2.0T small steel cannon, brand-new 2023 Volkswagen Golf GTI launched.

Text/Theseus

Volkswagen is a world-famous manufacturer, and its global sales volume is second only to Toyota, ranking second in the world. In the domestic automobile market, Volkswagen is also very popular and has a good sales volume. Volkswagen has been developing in China for 40 years, which has established a good brand image in the hearts of consumers and has also become the benchmark of automobile brands. As a classic model of Volkswagen, Volkswagen Golf has been loved by young consumers for many years with its fashionable appearance and excellent mechanical quality. Golf GTI, as the top model of golf series, has outstanding performance and is known as a small steel gun, which is pursued by young consumers. Recently, FAW-Volkswagen announced the official launch of a brand-new golf GTI model, which is equipped with a better power system and a more fashionable and sporty appearance. The guide price is 229,800 yuan.

[Cheyou Headline-CheyouNo.-Zhidian Automobile]  

In terms of appearance, GTI is obviously more refined in appearance than ordinary golf. Adopt flat front design, through design, and the addition of red decorative strips highlights personality and movement, which is full of movement. Large-size air intake grille with blackened honeycomb structure inside brings brand-new visual impact and looks more sporty and domineering. In addition, the brand-new GTI adopts the brand-new LED headlight group design, which looks sharper and improves the aggressiveness of the whole vehicle, while the word GTI is also located at the left headlight corner, which instantly improves the advanced feeling of the whole vehicle.

The side of the car body is not much different from the ordinary version. The integral side skirt design makes the car body lower. The side lines of the vehicle are smooth and concise, and the classic body shape is still dynamic, but the latest 17-inch sports aluminum alloy wheels are added, which adds a sporty atmosphere. The lower part of the door and the rearview mirror shell are decorated with silver, which enhances the luxury of the vehicle.

At the tail, the tail design of the new golf GTI is very special, with distinct layers, and the integrated body shape design is selected. The taillights are more sharp, and the rear spoiler is large, with black surrounding at the top and bottom and double exhaust at both sides, showing the demeanor of a high-performance car.

When it comes to the interior, Golf GTI still adopts the ordinary version of golf design style. The center console design is almost the same as that of golf. The embracing center console that is biased towards the cab design adds a sense of movement with GTI’s exclusive red control interface. The perforated leather material and the fur cover of the seat make people feel comfortable and can reflect the luxury inside the car. The brand-new 10.25-inch LCD instrument panel, central control suspension screen and three-position multi-function steering wheel design reduce a lot of physical buttons and improve the sense of science and technology in the car. The GTI version adopts a new integrated sports plaid seat to provide better support and comfort. In terms of configuration, the new car is equipped with 30-color ambient lights, reversing images, constant-speed cruise, multiple driving modes, automatic parking, uphill assistance, variable steering ratio, electric sunroof, keyless entry and start, remote start, low-speed driving warning, active noise reduction, 8-speaker speakers, automatic air conditioning and so on. The main and passenger seats are equipped with airbags, front and rear head air curtains, knee airbags, passive pedestrian protection, tire pressure alarm, fatigue driving tips, etc. The new golf GTI can enjoy the blind spot image on the side of the car, the openable panoramic sunroof, leather seats, front seat heating and so on. From the configuration of golf GTI, a variety of intelligent configurations make consumers more convenient and worry-free.

In terms of power, as a small steel gun, its power performance is naturally the most concerned by everyone. The new car is equipped with a 2.0T engine, with a maximum power of 162kw, a maximum horsepower of 220 horsepower and a peak torque of 350 Nm. With the DQ381 7-speed wet dual-clutch gearbox, the speed-up time of 100 kilometers is only 7.2 seconds. It can be seen that the performance of this new car is very strong. In terms of chassis, the new Golf GTI has also updated the subframe, reinforced bearing, front double wishbone suspension stabilizer, front six-piston brake system and ceramic front brake disc, and the ground clearance of the chassis is reduced by 25mm compared with the ordinary version of golf. It is equipped with suspension system, brand-new shock absorber and valve system, which are unique to the new golf GTI, improving the driving quality and meeting the performance needs of young people.

Write at the end:

The appearance of the 2023 Volkswagen Golf GTI has attracted the attention and heated discussion of the majority of riders. Its strong performance, sporty appearance and interior design, high-quality driving experience and other aspects show its strong quality. The new Volkswagen Golf GTI not only continues the excellent tradition in the past, but also injects more innovation and high-tech configuration, making it a good choice for young consumers.

How many of these technologies from NASA have you seen?

  Today viewpoint

  Aerospace gives people a special feeling of "high cold", which reminds them of advanced fighter planes and magnificent space stations that ordinary people can’t see, touch or use.

  A few days ago, the well-known American website "GOBankingRates" took stock of 25 kinds of technologies originated from the National Aeronautics and Space Administration (NASA) in our daily life, which spread all over our "food, clothing, housing and transportation". They come from the distant sky, but they are convenient for our daily life.

  Food: baby milk powder, freeze-dried fruit, food safety packaging.

  At present, more than 90% of infant formula in the United States contains microalgae. It was originally the product of NASA research, the purpose of which was to test the potential use of algae as an oxygen "recycling agent" in space travel.

  Freeze-dried fruit is a common snack. However, the purpose of NASA’s development of freeze-drying technology is to make the fruits in the Apollo mission easier to carry, and this technology can maintain 98% nutrition with 20% quality.

  In order to ensure the safety and quality control method of space flight food development, NASA has now become a food industry standard to protect the food safety of consumers all over the world.

  Life: memory foam mattress, scratch-resistant lenses, anti-ultraviolet sunglasses, cordless vacuum cleaner, Nike air-cushion sports shoes, space blankets, ski boots.

  Comfortable memory foam mattress can fully fit the human body and relieve stress, which is necessary for many families. Memorable foam was not originally used to make mattresses. It was originally developed by NASA to cushion the impact of spacecraft landing on astronauts.

  Compared with ordinary glass, scratch-resistant lenses have a longer life. In fact, the scratch-resistant coating is a "by-product" accidentally discovered by Jet Propulsion Laboratory (JPL) under NASA when researching the diamond hard coating for aerospace.

