　　People’s Daily Online, Beijing, December 9 (Reporter Yang Yubolo) On December 9, 2022, the world’s first domestic C919 aircraft numbered B-919A was officially delivered to China Eastern Airlines.

　　According to the introduction of China Meteorological Bureau, in the face of blank fields and technology monopoly, meteorologists have repeatedly broken technical barriers and constantly explored weather support technology for flight test, thus escorting the journey of airworthiness and evidence collection of domestic large aircraft.

　　On May 5, 2017, with the roar of the engine, the domestic large plane C919 took off at Shanghai Pudong International Airport and rushed into the sky. This is the successful first flight of domestic large aircraft C919.

　　According to Li Boping, the head of the flight test meteorological support team of Shanghai Meteorological Bureau, the morning of the first flight was overcast, and the flight test meteorological support team, which was jointly composed of the meteorological department and Commercial Aircraft Corporation of China (hereinafter referred to as "Comac"), accurately captured the "good weather" window of two hours under adverse weather conditions, and successfully ensured the C919 to safely perform its first flight mission.

　　The success of meteorological support for the first flight is only the beginning. Li Boping said that the first flight of a new aircraft needs harsh "good weather", while the flight test around airworthiness certification needs to find "bad weather" under extreme meteorological conditions. Before officially entering the market, the aircraft must pass a series of test flights and obtain airworthiness certificates. Testing and inspection in "bad weather" such as crosswind, high temperature, high humidity, cold and natural icing are all important tests in the airworthiness certification of aircraft, and targeted meteorological support services are urgently needed.

　　Due to the late start of China’s civil aircraft business, excessive dependence on foreign technology has made it very passive for domestic large aircraft to obtain evidence, so it is urgent to "localize" the weather support service for test flight. Since 2014, focusing on the flight test demand of domestic large aircraft, Shanghai Meteorological Department has stepped forward, actively docked Comac and China Flight Test Research Institute, established the first professional flight test meteorological service support team in China, and started the dream-seeking journey of "localization" of flight test meteorological support.

　　In the past five years, the flight test meteorological support team has continuously broken through the "stuck neck" technology, and provided several flight test meteorological support services for ARJ21 and C919 models, covering flight test subjects such as natural icing, strong crosswind, high temperature, high temperature and humidity, and extreme cold, as well as routine flight test activities such as first flight and transition, and accurately monitoring and accurately predicting key weather safety conditions such as visibility, strong wind, clouds, precipitation and bumps.

　　Natural icing flight test is one of the most difficult subjects, which requires extremely strict requirements on the liquid water content of clouds, the diameter of water droplets in clouds and the temperature of surrounding air. Once, in order to complete the test flight of natural icing, the ARJ-21 plane searched in Urumqi for four years without success, and finally went to Wan Li in North America to search for ice.

　　"Although the information and methods available for reference in China are almost blank, we always believe that clouds that meet the conditions of natural icing flight test can be found in China!" According to Li Baiping’s memory, at first, the team started with a large number of domestic and foreign natural icing forecasting methods and learned the forecasting algorithm of foreign aircraft icing meteorological conditions. The method is available, but it is "acclimatized" when applied to domestic flight test.

　　It is urgent to verify and optimize the algorithm. In order to obtain a large number of observation data and repeatedly test the algorithm, the flight test meteorological support team took the initiative to enter the icing area to test the flight. Since 2016, it has carried out comprehensive aircraft icing detection tests in Anqing, Anhui, Yichang, Hubei and Shaanxi. At the beginning of 2021, the team conducted long-term tracking and forecasting for four key natural icing target areas in China, sampled cloud physical parameters such as supercooled water and icing, and successfully collected a large number of experimental data and materials, which laid the foundation for preparing for the natural icing test flight of C919 large passenger aircraft.

　　The flight test meteorological support team carefully compared the prediction results and test data one by one based on the algorithm, and based on the technical advantages of China Meteorological Bureau’s Shanghai numerical forecast model system, developed a new method for forecasting the natural icing potential for large aircraft flight test, gradually formed an autonomous and controllable meteorological service capability for the whole process of aircraft icing flight test, and finally effectively reduced the probability of empty reports.

