In the name of responding to the North Korean missile threat, the United States deployed the "Sade" anti-missile system in South Korea. Obviously, the monitoring scope of "Sade" goes far beyond the need of defending North Korean missiles, which directly harms the strategic security interests of China, Russia and other countries.

　 　 　 　　In response to the anti-missile deployment of the United States, the Russian Deputy Prime Minister said on July 31 that the missile system carried by the Russian "God of the North Wind" class strategic nuclear submarine can break through any anti-missile system.

　 　 　 　　Russia: "God of the North Wind" can break any anti-missile system.

　

　 　 　 　　Russia held a naval festival celebration on July 31st, and a documentary "Tsar of the Sea", which mainly introduced Russian "Yasen" class, "God of the North Wind" class nuclear submarines and North Devinsk Shipyard, met with the public. In an interview with Russian TV about the documentary, Russian Deputy Prime Minister rogozin said that no matter where the anti-missile system is deployed, the missiles carried by the "God of the North Wind" class nuclear submarine can break through its defense.

　 　 　 　　"God of the North Wind" is the latest strategic nuclear submarine developed by Russia. It is 170 meters long and 13.5 meters wide, with a maximum underwater speed of 29 knots, a maximum diving depth of 450 meters and a capacity of 107 people. It adopts advanced noise reduction technology, which makes it difficult to be found when carrying out nuclear strike.

　 　 　 　　Russian missiles have a "trick" to break through the anti-missile system

　 　 　 　　The "God of the North Wind" ship carries the "Blava" intercontinental ballistic missile, which was specially developed by Russia for the "God of the North Wind" class strategic nuclear submarine. It has a range of 8,000 kilometers and can carry 6 to 10 hypersonic sub-guided nuclear warheads. Each nuclear submarine can carry 16 solid-fuel "Brava" intercontinental ballistic missiles.

　 　 　 　　Where are these Russian missiles? Military experts pointed out that Russian missiles have the following three advantages: strong maneuverability and great difficulty in interception; The camouflage warhead is difficult to distinguish between true and false; The warhead is invisible and can avoid radar. It is with these special capabilities that Russia dares to declare that it can break through the US anti-missile system.

　 　 　 　　Us anti-missile attack on both sides, Russia deploying missile response　

　 　 　 　　In recent years, Russia has been playing a fierce game with the United States against the "anti-missile system."

　 　 　 　　In Europe, the United States used the Iranian nuclear issue as an excuse to vigorously promote the construction of anti-missile systems. On May 12, 2016, the land-based Aegis system of the United States in Romania was officially put into use, and on May 13, the land-based Aegis system in Poland started construction. In view of the European anti-missile system of the United States, on the one hand, Russia stepped up the deployment of iskander missiles; on the other hand, it inclined funds to develop and test new missiles, such as RS-26 Border and RS-28 sarmat.

　 　 　 　　In Asia, the United States deployed the "Sade" system in South Korea under the pretext of North Korean missiles. As a countermeasure, Russia deployed two of the three active "God of the North Wind" nuclear submarines to the Russian Pacific Fleet headquartered in Vladivostok. At the same time, Russia is also building new naval bases on disputed islands between Russia and Japan, which Russia calls the South Kuril Islands and Japan calls the four northern islands.

　 　 　 　　"shield" can be changed into "long sword" to break the strategic balance

　 　 　 　　As for the anti-missile systems deployed by the United States, Russian President Vladimir Putin once pointed out that these anti-missile systems claim to be for defense, but in fact, they will change their use from defense to attack without the knowledge of the host country, which will break the global strategic balance.

　 　 　 　　There is a "killer weapon" to deal with the US anti-missile Russia

　 　 　 　　In addition to the "Brava" intercontinental ballistic missile, in fact, Russia has several other killers to deal with the anti-missile system of the United States.

　 　 　 　　① "iskander-M" tactical missile

　 　 　 　　"iskander -M" is an advanced modern tactical missile of Russian army, which can carry all kinds of warheads, including nuclear warheads. It can be equipped with two missiles at each launching position, and it can launch two targets in one minute, with high flexibility, concealment and adaptability.

　 　 　 　　② "Jarls" missile

　 　 　 　　RS-24 "Jarls" intercontinental missile was developed on the basis of "Baiyang-M", with a range of 11,000 kilometers, and was rated as the strongest intercontinental missile by the Pentagon. "Jarls" missile has strong penetration ability, including multi-warhead technology and terminal maneuvering orbit change technology, which can greatly enhance the interception difficulty of potential opponents’ anti-missile systems.