  In 1980s, two scientists from JPL developed a kind of welding glasses, which can absorb, filter and scatter the strong light emitted during welding. Later, this technology was widely used in anti-ultraviolet sunglasses.

  Initially, Black&Decker was ordered to develop a portable device for Apollo and Gemini missions, which was used to extract samples from below the surface of the moon. This technology has been improved to become a "cordless vacuum cleaner".

  Nike air-cushioned sneakers use the patent of "Blow Rubber Molding" obtained by M. Frank Rudy, a former engineer of NASA. The initial application target of this technology is spacesuit.

  The space blanket is insulated and heat-preserved, which is an essential item for survival in the wild and marathon. But it was originally developed by NASA to protect spacecraft and astronauts at low temperatures.

  In addition, the technology used by NASA in the joints of spacesuits has been improved and used in ski boots, which improves the athletes’ control ability in skiing.

  Home: swimming pool purification system, household heat insulation materials.

  In order to resist the extremely low space temperature, NASA made an insulating material called "radiation barrier" from aluminized polyester. According to JPL, aluminized polyester is now used in most household insulation materials.

  In 1960s, NASA developed an electrolytic silver iodide filter to provide clean drinking water for astronauts, and now it is widely used to purify swimming pools.

  Travel: aircraft deicing system, precision GPS, anti-skid groove on highway, better tires.

  According to NASA’s technology transfer plan, civil aircraft can fly in cold weather, mainly due to a thermoelectric deicing system called Thermawing developed by NASA.

  Many mobile phones are equipped with precision GPS technology developed by JPL, and its data comes from JPL global GPS receiver network. Even if there is no wireless connection, you can still use GPS positioning on your mobile phone.

  NASA’s Langley Research Center has developed anti-skid slot technology to prevent aircraft accidents on wet runways. Later, this technology was widely used in expressways.

  In 1970s, Goodyear Company developed a new tire material for NASA Viking Mars probe, which was used in parachute system. This technology was later used to improve ordinary tires, increasing their life by 10,000 miles.

  Electronic products: mobile phone camera, notebook computer, high-power solar cell, wireless headset, mouse, CAT scanner.

  In the 1990s, NASA asked JPL scientists to make a miniature camera that can be installed on spacecraft while ensuring the quality of photography. According to JPL, one-third of mobile phone cameras now use this technology.

  According to the Smithsonian National Air and Space Museum, "Grid Compass" is the first notebook computer in the world. It was first used in the space shuttle mission in 1983, which is one of the inventions of NASA.

  The crystalline silicon solar cells used in the home originally came from the lightweight solar energy system developed by the Environmental Research Aircraft and Sensor Technology Alliance under NASA for electric aircraft.

  NASA has developed wireless headphones for astronauts to facilitate their communication. Now this technology has entered thousands of households.

  According to JPL, a NASA researcher developed a computer mouse in the 1960s, which allowed users to operate on the computer screen and made the computer more interactive.

  JPL initially developed a CAT scanner to scan aerospace components to get advanced digital images to detect defects. Now, it has become a commonly used medical instrument.

  Medical care: cochlear implant, invisible dental appliance, ear temperature thermometer.

  Adam Kiser, an engineer at Kennedy Space Center, used his working experience in electronic, sound and vibration sensor systems in the space shuttle project to develop early cochlear implants by using electric pulses instead of sound amplification technology.

  Compared with the traditional metal appliance, the invisible dental appliance is more beautiful. It is made of transparent polycrystalline alumina, which was originally developed by NASA to track heat-seeking missiles.

  Nowadays, many parents use ear thermometer to measure the temperature of sick babies or young children. According to JPL, this thermometer adopts infrared dissection technology invented by NASA and Diatek.

  There is always one of these 25 technologies that you have seen, touched and used. Aerospace technology can not only be used in high space, but also improve our quality of life after landing, which is one of the driving forces for human beings to explore and fly higher and farther.

A small-scale "world war"! Deeply reveal why the Syrian crisis can’t stop.

       CCTV News:In Syria, this crisis full of pain and destruction has begun to enter its eighth year. From Dongguta to Aflin, from "politicization of humanitarianism" to successive "threats of chemical weapons", these chaos and the wrestling behind the great powers have become the epitome of the chaotic situation in Syria. So, where did this crisis come from? Why has it lasted for seven years and still can’t stop?

       Time has entered 2018, and the Syrian crisis situation that lasted for seven years has not become clearer.

       The conflict in Dongguta, the re-emergence of humanitarian problems and the self-talk of relevant countries have once again shattered the hope of peace that was ignited by the exit of extremist organizations.

       Not only Dongguta, but also Russian and Israeli warplanes were shot down in succession. The anti-terrorist coalition led by the United States clashed with pro-government forces in Deir ez-Zor, and Turkey launched the "Olive Branch Action" against Kurdish armed forces in northern Syria — — The situation in Syria is more foggy than ever.

       Huntington, an American political scientist, in his book The Clash of Civilizations and the Reconstruction of World Order, divided the "fault line war of civilizations" into three levels: the parties actually fighting and killing each other, the countries directly related to the main participants, and the top core countries — — If the top countries have no intention to end the war, the conflict will continue.

       In fact, the Syrian crisis basically conforms to this theory: if the participants are divided into three levels, the extremist organizations that have lost their momentum only belong to the lowest level, that is, one that fights and kills each other, including the Syrian government, Hezbollah in Lebanon, opposition armed forces, the terrorist organization "Conquest Front" and the "Syrian Democratic Army" led by Kurdish armed forces.

       Above the hierarchy of factions on the ground, there are neighboring countries, including Iran, Turkey, Israel, Saudi Arabia and other Gulf countries. Most of them directly participated in the chaos in Syria and promoted the development of the situation.

       However, although it has great influence on the situation in Syria, the surrounding stakeholders can’t influence the final situation in Syria, because at the top, there is a game between Russia and the United States, two world powers.

