God of black technology

"What difficulties do you think are still possible?" Ma Botao looked at Wang Yun with a smile, raised his eyebrows, "Think about it, what are the difficulties for you at present?"

Wang Yun tightly clenched the data in his hand, frowned and thought for a while, and then said, "A one-equation model of the SA model?" When he said this, Wang Yun became puzzled again, "But I don't think it's quite right. Son, you said that according to the conventional theory, one side forms a model, that is, the calculation of differential equations, such a simple calculation, even if you are a freshman in your college of physics, it is impossible to be wrong."

"Hey, where is it? How can a freshman in the School of Physics compare with a freshman in the School of Mathematics? I think that when I was in the School of Physics, I looked at differential equations with a confused face. You guys from the School of Mathematics in Beijing University Don't mention how slippery the freshman's new differential equation is." Ma Botao changed into a white coat while talking.Looking at Wang Yun with a half-smile, he said, "Are you sure you don't want to change your clothes?"

"Hey." Wang Yun put down the information in his hand, took a white coat and put it on, and at the same time muttered, "No, as far as DNS is concerned, the SA model is very simple. The turbulence laboratory of Beijing University is also a national A key laboratory? And there are so many SCI journal papers every year, and there are many achievements. How can you not even handle the SA model?"

"Are you sure it's just an SA model?" Ma Botao raised the corner of his mouth, "Take a good look at the information, boy, it's as simple as you imagined. Beijing University should take the lead in cooperating with China University of Science and Technology, and our National University of Science and Technology should also participate?"

"There are only three turbulence models, the average NS equation solution, LES is the large eddy simulation you used in NPU, and our current DNS direct numerical simulation." After changing his clothes, Wang Yun lived on a chair in the laboratory and said thoughtfully, "You just added CFD to it, didn't you?"

"What a smart young man." Ma Botao walked up to Wang Yun, stroked his hairy head and said, "So, young man, do your calculations carefully."

"..." Is your turbulence laboratory sick?Add a CFD to me in the flow field, Wang Yun rubbed his eyebrows, then he had to overthrow and recalculate after the completion of his calculation just now.There was a moment of silence, no wonder he felt something was wrong just now, the more he calculated, the more strange it became.

"By the way." Wang Yun looked at Ma Botao, "Brother Ma, since there is CFD, why can't we use a computer to calculate it, it's much faster than humans."

"Because the one-equation model is mixed, it is too difficult to set up, and there are errors in the calculation. Before, it was calculated by computer. Now there is no way. I can only hope that your data research center can solve this problem as soon as possible." Speaking of this, Ma Botao also picked up After reading a document, Wang Yun glanced at it, and Ma Botao seemed to be referring to CFD-related materials.It seems that Brother Ma is still good at what he has learned.

Wang Yun didn't speak, but calculated silently.Ma Botao continued to sketch on the materials with a pen, and the whole night passed.Brother Ma yawned, looked at Wang Yun and asked softly, "Are you tired?"

"Also... okay." Wang Yun shook his hand. It is not difficult to solve the one-equation model, as long as you know the flow control equation, it is very simple.However, the calculation of CFD is more complicated. Wang Yun only solved half of it all night.

Ma Botao looked at Wang Yun and said, "Okay, don't be so tired, go back and rest quickly? I heard that Professor Chen has already asked you for leave today, so you should go back and rest quickly, and see if you will come tomorrow." .”

Wang Yun let out a cry, and looked at Ma Botao, "Brother Ma, isn't this information you are in a hurry to ask for?"

"Of course I'm in a hurry." Ma Botao smiled at Wang Yun, patted Wang Yun's shoulder and said, "Even if we are in a hurry to ask for information, we can't abuse you, hurry up and go back to rest. Otherwise, Professor Chen from the Data Research Center will have another opinion later."