　 　 　 　　③ sarmat intercontinental ballistic missile.

　 　 　 　　Sputnik’s article said that "Russian new intercontinental ballistic missile ‘ Sarmat ’ You can break through the defense system and raze Texas to the ground. " This new type of missile will be tested for the first time this summer. It will weigh at least 100 tons and can carry a load of 10 tons, while the current intercontinental ballistic missile weighs about 50-60 tons and the load is about 1-2 tons. Sarmat’s heavy weight and heavy load mean that it will carry up to 15 independently aimed sub-guided nuclear warheads, which may include mobile warheads that are more difficult to intercept.

CCTV News:Recently, many places have suffered from continuous high temperature weather. In order to ensure the normal operation of railway trains, railway departments in many places have strengthened the maintenance of air-conditioning equipment on lines and trains to ensure passengers’ safe and comfortable travel.

The reporter saw in Zhengzhou Depot that the train inspector was carrying out maintenance work on the train air conditioner on the iron roof more than 5 meters above the ground under the scorching sun. In hot weather, the normal operation of train air conditioning equipment is directly related to the comfort of passengers. Under the scorching sun, the surface temperature of the iron sheet on the roof is close to 60℃ or 70℃ at the highest, and the car inspector has to keep tossing and turning when stepping on it, and carry out operations such as disassembly, cleaning, dust removal and performance test on the 30 cm air conditioning unit.

Liu Yaofang, inspector of the depot inspection workshop of Zhengzhou Depot of Zhengzhou Bureau of China Railway:For the positions such as the inner cavity and evaporator that are easy to accumulate dust and cause poor refrigeration effect, we need to use soot blowing machines to dust these positions to ensure the best refrigeration effect of the whole air conditioning unit.

The higher the temperature, the busier the railway linemen are. Due to the property of thermal expansion and cold contraction of rail, it is easy to deform under the high temperature of the sun. In order to ensure the safety of railway operation in high temperature weather, railway linemen have to patrol the line on foot in high temperature. Railway rails, turnouts and fasteners should be checked one by one. It takes at least four hours to check the 10-kilometer railway line.

In addition, in Wuhai, Inner Mongolia, Linyi, Shandong and other railway stations, passengers are also provided with heatstroke prevention drugs and drinks such as Huoxiang Zhengqi water and mung bean soup in case of emergency.

　　Originated in England. In the 17th century, boatmen on the Thames often held boat races. In 1715, the first rowing competition was held to celebrate the coronation of the British king. In 1775, Britain formulated the rules of rowing competition and established the rowing club in the same year. In 1811, Eton College held the first eight-person rowing competition. In 1829, Oxford University and Cambridge University held the first inter-school rowing competition. In 1839, the rowing cup was held. In 1846, the British installed a paddle rack on the side of the boat, which lengthened the length of the paddle and improved the rowing effect. In 1847, the outer keel boat with overlapping plates was converted into a smooth inner keel boat, which improved the speed of rowing. In 1857, Babcock of the United States invented the sliding seat (said to be invented by Belgian athletes in 1865). When rowing, athletes can move back and forth to increase their leg strength. In 1882, the Russians changed the closed paddle into a movable paddle ring, which increased the rowing range. Rowing is similar to weaving shuttle, with two sharp and narrow ends. The materials, shapes and sizes of boats, paddles and paddle racks are not limited in principle, and are usually made of aluminum alloy or glass fiber reinforced plastic. The boat is equipped with a seat plate with pulleys, which can slide on two tracks. When rowing, athletes push their legs and pull their arms. Rowing is divided into events according to the number of passengers, weight, whether there is a helmsman or not, and whether to use single paddle or double paddle. The lightest weight of the helmsman is 50 kg for men and 45 kg for women. When the weight is insufficient, corresponding weights should be added and placed in the nearest place to the helmsman.Men have 10 events: single sculls, double sculls, lightweight double sculls, double single sculls without helmsman, double single sculls with helmsman, four single sculls without helmsman, lightweight single sculls with helmsman, four single sculls with helmsman and eight single sculls with helmsman, while women have single sculls, double sculls, lightweight double sculls, double single sculls without helmsman and four people. The race is 2000 meters for men and 1000 meters for women. Each channel is 2200 meters long and 12.5~15.0 meters wide, with 6 channels in general and 8 channels at most. Athletes must complete the race in their own channel. The ranking is determined by the order in which the bow reaches the finish line. Men’s rowing was listed as an event in the first Olympic Games in 1896, but it was not held because of the waves, and it was listed again in 1900. Women’s rowing was included in the Olympic Games in 1976.