　　The breakthrough of technical bottleneck and the autonomy of support ability have given the flight test meteorological support team confidence and laid a solid foundation for the ultimate success of natural icing flight test.

　　On February 17th this year, C919 completed the natural icing test flight over Yanliang, Shaanxi Province, achieving a "zero breakthrough" in completing the natural icing test flight of aircraft in China according to airworthiness standards, and taking an important step towards airworthiness forensics.

　　The success of this test flight is the result of the continuous accumulation of countless people over the years, and there is also a strong support provided by the meteorological service process of aircraft icing test flight combining "trend pre-diagnosis" and "proximity diagnosis".

　　As early as mid-January, the flight test meteorological support team started the "trend pre-diagnosis", obtained a series of natural icing forecast products in the short to medium term based on the numerical forecast system, and gave the forecast opinion that "from January 20 to 28, Shaanxi will experience a large-scale rain and snow weather process" one week in advance, capturing a precious meteorological "window". Three days before the test flight, the team provided a more detailed weather forecast to provide decision-making basis for large aircraft to apply for test flight airspace and test flight time.

　　The weather process is always evolving. When the time of flight test approaches, "proximity diagnosis" will be started immediately. On the day of the test flight, everyone held their breath. The test flight support team closely tracked the weather changes by using multi-source observation data such as satellite cloud images, weather radar and sounding station data, adjusted the forecast conclusions in time, and kept close communication with the test flight site to guide the aircraft into the frozen clouds in time.

　　The results show that the predicted icing condition is basically consistent with the actual detection.

　　With the concerted efforts of all parties, as of February 17, the flight test support team had carried out a total of 5 flight tests and crossed the clouds 29 times, successfully capturing the icing weather that met the requirements of the regulations.

Emil Wakin Chau is a singer who has attracted much attention and love. He once sang many classic songs, such as Friends, She said, Love Transfer and so on, which were deeply loved by the audience. However, recent media reports that Emil Wakin Chau has disappeared for half a year have aroused widespread concern and speculation. Among them, a popular view is that "disappearance" is related to "derailment" before Emil Wakin Chau. So, is there really a relationship between Emil Wakin Chau’s "disappearance" and "derailment"?

First of all, we need to review this "derailment" incident. It is reported that in November, 2019, Emil Wakin Chau was reported to have a bad relationship with her female assistant, proper relationship. This incident caused a great shock and discussion at that time, and Emil Wakin Chau later publicly apologized and announced that he would suspend his performing arts activities for a period of time. However, in the following months, Emil Wakin Chau did not appear in public view, which made many fans feel worried and puzzled.

So, is there a relationship between Emil Wakin Chau’s "disappearance" and "derailment"? Judging from the current situation, this view has certain rationality. First of all, Emil Wakin Chau’s previous "derailment" has damaged his reputation and image to a certain extent, which will have an impact on his acting career and personal life. Secondly, after this incident, Emil Wakin Chau also expressed his willingness to suspend his performing arts activities, which also shows that his influence and understanding on this matter are very clear.

However, we can’t simply generalize and summarize the disappearance of Emil Wakin Chau. After all, a person’s working and living conditions are very complicated and diverse, and it is impossible to react too violently just because of one incident. In addition, there is no clear evidence to prove that Emil Wakin Chau’s "disappearance" is directly related to "derailment", which also needs our continuous attention and observation.

In fact, the relationship between Emil Wakin Chau’s "disappearance" and "derailment" is not the most important issue. More importantly, we should respect Emil Wakin Chau’s personal privacy and emotional state, and don’t speculate and attack him for no reason. After all, a person’s privacy is his own right, and we have no reason or right to interfere and criticize. At the same time, we should also respect and appreciate Emil Wakin Chau’s acting career and works. After all, the musical and emotional value he brought to the audience cannot be ignored.

On April 20th, 2023, Emil Wakin Chau had disappeared for half a year. For this news, outside speculation and discussion have never stopped. Among them, a popular view is that Emil Wakin Chau’s "disappearance" is related to his previous "derailment". So, is Emil Wakin Chau’s "disappearance" really due to "derailment"? This paper will discuss this issue from multiple angles by combining relevant information and viewpoints.

