CCTV News:Speaking of Hua Tuo, everyone must be familiar with it. It is said that this imperial doctor in the Three Kingdoms period has a wonderful hand to rejuvenate the disease. In the Capital Aerospace Machinery Company under the China Academy of Launch Vehicle Technology, there is also a "doctor Hua Tuo". However, this doctor is not a doctor, but an old technician who repairs machine tools. He is Yang Jingde.

Yang Jingde, born in 1937, is a national senior technician, graduated from Shanghai Aviation Industry School (formerly "East China 250 Technical School"), and is one of the earliest military industry technicians trained in New China. At the age of 18, he was assigned to Nanyuan Aviation Repair Factory, today’s Capital Aerospace Machinery Company, and began to deal with cold machine tools.

Now, Nanyuan Aviation Repair Factory has developed into a base for the batch production and development of missiles and rockets in China. From green to old, Yang Jingde never left. He used his life’s wisdom and years to interpret his persistence in the space dream.

Another kind of "magic doctor": "looking, hearing and asking" to repair machine tools

In the 1950s, China’s space industry was still in its infancy, and the conditions were very difficult. Nanyuan aviation repair shop has only a total of hundreds of equipment, all of which are hand-operated machine tools. Yang Jingde doesn’t even have a desk in her dormitory.

However, Yang Jingde was never afraid of hardships, and especially loved to study hard, seizing every opportunity and time to learn advanced technology. Because of his outstanding performance, he was also sent to learn the maintenance of precision machine tools from Soviet experts. For this reason, he made every effort to cherish this hard-won learning opportunity.

At that time, Yang Jingde, who was very young, was already quite famous in the factory. Years of study and research and tempering on the production line have enabled him to practice a stunt: "looking, smelling, asking and cutting" the equipment like an old Chinese doctor.

The oil on the equipment guide rail is more or less, clear or turbid. Yang Jingde can tell the cause of the fault with his eyes.

He can also "listen" to the fault. A few years ago, a British imported equipment was abnormal. Yang Jingde went to the front of the machine tool, leaned down, listened to the noise of the equipment, and then felt the temperature and rotation frequency of the equipment with his hands. The roar in the workshop was extremely noisy, but it did not affect his judgment at all, and he found the "lesion" in a few times.

What’s more, there is another trick, "sound detection from a distance", which makes everyone have to admire the superb skills of this old technician.

One year, Yang Jingde had just finished gallstone surgery, and one of the equipment in the unit was broken. In order not to affect the production, he walked out of the hospital and went back to the workshop for a day. Until he found the cause of the equipment failure and solved the problem, the young comrades of the rest of the equipment could do it by themselves, and he dragged his tired body home. Who knows that at 9 o’clock in the evening, my colleague called and said that the machine that had just been repaired had broken down again. In desperation, he can only instruct the on-site personnel by telephone remote control: "You put your mobile phone next to the machine and I will listen." He vaguely heard the irregular noise in the roar of the machine.

"You put ‘ Lead screw ’ Clean it and see if there is anything extra. " Yang Jingde said.

After the maintenance master took down the "lead screw", he found that there was indeed something superfluous in it. It was aluminium scrap who wore the ball of the "lead screw", which caused the equipment to malfunction. Clean it and reinstall it. Problem solved!

Lay the foundation for your dream with your aerospace peers.

"On October 1, 1997, I began to enter the stage of re-employment, and the specific work was as follows … …” It can be seen from a yellowed Production Task Record Book that this old technician can retire 19 years ago. At that time, Yang Jingde was famous for his stunts, and many units wanted to hire him. The boss of a company came three times and offered him 5000 yuan a month. One company even said, "The salary is up to you, and you are hired as a consultant, so you don’t have to work."

At that time, the salary of rehiring old experts in the factory was 500 yuan per month. Before retiring, the factory leader only said to Yang Jingde: "The factory can’t live without you." He nodded without hesitation.

"I was trained in the factory. Everything I have is given by the factory. I can’t be ungrateful." Yang Jingde said. Not for fame, not for profit, Yang Jingde is like a rock. This firmness is the infinite loyalty of this old technician to the aerospace industry.

After rehiring, the leader always told Yang Jingde that he didn’t have to come to work every day, so call him if he had any questions. But he is still not at ease, coming every day.

Selfless and earnest attitude, marvelous machine repair technology, Yang Jingde has saved a lot of money and made progress for the factory over the years.