　　In the 28th Olympic Games in 2004, there were men’s single sculls, double sculls without helmsman, double sculls, four single sculls without helmsman, four single sculls with helmsman, eight single sculls with helmsman, lightweight double sculls and lightweight four single sculls without helmsman. Women’s single sculls, double sculls, double sculls without a helmsman, four sculls with a helmsman, eight sculls with a helmsman, lightweight sculls with 14 events, a total of 275 athletes participated. The entry qualification is based on boats, and each association has a maximum of one boat for each event. There are three ways to qualify for the competition: first, the 1999 World Championship, second, the Olympic qualifiers in Africa, Asia and Latin America, and finally, the qualifiers held in Europe where all associations except Africa, Asia and Latin America can participate.

　　The rowing competition of the 2004 Athens Olympic Games will be held in the Schinias Olympic Rowing and Canoeing Center for 8 days, from August 15th to 22nd. It is estimated that 550 male and female experts from all over the world will participate in the competition, including 358 male players and 192 female players.

　　The single sculls boat is 8 meters long, 20 centimeters wide, and the lightest weight is 14 kilograms. There is an oar on each side of the boat. When rowing, the athletes turn their backs to the bow, sit on the seat plate that slides back and forth, and push their legs and pull their arms. Use the power of the left and right paddles to control the course. Men’s and women’s single sculls were listed as Olympic events in 1900 and 1976 respectively.

　 　 　 　CCTV News:At the press conference, in response to the problem of arrears of renewable energy subsidies, the relevant person in charge of the National Energy Administration said that the National Energy Administration and relevant departments have actively studied and explored ways and channels to solve the problem of arrears of subsidies.

　 　 　 　At present, some renewable energy enterprises are relatively short of funds because of subsidy arrears, but in fact these subsidy funds exist objectively and are guaranteed by government credit. Financial institutions are required to extend or renew loans according to the actual project and cash flow on the basis of independent consultation between banks and enterprises, or adjust the repayment schedule and repayment period to ensure the continuous cash flow of enterprises.　

　 　 　 　Li Chuangjun introduced that enterprises are encouraged to reduce their interest burden and share the interest pressure through green certificate trading, and do a good job in collecting the additional funds for renewable energy tariffs, so as to expand the sources of subsidy income and the scale of subsidy income. Priority will be given to granting subsidy funds to project enterprises that have voluntarily converted to parity, and at the same time, we will encourage projects and enterprises that have voluntarily converted to parity to continue to increase credit support, gradually alleviating and finally solving the problem of subsidy arrears.

　　In 2002, in order to celebrate the 35th anniversary of AMG’s birth, an engine production line relying on manual assembly was quietly completed. AMG is proud to be called“One Man – The sacred aura of One Engine is also engraved on the engine of every AMG model together with the name of the engineer at this time. In 2017, AMG ushered in a 50-year-old wedding ceremony, and IWC, which adheres to the same craftsman spirit, arrived as scheduled. What is expected is, what kind of gift will this "sturdy" watch god bring this time?

　　IWC International Engineers Sports Timekeeping Watch "50th Anniversary of Mercedes-AMG" Special Edition

　　Editor’s comment:The Universal "50th Anniversary of Mercedes-AMG" special edition watch is not a stunning work that you will never forget, and even you will feel that such an elegant dial design is deja vu among other brands. However, if you rotate the dial, the anti-magnetic soft iron inner shell inspired by AMG carbon ceramic brake discs will release Mercedes’ pursuit of speed in full, and its functionality and cultural connotation will also reach the extreme under the interpretation of precision timekeeping in the world.

　　A few days ago, Publicity Department of the Communist Party of China and the Ministry of Education selected 10 "the most beautiful college students" for the first time from the "College Students of the Year" who were studying. Today, let’s listen to their stories and pay tribute to their dreams and youth.

　　Broad world, flying the ideal of youth.

