January 10, 2016.
The world is very big, and big things are happening every moment.
At that moment, several major events were happening, related to the young man Wang Donglai.
The first thing is that with the strong support of BYD and Tangdu City, the semi-solid battery production line was successfully launched.
Brother Boatman knows very well what semi-solid-state batteries represent. Even if there is no way to achieve large-scale mass production now, its excellent performance can already beat other new energy vehicle brands on the market. .
Whoever can take the lead in using semi-solid-state batteries will occupy a large amount of the market.
That’s why Boatman paid a huge price to win the cooperation of semi-solid-state batteries.
For this time's semi-solid-state battery, it has been booked by major mobile phone manufacturers before it has even rolled off the production line. There are so many orders that if the current production line speed is to be followed, full production will not be possible until next year. satisfy.
There is only one way, and that is to increase production lines and expand production scale.
Of course, some people believe it, and naturally some people don’t believe it, thinking that this so-called semi-solid-state battery is completely a lie from China.
Just like the Dragon Chip incident back then, it was a complete scam.
The second thing happened in Magic City.
Center International.
Chip production super factory.
As one of the top semiconductor companies in the country, although Central International is nothing in the world, its status is different in the country.
At this moment, in the super factory, a large number of company executives and some relevant leaders of Magic City gathered.
The purpose of so many people gathering here is to witness the application of domestic ‘advanced packaging’.
Although it was Wang Donglai who had come up with advanced packaging technology before and had already proven it.
However, it has not been applied on a large scale.
After paying a certain price, Center International obtained the copyright of advanced packaging from Wang Donglai.
After all, it is a large domestic semiconductor company, and it still has talents.
After several months of study and exploration, the first high-performance chip belonging to China and Central International will be born soon.
Although it is not as good as the current mainstream chips, it is not much worse.
If it is proven that it can be mass-produced, then the significance of ‘advanced packaging’ will be huge.
The importance of the semiconductor field in today's modern and intelligent era can be understood by anyone with a normal IQ.
Let's illustrate with a simpler example.
That is, as long as the 65-nanometer lithography machine is realized in China, it means military independence. There is no need to worry about problems with military equipment at critical moments, and the practicality of military weapons can be guaranteed at any time.
Many weapons in the military field are no longer the original small biubiu and big pengpeng. There are all kinds of intelligent weapons, and they work together to form a complete military system, each of which is indispensable.
The more advanced the function, the higher the intelligence, and the required chips require higher performance.
If there are only one or two machines, even if the yield rate is low, they can be smashed out.
But naturally there can't be only one or two weapons, so the method of spending money on them won't work.
This is just the change brought about by the realization of the 65nm lithography machine.
According to Moore's Law, ICs of the same specifications can be produced on wafers of the same area. With the advancement of process technology, IC output can double every one and a half years. When converted into cost, that is The cost can be reduced by 50% every one and a half years, and the average annual cost can be reduced by more than 30%. ,
As an extension of Moore's Law, IC technology advances one generation every one and a half years.
65nm can only be called excellent for a period of time, but with the advancement of process technology, better chips will naturally appear.
Once our country realizes the 28nm lithography machine, it will mean industrial independence.
There is a very counter-intuitive piece of trivia. Industrial products such as air conditioners, refrigerators, washing machines, and automobiles have been in the world for more than a hundred years. Logically speaking, they are mature products that cannot be matured any more. , but many countries are still unable to complete independent manufacturing and production.
Industrial independence means that once it is decoupled from the West and restricted by technical sanctions and equipment, the country can still produce and sell on its own.
Going further, once the 14-nanometer photolithography machine is reproduced, it means that the domestic electronics industry has entered the formal stage.
Mobile phones, computers, monitors, CPUs, GPUs and other electronic industries can immediately get rid of foreign sanctions and restrictions.
Below 14 nanometers is 7 nanometers. If once realized, it will mark China as the world's science and technology center.
And this is the importance of the semiconductor industry.
The lithography machine is the brightest pearl in the industrial crown, and it is naturally impossible to surpass it in a short time. There, 'advanced packaging' has become the only hope for overtaking in a corner.