First of all, we need to review this "derailment" incident. In November, 2019, it was reported that Emil Wakin Chau was not in proper relationship with her female assistant. This incident caused a great shock and discussion at that time, and Emil Wakin Chau later publicly apologized and announced that he would suspend his performing arts activities for a period of time. However, in the following months, Emil Wakin Chau did not appear in public view, which made many fans feel worried and puzzled.

So, is there a relationship between Emil Wakin Chau’s "disappearance" and "derailment"? Judging from the current situation, this view has certain rationality. First of all, Emil Wakin Chau’s previous "derailment" has damaged his reputation and image to a certain extent, which will have an impact on his acting career and personal life. Secondly, after this incident, Emil Wakin Chau also expressed his willingness to suspend his performing arts activities, which also shows that his influence and understanding on this matter are very clear.

However, we can’t simply generalize and summarize the disappearance of Emil Wakin Chau. After all, a person’s working and living conditions are very complicated and diverse, and it is impossible to react too violently just because of one incident. In addition, there is no clear evidence to prove that Emil Wakin Chau’s "disappearance" is directly related to "derailment", which also needs our continuous attention and observation.

In addition, Emil Wakin Chau’s "disappearance" may also involve other factors. For example, he is a relatively low-key person, unwilling to expose his private life and emotional state too much. Before that, he also expressed his boredom with entertainment life, hoping to live a more free and simple life. Therefore, Emil Wakin Chau’s "disappearance" may also be due to personal choice and pursuit.

In addition, Emil Wakin Chau’s "disappearance" has a certain relationship with his music career. In fact, Emil Wakin Chau’s performing arts activities had been gradually reduced and no new works had been released before the "derailment" in 2019. This has also led to a decline in his influence and popularity in the entertainment circle. Therefore, Emil Wakin Chau’s "disappearance" may also be related to his pursuit of music. He may be thinking about how to return to music itself better, instead of wasting his energy on superficial hype and exposure.

To sum up, the relationship between Emil Wakin Chau’s "disappearance" and "derailment" is reasonable to a certain extent, but we can’t simply summarize it. On this issue, we should respect Emil Wakin Chau’s personal privacy and emotional state, and at the same time maintain respect and appreciation for his acting career and works. Only in this way can we better understand and solve this problem, and at the same time protect and promote social justice and morality.

　　Fifty-five brands were removed from the list of Chinese time-honored brands, and 73 brands were required to be rectified within six months … … Recently, the Ministry of Commerce and relevant departments announced the results of the review of Chinese time-honored brands, which attracted the attention of the outside world.

　　Many Chinese time-honored brands that have been delisted this time are brands that consumers have been familiar with, such as Daoxiang Village in Tianjin, Guanshengyuan in Chongqing and Xihu Brand in Shanghai. Why are these old brands taken off the "golden signboard"?

　　accept a transfer-listed player

　　The removal of 55 brands from the list of Chinese time-honored brands this time is the result of the review of Chinese time-honored brands announced by the Ministry of Commerce in conjunction with relevant departments after self-examination, local initial verification, expert review and social publicity. In addition to the above-mentioned 55 brands that were delisted, the five departments also rectified 73 brands with poor management and declining performance within a time limit of six months.

　　shop sign

　　The store motto is catchy, the store rules are unforgettable, and the products are inexpensive … … Time-honored brand is a "golden signboard" bred in the history of China’s industrial and commercial development, which has high economic value and rich cultural value. At present, 1,000 standardized and well-developed brands still remain.

　　/China Time-honored Brand/

　　The Ministry of Commerce, the General Administration of Market Supervision and other departments have formulated the Administrative Measures for the Demonstration and Creation of Chinese Time-honored Brands, and put forward four basic conditions for the demonstration and creation of Chinese time-honored brands:

　　 The brand has been established for more than 50 years (inclusive)

　　 With Chinese national characteristics and distinctive regional cultural characteristics.

　　 Providing products, skills or services with high economic value and cultural value for residents’ lives.