　　On the first day of college, Liu Qiang, an undergraduate of Northeast Normal University, made up his mind to be a teacher of ideological and political course, facing the motto of "being diligent and innovative and being a teacher".

　　Learn and talk about ideological politics. During school, Liu Qiang toured "Chasing the Light of Communism" in many colleges and universities, which led many young students to teach ideological and political courses by themselves. After the 19th National Congress of the Communist Party of China, he actively explored "micro-ideological politics+second classroom" and created an exchange platform for young people to "learn, speak and use" ideological and political micro-courses — — Learning "learning" clubs has ignited the enthusiasm of young students to learn new ideas and build a new era.

　　Countless youths are blooming in the vast world. Ashar Nurtai, an undergraduate student at Nankai University, also has his own ambition, that is, to become a soldier.

　　Ashar’s father is a martyr. In 2017, adhering to his father’s legacy, he volunteered to apply for enlistment. After joining the army, Ashar withstood the "devil-like" hard training of the recruits with tenacious will and tenacious character, and took the initiative to apply to join the special warfare squadron, completing two "transformations" from ordinary college students to recruits and then to special warfare players.

　　"As young people in the new era, we should let the flowers of youth bloom where the motherland needs them most." Ashar’s face showed a determined and confident smile.

　　Study hard and climb the peak of science bravely.

　　Yu Jiping, an undergraduate student in Tsinghua University. In 2015, when he first entered the campus, he saw that the Tsinghua student supercomputing team had won the news of the "Grand Slam" of three international competitions, and he became interested in supercomputing.

　　In 2018, Yu Jiping participated in winning three super-international championships. Yu Jiping said: "We will not give up the slightest chance to improve the computing performance. Every little makes a mickle to get faster and faster, and to win glory for our country."

　　The beauty of science also shines in the laboratory. Liu Xie, a Ph.D. student at Sichuan University, devoted himself to rock dynamics and engineering. In recent three years, he published 28 academic papers, 23 of which were included in SCI, won 14 national invention patents and software copyrights, and was the reviewer of 4 professional authoritative SCI journals & HELIP; … "I think my major is very interesting and meaningful. I like it very much." Liu Wei said.

　　Lu Song, a doctoral student at China University of Science and Technology, is also a veritable "schoolmaster". The self-generating safety helmet developed by him uses the heat emitted by human body during riding to generate electricity and give intelligent warning, which not only ensures riding safety, but also practices the concept of energy saving and environmental protection and won the gold medal in the 45th Geneva International Invention Exhibition. "Let cutting-edge technology no longer ‘ High cold ’ Really changing human life is the original intention of our scientific research. " Lu Song said.

　　Self-improvement, highlighting the value of life

　　The Wenchuan earthquake in 2008 dealt a heavy blow to Liu Min’s life. After being buried for 30 hours, she was rescued, but lost her right leg.

　　However, the strong Liu Min didn’t give in. After resuming her studies, she was admitted to Sichuan University and was sent to Nanjing University with excellent results. Not only that, she also initiated the International Forum on Post-disaster Reconstruction for College Students. Participate in the establishment of China Rehabilitation Engineering Foundation; Give inspirational speeches in many places to help more people get out of the haze.

　　After graduation, Liu Min decided to work for Sichuan Disabled Persons’ Federation. She said, "All losses are opportunities for growth. Now I am more determined in my heart and hope to do my best to help disabled friends, even if it is only a small change. "

　　Oriole, an undergraduate student of Wuhan University of Technology, also suffered a fate change. At the age of two, a high fever made her blind. However, the word "blindness" never seems to be an obstacle in Oriole’s life. In 2015, she was admitted to Wuhan University of Technology as a social work major, becoming the first blind student in China to take the general college entrance examination and enter the 211 key university.

　　Li Eryang, master student of Xi ‘an University of Finance and Economics. In March 2015, on the south bank of the Second Yellow River Bridge in Zhengzhou, Henan, Li Eryang found a child falling into the water. With good water quality, he jumped into the cold and fast-flowing Yellow River and tried his best to save people. However, I didn’t expect that Wu Zongyao, another student who was later supported by the water, failed to come back, which made Li Eryang very regretful.

　　Since then, Li Eryang resolutely joined the Red Cross Water Rescue Team in Zhengzhou. During the two months of summer vacation, he participated in the first-line on-site rescue 12 times and successfully searched for 9 drowning people. "Everyone who volunteers is glowing. Believe in the power of action, no matter how small!" Li Eryang said.