Wang Yun could see the bitter smile on Ma Botao's face. After thinking about it, maybe what Professor Chen and Brother Ma said?No, seeing how angry Professor Chen was that day, maybe the professor even gave Ma a good beating.

emmmmm... It seems that Brother Ma is not having a good time at Beijing University these days.

However, in order to live up to Brother Ma's intentions, after Wang Yun packed his things, he talked to Brother Ma and walked out of the laboratory.

When Wang Yun was leaving, Brother Ma also specially instructed that Wang Yun's ID card was the work number for entering the laboratory, and if he disappeared, he had to tell him as soon as possible.Although they are not a secret experiment now, the turbulence model laboratory of Beijing University is also a national key laboratory, and there are many things that cannot be leaked out.

Back in the dormitory, the three roommates had already gone to class.After Wang Yun washed up, he lay down on the bed and had a good sleep.When he woke up, he realized that his roommate had not only returned, but was still discussing something.

Xu Changying's home is not too far from Yucheng, and Lu Yongnian is from the north.So Xu Changying wanted to invite Wang Qiuyang to play with them, Wang Yun opened his eyes in a daze, sat down and looked at them and said, "The capital is going to be cold in October, don't you guys bring more clothes? There is still time to visit." Rubbing his eyes, Wang Yun got off the bed and sat on his chair.

Wang Qiuyang looked at Wang Yun in a daze, and said with a smile, "Are you awake?"

"Otherwise?" Wang Yun looked at Wang Qiuyang suspiciously, "Isn't it strange that I can still sleep if you make such noise?"

"It's not too noisy." Wang Qiuyang touched the bridge of his nose, "Have you finished your data yet?"

"Not yet." Wang Yun yawned and walked to the balcony outside the door, turned on the faucet and said, "They are really sick, do you know what they did?"

"whats the matter?"

"They added the CFD calculation mode to the one-equation model. What do you think they want to do?" Wang Yun's interrogative sentences are no different from soul torture.The three freshmen from Beijing University were stunned, not knowing what to say.

On the SA model alone, the one-equation model, or CFD, they can all speak clearly.After all, he is a student of Peking University, so he still has some knowledge.But the problem is it's all mixed together, and they're really kind of confused.

"It should be quite difficult...to untie it, right?" Lu Yongnian was silent for a long time before he said this.

"It's more than difficult to solve." Wang Yun sighed, "I solved half of it after one night of calculation."

"Boss's speed is only half of the solution?" The three of them were stunned for a while, and then they said, "It seems that we are really not suitable for scientific research now, and I feel that we will be driven crazy."

"Big brother's math is so good, it looks like he's going to be driven crazy, it's a sudden heartache!"

"Distressed +1."

"Distressed +2!"

After Wang Yun washed up, he smiled at them, "Don't feel bad, I'll go out to have a meal, and then continue to stay in the laboratory. After today, you can leave, right?"

"It's not after today, it's already a holiday now." Lu Yongnian corrected Wang Yun very seriously, this is a holiday.This was the last few days when he didn't have to face Wang Yun with a full heart. How could God Yun remember such a pleasant thing wrong.

Therefore, Lu Yongnian was extremely serious.Wang Yun smiled and said, "Okay, you are going back soon, and I should go to the laboratory to stay." When talking about this, Wang Yun clasped his fists and said, "Let's just say goodbye, after the National Day, Let me see your weeping faces."

"???" The three looked at Wang Yun, wondering why they were crying and what happened.It feels like the boss got some great news.

"You don't know yet, didn't the counselor tell you?" Wang Yun said cheerfully, "Then let me tell you, there will be an exam after the National Day, you can figure it out?"

"Mist Grass!" Lu Yongnian jumped eight feet high, looked at Wang Yun and asked, "Boss, is this news true or not?"

"As far as I know, the Institute of Physics, Mathematics, and Chemistry must have exams. As for the other schools, I don't know much about it." After Wang Yun finished speaking, he walked out of the dormitory refreshed.Hehe, it's not that easy to go home.Do you really think that Peking University is the same as ordinary universities?

