In China, the number of take-away users has reached 360 million, and the average daily order volume is tens of millions. In order to serve these hungry diners, there are more than one million take-away riders rushing around the streets of hundreds of cities across the country.

Each color in the picture above represents a rider.

Takeaway riders are a group of energetic "little brothers":Nearly 70% of them are under the age of 35, and more than 90% are men.. Although the proportion of "little sister rider" and "big brother rider" is low, they don’t let a young man be old and strong, and their work performance is equally excellent.

On average, a riderI have to work 8 hours a day, stand by for 12 hours and deliver 48 orders.. If the average distance between merchants and diners is 3 kilometers and each order is 1.5 people, the rider travels nearly 150 kilometers every day, saving diners 100 hours and walking 400 kilometers less every day.

And this is just a microcosm of millions of riders. Behind this microcosm, there are more data details; Behind the details of the data, it is the embarrassment that riders exchange sweat for a better life.

Hard-working riders

The horizontal axis represents time and the vertical axis represents order quantity.

Four o’clock in the morning is the quietest time of the day in Shanghai, a super city. Most residents have fallen asleep, and the riders have started the "handover" of work: the riders who have delivered the supper can finally get off work, and another group of riders get up early to prepare for the first breakfast today.

A qualified rider must have a good physical strength, get up in the morning and endure at night.

However, super endurance is only part of the rider’s necessary working ability.

Each horizontal rectangular combination in the figure represents the working state of a rider on a certain day in July 2018. The period marked in blue indicates that the rider is running on the road, and the period marked in white indicates that the rider has no pick-up ticket or is in a rest state.

As can be seen from the above picture (combined with the above picture), the working hours of riders are highly fragmented. The rider’s workload is not evenly distributed in all time periods: every time the order for "meals" comes like the tide, the rider must work continuously for several hours with high intensity; However, there are fewer orders during the non-"meal" period, and whether you can grab the order successfully depends on your hand speed.

Working 8 hours a day, waiting for 12 hours, cycling between high-intensity running and fragmented grabbing, this is the real working state of the rider.

These are just the "daily" of the rider. Special weather conditions are the real test for riders.

Based on non-rainy days, the heavier the rain, the more take-away orders.

It can be seen that the number of orders in rainy days is far more than that in non-rainy days, and even close to 1.7 times in rainy days. At this time, some riders will choose to rest in rainy days, while others regard rainy days as an excellent opportunity to run more singles.

Real riders dare to face up to the surge in orders and the bad weather.

A variety of styles of riders

Generally speaking, the work area of each rider is relatively fixed (you can go back to the first picture at the beginning), and it is more efficient to be familiar with the store and familiar with the door. However, the size of each rider’s "territory" varies greatly.

In the picture above, a dot represents a rider. The horizontal axis represents the main activity range of the rider (95% threshold of latitude and longitude of the area visited in a week, converted into square kilometers), and the vertical axis represents the average daily riding distance of the rider in kilometers. The more riders in this area, the deeper the blue background.

We selected a group of riders with average daily orders (about 45 orders), and counted their range of activities and average daily riding distance. It can be seen that the smallest range of activities of these riders is only 18 square kilometers, and the larger one is close to 35 square kilometers. Although the range of activities is nearly 2 times, everyone’s riding distance is about 150 kilometers. Why is this happening?

We can guess:Although the goal is "running less and running more", different riders have different working styles.

Based on this speculation, we selected 11 dimensions to represent the rider’s food delivery style, and conducted principal component analysis (PCA) on these dimensions.(These 11 dimensions include: working hours, fragmentation of order time, proportion of lunch orders, proportion of dinner orders, proportion of meal orders, proportion of supper orders, average distance per order, size of activity range, ratio of length to width and radius of activity range, proportion of drop-by orders and average delivery time per order. )

[Readers who are not interested in PCA can skip this picture without affecting the full-text reading]The above figure depicts the importance of the two principal components of PCA. The horizontal axis is principal component 1, the vertical axis is principal component 2, 11 arrows represent 11 variables, and the coordinates represent their projections on the two principal component axes. It can be seen that the rider’s food delivery style has two basic components: time (principal component 1) and space (principal component 2). And the drop-in list and the average delivery distance per order are the combination of time and space components.

On this basis, we carry out K-means clustering and divide the work style of riders into 9 categories. As shown in the figure below, each point in the figure represents a rider, and riders in the same polygon have the same style.

From the nine styles, we select four most distinctive ones and analyze them.

The first type: "velocity flow" style

The above picture shows the activity path of a rider with a "speed flow" style at a certain time of the day. Blue marks represent riders, red dots represent restaurants, yellow dots represent customers, and blue lines represent riders’ running paths. It can be seen that the rider’s activity area is not large, and the restaurants and customers are very dense.

The riders of "Speed Stream" are mostly active in densely populated and order-intensive areas (such as the city center). Their characteristics are small activity range (average 20 square kilometers) and fast food delivery (average delivery time is 23 minutes). They can usually get more orders and better customer comments.