　　Innovate and start a business, and live up to youth.

　　Wang Shaoxin, a doctoral student in energy and resource engineering at Peking University Institute of Technology, deals with waste residue and waste gas from factories almost every day. His goal is to turn waste into treasure, turn waste residue into porous ceramics with high added value, and use it as a catalyst carrier, and load nano-materials on its surface to control air pollution, and finally realize "treating waste with waste".

　　At present, Wang Shaoxin has applied for 19 patents at home and abroad, and 9 patents have been authorized. At the same time, he founded Beijing Quality Enjoy Technology Co., Ltd. and obtained millions of angel round financing.

　　Ma Tianchen, a doctoral student majoring in network ideological and political education at the University of Electronic Science and Technology of China, is also struggling on the road of starting a business. Chengdu Taijutai Technology Co., Ltd., which it founded, successfully landed on the "New Third Board" in 2015, becoming the first company founded by college students and listed on the national stock exchange market during its school days. Ma Tianchen said with emotion that struggle is the background color of youth, and I hope that each of us can live up to ourselves, youth and the times.

When it comes to locomotives, many people first think of Kawasaki brand, and when it comes to Kawasaki’s specific models, everyone will definitely think of Little Ninja 250 for the first time. After all, this car has had excellent sales performance in the domestic market, so how much is this car? Let’s take a look at the official offer of Kawasaki Ninja 250.

According to the models once sold in the domestic motorcycle market, the prices of Kawasaki Ninja 250 are as follows:

Model year factory guide price Kawasaki Ninja 2502014 model 43900 yuan 2017 model 43900 yuan 2018 model 43900 yuan Kawasaki NIJA 250KRT version 2020 model has no quotation at present.

As can be seen from the above table, the official price of Kawasaki Ninja 250 is stable at 43,900 yuan, but it should be noted that this car was officially delisted from the China market after the 2018 model, so even if you have money, you can’t buy a brand-new Kawasaki Ninja 250 now, which is why there is no manufacturer’s quotation for the 2020 model.

Although we can’t buy a new car, Kawasaki Ninja 250 is still very active in the second-hand motorcycle market. Among them, the price of second-hand Ninja 250 in 2015-2019 ranges from 16,000 to 28,000 yuan. The specific price needs to be determined according to the condition of the car. It should be noted that second-hand motorcycles have deep water. If you buy a car, it is recommended to bring a friend who can look at the car to check it.

If you can’t accept used cars, you can also consider the brand-new Kawasaki Ninja 400, which can be said to be the successor of Little Ninja 250. Ninja 400 not only has a larger displacement, but also has a better control experience. Its product strength is much higher than that of Little Ninja 250, and the domestic trade price is 49,800-00 yuan, which is only five or six thousand yuan more expensive than that of Little Ninja 250.

Seeing this, I believe everyone has a certain understanding of a Kawasaki Ninja 250. It should be noted that it is easier to buy a car than to maintain it. You know, playing motorcycles, especially motorcycles, is a very expensive thing. If your financial strength is not strong, I suggest you don’t buy a motorcycle easily.

　　"I want to find a domestic aunt who can take care of the children and take charge of breakfast and dinner. How can it be so difficult! The favorite domestic aunt is not only hard to find, but the price is getting higher every year. " Recently, Jiang Lin, who works in Beijing, was busy looking for a suitable domestic aunt. In half a month, she attended five meetings of intermediary organizations but found nothing. Seeing that the children at home are not picked up at school, she is getting more and more anxious.

　　In cities, many dual-income families like Jiang Lin find it difficult to take care of children, the elderly and work at the same time. The most convenient solution is to choose a reliable domestic aunt to help. Recently, our reporter found at several job fairs in Beijing that there is a strong demand for services in the domestic service industry after the year, but "good aunts" are hard to find.

　　The demand for domestic service personnel is rising.

　　"From the new moon to taking care of the elderly, every time I look for a domestic aunt, it’s like ‘ Open the blind box ’ 。” Li Qiran’s family, who lives in Shunyi, has encountered problems such as intermediary running, fraudulent resume and running-in difficulties. "Two-employee families take care of the old and the young, and domestic service is just needed. Choosing a good aunt can really help a lot." Li Qiran said.