　　 It is representative, leading and exemplary in its industry or field, and has been widely recognized and praised by the society.

　　The new dilemma of time-honored brands

　　Poor management for a long time, bankruptcy, cancellation, closure, or loss of ownership and use right of registered trademarks of time-honored brands are the main reasons for these brands being delisted.

　　The survival of the fittest and the elimination of the old brands cannot be "old" forever.

　　The reporter noticed that many of the old brands that have been removed from the list are "golden signboards" in the minds of consumers, and even the famous "Daoxiang Village" is impressively listed.

　　Among the delisted enterprises, Tianjin Daoxiang Village has attracted much attention because it has the same name as Beijing Daoxiang Village and Suzhou Daoxiang Village. The brand of Daoxiang Village in Tianjin has a long history, which can be traced back to the Qing Dynasty. However, due to the conflict with the trademark of Daoxiang Village in Beijing, there is only one "rice ear" graphic trademark at present.

　　Daoxiang Village in Beijing, founded in 1895, is the first company in Beijing to produce and operate Nanwei food, and now it has developed into a large enterprise with nearly 3,000 employees. In addition to being recognized as "China’s Time-honored Brand", Beijing Daoxiang Village also won the "China Famous Trademark". From this point of view, Tianjin Daoxiang Village and Beijing Daoxiang Village are far from each other in terms of company scale and market reputation except for the same name.

　　The reporter learned that Tianjin Daoxiangcun Food Co., Ltd. is currently wholly owned by Tianjin Huaxu Trade Food Group Co., Ltd., a state-owned enterprise in Heping District, Tianjin. A person in charge of the company told the reporter that due to multiple reasons such as company restructuring and merger, Tianjin Daoxiang Village no longer produces food and cakes, and the restaurant has been closed for a while. At present, the company only relies on part of the leasing business to maintain.

　　"It’s a pity that we failed to pass the review of China Time-honored Brand this time, because the company has indeed stopped producing related products, but the company has not completely given up ‘ Daoxiang Village ’ The brand will also take the opportunity to revitalize the old brand. " The person in charge said.

　　Some of the difficulties are not well managed, and they have gone bankrupt, cancelled or closed down.

　　Among the 55 brands that have been removed from the list of Chinese time-honored brands, there are 17 in Shanghai. The reporter learned that the "West Lake Brand" of Shanghai West Lake Hotel Co., Ltd., which was removed from the list, has not been reopened for several years after the demolition and transformation, and it is actually no longer operating; "Qian Wanlong" soy sauce has actually been discontinued; There are also historical issues such as intellectual property rights, which lead to non-compliance with the declaration.

　　"Pisces" brand is the only "old brand" in Henan that has been removed from the list. The reporter called the parent company of "Pisces" brand — — Kaifeng Tianfeng Noodle Industry Co., Ltd., after the other party learned the reporter’s intention to go to electricity, said that the company had gone bankrupt. "Almost all the responsible persons have left their jobs, so I’ll ask who else can be interviewed." Then there was no reply.

　　According to public information, Tianfengmian filed for bankruptcy in 2019 and was listed as an executor of dishonesty for three times.

　　The reporter tried to contact more than 20 brand-owned enterprises that have been removed from the list of Chinese time-honored brands. Except for some public telephones that were not answered or displayed as empty numbers, most enterprises that were able to connect refused to be interviewed. And a few companies that are willing to be interviewed have different reasons for the brand being "delisted".

　　The person in charge of Wu Jiabao Xing Bacon Products Co., Ltd., Yaodu District, Linfen City told the reporter that "I quit a few years ago"; Anhui Shouchuntang Pharmacy said that it is currently changing stores and will continue to work when it finds a new location; The person in charge of Taigu Tongbao vinegar industry said that the enterprise was in a state of temporary suspension of production, "The previous boiler did not meet the national standards, and it can be produced when a new boiler is replaced" … …

　　The reporter visited relevant enterprises in Shanghai, Tianjin, Chongqing and Anhui, and found that long-term poor management, bankruptcy, cancellation, closure, or loss of ownership and use rights of registered trademarks of old brands are the main reasons for these brands to be delisted.