The second type: "downstream flow" style

We define the concept of "drop-in order": the rider has also handled other orders during the process from picking up meals to delivering meals. The meaning of "downstream flow" is "high proportion of downstream bills". The above picture shows the activity path of a rider with a "downstream flow" style at a certain time of the day. In the rider’s activity area, the location of restaurants and customers is sparse. This rider often runs several restaurants and then several customers in a row.

A bold and cautious rider is not afraid of running far, and he is afraid that there are not many orders; No Jin Gangzuan, no porcelain work. The average range of activities of "Riverside Riders" is 30 square kilometers, but as high as 80%, they don’t need to run many more roads. Adopting this working style not only tests riders’ familiarity with road buildings in the area, but also tests their ability of route planning and time control, and it is also a great challenge to the ability of improvisation.

The third type: "grab a meal" style

The above picture shows the activity path of a "grab a meal" style rider at a certain time of the day. The rider didn’t go to work until 11 o’clock in the morning, and he was so busy that he flew. 1-3 pm, the rider has a long rest; Get busy again around 4 o’clock.

About 60% of the riders’ orders in a day are concentrated in lunch and dinner (the industry average is 45%). They combine work and rest, go all out at the peak of the order, their hands and feet are much faster than their peers, and they have a good rest after heavy work until the next meal arrives.

The fourth type: "Desperate Lang" style

The above picture shows the activity path of a "Desperate Lang" style rider at a certain time of the day. The rider ran continuously from 7: 00 a.m. on June 19th to 1: 00 a.m. on June 20th for nearly 18 hours.

There are some riders. They are on the road when you have breakfast, and they are still on the road when you have supper. High attendance, many running orders, flowing customers, iron brother. It’s hard to travel for an average of 12 hours? "Desperate Lang" smiled, turned around and set foot on the journey again.

In the invisible competition with time and space, take-away riders are far from being as simple as "eating bitter".In the seemingly repetitive and monotonous rush, the rider combines the characteristics of his own ability and the characteristics of his work area, and develops his own style with experience and wisdom to complete his work and serve customers more efficiently.

One order after another, day after day. Riders appear in our mobile phone call records almost every day, and they are the most familiar strangers. They work hard and struggle for wisdom, so that we can have hot meals on time.

However, in recent media reports, people tend to pay more attention to accidental events such as "being late" and "poor attitude", while ignoring the punctuality and hospitality of riders most of the time.

Like many workers who have left their homes, riders have crossed hundreds of kilometers to integrate into the cities that give them hope, and they have fulfilled their promise of "on-time delivery" to customers with hard work. On the way of the rider’s food delivery, there are storms, competition, tempering and growth. When "little brother" gradually becomes "big brother", they may say something like this:

"A man’s life should be spent like this: when he looks back, he will not regret for wasting his time, nor will he be ashamed of being mediocre. When he retired, he could say: My beautiful youth and peak energy have been dedicated to the most magnificent cause in the world-the struggle to make human beings eat.

　　International institutions have raised China’s economic growth expectations.

　　Recently, the World Bank, the International Monetary Fund and other international organizations and institutions have raised China’s economic growth expectations. Liu Aihua said that although the external environment is complicated and changeable and the domestic economy is facing some difficulties and challenges, the fundamentals of China’s economic recovery and long-term improvement have not changed.

　　From the perspective of production, innovation kinetic energy has been continuously cultivated and enhanced, and industrial transformation and upgrading have been solidly promoted; From the demand point of view, with the implementation of consumption promotion policies and the innovation and expansion of consumption scenarios, consumption potential is expected to be further released.

　　Expert: The policy continues to exert its strength in expanding demand.

　　Experts believe that looking forward to the next stage, external demand will continue to maintain resilience, and exports will maintain rapid growth in the short term, which will boost the formation of related industrial chains. Policies continue to play a role in expanding demand, especially fiscal policy, which has sufficient room for development and is expected to play a supporting role.

　　China’s economy continues to pick up and improve.

　　The World Bank recently released the China Economic Briefing, which raised China’s economic growth forecast by 0.3 percentage points in 2024. On June 17th, the National Bureau of Statistics introduced the operation of the national economy in May, and various economic indicators continued to rise to a good trend, which attracted public attention.

　　South Korea’s "Asian Economy": Export growth rate hit a new high.

　　The article points out that since 2024, China’s foreign trade has gone out of a very difficult rebound curve, and external demand has continued to recover.

The upward forecast is mainly based on objective economic data and a series of measures taken by China government to promote economic growth. A more balanced and comprehensive policy is an important guarantee for China’s sustained economic recovery.

0.2 million/200 thousand to buy a gas car or a tram When this issue is raised, it shows that the domestic new energy market has been overwhelmed. After all, in the past, the first choice of consumers was the Japanese Three Musketeers. But now the situation is different, and major car companies are desperately involved. As a result, many large and medium-sized new energy family cars have emerged in the 200,000-class market, including the starter BYD Han, and the latecomers such as Zero Run C01 and Changan Qiyuan A07.