       At present, Russia has announced that it has begun to withdraw its troops from Syria, and at the same time, it has promoted several dialogue platforms such as Astana and Sochi in an attempt to solve the Syrian issue as soon as possible. However, the attitude of the United States on the Syrian issue is extremely vague. It has established the so-called "border protection force", set up as many as 20 military strongholds, refused to participate in the Russian dialogue platform, and constantly created obstacles for the political settlement of the Syrian issue on the grounds of human rights and chemical weapons.

       There are more than ten participants in the Syrian crisis, and there is also a decisive factor in the absence of the United States. What is more complicated is that the contradictions contained in the Syrian crisis are also different.

       At the end of 2010, the so-called "Arab Spring" swept across the Middle East and North Africa. Since Tunisia, many countries such as Libya, Egypt and Yemen have experienced chaos.

       In March 2011, protests broke out in Syria.

       At the beginning, the main contradiction in Syria was the stay of President Bashar and the reform of the government. However, because of the interests, the protests in those years were used by many parties, including western countries. After seven years of conflict, ethnic contradictions, religious contradictions and sectarian contradictions have already evolved. From the Kurdish autonomy movement to the rise of Islamic fundamentalism in Syria, to the sectarian dispute between Sunni and Shia, the situation has developed beyond everyone’s expectations.

       It is extremely difficult to completely solve any of the above contradictions, coupled with the attempts of many countries in the Middle East to intervene in the Syrian crisis to achieve regional hegemony, the historical grievances caused by the Palestinian-Israeli issue and the Israeli occupation of the Syrian Golan Heights, the refugee tide caused by the Syrian crisis, and the rampant terrorism and extremism in the 21st century — — The Syrian crisis has concentrated most of the major contradictions of mankind for centuries, so it has become a small-scale "world war" after its outbreak.

       Xu Dezhi, a CCTV reporter, said that it is almost impossible for more than a dozen crisis participants to solve at the same time, or at least cool down so many contradictions and sort out the intertwined interests, which is the fundamental reason why, up to now, although many parties are calling for a political solution to the Syrian issue as soon as possible, it still has little effect. Igniting the fuse of war is very simple, but ending a war is beyond people’s control.

"CyberChina" is popular outside the network! Chongqing night scenes and cars look foolish. Foreign netizens: Do China people live in 2050?

To say that China is the hottest city on the Internet recently, Chongqing must be on the TOP 1 list.

The Title of "8D City" has gone overseas, and the subway can go through the wall, and you can’t tell which floor you are in. The surreal magical cyber night scene has become the "Three tales of mystery in Chongqing" in the eyes of foreign friends.

Let the American little brother dream, let the little sisters in Europe feel excited, Chongqing has been included in the future fantasy list of contemporary young people:

"I was shocked into aphasia, and it felt like time had traveled to 2050."

"I just went there last year and was completely impressed. Being in it is like reaching the future 100 years later. It’s a great city."

"Spider-Man went crazy in Chongqing."

Of course, the sense of Cyberpunk in China city is just one of the topics that have exploded on the Internet. Speaking of playing with Cyberpunk’s sense of the future, we are all used to new energy technology and intelligent driving, and foreign netizens were shocked when they saw it.

Just brush the video of the external network. Under the content of introducing China’s new energy, foreign netizens are basically shocked by "never seeing the world":

"Can you buy it in America? This car looks more upscale than all our cars here."

"The United States will never let such a China car enter the market, and once it rushes into the United States, it will surely kill similar competing products."

"China car, best car."

Even the car navigation can predict that the red light will end in a few seconds, which is a function that everyone in China uses and takes for granted, and it can make them stunned on the spot.

"It’s cool to predict the red light by car navigation! I feel that our country has been left far behind. "

"Can traffic lights be linked with in-car navigation?"

It’s no wonder that the car ideas of foreign netizens still stay in the last century. After all, our country’s sense of existence in the global new energy field has reached the point of "terror".

For ordinary people in China, not only is the proportion of taking taxis to new energy vehicles swishing upward, but the recruitment of new energy enterprises is striding forward in the public opinion field. If you pay attention to the choices of people around you when buying a car, you will find that new energy vehicles, which were once ignored, have now become the first choice of many basin friends.

In their words, it is-"I used to look down on new energy vehicles, but now I am the first to shout".

It is no exaggeration to say that China’s new energy is not just a "rise", but now the general trend is that China’s new energy has gone overseas to "beat up" the world and make up for the lost share in the automobile industry for decades.

How strong is this momentum? Even the traditional car-making powers have a sense of crisis.

Fortune magazine just reported last Sunday that China’s electric vehicles attacked the city overseas, forcing German auto parts manufacturers to change their thinking: "We must adapt to the trend of making cars in China in order to survive."

(Holger Klein, CEO of German auto parts manufacturing giant ZF)

Germans’ worries are not unreasonable. According to the investigation report of Allianz, Germany’s largest financial group, if China’s new energy vehicles continue to develop, by 2030, the total annual net profit loss of European automakers will exceed 7 billion euros (about 54.6 billion yuan).

This figure made them "panic". After all, the sales of European cars are not as good as before, while the sales of local cars in China have been increasing, which has squeezed the living space of European car companies in China.

Now, coupled with the fact that we have finished building cars and exported them to Europe, and rolled them up to Europe at home, we have taken a two-pronged approach, so that comfortable Europeans really feel the cold winter of sales.

(The sales of new energy vehicles in China broke out in the decade from 2011 to 2021, from visualcapitalist)

In addition to the panicked Germans, Japan, another car-making power, could not stand it. Japanese cars also showed signs of "crash" in China, and Japanese experts began to spread anxiety, saying that China had entered a new era ahead of schedule.

According to them, for every four new energy vehicles sold in the world, one of them is from China. In Norway, the number of new cars sold by China New Energy accounts for 79.3% of the total market. Japanese experts sighed greatly: our Japanese car got up early, and now it’s late.

Why did Germany and Japan, a car-making power, suddenly feel a sense of crisis?If we carefully study the export data of new energy vehicles in China, we will find that the brand represented by MAXUS, SAIC Datong, has gradually taught foreign friends over the past few years what is called dimension reduction.