　　New development of time-honored brands

　　Time-honored brands must face up to new consumption trends, new scenes and new demands, and innovate skills, products and management models while adhering to the core of excellent traditional culture, so as to keep up with the development of the times.

　　Dynamic supervision to ensure the quality of old brands

　　It is worth mentioning that the Shanghai Municipal Commission of Commerce introduced that 17 removed places will be used to recommend other outstanding enterprises to declare Chinese time-honored brands. Shanghai has selected from 104 newly recognized Shanghai time-honored brands, actively participated in the creation of a new batch of Chinese time-honored brands, and strived for more "in" than "out".

　　"Choosing the best among the best" and "going in and going out" are a major feature of the review of Chinese time-honored brands.

　　In order to promote the Chinese time-honored brands to adapt to the market mechanism and develop healthily, according to the Administrative Measures for the Demonstration and Creation of Chinese Time-honored Brands, in April this year, the Ministry of Commerce, together with the Ministry of Culture and Tourism, the General Administration of Market Supervision, China National Intellectual Property Administration and National Cultural Heritage Administration, deployed the demonstration and creation of Chinese time-honored brands, adhered to the working principle of "selecting the best among the best", established and implemented a dynamic management mechanism of "getting in and getting out", and conducted a comprehensive review of existing Chinese time-honored brands.

　　The relevant person in charge of the Ministry of Commerce said that the removal of 55 brands from the list of Chinese time-honored brands this time was the result of the review of Chinese time-honored brands announced by the Ministry of Commerce in conjunction with relevant departments after self-examination, local initial verification, expert review and social publicity.

　　In addition to the above-mentioned 55 brands that were delisted, the five departments also rectified 73 brands with poor management and declining performance within a time limit of six months.

　　"This is actually a deeper love for Chinese time-honored brands." Zhang Lijun, vice president of China Business Federation, said that we should focus on establishing and improving a long-term mechanism for the protection, inheritance and innovation of time-honored brands, promoting the advanced concept of benchmarking time-honored brands, conforming to the market mechanism, speeding up the innovation and development, and ensuring the quality of time-honored brands through a dynamic supervision system of "what goes in and what goes out".

　　Defending integrity and innovating "time-honored brands" began to actively transform.

　　In fact, more Chinese time-honored brands are not lying flat on the "golden signboard", but they are seriously "involuting" on the road of transformation.

　　Zhang Zhibin, general manager of a well-known catering management company in Zhengzhou, provided brand promotion support for several local "time-honored brands" in three cities in central Henan, namely Zheng, Bian and Luo. He was deeply touched by this. Zhang Zhibin said that the old brand actually means that the brand is aging, and its appeal to the main consumer groups is lacking. In addition, the catering environment is changing too fast. "In the past two years, we were still getting together for take-out. This year, the catering enterprises began to face the live broadcast of selling prefabricated dishes with goods — — These all make the old catering people at a loss. "

　　Zhang Zhibin said, fortunately, many "time-honored brands" that are aware of the problems have begun to make positive transformation. For example, a well-known snack brand in Zhengzhou has spent nearly one million yuan to redesign the space and graphic design of its storefront, and adjusted its brand positioning to actively move closer to young people through brand rejuvenation. Kaifeng’s local "time-honored" Huangjia time-honored store also began to invite Tik Tok bloggers to broadcast live the repackaged quick-frozen products with goods, "one set ‘ Combination boxing ’ Down, consumers clearly felt the new vitality of these old brand iterations, and really made the store turnover achieve a new high in recent years! "

　　In addition to the old brands that are undergoing active transformation, some old brands that were "awakened" earlier have now been completely reborn with innovation and "joint name".

　　The "No.0 Store" in Daoxiang Village, Beijing attracts many young people to queue up to buy with all kinds of snacks that are both fashionable and have Beijing charm; Changchun Hall, which has accumulated more than 200 years of traditional Chinese medicine culture, opened a new Chinese teahouse "Timely Drinking" last year. In addition, Quanjude, which sells roast ducks, introduced spicy moon cakes, and Wu Yutai, who sells tea, introduced matcha ice cream … … These time-honored brands’ actions of breaking through themselves and keeping their integrity and innovation have made young people eagerly admire them.