　　In the domestic market, aunts with rich experience, comprehensive skills and excellent evaluation are hard to find. Ms. Tian, the person in charge of a domestic service intermediary company in Haidian, Beijing, told the reporter: "At the beginning of the year, there were many families consulting domestic service, and most of the needs were childcare and housework. At present, the mobile phone platform has the largest number of consultations, and nearly 20 people can be interviewed every day. "

　　"Auntie who has been engaged in domestic service for a long time, the orders are basically seamless." Ms. Tian revealed that "day shift housekeeping varies greatly according to the needs of employers, workload and working hours. Aunt at home is basically more than 6500 yuan per month, and the price of only being responsible for household cleaning will be lower. If you need skilled domestic workers such as new moon, nursing and housekeeper, the salary can reach more than 10,000 yuan. "

　　The data shows that the domestic service market in China shows a continuous growth trend, and it is expected to increase to 1,164.1 billion yuan by 2023. The job-seeking data of a recruitment platform in the first quarter of 2023 shows that in February, the overall recruitment demand of domestic enterprises increased by 94.22% month-on-month, and in the first quarter, the overall job-seeking demand of domestic enterprises increased by 7.18% year-on-year, with strong demand. Especially in terms of "providing for the aged" and "raising children", the demand scale will continue to rise.

　　With the rising demand for domestic service personnel, domestic aunts also have more considerations of their own. "During the interview, due to factors such as inconsistent living habits, respect from employers, and distance from home, more aunts chose to take the initiative to go to the household." After interviewing nearly 10 aunts, Jiang Lin felt, "Now, finding a domestic aunt is a two-way choice process."

　　Supply and demand are difficult to match.

　　According to the data of a consulting company, more than 40% users in the domestic service industry have had disputes with domestic workers, among which the working attitude and professional level of domestic workers are the most important reasons for disputes.

　　At present, in the domestic domestic domestic market, employees are still concentrated in the "4050" female groups all over the country. They usually register for job hunting in many institutions, and their past work experience is diverse and highly mobile. People who have been engaged in domestic service for a long time are scarce, and the characteristics of "odd jobs" are obvious. These professional characteristics lead to great differences between employers and workers in parenting concepts and cultural levels. On the Internet, some lightning protection posts about the fraud of the resume of the aunt’s business certificate, the lack of practical training, and the arbitrariness of work have caused many people to feel the same way. The irregular behavior of some platform intermediaries or employees leads to a decrease in the overall evaluation of the industry.

　　Ms. Yu Qin from Hebei told the reporter about the routine she had encountered before: "Some aunts quit their jobs within a week after they arrived at home, some paid a lot of agency fees but could not introduce a good aunt, and there was an excuse to ask for an upgrade of membership or a salary increase … …”

　　"In the final analysis, it is a problem that the industry is not standardized, and employees have no clear skill evaluation criteria. A variety of certificates and ratings make consumers unconvinced. " Zhangyan Hua, an associate professor at China Institute of Labor Relations, said that domestic service companies lack uniform industry service standards, and companies and platforms act on their own, with different charging standards for the same service content and arbitrary service prices, which leads to poor employers’ experience, which is not conducive to the development of the industry.

　　Promote the long-term stable employment of domestic workers

　　With the continuous expansion of domestic domestic housekeeping industry, the ability of domestic housekeeping industry to absorb employment is becoming stronger and stronger. In 2021, the number of employees has reached 37.6 million, but at present, there is still a large gap in the domestic service industry, which is in short supply. At the major job fairs in Beijing years later, many domestic companies offered high salaries and relaxed recruitment conditions to supplement the lack of domestic workers.

　　"Although domestic companies offer high salaries, there are not a few cases in which domestic workers work for a short period of time, and they are fired or voluntarily leave their jobs after working for the same employer for a few months. The domestic workers as a whole ‘ Empty window period ’ Longer. " Professor zhangyan Hua analyzed, "Domestic workers have long working hours, little rest and vacation, and lack social security. There are still many introductions from relatives and friends, but only verbal agreements or commitments. Once disputes arise, they are often scattered and lack long-term and stable employment relations. "

　　"Promoting the long-term and stable employment of domestic workers in cities is a long-term and arduous task, which requires a multi-pronged approach." Zhangyan Hua said that trade unions can organize domestic service personnel through online platforms or other flexible ways, and consciously strengthen skills training such as vocational skills, legal knowledge and interpersonal communication, so as to improve the quality of employees and strengthen the cultivation of domestic talents.