In order to seize the inherent position of this former fuel vehicle, Roewe brought the D7. At present, there are two versions of the new car, EV and DMH. In the noisy domestic market, how will the new car be enlarged? The price is the highlight, and it has fallen below the 130,000 mark.

The price range of the new car is 125,800-176,800, and there are 6 models to choose from. Among them, the EV version is priced at 149,800, and the listing rights are superimposed. The plug-in version is finally sold at 121,800, and the threshold for the pure electric version is 143,800. Today, let’s take the EV version as an example to see what it has besides the volume price.

Pure trams talk about manipulation? Rear drive is the key.

Now every new energy vehicle will have its own label after it comes out, which may be smart, endurance or safety. Roewe D7 EV mainly aims at performance control. At present, most pure trams on the market are in the front layout. Roewe D7 EV, which comes from the pure electric platform of SAIC Nebula, adopts the rear drive structure.

In this way, the front and rear counterweights of the vehicle are more balanced, and the front wheels are only responsible for steering, which makes the vehicle more maneuverable. The new car adopts front McPherson and rear five-link independent suspension system. According to the media feedback of the previous test drive, the support of the whole vehicle in cornering is good. Even if you pass through a mountain road or brake suddenly, the vehicle is relatively stable.

In terms of power output, the whole vehicle adopts VGA six-in-one motor. The maximum power of the system is 155kW, the peak torque is 310N·m, and the zero acceleration takes only 6.5 seconds. Equipped with two Rubik’s cube batteries with different power, the cruising range of CLTC is 510km and 610km respectively. This level is enough to cover daily traffic scenes and alleviate endurance anxiety.

The Rubik’s cube battery, while ensuring long battery life and safety, also lies in the optimization of space and shape. Its thickness is only 110mm, which makes the car more spacious, and the back row has no disadvantages of the previous high platform of new energy vehicles. When you don’t need to think too much about the battery occupying a large space, the degree of freedom in design is relatively higher.

Is it comfortable to play with new energy? Far more than intelligence

When it comes to middle and senior family cars, it is basically inseparable from the creation of comfort. Many old-school players start with space and seats, such as the big sofa we are familiar with. When it comes to new energy sources, the concept of comfort has new extensions, such as intelligence.

The zebra zhixing system, which first made Roewe famous in World War I, has been upgraded. The dual 12.3-inch LCD screens installed in the car are equipped with the latest car system, which has the functions of multi-meaning, talking and executing, and can also realize the seamless flow of mobile phone and car information. With many apps such as iQiyi and Netease Cloud, the entertainment in the car is enriched when the sense of operation is improved.

At the same time, D7 is also equipped with L2 intelligent driving assistance, including eight functions such as ACC full-speed adaptive cruise and AEB automatic emergency braking. With 540 HD panoramic images and other functions, you can have a comprehensive and clear understanding of the state of the vehicle. Through the blessing of software and hardware, the travel safety is guaranteed.

Of course, this is only part of the comfort of new cars, and the space that consumers fancy is another big attraction. The interior structure optimized by Rubik’s cube battery continuously expands the interior seating space. The length, width and height of the new car are 4890/1872/1510mm respectively, and the wheelbase is 2810mm. The car length of nearly 4.9 meters and the wheelbase of more than 2.8 meters make the rear space spacious and comfortable.

For the classic big sofa of the joint venture car in the past, the new car also gives its own gameplay. Mainly from the aspects of material and support to create the comfort of the seat. The seat is covered with a large area of suede, and the interior is filled with 9 layers of materials, matching the quilting process, which makes the whole look comfortable and advanced. Details such as the U-shaped embracing design in the front row bring good support. Coupled with memory, ventilation, heating and other functions, it makes driving more convenient and comfortable.

For the pursuit of cabin comfort, the car also gave other surprises. For example, the main driver has a one-button big lying function, and after the seat is unfolded, it can change into a 1.7m cot every second. For long-distance travel, this function is quite intimate. Of course, after the seat is leveled, it can be changed into other layouts, and the double bed is very suitable for the current camping scene.

Roewe D7, as the first model of "D family", adds a lot of points to the design of the new car. The front of the car adopts a closed front face, and the split headlight design looks very eye-catching. At the same time, a large area of blackened decoration is added to the bottom of the front enclosure, which is matched with the blackened air inlet to make the front face more energetic.

The side adopts a slip-back design to ensure that the rear head space makes the whole car elegant and dynamic. With the concealed door handle, it is helpful to further optimize the wind resistance coefficient.

The tail is a split taillight with personality, which brings high recognition with the upturned duckling tail. The blackened decorative piece at the back surrounding the bottom echoes the front face, which enhances the dynamic properties of the whole vehicle.

Write it at the end

Needless to say, Roewe D7 EV can always find its own direction. Starting with the rear-drive control, supplemented by battery safety, large space and intelligent creation, its image is full and three-dimensional. Combined with the starting price of less than 150 thousand, we found our own breakthrough among the competing products. Of course, the ultimate beneficiaries of product competition are consumers, and the listing of new products means another choice for buying a car.