What is Beijing University, do I need to repeat it again?

There are so many masters, how can we find a peerless master among so many masters without taking a test.Boys, the pattern Tucson is still broken.

While eating, Wang Yun turned on his mobile phone and found that Ma Botao had sent him several prestige messages.However, Wang Yun is now obsessed with studying, and generally does not log in to any mobile phone software except for phone calls and text messages.So Wang Yun really didn't see it, and sent a message to Ma Botao while eating——

【Is Brother Ma awake?I'll be in the lab soon! 】

After a while, a message from Ma Botao also came over——

[Sleep well so soon?That's fine, come here first, let's talk later! 】

Putting the phone in his pocket, Wang Yun hurriedly finished the fried rice.He hurriedly walked to the gate of the turbulence laboratory and swiped his card to enter.The entire turbulence laboratory seemed a little quiet.Wang Yun turned around and walked into the laboratory, where Ma Botao was already studying the data.Wang Yun sat beside him and said, "Brother Ma, you got up so early today?"

"Ah." Ma Botao rubbed his brows, "I slept for four hours and was woken up again. The need is urgent, and I can't help it." When he said this, he was silent for a while, " By the way, Wang Yun, why don't you rest for a while?"

"It's okay." Wang Yun smiled, "There is nothing to rest."

"Let's finish my own business first." When he said this, Wang Yun had already started to do his own business.

Ma Botao nodded, and did not continue talking, but was doing his own thing quietly.

The original experiment was like this, and it didn't have to be very busy.Especially when two people read the materials one by one and calculate the data by the other.There was no unnecessary communication. After a while, Wang Yun filled up the draft paper.After a moment of silence, he said, "Brother Ma, look at this data."

Ma Botao stretched his head to look at the data that he told Wang Yun, he was stunned for a moment, squinted his eyes and said, "Is the stickiness of this data not correct?"

"Using the average NS equation to calculate once?" Wang Yun was asking for opinions, and Ma Botao nodded slightly.Regarding calculation, Wang Yun is indeed better than him.

So, after Wang Yun calculated it once, he still came up with this data.He scratched his head and thought, could it be his own illusion that he thought this value was ridiculous just now?Even if it is an illusion, his intuition has always been quite accurate.Squinting his eyes, Wang Yun stared at the value and looked again and again. After a long time, he said, "I still feel something is wrong."

"En?" Ma Botao leaned over his head, stared blankly at the value written by Wang Yun on the draft paper, and said, "There should be nothing wrong with it."

"No, no..." He shook his head and said, "Brother Ma, do you believe me?"

"Still..." Ma Botao nodded, hesitated and said, "I trust you."

"Then I don't count it as data for the time being." Wang Yun put down the pen in his hand and said, "Brother Ma, can you take me to the laboratory to have a look?"

Ma Botao hesitated for a moment, "Why do you suddenly think of going to the laboratory to have a look?"

"Because I have some doubts in my heart, I always feel that I can only be sure if I go to the laboratory." Wang Yun smiled and looked at Ma Botao, smiling harmlessly.

Ma Botao thought in his heart, this is not a secret project, Wang Yun was originally one of the core team members of the laboratory, and there is nothing wrong with entering the laboratory.

So he nodded and said, "Okay, but I can't go to the laboratory right now, wait a few days." Speaking of this, Ma Botao smiled, "Some people in the turbulence laboratory are on vacation, and they said they have to wait until the National Day Come back later."

"???" Wang Yun looked at Ma Botao suspiciously, "Brother Ma, what are we doing now? The data must not be calculated. The experimenters in the turbulence laboratory are already on vacation. Does it mean that we have nothing to do? ?”

"That's not what you said." Ma Botao rubbed his eyebrows, "I still have an itinerary tomorrow, which is from CCTV. What about you? Is there anything you can do? I heard that Director Yang has also arranged an itinerary for you. Alas, our scientific research dogs can only be squeezed."