In the summer of 2014, an imported machine tool broke down seriously, and there was no maintenance capacity in China, so it had to return to the country of origin, with a maintenance cost of more than 1.3 million yuan and a cycle of at least 3 months. This is a high-precision machine tool, and no one dares to touch it. Yang Jingde looked at it and said, "It can be repaired!"

As a result, 77-year-old Yang Jingde stooped and got in and out of the equipment every day, sweating and working for 20 days. Finally, the machine tool was repaired with only 150,000 yuan. Yang Jingde not only saved "foreign equipment", but also saved more than one million yuan in maintenance costs for the factory. This shocked the original manufacturers.

In 2015, Yang Jingde was 78 years old. Considering his age, the company leaders were really worried about his physical condition, so they ended their re-employment. However, he is still the same as before, and the unit is responsive and has no words.

The old man who repaired machines walked with the aerospace industry all the way, and every progress of this career condensed his life’s hard work and pursuit. He is a witness and a founder. (Text/Liu Chang)

　　(video production: the main station is dreaming of the media creative studio)

　　Commercial aircraft has always been called the jewel in the crown of modern industry. On May 5, 2017, with the success of the first flight of China C919 passenger plane, China people’s dream of a big plane took another step forward. In the following five years, the C919 large passenger plane has been conducting evidence-based test flight. On September 29th, 2022, it ushered in the most important moment — — Obtaining the type certificate issued by the Civil Aviation Administration of China also means that after 15 years’ efforts, China has completed the whole process of design, manufacture, test, flight test and airworthiness certification of a large jet airliner in strict accordance with the internationally accepted airworthiness standards for the first time. The C919 has the "safety qualification" to deliver to customers and put into market operation, and it also marks that China’s airworthiness certification ability has reached the advanced level in the world.

　　For this important historical moment, two C919 aircraft flew to Beijing from the development site, which was the first time that a large C919 passenger plane flew to Beijing Capital International Airport. As the first "passengers", CCTV reporters from the main station followed one of the planes and experienced this unusual journey exclusively. This is the first time that a large C919 passenger plane has witnessed the report by the media since its first flight. What exactly is the interior of C919 cabin like? What kind of experience will you have when you take the C919 domestic large plane for the first time? The CCTV reporter at the reception desk reveals the secret for you!

We all know that the puppy of a dog is called Puppy in English and the kitten of a cat is called Kitten.

But, you know what? Goat cubs are represented by kid in English. Yes, that’s the kid we often refer to as a child.

Therefore, what we are going to learn with you today is the vocabulary expression of various animal cubs in English.

Are you ready? Let’s start now.

Duck –duckling

Eagle –eaglet

Eel (eel) –elver

Elephant –calf

Elk (moose) –calf

Ferret (white glaze) –kit

Fish –fry

Fox –cub/kit

Frog –tadpole

Giraffe –calf

Goat –kid

Goose –gosling

Hare (hare) –leveret

Red hartebeest –calf

Hawk (falcon) –chick/eyas

Horse –foal/colt/filly

Kangaroo –joey

Leopard –cub

Lion –cub

Mink –kit

Owl –owlet

Peafowl –peachick

Note: peacock means male peacock, peahen means female peacock.

Pheasant –chick

Pig –piglet/ porkling/gilt

Pigeon –squab/squeaker

Pike (pike) –pickerel

Possum –joey

Rabbit –kitten

Rat –pup

Rhinoceros (rhinoceros) –calf

Roedeer (roedeer) –kid

Salmon –parr/smolt

Seal –calf/pup

Sheep –lamb

Skunk –kitten

Spider –spiderling

Swan –cygnet

Tiger –cub

Toad (clam –tadpole

Wallaby (wallaby) –joey

Walrus –cub

Weasel –kit

Whale (whale) –calf

Wolf –cub/pup/whelp

Zebra (zebra) –foal

It can be seen that foal, kid, kit, joey, cub, calf and other words are the most commonly used in English names of animal cubs. spider and duck’s cub names all add ling after the original words, while eagle, owl and pig all add let at the end of the original words (because eagle has the letter le at the end and owl has the letter L at the end, T and et are added directly respectively).

For the convenience of memory, you can summarize the words of cubs with the same words or similar endings. In this way, the vocabulary has doubled in an instant!

Continued content

In this column, I will continue to introduce you to the related content of running.

1.?posture?

Let’s start with the posture. As a "most natural" sport, running hardly involves the cooperation between people and equipment (except running shoes, which will be elaborated in detail), and the running mode can be said to be a skill package brought by human beings, which is embedded in genes as people evolve to walk upright.