　　In February this year, the three departments jointly issued the "Special Action Plan for the Standardization of Pension and Domestic Service", proposing the overall goal and key tasks of the standardization of pension and domestic service by 2025. In this regard, Zhang Yanhua believes: "Giving full play to the role of industry associations and formulating unified skills identification and rating standards for domestic service personnel according to different service contents can reduce the arbitrariness of domestic enterprises, enhance employers’ confidence and trust in the industry, and promote the standardized development of the domestic industry."

[Interpretation of car home’s New Technology] Speaking of Bosch, you are no strangers. This well-known enterprise from Germany has too many auras and countless fist products. But if I tell you, these guys have recently developed many strange technologies, such as intelligent drift, old drivers braking … You must doubt whether Bosch engineers are working seriously? Don’t worry about the evaluation, let’s follow our footsteps and come to the Bosch (Hulunbeier) Automobile Test Technology Center with a cold wind to find out.

zeroThe motor started too hard? DTCS: arranging

In order to better control the vehicle, Bosch developed ESP? in the era of internal combustion engine. Body electronic stability control system and TCS traction control system. To put it simply, the former can reduce the offset trajectory of the vehicle during sudden braking and improve the braking safety by quickly braking continuously and adjusting the braking force of four wheels; The latter is to control the output power of the engine to ensure that the vehicle will not be out of control because of excessive acceleration torque.

The unique torque output characteristics of the motor really shorten the speed-up time of 0-100km/h, which brings an acceleration experience that many high-performance engines can’t match. But it is precisely because of this feature that it is easy for tires to break through the adhesion with the ground, resulting in vehicle instability. To put it bluntly, it is-slipping at the beginning.

Due to the output characteristics of the engine, the increase of torque needs to wait for the increase of rotational speed, so the delay of 100ms is completely sufficient. Even if many high-performance vehicles step on the accelerator deeply in the initial stage, it is not easy to cause slippage with the help of TCS.

However, the torque output of the motor is explosive, and the speed can be increased to more than 10,000 rpm in an instant, which makes the traditional TCS seem a bit "late". Therefore, Bosch engineers try their best to shorten the trigger delay of TCS according to the characteristics of the motor. Thus, the distributed traction control system dTCS was born.

According to the official disclosure, it takes only 10ms from the wheel speed sensor sensing that the vehicle is slipping to the completion of the torque limiting operation. It’s like the "high-Ping warrior" in the team just now turned on a game accelerator, and naturally he can get a better game experience.

Not only that, this set of dTCS also supports OTA upgrade. As long as the model is equipped with Bosch’s IPB intelligent integrated braking system, in theory, new functions can be written through OTA. However, at present, the official has only opened this function to Han EV. As for when other models equipped with IPB can enjoy it, it still needs specific planning.

zeroKinetic energy recovery is also slipping? EDTC: I will do it.

Many electric vehicles will automatically activate the energy recovery function when the vehicle releases the accelerator pedal to convert the wasted kinetic energy into electric energy and store it again. Frankly speaking, it is the "single pedal mode" promoted by many car companies.

EDTC has the same effect as dTCS mentioned above, and it also integrates this software algorithm into MCU motor controller. However, it controls not the "acceleration torque" output by the motor, but the "deceleration torque" generated by kinetic energy recovery. By shortening the communication path, the delay of issuing instructions is reduced.

In fact, dTCS and eDTC have one thing in common, which is to transfer the algorithm originally designed in the braking system to the motor controller. We should know that electronic control is one of the three cores of new energy vehicles. Nowadays, the design of electronic control system of vehicles is often in the hands of car companies themselves. If you want to write a black box algorithm here, it must be a very close cooperative relationship. However, according to Bosch’s engineers, they have already landed projects, and it is estimated that before long, things that can save lives at these critical moments will be quietly arranged in our car.

zeroBaby mode: Say goodbye to the brakes.

Maslow first put forward the hierarchy of needs theory in a paper "A Theory of Human Motivation" in 1943. Generally speaking, after meeting the security needs, human beings will begin to pursue higher-level needs. Such as socialization, respect and even self-realization. The same is true in the automobile field. After cars become more and more safe, the demand for comfort and entertainment begins to surface gradually.