[car home Shantou Preferential Promotion Channel] At present, preferential promotion activities are being carried out in Shantou area. The highest discount range can reach 20,000 yuan, and the lowest starting price is only 68,900 yuan. If you are looking for a high-performance and cost-effective SUV, now is the best time to start.

Matching this engine is a 7-speed wet dual-clutch gearbox, which makes power transmission more efficient and smooth.

The evaluation of Changan Auchan X5 shows that the young and fashionable design of this model is deeply loved. He said, "The appearance is young and fashionable, and the design is unique, especially in line with the aesthetics of most young people now. Moreover, his body decoration also has a sporty style. Because of the love of young people, I later added a shovel kit before sports. I like it even more. Front shovel: The front shovel is completely personal preference, and it was added later, which makes me feel very handsome. " This user’s spontaneous modification further proves that the design of Changan Auchan X5 is very attractive.

Wild roe deer in the administrator’s lens

In the early winter, when the sixth ecological replenishment of Tangzhishan Reservoir started, this water area welcomed three surprising visitors — — Wild roe deer. This discovery made the Tangzhishan Reservoir have the trace record of the roe deer for the first time.

Recently, when the managers of Tangzhishan Reservoir visited the reservoir area and walked near the waterside wetland, they noticed three swaying figures not far away, and initially judged that they were a deer-like animal of medium size. In order to further confirm, they adjusted the focal length of the camera, and observed through the lens that the body hair of the three animals was grayish brown, and there were two big ears on their heads, as if they were listening to the surrounding movements warily. The manager recognized this as a roe deer.

"The roe deer is a very interesting animal, which is more common in the northeast. It is really rare to see the wild roe deer in Beijing. Most of them live in sparse forest belts, usually active in river valleys and gentle slopes. Waterfront wetlands like Tangzhishan Reservoir are also one of their favorite environments. " The manager stopped, turned off the equipment that might make noise, and quietly observed in the same place: I saw a roe deer raising its front hoof, testing on the soft mud of the wetland, and curiously looking at the surrounding environment with big eyes. They jumped around in the grass and looked cute.

In recent years, the water ecological environment of Tangzhishan Reservoir is becoming more and more perfect, and the vegetation around the water area is becoming more and more lush, creating an ideal habitat for wild animals.(Reporter Yan Yingshuo)

　　　　Liberation Daily October 28th Recently, Russian President Vladimir Putin has become the focus of attention wherever he goes, which is inseparable from his core position on many hot issues in Europe, and on the other hand, it is closely related to his political fate that he is about to face a choice.

　　　　Profile photo: On October 12th, Russian President Vladimir Putin (right) met with visiting US Secretary of State Condoleezza Rice (middle) and US Secretary of Defense Gates (left) in Moscow. Putin suggested that the United States should not rush to implement the plan to deploy a missile defense system in Eastern Europe. Xinhua News Agency/AFP

　　　　New relations look forward to a new president.

　　　　The 20th EU-Russia Summit on 26th was not a success. Although both sides expressed satisfaction with their "constructive" attitudes and reached some consensus on energy and other issues, the differences in positions on many hot issues in Europe are still irreparable. In particular, the European-Russian Partnership and Cooperation Agreement signed by Russia and Europe in 1997 is about to expire on December 1 this year, and the "new partnership" that the two sides aim to establish has not even started negotiations. Ms. Waldner, Commissioner for Foreign Relations and Good Neighborhood Policy of the European Union, pointed out on 26th that the issue may not be resolved until the EU summit in May 2008 at the earliest.

　　　　It is not difficult to see from this deadline that the EU seems to prefer to discuss this issue after the Russian presidential election in March next year. In this regard, in addition to urging Europe and Russia to start negotiations on "new relations" as soon as possible, Putin also stressed in response to a reporter’s question that he has not finally decided whether to continue working in any field, but in any case, the current Russian government structure does not need any change, and he does not want to transfer the presidential power to the government.

　　　　Diplomatic strength adds chips

　　　　No matter at the EU-Russia summit on the 26th or during his previous trip to Germany and Iran, Putin continued to show his diplomatic strength, but this strength did not bring Russia the risk of falling into the "Cold War" again, but made the political chips in Russia’s hands more and more valuable.

　　　　In the EU-Russia Summit, Putin did not use any radical words to attack the US anti-missile deployment in Eastern Europe in view of his "constructive" stance and "moderate" attitude, but subtly compared this incident with the "Cuban missile crisis", thus attracting a "sensational effect" again.

　　　　Putin said at the press conference held after the EU-Russia summit that the Soviet Union had a similar behavior, deploying missiles in Cuba, which led to the "Caribbean crisis". He said: "The current situation is very similar in technology to that at that time. We have evacuated all the remaining bases in Vietnam and Cuba. But on our border, similar threats against China are emerging. " However, Putin immediately stressed that the United States is no longer an enemy of Russia, but a partner, and President Bush himself is his good friend.

　　　　The prospect of Russian election is concerned.