In terms of sales volume, in the wave of China’s new energy export overseas,The cumulative sales volume of SAIC MAXUS in overseas markets in 73 countries and regions has exceeded 300,000 units, and it has become the top stream in developed markets such as Australia, New Zealand, Britain and Norway, accounting for more than 80% of the sales volume.

With the hard power of "All-around Hexagon Warrior", foreign traditional brands of fuel vehicles can no longer stand on the same starting line with us.

From the price point of view, while maintaining the same quality at home and abroad, SAIC Chase MAXUS has successfully played a high premium in overseas markets.

Take TESCO, which has opened stores all over the streets in Britain, as one of the three largest retail enterprises in the world, TESCO has purchased 150 sets of MAXUS pure electric light passenger EV90 refrigerated trucks.

You know, in Britain, the price of new energy products such as pure electric light passenger EV90 has been higher than that of Renault in France, and the sword refers to Mercedes-Benz. Although the domestic price is nearly doubled, SAIC Chase MAXUS still won the order with the strength matching the pricing.

What is even more amazing is that when these cars were delivered, they also created the largest air transport record of electric light commercial vehicles in the world.

TESCO chose air transportation to let SAIC Chase MAXUS send the car to the UK. The freight is more expensive than the goods themselves, which shows how much you want to pick up the car. It is really a two-way trip.

Reliable plus high-end, high premium can also take orders. The more you know about SAIC MAXUS, the more developed countries with long-term cooperation are interested in the brand itself, and the more willing they are to award a wave of industry awards to SAIC MAXUS.

After the British bought it from MAXUS, SAIC Chase, in buy buy, they put the Green Fleet for six consecutive years.(New Energy Vehicle Enterprise Award)The honor of "Electric Vehicle Manufacturer of the Year" was awarded to SAIC Chase MAXUS, and the days when Japanese car companies in Europe, America and Japan once monopolized the awards have become a thing of the past.

Last August, SAIC MAXUS also won one of the most authoritative automobile awards in the world, the "Automobile Innovation Award" in Germany.

This year’s SAIC Chase MAXUS is still like chopping melons and vegetables, and it won the best new energy brand award of the year by autocosmos, the authoritative automobile media in Chile, the "best van 2023" by Businessvan, the preferred strategy website of British container trucks, and the best design model award of Havana Industrial Fair in Cuba in 2023. …

Behind the world’s soft hand in winning prizes, high quality and high premium, it is the cultivation of SAIC Chase MAXUS’s "two blossoms":

On the one hand, it is the hard work of the new energy technology system, on the other hand, it is the foresight of the strategic layout.

Take MIFA 9, the first full-size pure electric luxury intelligent MPV that landed in Europe, as the flagship model facing the global market, positioning the high-end "global hard currency" in environmental protection, technology, comfort and other aspects, which shocked foreign friends with high product strength from the East.

(MIFA 9 unveiled at Birmingham Motor Show, UK)

The early deployment of new energy MPV products has also made MIFA 9 shine in overseas markets and take the lead in stabilizing the high-end.

Now we can see that the results of cultivation have spread all over the world, all over the industry and all fields.

In the logistics industry, SAIC Chase MAXUS won the reputation of "handing the king’s car".SAIC Chase MAXUS light passenger pure electric light passenger EV series stands out among the "picky" car selection standards in developed countries, and postal systems in Ireland, Belgium, Australia and other places have been praised and repurchased.

The logistics team of DPD, the second largest logistics group in Europe, in the UK also heard the news, and signed the largest single order of China brand light passenger car overseas with SAIC Chase MAXUS, which also set a new record for the largest single order of China automobile brand in the UK.

In the chemical industry, T90 EV, a pure electric pickup recognized by the Ministry of Communications of New Zealand at the national level, has also attracted the attention of Chilean lithium mining giant SQM.

Lucky, energy-saving, smart and easy to drive, this car has officially settled in the largest chemical enterprise in Chile.

It can be seen that SAIC Chase MAXUS and other domestic cars have appeared all over the world and in all fields. In the past, I only felt that domestic new energy sources were making progress, but I really didn’t think about the extent of progress. However, judging from the explosive development trend this year and the real data at hand, we have reached this step that can lead the global industry reform.

Once in the era when fuel vehicles occupied an absolute dominant position, our country could not get the core technology, and it was always suppressed by the first superior. Nowadays, generations of technology cultivation and accumulation in the field of new energy have finally ushered in the time of flowering and fruition.

The domestic new energy brand represented by MAXUS, SAIC Datong, has done things silently and made a blockbuster. With the spirit of hard work and steady progress, it has been exported overseas and staged an over-burning reversal.

Looking at today’s new energy field, we have undoubtedly stood on the cusp of a new era.

In the new era, SAIC Chase MAXUS has stood firm at the high end. The road to the future has never been smoother.