Since I became a father, I have watched my daughter fall to the ground, from learning to look up, turn over, crawl, stand, walk to run, and often lament the magic of the creator; At the same time, it is very enlightening to observe the movements of children! For example, if children want to pick up toys on the ground, or move a small stool, they must squat down, take them, and then squat up, instead of bending down and reaching for things on the ground first like adults; Another example is that when a child runs, the heel does not touch the ground first, but the sole touches the ground first.

When children learn to walk, their language communication skills are usually not fully developed, so these basic action patterns are not taught by adults-parents only do some auxiliary work such as help at most.Obviously, these basic movement patterns are "preset programs" that already exist in every child’s brain at birth.After a period of "debugging" and "running-in", children can use these preset programs normally, and the action differences between children are very small.??

Now the field of kinematics has fully paid attention to the value of the research on children’s sports patterns, and formed a special branch of developmental sports, and through some exercises, adults can gradually return to their original source in sports patterns.

2.?core

In the introduction of the last issue, we introduced the importance of posture-because of sitting or standing for a long time in life, and often because of poor sitting or standing posture, some wrong body habits are formed, which leads to "imbalance" in the body, and this "imbalance" destroys the core stability of the human body, so it is easy to compensate in sports and becomes one of the reasons for sports injuries.

In Tiesanluan, most fans are energetic and curious sports enthusiasts, and they are also willing to try new things. I remember that for a while, "practicing the core" was a very fashionable thing in the iron three laps (maybe it still is).

Therefore, all kinds of flat support, sit-ups and abdominal muscle tears are practiced happily, and you must regularly take photos of eight abdominal muscles in front of the mirror to prove the effectiveness of "practicing the core".However, when I returned to these special sports, I found that the previous problems still existed, so I went back to the above process and entered an infinite loop.?

This is the trouble of many iron three people-they are all practicing the core, and few people can tell what the core is, and even fewer people know how to use it.?

Generally speaking, the muscles that control the spine and body posture can be called core muscles.We won’t delve into it here. The body is like a complex but not very reliable engine. Only when all parts are in normal positions can the ideal output power be achieved, and the core function is to ensure that these "parts" can be in normal positions without deviation.

3.?DNS

Go on, running,Running mainly relies on the lower limbs to drive the body forward, and the legs do repeated periodic movements like pistons, while the pelvis is the fulcrum of the movement of the legs. If the fulcrum is not stable, the parts will deviate and the engine will act abnormally.. How to control the stability of the core to ensure the efficient operation of the engine? Here is a concept: dynamic neuromuscular stability (hereinafter referred to as DNS). Excuse me? If you know every word, you don’t know what you’re talking about. In this case, the purpose of my subject (zhuang) and general education (bi) has been achieved, and brackets laugh!?

Get down to business,Simply put, DNS is a technical means to help restore or improve sports ability through the stability of core muscles. Different from the usual methods of simply strengthening the muscle strength of waist and abdomen, DNS mainly controls the coordination of waist and abdomen muscle groups and intra-abdominal pressure through the motor nervous system to achieve the goal of core stability.

The diaphragm and pelvic floor muscles of the human body are like the lid and bottom of a mineral water bottle, and the abdominal wall is the body of this mineral water bottle. When your posture is correct, the diaphragm is opposite to the pelvic floor muscle, and you use abdominal breathing to inhale one breath into the abdominal cavity, which causes the intra-abdominal pressure to rise, just like filling a mineral water bottle with water and tightening the bottle cap. At this time, the structure and state of the bottle are very stable and not easy to deform. As shown in the figure below.

If the posture is bad, such as the pelvis leans forward excessively (many people will deliberately do this to make their chests stand high and their hips become warped), the relative position of the diaphragm and pelvic floor muscles will be destroyed, just like if you squeeze the bottle body of a mineral water bottle into it, even if it is filled with water, the bottle still cannot maintain structural stability. As shown in the figure below.

Through DNS, joints can be located in the best position, so as to obtain the best advantages of sports mechanics, and it is also conducive to the correct excitation of sports muscles. existIn long-distance endurance exercise, the muscle strength or endurance of a single muscle is not the key point. The key to improve exercise efficiency is to coordinate the work between muscles and stimulate them at the right time, and a good posture is a prerequisite for achieving efficient exercise..?

I hope this article will play a role in attracting jade, so that everyone can look at the "core" from another angle. We will talk about running shoes in the next column, so stay tuned.