Soon, the first chip designed using the ‘Advanced Packaging Design Solution’ was produced from the assembly line.
As soon as possible, it was taken for testing by relevant staff.
Everything has been prepared, so the detection speed is very fast.
The result was no surprise at all. The chip was successful and the performance increased by 53%.
Of course Wang Donglai couldn't hear the cheers of the Central International Chip Production Super Factory.
The third thing happened abroad.
There is news in the international market that Siemens will spend US$4.5 billion to acquire Mentor Graphics.
Once the acquisition is successful, it means that the international EDA industry will undergo huge changes.
However, this will not affect Wang Donglai for the time being.
At this moment, Wang Donglai, after determining the development route of Galaxy Technology, came to the Astronaut Research and Training Center under the Aerospace Group.
“The selection of astronauts is a long and rigorous process. First, they need to pass basic condition selection, medical selection and psychological selection, which includes clinical medical examination, physiological function examination and psychological evaluation.”
“During the selection process, candidates’ personal information and files will be reviewed for basic qualifications and preliminary clinical experience, and those with obvious diseases and functional impairments will be screened out.”
"The re-selection also requires a comprehensive inspection and evaluation of the candidates who qualified in the preliminary selection. The final selection stage is the evaluation and admission stage, and a further in-depth inspection of the candidates is conducted."
"Our country’s astronauts are selected. The conditions are so harsh, although it can’t be said to be one in a million, but one in a hundred thousand, there is absolutely no problem!”
The aerospace field is relatively closed, and it rarely cooperates with some outside universities.
However, Wang Donglai is different.
Not to mention Wang Donglai's status as an academician at this time, his achievements in the field of mathematics alone are enough for experts in the aerospace field to have goodwill towards Wang Donglai.
Not to mention, Wang Donglai has something to do with the aerospace field. Therefore, it is not difficult to enter the scientific research and training center.
At this time, it was Director Song Lin of the training center who was explaining to Wang Donglai.
When mentioning the harsh selection conditions for astronauts, Director Song Lin showed a sense of pride on his face.
The selection of astronauts in our country is indeed extremely harsh.
Applicants need to be between 25 and 35 years old, 1.60 to 1.72 meters tall, 55 to 70 kilograms in weight, and have more than 600 hours of flight time. These are just the preliminary conditions.
The screening cycle lasts for two years, with numerous procedures and complex projects. The severity is unheard of, and even family members also need to undergo physical health examinations.
There are some things that Song Lin did not say, but Wang Donglai has read relevant articles.
That year, there was the first manned space mission in China.
A total of more than 3,000 fighter pilots participated in the preliminary selection, and only 14 were left in the end, with an elimination rate of over 99%.
And of these 14 people, not all of them flew into space in the end.
This shows that astronauts are rare.
“Our country’s aerospace industry has such an attitude that it can develop so well and so fast.”
“I have always believed that the future universe will be ours. The Chinese took the lead in the development.”
Hearing what Wang Donglai said, Song Lin suddenly became curious.
In the past, when others heard about the selection conditions for astronauts, they would either look shocked or envious.
However, Wang Donglai did not do this. Instead, he said this sentence with a calm expression and full of confidence.
Curious in his heart, Song Lin asked aloud: "Academician Wang, I would like to hear your opinion, why do you say that?"
"It's very simple, from the name You can see the difference between us and the West.”
“We call them astronauts, but they call them astronauts. Although the meaning is similar, the spirit is completely different.”
"Although it is just a small title issue, it actually hides the broad and generous spirit of our country."
"These things may seem inconspicuous and have no effect at ordinary times, but when they truly reflect When it works, it already means we have succeeded.”
"Astronaut and space navigator, Director Song might as well taste it carefully. Which one is more dignified and more powerful."
Wang Donglai saw the trace of pride on Song Lin's face. After the proud expression, you know what this person's character is, and his words are just right.
After saying this, Song Linxi smiled brightly.
"Academician Wang is indeed an academician. I really never thought about this. I always thought it was a translation problem, but I didn't expect that there would be such an inside story."