When the ping-pong ball is hit at supersonic speed …

In animation, Japanese students usually have the power of conan the destroyer, and playing ball always feels like a high-tech war.
In reality, can humans play ball games so ferociously?
(All the articles are professional, please don’t imitate them at home.)
Although it is impossible to rely on manpower, we can use the power of air and machines, such as the "vacuum table tennis cannon."
A cannon is actually more like a pipe. When a cannon is fired, the speed of the accelerated table tennis can reach 450km/h, which is about one third of the speed of sound.
At this time, the table tennis directly crashed into the coke with air pressure, and this can was like a punch in the abdomen:
What if the speed of table tennis is increased to supersonic speed? Will it be more powerful? In fact, mythbusters, a well-known popular science team, made a similar attempt many years ago.
According to their test, the average adult can hit the ball at a speed of about 112.6 kilometers per hour after swinging.The speed of sound is 1224 kilometers per hour, which is an insurmountable gap.
Unless, of course, the table tennis player is a machine.
After several attempts, they successfully increased the speed of table tennis to 730 kilometers per hour by pressure jet, which directly penetrated the 2.5 cm cardboard, but this speed is still far from the speed of sound.
At this time, the "vacuum ping-pong cannon" appeared.
To put it simply, this device is to put a ping-pong ball at one end of a pipe and then seal both ends of the pipe:
Then, the air in the pipeline is drained to make it enter a vacuum state, and then the seal at one end is punctured, and the air will rush in wildly and then fill the vacuum space.
At this time, the table tennis in the middle will be pushed by the air and move to the other side at high speed, and there is no air obstacle on the road.
The power of this kind of vacuum cannon has been improved remarkably. With only a 1.8-meter-long pipe, the ejection speed of table tennis has reached 600 kilometers per hour.
And if we add a pressure chamber to the vacuum cannon and increase the length of the barrel, the speed will be upgraded again.
(Image from Purdue University of Technology)
But it is not as long as possible. Once the barrel was lengthened to 47 meters:
The acceleration effect is different. After firing, the human eye can’t see the ball moving at all, and the ball disappears directly:
However, when the table tennis flies out of the barrel, it has been squeezed out of the ball by resistance.
In the end, the barrel was reserved for 6 meters, which not only ensured the integrity of the ball, but also reached the speed of 1770 kilometers per hour, which properly exceeded the speed of sound.
So, "What destructive power will the vacuum table tennis cannon have now?The researchers set the shooting target-a thick pig elbow.
Fill in table tennis, adjust the pressure, pump out the air and fire!
Table tennis hit the surface of the pork completely, and the elbow suffered great damage. A round wound immediately appeared on the epidermis:
But the injury doesn’t stop there. Under this wound, there is a wound with a depth of nearly 4 cm:
However, this wave of injuries is difficult to subdivide how much table tennis can account for. After all, it broke at the moment it touched pork, and the subsequent injuries were more like air cannons.
But overall, it smells like animation.
There are still many people who use "table tennis vacuum cannons" to sabotage. They have chosen all kinds of strange targets for testing.
Mark French, a professor at Purdue Institute of Technology, and his students, combined a supersonic table tennis cannon with a pressure chamber and a vacuum gun, which is said to be faster than an F-16 fighter.
(All the articles are professional, please don’t imitate them at home.)
In the face of this kind of attack, the table tennis bat can do nothing at all and is directly penetrated:
When you hit a tape, it’s like hitting tofu:
Not only did the tape break a hole, but the carton at the back also broke a hole:
Carton:
The most cruel thing is to play a row of cans and disappear in an instant:
Look at the injury of cans, it should be destroyed by the group:
With such destructive power, it is no wonder that the professor emphasized on the whiteboard that he is a professional team and advised others not to try it at home.
Bruce Yeany, a physics teacher, also tried to play cans. From the effect point of view, he used more power:
But when he bombarded the watermelon, he encountered a problem, that is, the quality of table tennis was too small after all, and it broke directly in front of the watermelon:
Is this the only survivor in the table tennis test?
However, watermelon didn’t laugh for long. The teacher unhurriedly increased the weight of table tennis, not much, just filled it with water:

Top health care for adults: exercise

Text | Rotating Sunshine (rich book author)

For adults, exercise is the most cost-effective way to keep fit.

At the end of December 2021, Yuan Jingtian, a 40-year-old rice expert in Sanya, passed away due to illness.

When we feel sorry for expert Yuan, we should also realize the importance of keeping healthy.

I remember reading such a passage:

"We can’t control whether the future is rich or poor, when the cause will develop, and how others evaluate us.

But at least we can control our bodies and keep them in the best condition. "

Health preservation is a magic weapon to maintain the best state of the body. For adults, exercise is the most cost-effective way to keep fit.

Insisting on taking exercise as the top regimen is a homework that we need to work hard to do.

  • Exercise gives back to our state of physical and mental health.

Writer Liu Na wrote in "Flowers in Leisure":

"Whether it is a better job, a better company, and a better move forward, we need to give our physical and mental batteries full of energy."

Exercise, like a battery that charges our body and mind, can make us have a healthy body and a good mental state.

Academician Zhong Nanshan, who is over 80 years old, is still fighting in the front line when the epidemic in COVID-19 is raging, maintaining high-intensity work, relying not only on deep scientific research reserves, but also on a strong body.

Zhong Lao’s good state benefits from persistent exercise. In the past few decades, he has exercised at least three times a week for more than an hour each time, which has become his unshakable habit.

Grandpa Zhong Nanshan said, "Exercise plays a key role in my health. The length of life, mostly does not depend on aging and disease, but a normal lifestyle.

Nowadays, it is precisely because many young people have not developed a correct lifestyle that various diseases will appear in their bodies and their organs will age faster. "

The sweat we shed for sports will one day be returned to us with a strong body and a good mental state.

At the same time,Whether it is to drive away confusion or to fight anxiety, exercise is one of the simplest and most practical methods.

Sammi Cheng, a female star, once suffered from severe depression. For a time, she overeated, resulting in a completely out of shape.

She is also getting more and more anxious, and her body and mind are on the verge of collapse.

In order to get rid of her bad state and restore her body and mind to a healthy level, she followed the doctor’s advice and began to try moderate exercise.

She started running for eight kilometers every day, and she persisted for more than ten years.

Although she is nearly 50 years old now, she is still well-proportioned and full of energy, which vividly explains the story that "time never defeats beauty".

Insisting on exercise will make us have a state of good physical and mental health, so that we can calmly resist the traces of time.

The stage of a person’s life is not in the eyes of others, but in his own heart.

We insist on sports, not to win applause from others, but to broaden the length of our lives and the width of our hearts.

  • Exercise can help us form the habit of self-discipline.

Russian educator ushinski said: "Good habits are the capital that people store in the nervous system. This capital will continue to grow, and a person can enjoy its interest all his life."

Exercise can help us form the habit of self-discipline, so as to salvage more light and hope in life.

The writer Haruki Murakami has been running for at least one hour every day since 1982.

In the book "What Do I Talk about When I Run", he recorded his running mood for 36 years and his daily feelings.

It takes a lot of perseverance to insist on exercise, but Haruki Murakami thinks, "I don’t want to run today, so I just run. This is the way of thinking of long-distance runners."

He gets up at 4 o’clock every day, writes for 5 hours, runs for 1 hour or swims for 1.5 hours in the afternoon, then reads and listens to music, and goes to bed at 9 o’clock in the evening. Whenever I started writing a novel, this routine never changed.