　　　　Over the past 10 years in power, Russia’s economic growth and the improvement of its great power have continuously consolidated Putin’s political status. When Putin came to power, he borrowed Peter the Great’s famous saying, "Give me 20 years and give you a miraculous Russia." Now that the time is just over half, it should be said that neither the people nor Putin himself will give up this dream easily.

　　　　From the current point of view, Putin will still be synonymous with "number one" in the hearts of domestic people. In this case, from songs praising Putin to judo teaching films featuring Putin, the propaganda about Putin’s personal charm is widely circulated among the Russian people and has far-reaching influence. Whether this is done intentionally to meet the needs of the election or not, the political effect it brings is not difficult to imagine.

　　　　At the same time, Putin obviously has the support of major Russian parties, as evidenced by his name appearing in the list of candidates for the Duma election of Russia’s largest party, the United Russia Party. In addition, veteran figures, including the Speaker of the Russian Federation, are trying to find a way to keep Putin as president after 2008 without violating the Constitution. It can be seen that whether Putin stays in office or holds power in other positions is no longer a "private matter" of Putin.

"In 2020, the operation of the machine tool industry was better than expected, showing a recovery growth trend." A few days ago, Mao Yufeng, executive vice chairman of cmtba, said that after nearly 10 years of downturn, the machine tool industry is welcoming new opportunities for development.

Machine tool, the machine that produces machines, is called "industrial mother machine" and is the core production base of equipment manufacturing industry. In the extraordinary year of 2020, the machine tool industry intensively cultivated and made many new breakthroughs in the field of high-end CNC machine tools: a major breakthrough was made in the super-large five-axis machine tool, and the world’s first 3D printing CNC machine tool with integrated casting, forging and milling was successfully developed …

During the "14th Five-Year Plan" period, how did the machine tool industry make up the short board and forge the long board?

Mid-to-high-end blossomed, and the machine tool industry showed signs of bottoming out.

In the spring of 2020, the machine tool industry reported good news frequently.

The first domestic high-speed five-axis machining center for ultra-long-distance high-speed rail developed by Shenyang Machine Tool of General Technology Group was successfully rolled off the assembly line. This machine tool is used for machining complex surfaces of large-scale structural parts of high-speed rail, marking the first time that domestic high-end CNC equipment is used for the production of core components in high-speed rail industry.

A month ago, the testing method of five-axis machine tool of "S specimen" revised by China officially became an international standard, and the machine tool people frankly said, "This is a hard bone."

"S specimen" is regarded as the "crown jewel" in the field of machine tool processing. As long as a machine tool can process qualified "S-specimen", then even complex thin-walled parts can be competent. The machining of "S-specimen" requires the machine tool to change various angles and ensure high machining accuracy.

"The core components of our machine tool have withstood the test of’ S specimen’." The person in charge of a leading machine tool enterprise in China said that it was a lot of suffering to break through the "S-specimen". "During the test, all the inspection points of machine tool processing were qualified, but the combined" S-specimen "always failed to meet the standard."

The reason is that there is still a gap in machining accuracy. Each inspection point should not only meet the standard, but also have almost zero error, so as to ensure that the error of the outline size of the "S specimen" does not exceed 0.05 mm. The R&D team of this enterprise keeps approaching zero error. After more than 1,200 tests, it finally chews this "hard bone" and realizes 100% qualified processing of "S specimen".

Mao Yufeng said that the localization of high-end machine tools in China is constantly improving. Up to now, the domestic market share of representative products such as domestic five-axis machining center and high-grade CNC system has increased to about 30%.

What is more gratifying is that not only the leading enterprises of large machine tools continue to conquer key technologies, but also the "invisible champion" in the segmentation field is breaking. In November 2020, nearly 20 enterprises in the machine tool industry were selected into the second batch of "Little Giant" enterprises publicized by the Ministry of Industry and Information Technology.

On January 4th, 2021, Shenzhen Genesis Machinery Co., Ltd. delivered another good news, and 218 T-V856s machine tools were shipped in a single day, setting a new high in recent years and winning a "good start". With reliable processing quality, the company has jumped to the forefront of subdivision in just over 10 years.

"In the past 10 years, the demand of China’s machine tool market has changed dramatically, from completely relying on investment to investment and consumption." Mao Yufeng said that in the past, the customers of machine tool enterprises were mainly concentrated in heavy industries such as energy, steel and equipment manufacturing. Now, customers have expanded into electronic products, new energy vehicles, medical devices and semiconductors. "Some enterprises that are not suitable for market demand have been eliminated, and a number of enterprises that respond quickly and focus on sub-sectors have grown rapidly."

Breakthroughs have been made at the high end and progress has been made at the middle end. The machine tool industry is gradually getting rid of the downward trend for many years, showing signs of bottoming out. According to the data of cmtba, in 2020, the total orders of metal processing machine tools increased by 16%.

Strengthen collaborative innovation and realize the expansion from 1 to 100 and from point to surface.