　　"In 2022, China’s time-honored enterprises achieved operating income of over 1.2 trillion yuan, and nearly 70% of enterprises achieved profitability. In the first three quarters of 2023, the operating income exceeded the level of last year. "On the day when the Ministry of Commerce disclosed the results of the review of China’s time-honored brands, He Yadong, a spokesman for the Ministry of Commerce, said that the Ministry of Commerce will further establish and improve the long-term mechanism for the protection, inheritance and innovation of time-honored brands with relevant departments, so as to promote the time-honored brands to dig deep into the cultural heritage, benchmark advanced concepts, maintain correct and innovative development, and better play a demonstration role.

　　People’s Daily Review

　　Time-honored brands should realize the unity of protection, inheritance and innovation and development.

　　Some people say that the advantages of time-honored brands are "old" and the disadvantages are also "old". "Old" means, on the one hand, polishing the technology, shaping the brand and accumulating the reputation for many years, on the other hand, it means that it is more urgent to solve the problems of outdated concepts, backward mechanisms and customer loss than young brands. With the development of the market, the supply of products is becoming more and more abundant, and the demand of consumers is becoming more and more diversified and personalized. When the long board is no longer prominent and the short board is increasingly apparent, the development of some old brands has entered a crossroads.

　　Survival of the fittest is the inevitable law of market competition. In this review, the brands with different management and development conditions were decided to be removed from the list, rectified within a time limit, and retained the title of China Time-honored Brand. This move, which conforms to the laws of the market, is conducive to ensuring the quality of the "golden signboard" of the old Chinese brand. At the same time, the dynamic management mechanism of "in and out" is also a warning to enterprises: being recognized as an old Chinese brand does not mean that you can sit back and relax. In the face of market changes and the impact of emerging brands, hesitating or lying on the credit book "eating the old money" is doomed to be defeated in the fierce competition and even eliminated by the market. How to keep up with the pace of market development and hand over satisfactory answers from consumers is a subject that every time-honored enterprise must answer well on its development path.

　　To meet the needs of eating healthier, develop new flavors with low sugar and low fat; In the face of increasingly personalized demand, the customized packaging of cross-border joint names was launched; Focus on the changes in consumption habits and channels, and actively touch the net to live with goods … … In recent years, many time-honored brands have launched new retail, innovated in production and sales, promoted brand rejuvenation and successfully explored the road of transformation. According to statistics, in the first three quarters of this year, the operating income of Chinese time-honored enterprises has exceeded the annual level in 2022, and the development momentum is good. On the opening day of this year’s "double 11" Shopping Festival, 85 domestic brands sold, and their sales exceeded 100 million yuan. The feedback from the market has proved that aiming at the new demands of consumers, keeping the innovation and development, we can polish the signboard of the old brand more and more brightly.

　　As a "golden signboard" bred in the history of China’s industrial and commercial development, time-honored brands have both high economic value and rich cultural value. The Notice on Strengthening the Linkage between Time-honored Brands and Historical and Cultural Resources to Promote Brand Consumption, jointly issued by the Ministry of Commerce, the Ministry of Culture and Tourism and National Cultural Heritage Administration, puts forward that "the time-honored brands should give full play to their positive role in promoting the sustained recovery of consumption and promoting the excellent Chinese traditional culture". Seize the opportunity of the rise of the national tide, fully tap and activate cultural resources to empower product quality and service, so that time-honored brands can cultivate more new consumption hotspots, better meet the people’s growing needs for a better life, and at the same time, cultivate competitive advantages and win the future.

　　Change makes sense, and general rules last for a long time. Accurately recognize changes, scientifically adapt to changes, take the initiative to seek changes, forge a long board based on advantages, keep pace with the times to make up shortcomings, adhere to ingenious quality, innovate products and services, improve quality level, and realize the unity of protection, inheritance and innovation and development. Time-honored enterprises will surely glow with new vitality and charm in the new era.