To outsiders, Murakami’s writing life is a bit rigid, like a Swiss mechanical watch, and every minute is not bad.

But Haruki Murakami himself knows that this habit of self-discipline has benefited him a lot.

Writer Haruki Murakami wrote in his autobiographical novel: "For more than 30 years, I have never felt that writing is a hard job, and I have never encountered a low tide."

Insisting on exercise has helped him form the habit of self-discipline. He moved the habit of self-discipline into his creation, thus gaining a reputation in the literary world.

Although for most of us, even if we persist in exercise, it will not change our lives dramatically, and we will still be anonymous in the vast sea of people.

But insisting on exercise and getting up early will make us change subtly:

Netease Cloud once had such a hot comment: "In fact, you can get up early instead of staying up late. The world is still sleeping, parents are still sleeping, the boss is sleeping and the teacher is sleeping;

The whole world is still sleeping, so you can watch the sun rise slowly and feel that the light will always come;

The people you care about will wake up slowly, the world is still moving slowly, and you will still have your own time. "

Persisting in exercise and getting up early will give us a brand-new state to treat life, thus continuing to write about beauty in ordinary daily life. This is also the compound interest effect of self-discipline.

Because time knows, there has never been any life, only a lot of accumulation.

  • Exercise can make us more resilient.

Angela duckworth, an American psychology professor, through the study of West Point Military Academy, came to the conclusion that:

"The core element of a person’s success is not IQ, EQ, family background, or so-called test scores, but the person’s psychological resilience, or anti-vulnerability. "

Sports is a powerful weapon to exercise our psychological resilience.

Because many sports have their own competitive characteristics. As long as you participate in sports competitions, you will win or lose.

If you participate in sports regularly, you won’t care about winning or losing for a while, thus making people more resilient.

In his New Year’s Eve speech in 2022, Luo Zhenyu talked about one thing that he went to see 60-year-old Yu Minhong:

"I asked him, do you exercise at ordinary times? He immediately got up and did 10 push-ups, which made me dumbfounded.

What I envy is not only his body, but his energy. New Oriental’s education and training business was frustrated, but it’s okay. People started all over again and worked on agricultural products. "

Yu Minhong, 60, can get up immediately and do 10 push-ups, which means that he should spend a lot of time on exercise.

In fact, Yu Minhong has always attached great importance to sports. He once advocated in his speech that "every child should practice at least one sport."

As we all know, Yu Minhong is a very resilient person:

He was admitted to the university only after three college entrance examinations, and he also experienced various hardships in the process of starting a business in New Oriental.

In 2021, due to the implementation of the national "double reduction" policy, Yu Minhong’s teaching and training business in New Oriental was frustrated. Yu Minhong was not discouraged, but took the lead in leading teachers to transform into live sales of agricultural products.

Yu Minhong’s resilience in the face of difficulties comes from his usual exercise.

Wang Xiaobo said: "Life is a slow process of being hammered."

Exercise gives us the resilience and confidence to wait for a bright future when facing the life of mountains and rivers.

Ming Chen, the champion mentioned by Qipa, once said: "Nothing in the world is meaningful, but meaning is given by people. And persistence itself is an extremely shining meaning. "

Insisting on exercise is to protect our health and expand more possibilities for our life.

At the beginning of the new year in 2022, I hope that when we make New Year’s resolutions, sports can squeeze into our crowded wish list, and I hope that everyone of us can enjoy sports.

Love sports, this is the way we adults should pursue health.

Running, skipping rope, climbing stairs … hurt your knee? Don’t worry about it. Look at the exercise guide for the best of both worlds here.

When it comes to exercise, many people are worried about hurting their knees.

So what kind of exercise hurts the knee the most?

The answer is

Sitting for a long time hurts your knees the most!

Long-term sedentary articular cartilage will gradually lose nutrition and "starve to death"

So exercise properly.

To prolong the life of the knee.

But the premise is to master scientific methods.

Avoid unnecessary damage.

Deputy chief physician of orthopedics

Climb mountains and stairs

Risk of knee injury: ★★★★★★★

When going up the mountain (stairs), your knees will bear about three times your own weight.

When going down the mountain (stairs), the knee will not only bear the impact of the ground, but also increase the wear of the knee.

Therefore, it is not recommended to climb mountains and stairs as daily exercise.

Click on the picture below to see the correct posture of going up and down the stairs.

Key points of climbing without hurting knees:

The center of gravity is slightly forward when going up the mountain and slightly backward when going down the mountain.

Hold the railing to help or use the trekking pole.

Knee injury, good leg first when going upstairs, bad leg first when going downstairs.

Tip: Old people, overweight people and people with knee injuries are best to crawl less. Don’t insist on climbing if your knees are uncomfortable.

rope skipping

Risk of knee injury: ★★★☆☆☆

The risk of skipping rope to knee joint is mainly related to the venue.

Generally, the concrete floor downstairs in a residential area can’t provide an effective buffer for the impact force when skipping rope falls to the ground, and it is easy to hurt the knee for a long time.

Key points of skipping rope without hurting knees:

Choose plastic floor or cement floor to lay plastic mats.

When jumping, keep your feet close together to avoid bending your knees greatly.

The take-off height is 2 cm ~ 4 cm, so as to ensure that the skipping rope just passes through the soles of the feet.

Shake the rope with wrist strength and keep the big arm close to the torso.

jogging

Risk of knee injury: ★★☆☆☆

Jogging rarely causes knee injuries as long as it is not excessive.

A few people with obvious O-leg, X-leg deformity or knee joint disease and overweight should exercise reasonably according to the doctor’s advice.

Key points of running without hurting knees:

Warm up for 5-10 minutes before jogging, and run for 30-60 minutes every day, without paying too much attention to the distance.

Lean forward slightly, swing your arms naturally, and touch the ground with your forefoot.

Keep the speed "breathing, heartbeat is slightly faster but you can talk normally"

Plastic ground and asphalt road are selected for the site, and cement ground is not recommended.

Tip: Treadmill needs to be used with caution. If the setting is unreasonable and the speed is too fast, it is difficult for the average person to keep up with muscle strength and coordination after fatigue, but it is easy to get injured. In addition, the weight is too large, and the injured knee joint should be guided by a doctor.