As an "industrial machine tool", the application scenes of machine tools are everywhere, ranging from small mobile phones, televisions and washing machines to large cars, high-speed trains, airplanes and rockets, and as fine as medical implants and medical devices, they are inseparable from machine tools. China’s economy is developing towards high quality, and the requirements for product quality and machine tools are getting higher and higher. "It can be said that the supply capacity and demand of domestic high-end machine tools do not match, not only the whole machine has a gap with imported machine tools, but also the key basic supporting parts." Mao Yufeng said.

Where is the gap? It lies in sustainable innovation based on application.

Zhu Kongfeng, deputy chief engineer of guangzhou cnc Equipment Co., Ltd. said that China has been able to produce high-end CNC system for machine tools, taking CNC system as an example, and achieved a breakthrough from 0 to 1. However, compared with imported high-end CNC systems, there is still a gap in technology maturity and brand influence. "It is these gaps that make it difficult for domestic CNC systems to expand from 1 to 100, from point to surface. At the same time, without the tempering of high-end application scenarios, the gap between domestic high-end CNC systems and foreign products will be difficult to make up, and even larger. "

"Good products are used. If no one uses them, there is no way to know the gap. There is no application scenario. How to upgrade the iteration?" Jiang Shilin, assistant to the chairman of Dalian Guangyang Science and Technology Group, felt that the high-end machine tool market is small in scale and high in unit price, and the price factor has little influence. "It is very difficult to develop domestic high-end CNC machine tools only by relying on enterprises themselves and market forces."

Mao Yufeng said frankly that for a long time, the prototype research and light application verification in the machine tool industry often means the completion of the project through the acceptance of the prototype. Few people pay attention to the follow-up application and market expansion of the products, and lack policy support for the promotion of innovative products of enterprises. This innovative model can only solve the problem of "being or not" and cannot meet the needs of high-quality development.

Faced with this dilemma, some enterprises have made useful explorations.

"We have advanced the time to find customers." Jiang Shilin said that in the past, products were sold to customers and they were asked to try them out. Now we come to the door first and ask our customers what their needs are, and the two sides research and develop together. "We understand the psychology that customers favor imported mature machine tools. After all, every failure and shutdown of the production line will cause huge losses. Therefore, we can only do our homework first. "

Recalling the first cooperation with a research institution, Jiang Shilin will never forget the more than 200 pages of A4 paper filled with questions. "The first joint research and development, customers asked us to use the standards for inspecting imported advanced equipment. For us, the problem paper with a thickness of 3 cm is not harsh, it is a baby. " Jiang Shilin recalled that after improving the equipment, the company sent engineers directly to the customer’s workshop to solve problems at any time, so as to improve the reliability of the equipment, the adaptability of the process and the stability of production, so as not to affect the performance of the operators and improve their enthusiasm for operating domestic equipment. After a joint research and development, Dalian Guangyang finally won the recognition of customers. The customer purchased 22 high-end five-axis machine tools at one time to form an intelligent production line. "After that, the company’s products opened up a situation in the aerospace field."

"The supply mode of the machine tool industry is changing from batch to customization, especially for mid-to high-end products. It is even more necessary for the machine tool industry to strengthen collaborative innovation practice with users, from passively following to solving user needs to jointly researching new needs and new processes." Mao Yufeng said.

Industry-University-Research actively embraced new technology with a game of chess.

Sharp tools make good work. For the manufacturing industry, this "device" is a machine tool. During the "Fourteenth Five-Year Plan" period, the machine tool industry has a long way to go to make up the short board and forge the long board.

"From the perspective of products, a good machine tool needs the quick march of the whole industry chain. The basic components determine the functional components, and the functional components determine the performance of the main engine. This is an interlocking process." Zhu Kongfeng said.

From the industry point of view, machine tools and a series of basic industries such as semiconductors, raw materials and cutting tools are interdependent and interdependent. For example, a high-end machine tool needs high-quality bearings, and high-quality bearings depend not only on the quality of steel, but also on the performance of the machine tool used to process bearings.

"This means that the machine tool industry needs to make up the shortcomings. It is not feasible to rely solely on the head enterprises, but it needs the user’s demand to lead and Industry-University-Research to use a game of chess." Jiang Shilin said.

Mao Yufeng emphasized that it is foreseeable that the demand for domestic high-end machine tools is expected to explode further during the 14 th Five-Year Plan period. In terms of major demand and common technology research and development, we need to explore how the new national system can play a better role.

Zhu Kongfeng said that, just as the "Proposal" of the Tenth Five-Year Plan proposed to implement the system of "revealing the list and taking the lead", he hoped that the relevant departments would guide the downstream enterprises to publicly release their needs and jointly research and develop with the upstream and downstream of basic industries and machine tool industry chains to form a new development pattern of complementarity, collaborative research and mutual promotion. "Government departments can adopt the way of purchasing services, with leading enterprises contracting related projects and organizing project participants by themselves to realize key core technologies.

"Although the machine tool industry accounts for less than 1% of GDP, it is the basis for upgrading the manufacturing industry to the middle and high end. To achieve high-quality development, the industry needs the strong support of more capital. " Mao Yufeng suggested that state-level large funds invest more in the machine tool industry, and at the same time give more opportunities to private enterprises. "After nearly 10 years of development in the machine tool industry, private enterprises have become an important force that cannot be ignored."