　　[car home reveals new car technology] The team was founded in 1929, entered F1 in 1950, won 16 team championships and 15 drivers’ championships. This prancing horse has achieved unprecedented results in F1. However, it seems that there is always a curse of "frustrated in the stadium and proud of the people" hanging over the heads of Italians. In this way, under the background of poor performance in F1 this year, this civil supercar named SF90 Stradale came to the stage. So can it, like its predecessors, not disgrace Ferrari’s name?

Pay tribute to the great history.

　　Compared with simple and rude advertising, it is the best proof of our own products or technical strength to go through the test of harsh competitions and get excellent results. The name of this new car just announced by Ferrari is a tribute to the past years. For an automobile company that focuses on designing and manufacturing products that pursue speed limits, glorious history is their military badge.

● Enter the electrification era.

　　"0-100km/h acceleration time is 2.5 seconds, and 0-200km/h acceleration time is 6.7 seconds". I believe this is the information that most people remember after reading the introduction of SF90 Stradale. Hidden behind this figure is the unremitting efforts of the engineering team. The 3.9T V8 engine that just won the 2019 International Engine Award has made great contributions again, but this time it is not alone, but there are three motors to help.

　　For Ferrari, it’s not enough to just surpass the opponent, and the victory of the crushing level is what the Italians want. In order to achieve the goal, engineers further optimized the V8 engine with a cylinder angle of 90 degrees, including simple and rude ways to increase the cylinder diameter to 88mm and the displacement to 3990ml. There are also optimization measures to increase injection pressure and reduce flywheel diameter. It is also obvious that the exhaust manifold is changed from steel to Inconel.

　　The SF90 Stradale has absorbed the development experience of its predecessors. It is equipped with three motors, two of which are located at the front axle and the third is located between the engine and the gearbox at the rear axle. Although it is a performance beast, it can still travel 25km in all-electric eDrive mode. In this mode, only the front axle dual motors work. You don’t have to worry about their insufficient performance. You can easily push the vehicle speed to 135km/h with only two independent front motors, and you can feel the longitudinal acceleration of ≤0.4g in the process.

　　Only the further development of the engine can not ensure that the new car can fully achieve its goal, and the role of the gearbox in the powertrain is indispensable. SF90 Stradale uses a brand-new 8-speed dual-clutch gearbox based on the existing 7-speed dual-clutch gearbox, and the weight of the whole machine is reduced by 7kg. In order to lose weight, the reverse gear of this gearbox is cancelled, and the function is taken care of by the motor. In terms of performance, the performance of the new clutch with optimized materials is improved by 35%, and the torque can be transmitted as high as 1200N·m during gear shifting operation. In addition, the shift time is further shortened, which is 30% faster than the previous 7-speed dual-clutch gearbox, reaching 200 milliseconds.

　　For super-running, it is necessary to run fast, steadily and stand still. The solution given by engineers is to use electric drive and traction control system. In addition, the brand-new brake-by-wire system combines hydraulic and electronic braking through electronic control. In general braking state, the motor recovers braking energy to complete deceleration. In case of emergency, the hydraulic braking system will intervene to enhance the braking effect.

　　Of course, everything is a double-edged sword. The increase of motors and battery packs will lead to an increase in the weight of the whole vehicle. The arduous task before the engineering team is lightweight development. The solution is not difficult for you to guess. Using composite materials on a large scale can improve strength and reduce weight at the same time.

　　Thanks to the application of new materials, the strength has been improved while losing weight. From the data point of view, the torsional stiffness of the chassis is increased by 20% and 40% compared with the previous platform. In addition, the NVH characteristics have also been improved.

　　If these are not enough for you, it doesn’t matter, the Italians have prepared another optional version for you-Asset to Fiorano. On it, you can find the shock absorber, carbon fiber door panel, titanium spring and exhaust pipe built according to the racing experience, which will be 30kg lighter than the former. In order to ensure that the surging power output by the engine can be transmitted to the road as much as possible, engineers also put forward higher requirements to Michelin, a tire supplier, which finally provided Italians with a customized version of Michelin Pilot Sport Cup2 tire with softer texture and fewer grooves.