Many consumers are prone to feel uncomfortable when riding a car, and one of the most important reasons is to brake and nod. At the moment when the vehicle is about to stop completely after deceleration, if the driver is not an old driver and doesn’t know to take a little throttle, then the last "trembling" will make the unsuspecting occupant lean forward and then be thrown back to his seat.

CST 2.0 relies on Bosch’s decoupled intelligent braking system, and both DPB and IPB can realize this function. Simply put, the model-based algorithm releases a certain braking pressure for the driver at the moment when the vehicle is about to stop. Even if the driver doesn’t loosen the oil, the vehicle can realize the effect of loosening the oil independently.

Then some friends may ask, won’t the braking distance be extended if the vehicle releases the braking pressure on its own initiative? What if it leads to a rear-end collision? We can think of problems, and engineers can certainly think of them. Therefore, this technology has considered several situations at the beginning of design.

● In case of emergency braking, whether the driver operates or the AEB system is triggered, CST 2.0 will not be activated when the deceleration of the vehicle reaches a certain threshold. The vehicle can be under the ideal braking force until the vehicle stops. After all, it’s almost hit, so don’t pay attention to comfort and discomfort. Safety comes first.

● If the vehicle triggers the ABS function for various reasons, CST 2.0 will not be activated. This tire is almost hard to grasp, so let’s forget about nodding. It’s reasonable.

● If the vehicle is driving on a ramp and the gradient exceeds the preset value, CST 2.0 will not be triggered for safety reasons. If you really want to learn from the old driver, you will be in trouble.

Technology alone is not enough. If you want to sell something, you have to rely on packaging. Bosch engineers have even named the function: according to different softness, this function can be switched between "baby mode", "commuting mode" and "customized mode" at will. According to my actual experience, I think the baby mode experience is the most comfortable, and I can hardly feel any brake nod. You just pedal and leave the rest to CST 2.0.

zeroIntelligent drift? Just get in the car?

What is the most important thing to do when you come to the ice and snow field? Of course, driving a car is a hearty drift show. However, it is very difficult for most drivers to control the vehicle stably in this state that is about to get out of control. The accelerator pedal is too small to break through the grip limit, and the floating fails; When the accelerator is stepped on, the vehicle oversteers and turns in circles. So, if there is such a technology that can help drivers control the power output of vehicles, will drift become very simple? Bosch calls this technology iDCS, which is the intelligent drift system of new energy vehicles.

The traditional car drift skills are actually very complicated. It requires the driver to break the grip balance of the rear wheel through the cooperation of the throttle and the steering wheel, resulting in "tail flick", and then adjust the angle of entering the corner in the reverse direction. It is also necessary to constantly correct the throttle opening and steering wheel angle to keep the vehicle in a state of insufficient grip. Even experienced drivers need to choose familiar vehicles and practice for a long time to ensure stable and controllable drift and perfect posture.

Even a driver like me, who is not good at drifting, can simply drift with the help of iDCS. As the trajectory of the vehicle is gradually straightened, the accelerator pedal is pressed again in the reverse direction while releasing the throttle, and the vehicle will adjust its attitude and drift in the reverse direction under the control of iDCS to complete a classic "pendulum" action.

"The cooperation of front and rear axle dual motors is not the difficulty of iDCS, even if there is only a rear axle single motor, this technology can be applied. Its complexity lies in the matching of different models. Because the chassis and suspension characteristics of different models are different, targeted adjustment and calibration can make it complete the drift action instead of Spin. "

This system does not need additional hardware support, in other words, "just have a wheel." It can not only be a good helper for drift introductory teaching, but also become a unique selling point of high-end new energy vehicles. It is understood that Bosch has even started a specific cooperation project with a new energy brand in China, but when we asked which OEM it was, the engineer said that it could not be disclosed for the time being.

zeroWrite it at the end

In fact, a day’s ice and snow experience is far more than the above contents, such as VDC 2.0 vehicle dynamic control system, off-axis torque distribution eDTD, and steer-by-wire system SBW, which are not easy to display in graphic form. We will share them with you in the form of video in the future.

I have to say, once the supplier starts to play dirty, there will be nothing wrong with the OEM. Now they not only have to develop various technologies about safety for their customers, but also have to constantly innovate and toss some interesting "tricks". Even the product name has been given, and it is really "rolled up". I hope that all major car companies will work harder and don’t let Bosch steal the limelight. I also hope that these practical and interesting functions can be introduced to the market as soon as possible, so that we can have a good experience on the commercially available models.