At the same time, don’t be a "weekend hero" and suddenly go to exercise. Exercise should be gradual, gradually increase the amount, and the weekly increase should not exceed 10%. Don’t be a "weekend hero" and suddenly exercise.

a kind of traditional Chinese shadowboxing (tai chi chuan)

Risk of knee injury: ★★☆☆☆

Some people think that Tai Ji Chuan’s squats like "Ma Bu" will put too much pressure on his knees.

As a matter of fact, many scientific studies actually show that playing Tai Ji Chuan twice a week can not only protect the knee but also relieve psychological stress.

Key points of Tai Chi without hurting knees:

You need to warm up before playing Tai Ji Chuan.

Don’t squat too much in pursuit of beautiful movements.

You need to stand on one foot or rotate your body slowly.

Once knee discomfort occurs, don’t endure it and stop immediately.

Ride a bike

Risk of knee injury: ★★☆☆☆

When riding, people’s weight mainly presses on the seat cushion, and the force on the knees is relatively small, which also helps to strengthen the muscles around the joints.

However, if you ride too hard or take some wrong riding posture habits, it will also have certain health risks to your knees.

Key points of cycling without hurting knees:

Adjust the height of the seat to: when the foot steps on the lowest position, the knee joint slightly bends about 170.

Hold your head high while riding, keeping your knees and toes facing forward.

Keep riding at a constant speed, and don’t suddenly increase the speed by force.

Exert your thigh, and step on the pedal with the first third of the sole of your foot.

Tip: If there is obvious discomfort in front of the knee joint when riding a bicycle, it is necessary to minimize such activities.

Click on the picture below to see the details of riding a bike correctly.

swim

Risk of knee injury: ★☆☆☆☆☆

When swimming, the body is basically parallel to the water surface, and the knee joint is basically free of load, so it is best for the knee joint.

However, patients with knee injuries should avoid breaststroke as much as possible. Water resistance will impact the knee joint when breaststroke kicks, and long-term high-intensity breaststroke may aggravate the symptoms.

Tip: Freestyle and backstroke are more recommended to protect the knee joint.

Can knee pads help maintain your knees?

Many functional knee pads only sell a conceptual thing, and one thing that all functional knee pads do is actually heating. Keeping warm is a very important part of knee joint maintenance, because the joint itself is afraid of wet and cold.

Therefore, normal knee pads have two main functions.

1. Keep the knee warm

2. Increase the stability of joints.

If the functional kneepad is non-invasive to the knee joint, it is actually no problem to use. However, some people may be allergic to drugs for knee pads, so they need to be careful.

Knee pads used in osteoarthritis, the most important function is to keep warm;

The main function of knee pads used in traumatic arthritis is to provide extra stability for joints;

Primary synovitis and gouty arthritis may not be particularly important for the use of knee pads.

point out

1. Don’t rely too much on knee pads.

Long-term dependence will lead to muscle atrophy inside the joint, which is actually more unfavorable for the protection of the whole joint.

Especially for relatively young people, we must not rely too much on knee pads, but should make muscle strength stronger.

2, the temperature must not be too high, not too long.

3. Observe whether there is drug allergy in time.

4. Don’t wear too tight knee pads.

Too tight kneepads can easily lead to blood stasis, resulting in poor blood return, which may lead to thrombotic diseases of lower limbs, which may even be fatal.

Risk of knee injury due to jogging: ★★☆☆☆

What is culture? An over-interpreted problem, in fact, it is very simple.

"This man is really uneducated!" "This city has a strong cultural atmosphere."We often talk about culture, but have you seriously thought about it? What is culture?

According to statistics, there are more than 360 definitions of culture given by experts and scholars at home and abroad, and more than 200 are said to be more influential.

British Taylor, the father of anthropology, he in the study of human culturePrimitive culture, the pioneering workIn the book, culture is defined as:"Culture is a complex whole, including knowledge, belief, art, morality, laws, customs and all the abilities and habits acquired by human beings in society."

Yu Qiuyu’s definition of culture is said to be the shortest in the world: "Culture is a spiritual value and lifestyle that becomes a habit, and its final result is collective personality."Not counting punctuation, it is exactly 30 words.

An online essay about what culture is said: A real literate person does not depend on how many books he has read or what school he has attended, but should have four qualities:Cultivation rooted in the heart; Consciousness without reminding; Freedom based on constraints; Kindness for others.I personally agree with this view. Let’s share a few short stories that happened around me.

That winter, after the newly bought house was renovated, I bought Hisense LCD TV. On the first day, the delivery man sent the TV set home and told us that there would be professionals to install and test it tomorrow.

The next morning, when I got up and opened the curtains, I saw that there were snowflakes in the sky and a thin layer of snow had been covered on the ground. I thought at that time: I’m afraid the person who installed the TV can’t come today. Anyway, cable TV hasn’t been opened yet, so you can install it any day. Don’t worry.

About nine o’clock, the intercom doorbell rang in a hurry. I picked up the receiver, and there was a young man on the screen, saying that he had come to install the TV. I was surprised and opened the unit door for him.

When I heard a knock at the door, I opened the door. It was a young man who looked about thirty years old. But he was not in a hurry to enter the door, but stood at the door rummaging through the toolkit he was carrying. It was the weather in March 9, and I let him in, but he refused. He found two shoe covers from his bag and put them on his feet quickly before entering the house.

I smiled and said to him, "It doesn’t matter, don’t be so particular!" He replied: "This is my job responsibility, and it must be like this!"

Young people are quick with their hands and feet, and soon they installed the TV set and taught us how to use it. In the meantime, I handed him a cigarette and he said no; Made tea for him to drink, but he said he was not thirsty.

Standing at the window and looking at his far-away back and a line of footprints left in the snow, my heart was moved by his little move of putting on shoe covers.

At the beginning of that year, we traveled to Taiwan Province. The tourist bus is running on the expressway, and my friend’s three-year-old daughter suddenly wants to urinate. A friend asked the female tour guide if she could ask the driver to stop the car so that her little daughter could go under the car for convenience.