Full text summary:

　　Whether it is due to regulations or the internal combustion engine technology is close to the bottleneck. This time, SF90 Stradale became the real beginning of legalist school’s development to a higher level of electrification. Aside from emotional factors, the cooperation between the motor and the engine makes its overall performance stronger. For such a supercar with Ferrari logo, the only shortcoming you can find seems to be too expensive. (Text/Figure car home Tang Dynasty)

　　There are 889 million people holding mobile phones in China, and this amazing data has undoubtedly pushed China to the top of the world in terms of the number of mobile phone users. In Chinese, a mobile phone is replaced every 15 months on average, but most of the old mobile phones are discarded at will, and only 1% of the old mobile phones are recycled.

　　Once discarded, discarded mobile phones, mobile phone batteries and charging equipment will contain a lot of harmful substances such as nickel and cobalt, which will cause great pollution to water and soil, and will cause hundreds of thousands of tons of electronic waste, which will inevitably lead to a great crisis of treatment. The pollution scale is much larger than that of other discarded electronic products such as discarded computers and color TVs. How to recycle and dispose of them has become a major environmental protection issue facing China.

　　In order to change this waste of resources, Nokia launched a program called "Green Box" in 2005, which placed collection boxes in more than 700 Nokia customer service centers and specialty stores in more than 300 cities for recycling used mobile phones. However, the number of recycled mobile phones is still very small, so where do the remaining discarded mobile phones flow?

　　David Kousemaker, a Dutch designer, arrived in Huaqiang North, Shenzhen, Guangdong Province, where he saw the scene of mobile phones being traded as raw materials and took the following photos. He wrote in his blog Tech Travels:

　　There are two tall buildings in a hidden corner of Huaqiang North Business District, where people are mainly engaged in mobile phone recycling. An entrepreneur told me that he bought these mobile phones in bulk from a wholesaler, who mainly picked up used mobile phones from garbage dumps in Hong Kong and another major Asian city.

　　Outside the building, I saw a man sorting out bags of mobile phone chips. I don’t know what he wants to do, but I guess someone wants to buy a mobile phone and he is looking for a matching mobile phone chip.

　　The plastic casings of used mobile phones will also be dismantled. Although we can’t get much oil and water from these casings, because the labor force in China is low, it can also be profitable to hire workers to dismantle the metal objects on the plastic casings.

　　Then someone will take down the components on the chip and pick, sort and classify them.

　　Next, they will remove the flux and solder from the component pins and further classify them. This is the most important step for many shops that renovate their mobile phones. But a little unexpectedly, this work is mostly done by girls and young women.

　　Some components are so small that they can only be operated with tweezers.

　　Foreign netizens think that China’s seriousness in recycling electronic waste is shocking, while other countries are not very concerned about it. They think it’s time to cheer and applaud China’s behavior. Of course, some people doubt the truth of this matter, and a little thoughtful ask: What are these recycled components used for later? Although some people also leave a message explaining that Huaqiang North Business District is a second-hand mobile phone market, it seems that they can’t resist the admiration of other netizens for China.

　　The practice that used mobile phones are refurbished by second-hand vendors and then sold is never the right way out. Parts and shells that lose value during the refurbishment of used mobile phones will be discarded by vendors at will, and some small workshops of used mobile phones will extract precious metals in the open air, which will directly dump the residual liquid and cause secondary pollution to the environment.

　　Since 2011, China has officially implemented the Regulations on the Management of Recycling of Waste Electrical and Electronic Products, covering refrigerators, televisions, washing machines, air conditioners and computers, but mobile phones are not yet listed. The scientific disposal of used mobile phones must be supported by policies. In China, the government, society and enterprises can jointly establish a recycling mechanism for used mobile phones and establish manufacturers — Two normal recycling modes: operators and municipalities. Relevant laws and regulations should list the behaviors that should be prohibited in the process of recycling discarded mobile phones and accessories, and clarify the legal responsibilities of related illegal behaviors. At the same time, the state supports qualified pollution-free recycling enterprises of electronic waste in terms of policies and taxes to engage in the recycling and disposal of discarded mobile phones and accessories. At the same time, it encourages major mobile phone manufacturers and related enterprises to jointly finance and establish professional mobile phone recycling companies.