"No." Wang Yun didn't figure it out, "We're not celebrities, so why do we have to stand in front of the TV? Isn't that funny? Why is it so difficult to do simple scientific research?"

"Isn't everyone emphasizing science and technology to rejuvenate the country now?" Ma Botao said thoughtfully, "It's a good thing for our scientific research dogs to move from behind the scenes to the front of the stage. After all, it can attract more people to enter the pit of scientific research. You too I know that no matter what country you are in, doing scientific research requires talented people who will continue to do so. Not just one person will be able to support it all the time. Maybe for decades, there will be a certain big cow who can support the country's science and technology all the time. , but what about after that big cow passed away? What if there is no successor?"

"So, the fundamental purpose of our scientific research dogs from behind the scenes to the front of the stage is to let more people understand science, and also join the scientific research industry." After Ma Botao finished speaking, he looked at Wang Yun and found that he was still a little wrinkled He frowned, so he said, "It doesn't matter if you don't figure it out now, anyway, you will figure it out in the future. And, after you become a professor in the future, you can decide this kind of thing yourself, so you work hard and strive for yourself Go to professor."

"Well..." Wang Yun was silent for a moment, "This is a good idea."

"Even if you become a professor, you still have to be squeezed by academicians."

"But there is much more room for autonomy. In short, the National Day is a rare opportunity." Ma Botao shook his head and said, "Take it as a change of mind. In fact, there are not many such things, and you will know in the future. One year, Just once or twice."

"Brother Ma has been on TV before?"

"No." Ma Botao shrugged his shoulders, "This is also my first time. I was so flustered that I wanted to learn from you."

"What's the matter?" Wang Yun said with a smile, "Just relax." After the two talked for a long time, Wang Yun walked out of the turbulent flow laboratory, just in time to be caught by Director Yang.

Wang Yun was shocked, "Director Yang, why did the experimenters have a holiday when we agreed to carry out the experiment on National Day?"

"Hey, what can I do when they are on vacation?" Director Yang said, "I am the director of the Mathematical Research Center, not the director of the turbulence experimental model."

"..." So you admit to lying to me?

"But Xiao Wang." Looking at Director Yang's appearance, Wang Yun felt that nothing good happened.

Sure enough, Director Yang said in the next sentence, "No experiment on National Day, what do you think?"

"Reading in the library?"

"No, you don't want to read."

"Then—go home and rest?"

"Well, yes, that's a good suggestion."

"Then I'd better go to the library to read." With that said, Wang Yun was about to start walking.Director Yang hurriedly grabbed Wang Yun and said, "You child, what's the matter? I haven't finished my sentence yet."

"No." Wang Yun looked at Director Yang, "If you always have something to say, just say it. I'm scared if you hold it in like this."

"Actually, it's not a big deal. I just asked you to send a copy of the materials to Professor Wan." Director Yang patted Wang Yun on the shoulder, "I trust you and let you send this materials."

When talking about this, Director Yang seemed to think of something and said, "By the way, you should prepare yourself. After you come back from the National Day, Beijing University will have some academic seminars on Zhou's conjecture. At that time, you will be the protagonist." .”

Why do I feel like I've been tricked?Is it my own illusion?Wang Yun silently looked at Director Yang without speaking.

After Director Yang finished speaking, he turned around and left.

Covering his face, Wang Yun started to have a headache.He just said that he would not leave the capital, but he didn't expect that he would have to go back to Yucheng when he turned around.I don't know if I can book a ticket, Wang Yu chased Director Yang and said, "Director, Director, you have to give me the information. Besides, you said that I am going to Yucheng now, so I can still book a ticket? "

"It's been booked for you a long time ago." Director Yang said with a smile, "Don't worry, it's a good thing that I didn't cheat you." After finishing speaking, he winked at Wang Yun.It made Wang Yun look dumbfounded...

The more I think about it, the more I feel that there must be something weird about it.

Have to prevent!