"Astronaut, Astronaut, the more I listen to it, the more courageous I feel.”
A strong smile appeared on Song Lin’s face, recalling the title of astronaut.
At this time, the two of them also walked to the training ground.
Song Lin also came to his senses and introduced Wang Donglai with a smile.
"Academician Wang, I just talked about the selection conditions for our country's astronauts. Now let's talk about the training content of our country's astronauts. Academician Wang, don't worry, these things are not confidential and do not violate regulations!"
He made a small joke to liven up the atmosphere.
It can be seen with the naked eye that Song Lin's attitude towards Wang Donglai has changed from the unfamiliar and polite attitude at the beginning to a hint of kindness.
“Our international astronaut training content is comprehensive and systematic, aiming to comprehensively improve astronauts’ various abilities. The training subjects include basic theoretical training, physical training, psychological training, space environment adaptability training, life-saving and Survival training, aerospace professional technical training, such as extravehicular activity technical training and rendezvous and docking technology Training, flight procedure and mission simulation training, large-scale joint exercises and other 24 types of training.”
“In addition, astronauts also need to participate in man-ship joint tests, man-ship station-ground joint tests, and long-term manned tests. Comprehensive simulation verification experiments and other various engineering development and test activities, and deeply involved in the preparation of flight manuals and plans.”
“These things sound very complicated, but they are not all the training content for astronauts.”
“Because of the special environment of space, astronauts must receive special environment adaptability training to adapt to the conditions in space. Extreme conditions, this includes overweight endurance and adaptability training, vestibular work Ability training, landing impact experience training, neutral buoyancy tank training, etc. "
"The purpose of these trainings is to enable astronauts to withstand large overloads during the ascent and descent of the spacecraft and improve the vestibule. Functional stability, prevention of movement in space, and maturation in simulated weightlessness Practice and master the movement and posture control of the body.”
“Finally, there is special training for extravehicular activities, special training such as extravehicular program training simulators and extravehicular suit experimental cabins, and simulated real-world training equipment. There is also a more important training, which is lifesaving and survival training. ”
“After all, rocket launches and returns are extremely dangerous activities. No one knows whether there will be any sudden dangerous situations. In order to deal with these possible emergencies, this special training was developed. , giving astronauts the ability to survive in harsh environments.”
Song Lin introduced Wang Donglai while leading Wang Donglai towards the training center.
Soon, a lot of various machines appeared in front of Wang Donglai.
"Academician Wang, this is a manned centrifuge. It is the nightmare of most astronauts. It is also this equipment that has wiped out many reserve astronauts."
As he said that, Song Lin He took Wang Donglai into the control room.
Wang Donglai came to this kind of place for the first time. In his previous life, he had only seen it online.
I couldn't help but feel a little excited and became more active.
Song Lin noticed Wang Donglai's change and didn't find it strange.
At first, when he learned that he would receive Wang Donglai and do the explanation task, Song Lin was a little reluctant.
After all, in his opinion, this is a complete waste of his time to satisfy a young man's curiosity.
However, as he communicated with Wang Donglai, Song Lin developed a good impression of Wang Donglai.
If it were other visitors, Song Lin would not bring them into a place like this. He would only take a look outside and give a few introductions.
"Director Song, do we have a complete set of astronaut training equipment here?"
Looking carefully at the manned centrifuge operating table, Wang Dong turned his head back and forth and spoke to Song Lin asked.
“Well, it’s all here!”
“The manned centrifuge is the machine in front of you, a three-dimensional space ring, an electric swivel chair, an impact tower, a diving pool, a simulator, There are test chambers and so on. In addition to survival and life-saving training, other training can be done.”
Song Lin's tone was as if he was recounting his family's treasures, and he reported his family's fortune.
Hearing what Song Lin said, Wang Donglai nodded.
At this time, Song Lin suddenly seemed to remember something, and said with a smile on his face: "Academician Wang, it is a coincidence that today, a group of pilots will come to select astronauts this afternoon. "
"Academician Wang, why don't you stay until the afternoon and witness the astronaut selection scene?"
Wang Donglai thought for a while, then nodded and agreed. (End of chapter)