However, bury your head in the road and look up at the road. In recent years, subversive innovations in the machine tool industry have come out one after another, which not only makes up for the shortcomings of traditional CNC machine tools, but also affects the research and development ideas of traditional machine tools.

According to reports, the traditional CNC machine tools "do subtraction" in processing, and process mechanical parts by turning, milling, planing and grinding, which has the advantage of high reliability. 3D printing technology is "addition". First, liquid materials are solidified into planar thin layers, and then layers of thin layers are accumulated into the required three-dimensional objects, which is superior to controlling complex shapes. A few days ago, in Wuhan, a brand-new machine tool-casting-forging-milling integrated 3D printing CNC machine tool combined the advantages of the two.

"Many precision parts needed by modern industry have complex structures and extremely high requirements for precision and air tightness. Machining with traditional CNC machine tools is extremely difficult to control accuracy, while 3D printing technology has shortcomings in terms of air tightness. " Zhang Haiou, the project leader and a professor at Huazhong University of Science and Technology, said that the 3D printing CNC machine tool integrating casting, forging and milling combined their advantages into one, forging while casting, and successfully trial-produced the aircraft composite molding die only once, which not only met the requirements in parameters, but also overcame the bottleneck problems of difficult processing and low yield of complex large molds, and shortened the manufacturing cycle by at least 1/3.

"In order to meet the needs of efficient and flexible manufacturing, the transformation of traditional machine tools is imperative, which requires the machine tool industry to actively embrace new technologies and be ready to meet new challenges while practicing internal strength." Mao Yufeng said.

　　The organizer later explained that during the competition, the staff were reminded that court of arbitration for sports had previously stipulated that Russia was forbidden to use the Russian flag and national anthem in large-scale international competitions. In view of the fact that the game has already started, the staff of the World International Checkers Federation had to directly withdraw the items related to the Russian national symbol from the table. In addition, the staff explained that this was done because they might be sanctioned for this matter. In the end, the Russian player Tanskuzhina was defeated.

　　On December 17, 2020, court of arbitration for sports found that the Russian Anti-Doping Center violated the rules, and announced that Russian athletes could not represent their country in major international sports events including the Tokyo Olympic Games and the world championships of various events until December 16, 2022, but only participated in a neutral capacity, and were not allowed to use the Russian flag and national anthem.

　　Shark fright

　　Fifteen hours after falling into the sea, he met a more terrible underwater creature — — Sharks. "I thought it was barracuda at first, but later I found out it was a shark the size of a red bus in London." He said. "My first thought was ‘ It will eat me ’ 。”

　　Fortunately, archibald noticed that it was a reef shark, and it did not pose a threat to human beings.

　　Guangzhou Daily News According to the BBC, archibald, a South African man, escaped the serial attacks of seagulls and sharks after he fell into the sea on a stormy night in the Indian Ocean. He survived for 28 hours and was lucky to be rescued. Now, three years after the incident, archibald will still tremble when he goes to the seaside. However, he still called the sea a "happy place".

　　When Bu archibald fell into the sea on a stormy night in the Indian Ocean, he thought he would die. During the 28 hours he struggled alone at sea, he met a shark and was attacked by seagulls, but he survived. Recently, archibald told the media about his adventure of falling into the sea for the first time.

　　Survive by unique breaststroke

　　In April 2013, archibald, then 50 years old, and nine friends rented a boat to spend a holiday at sea near the Indonesian coast. In the early morning of 17th, there was a storm in the Indian Ocean, and archibald on the top deck was accidentally thrown into the sea. When he woke up, he had drifted 15 meters away from the ship. "I watched the lights of the boat disappear, and I screamed as hard as I could, but I soon realized that they would never hear my voice." He said. "I tried my best to swim, but I couldn’t catch the boat."

　　Watching the ship go further and further, archibald understood that he had to overcome all difficulties on his own. Archibald likes surfing and swimming, and he knows that he should take a deep breath to prevent the sudden waves from driving him to the bottom of the sea. A few hours later, his limbs began to cramp, and he could only repeat his favorite books and CDs in his mind to divert his attention.

　　Relying on the breaststroke method invented by himself, archibald kept his head floating on the water. But with the invasion of drowsiness, he fell asleep until the seagulls woke him up. "The seagulls pecked at my forehead, and I looked up to see what was attacking me, and the seagulls began pecking at my face," he said. "Blood started running down my nose, and I seemed to be hit by a baseball bat." Later, he drove away the two attackers.

　　After floating in the water for another 13 hours, archibald was finally discovered by his companions. At this time, he was 20 kilometers away from the place where he fell into the sea. After seeing that he didn’t have breakfast, his friends contacted the Indonesian Coast Guard and the surrounding ships and started the search and rescue work.

　　On the morning of 18th, a ship found archibald in the water. Miraculously, he is still alive, but his eyes are swollen and there is almost no blood on his feet, lips and hands.