These days, the driver and the tour guide are accompanied all the way, and we are already familiar with each other. There is only a friend’s little daughter and a child in the car. Without waiting for the tour guide to ask questions, the words of the middle-aged male driver came up: "It’s not convenient to park on the road, just let her do it in the car. The urine of the boy is very expensive!" My friend was very grateful to hear the driver’s words.

After parking at a scenic spot, a friend wanted to find tools to clean the car. The driver said to his friend, "You go and play well, just let me do this!" My friend was very touched. Although it is a small thing, it makes people feel incomparable comfort and warmth.

Walking in the square early in the morning, a little girl of four or five years old caught my attention. She stood not far from the dustbin, two small hands were peeling something, and she didn’t see it until she got closer. She is holding two packaged milk tablets in her hand, and she is peeling the packaging tin foil with her small hands. Inadvertently, two tiny pieces of tinfoil fell to the ground. The little girl bent down to pick up the tin foil on the ground and threw it into the dustbin. She stood beside the dustbin and threw the stripped tin foil into the dustbin. When she saw me looking at her, she raised a piece of milk in her hand and gave me a sweet smile.

At noon, we ate at a fast food restaurant in a seaside scenic spot. The sun is like fire outside, and the heat wave attacks people; The air conditioner in the store is open and the temperature is suitable. A little boy of four or five years old has been standing at the side of our dining table. At first, it didn’t attract our attention. There are many people dining in fast food restaurants, and diners waiting for seats are everywhere. In the meantime, I looked at the boy carefully: white skin, clean and decent clothes, small age, neat and orderly hair, not like a wandering child. When we are almost finished, he looks at us from time to time. I’ve seen boys stand for so long and look at us from time to time. I leaned close to him and asked, "What can I do for you? Can I help you? " The little boy told me in a childish voice that he was waiting for our seats. Grandparents are still waiting over there. Following his eyes, we saw an elderly couple with outstanding temperament not far away, standing quietly waiting for their seats. My wife and I quickly finished eating the food on the table and immediately asked the little boy to invite his grandparents. "Thank you, grandparents!" The little boy did not forget to thank him. The elderly couple smiled and nodded to us, and politely said "thank you!" As we were leaving, the little boy waved and said, "Goodbye, grandparents!"

I deeply felt: it is rare for a child at a young age to know the rules and be so polite.

One day, walking in the yard of the community, an old man in front of me was walking with his puppy. Soon, the old man and the dog stopped. I didn’t know what they were going to do, so I slowed down. When I came near, I found that the puppy had just finished excreting. I saw the old man take out a stack of toilet paper from his coat pocket, which was dark in color and thick in texture. The old man pulled out a few pieces, squatted down to pick up the excrement wrapped in the puppy and threw it into the trash can. To be honest, this is the first time I have seen what a dog owner has done. The old man’s behavior is not like a temporary act, but more like a long-term habit. The old man’s actions are moving! I am thinking: If all dog owners can do this, what kind of situation would it be?

Many times, culture is a hidden existence. Maybe we often can’t see the concrete image of culture, but it is obviously very important to us.It will make your thoughts richer, your work more independent, your life more interesting, and your behavior more civilized and elegant, which is not only beneficial to yourself, but also a little contribution to social progress.

Bai Yansong once said: "Whether a person has a culture or not depends not on his studies.How high is the calendar. People with academic qualifications do not necessarily have culture; People without education are not necessarily uneducated. Reading a lot of books, having a high diploma, and having education are sometimes completely different. "

Chinese and foreign scholars say cultural relics: capturing the "bright spot" of China culture in artifacts.

China news agency, Shanghai, November 25 th: Chinese and foreign scholars say cultural relics: capturing the "bright spot" of China culture in artifacts

China News Service reporter Wang Wei Kang Yuzhan

The World Congress on China Studies and the Shanghai Forum were held at the Shanghai International Conference Center from 23rd to 24th. At a sub-forum held on 24th, Wang Chunfa, director of the National Museum of China, presented a precious cultural relic in the museum-bronze rhinoceros statue with gold, silver and moire patterns in the Western Han Dynasty, from which he realized the unique charm of Chinese civilization.

This statue is in the shape of a rhinoceros, with its head held high and its eyes inlaid with black beads, which is the image of Sumen rhinoceros who lived in China in ancient times; The whole object is decorated with staggered gold and silver moire as thin as hairspring, which is exquisite and gorgeous, and it can be called a fine bronze ware in the Han Dynasty. The bronze statue made of animals shows the concept of harmony between man and nature and the nature of Taoism in ancient China.

"This precious cultural relic not only vividly narrates the past, but also profoundly affects the present and the future, enlightening us to respect history, respect our predecessors, respect nature and protect the environment." Wang Chunfa said that human knowledge is accumulated through exploration from generation to generation, and it should be passed down from generation to generation. Chinese and foreign scholars are welcome to the National Museum of China to feel the moving place of the bronze rhinoceros statue with wrong gold, silver and moire.

What are the China cultural relics that foreign scholars are interested in? In the face of a reporter’s question from China News Service, Han Yili, a former associate professor in the Literature Department of Moscow Humanities University, made a list on the spot-Oracle Bone Inscriptions, bronzes, silk books of Mawangdui … Some of them were related to the topic of Zhouyi he studied, and the other part was out of his personal interest.

In Han Yili’s view, the importance of ancient cultural relics and historical documents lies in helping people truly understand the ancient world outlook and living conditions. Compared with some subjectively recorded words, real artifacts can reflect a period of history more intuitively. "Many cities in China have their own museums, so that everyone can learn history and experience culture from ancient artifacts. How to better protect cultural relics and inherit culture is where we should learn from China. "

Yi Xin, an international student from Shanghai University in Mexico, immediately thought of blue and white porcelain. "I found that China’s blue and white porcelain is very similar to some artifacts I saw in Mexico. Later, I read the literature to know that these artifacts really came from China. Exploring how these artifacts arrived in Mexico from China and looking for connections between different cultures made me feel very interesting. "

Yi Xin told reporters that China has a long history and China culture has many "bright spots", which let her know the real China from different angles. "We will not stop exploring China, because there are many things worth studying here." (End)
