culture and anti-corruption in the past five years.

  Walking into the exhibition hall, we can see many successful examples of new rural construction. After the Chinese government has increased infrastructure building and taken various poverty alleviation measures, local people’s living standards have improved and the economy has become prosperous. In addition, through the exhibition, we can also learn about the rapid progress of China’s science and technology field, such as the large fire extinguishing/water rescue AG600 amphibious aircraft, as well as unmanned cars and artificial intelligence robots. China’s self-developed Beidou satellite navigation system (BDS) is impressive, and the demonstration of intelligent health service robots and medical examination systems and 3D printers is also refreshing.

  An interactive experience that allows you to experience the power of the Beidou satellite navigation system 

  Beidou satellite navigation system is one of the most advanced satellite navigation systems in the world. The exhibition area provides interactive experience equipment such as flying emulator and car driving emulator equipped with Beidou satellite navigation system, which allows visitors to experience the clarity and accuracy of Beidou system firsthand. Visitors can also understand the super scale and super functions of Beidou system through the Beidou system model and brief introduction in the exhibition area.

  As a mature satellite navigation system, the Beidou system has been widely used. As early as the 2008 Wenchuan earthquake disaster, the Beidou-1 system has played an important role in disaster relief. Affected by the earthquake, local communications, electricity and transportation were almost completely destroyed, and the disaster area was completely lost from the outside world. The Beidou Central Control System and the Beidou Navigation Emergency Team established to deal with the disaster have provided reliable and real-time large amounts of data for rescue operations. In addition, since 2010, the border guards in Yunnan Province have been fully equipped with the Beidou-1 positioning system, which is used to strengthen border patrols and combat border crimes.

  According to the plan, by 2020, China will complete the network of 35 Beidou-3 satellites, building a Beidou global system that rivals and surpasses GPS in some indicators, and can provide services to the world. At that time, Beidou will achieve even greater achievements. Of course, it is believed that there will also be rich profits. According to reports, the annual turnover of the Beidou system has reached 31.50 billion US dollars.

  "Intelligent Health Service Robot" invites you to take a quick physical examination

  Another highlight of the exhibition is the "intelligent health service robot" that is already being used in remote areas of China. Visitors can experience a free quick medical examination on the spot. Visitors simply put their ID card on the robot’s scanner, and it can identify your personal information. Then the person in need of the medical examination stands on a scale, reaches his left arm into a blood pressure meter, and holds another test instrument in his left hand. The robot can quickly analyze some basic indicators to detect whether the person has a problem. The test results can also be transmitted electronically to the designated hospital.

  The device was developed and produced by a company in Xianyang, Shaanxi Province, and has been in use for more than a year. It is mainly used in Qinghai and Gansu provinces in northwest China. It is especially suitable for the elderly who live in rural areas and are not very convenient to go to large hospitals for medical examinations. With a large rural population and many still living in areas with inconvenient transportation, this kind of medical examination method that can provide door-to-door service, coupled with reasonable price, can indeed bring convenience to villagers in need, so there should be a very broad market prospect.

  3D printing technology is refreshing

  Another popular exhibit is a 3D printer. The staff in the exhibition area can print beautifully designed and complex three-dimensional patterns on the spot with slurry made from mashed potatoes. Although the exhibition area demonstrates only the "small tricks" in 3D printing, we can also see the advantages and future trends of 3D printing. China, one of the world’s largest manufacturing countries, has enthusiastically embraced the technology of 3D printing. Sales of 3D printers in China have increased year by year in the past few years, and sales are expected to exceed 20,000 units by 2020.

  While the industry is still in its infancy in China, companies across the country are already using 3D printing in innovative ways. In early 2017, Blu-ray Innox in Chengdu, Sichuan, used 3D bioprinting technology to successfully print blood vessels and transplant them into rhesus monkeys. The success of this test is an important breakthrough in 3D printing medicine and the first step in the history of 3D printing of human organs. (Author: Colin Robinson, British, CCTV foreign expert)