　　After waking up, archibald said that it was his concern for his wife and two children that got him through this. (Linxi)

　　Five years ago, Nokia’s market share in a single quarter exceeded 40%, setting a new record. Apple 4S has not been released yet. Want to watch movies on the mobile network? You will be regarded as a madman … Nowadays, Nokia has been acquired by Microsoft, Apple has come out in 6S, and a brother named PLUS has been added. Watching movies on the mobile network has become a reality, and perhaps watching 100 movies in a month on the 4G network can also be a means to show off wealth.

　　All these changes have happened quietly in the past five years. Recently, the new word "internet plus" has appeared frequently in the public eye. You may not know the meaning of this word, but you can find its shadow in your life. It is changing our lifestyle and work habits, making our life more and more convenient, and many industries have generated endless magic because of it.

　　Broadband speed-up and price-reduction users are increasing day by day.

　　"internet plus" is inseparable from the support of the Internet. For this reason, the State Council has repeatedly urged all localities to reduce network fees and increase network speed. Since 2013, the three major operators of China Telecom, China Mobile and China Unicom have launched services to reduce Internet access charges and improve Internet access speed. In the past, we might have to wait a few hours to download a 2G movie. Now, it can be done in a few minutes at the earliest.

　　Xiao Yang is a game lover. In the past, downloading games and movies at night was once his "daily life", which was both electricity-consuming and noisy. "The aging computer chassis fan often made noise decibels like when a motorcycle started." Nowadays, the download speed in fttp has increased by leaps and bounds. "Now eat a meal and take a bath, the movie will be ready, and the computer will become docile because it doesn’t have to stay up late to work overtime." Xiao Yang told reporters.

　　According to the economic operation of the communication industry in September 2015 published on the website of the Ministry of Industry and Information Technology, the total number of broadband users with access rate of 8Mbps and above exceeded 128 million, accounting for 60.6% of the total number of broadband users. The total number of FTTH/0 users with optical fiber access reached 102 million, accounting for 48.3% of the total broadband users.

　　Optical fiber network enters rural farmers and turns into e-commerce talents.

　　Li Shun, a villager from Huangxing New Village, Changsha County, Changsha City, is sitting in front of a computer screen and banging on the keyboard. At present, the full coverage of optical fiber network is being implemented in rural areas. When the Internet entered the countryside, many farmers became large e-commerce companies.

　　"There are too many Taobao buyers consulted, and the business is particularly good this year." Li Shun said cheerfully.

　　Soon-jae Lee opened an online store in 2013 to sell its own farm products.

　　"In the past, dial-up Internet access was used in rural areas, and the network speed was not strong. Upload more pictures and get stuck. Sometimes, if you don’t reply to the buyer in time, you blow a business. " Li Shun revealed.

　　In March this year, the telecom staff took the initiative to provide on-site service to upgrade the optical fiber network for the villagers in Huangxing New Village free of charge. Li Shunjia’s internet speed has increased to 50M, but the monthly fee has not changed.

　　"After the network speed has been greatly improved, the online shop page has been updated, the pictures are clearer, and the services such as consultation and payment are very smooth, and the business will no longer be affected by the network speed." Li Shun introduced that there were more than 300 orders a day this year, and more than 30,000 zongzi were sold on the Dragon Boat Festival. In the first half of the year, Li Shun’s sales reached 2 million yuan.

　　Online shopping drives the express delivery industry anytime and anywhere.

　　Now, shopping through the Internet is nothing new. Everything from clothes and home appliances to cars and houses can be bought easily and quickly through the Internet. With the upgrade of mobile Internet speed, the way of online shopping has also changed. With the emergence of 3G and 4G mobile phones in recent years, many online shoppers have fallen in love with "mobile shopping". Whether watching TV at home or on the bus to and from work, they use their mobile phones to select goods online as long as they have spare time.

　　The popularity of online shopping has also driven the development of express delivery industry. The courier brother who shuttles through the streets has become a landscape in this city. According to Ma Junsheng, director of the State Post Bureau, China’s express delivery industry is developing rapidly. In 2015, the total express delivery business is expected to reach 20 billion pieces, an increase of eight times compared with the initial period of the Twelfth Five-Year Plan. The scale of express delivery continues to expand, the service level continues to improve, and the number of enterprises has also increased significantly.

　　It’s no trouble to eat, live and travel. A mobile phone is all fun.

　　"internet plus" is deeply rooted in catering, travel, accommodation, movies and other life service industries. A smart phone can do everything for you. In the past, when we opened a restaurant, we only needed to open the door to welcome guests, and consumers would come to eat. Now, even if you are open 24 hours a day, you may not have many customers. Ordering apps such as Hungry, Baidu Takeaway, and Home Food Party have mushroomed.

　　A few years ago, when you went to the cinema, scalpers often sold you movie tickets. Now the scalpers in the cinema have disappeared and there are many ticket machines. People buy tickets through the internet, and then go to the ticket machine in the cinema to get tickets directly, which is not only cheap, but also saves a lot of trouble in queuing to buy tickets. The scalper was forced to change careers. Maybe it was him who sold popcorn at the entrance of the cinema.
