From Almighty Scholar to Chief Scientist

He couldn't help saying, feeling even more pity in his heart, why isn't that Lin Xiao one of them?

"By the way, what material is their artificial nerve made of? Is there any information?"

The Secretary of State shook his head and said, "There is no relevant information for the time being. They seem to be covering this material very tightly. Basically, we can't detect what material they used at all."

The president frowned: "So is there a way to get it and analyze it?"

The Secretary of State spread his hands and said: "There is no way to do this for the time being. This thing has not flowed out. It is difficult for us to get this by other means. In addition, this thing needs to be transplanted into the human body in the future. We can't let a paralyzed person take it. After an artificial nerve is removed, shall we remove it from him?"

"Why can't it? It's enough to make it secret enough. We can even say that their artificial nerves are risky. For example, when you are crossing the road, the artificial nerves suddenly lose their effect, and then a car happens to rush over, and then Just... bang, you know."

"This..." The Secretary of State was stunned for a moment, and then a smile appeared on his face, "It seems that it is not impossible."

The president also smiled, "Just do it like this."

Suddenly, at this moment, someone knocked on the door and came in.

"Mr. President, there are some problems now. There are many rich people who want to go to Huaguo, and they seem to want to receive the treatment of that artificial nerve!"

"There are quite a few?" The president was stunned: "When did we have so many paralyzed people among our rich?"

The person who came in said helplessly: "The family members of some rich people may be in need, so they all plan to go, and these rich people are only a part of them, and there are more ordinary people."

The president frowned immediately, and then said immediately: "Go and announce something, tell them not to go as much as possible, and even if they go, don't take their mobile phones with them, otherwise, it may cause us to leak the secret!"

"Yes!"

……

"Tsk, isn't this what the Winter Olympics asked their athletes to do? How come it's going to be done to them now?"

In China, when Lin Xiao learned about this incident, he immediately felt amused.

It's this trick again, without repetition.

And it was Ma Gaoliang who brought him the news, and Ma Gaoliang said with a smile: "These foreigners are almost full and have nothing to do."

"really."

Lin Xiao smiled, and then took another mouthful of rice.

At this time, they were eating in the cafeteria of the Dingguang Research Institute, and Ma Gaoliang was here to report the good news to Lin Xiao.

The second phase of clinical trials will start tomorrow. There are a total of six paralyzed patients. As for the first phase, Shi Hao is naturally the one. After a month, we will see how the results of these seven artificial nerve transplants are. The third phase of clinical trials can be considered. After the third phase of clinical trials, the artificial nerve can be officially launched.

Now, countless paralyzed people are probably already waiting impatiently. Even the application website for clinical volunteers is almost overwhelmed. Put on this thing.

But obviously, there can only be a small number of people who accept clinical trials each time, and it is impossible to be a majority. Therefore, there are even some people who want to rely on their relationships to become volunteers.

That's the appeal of artificial nerves that makes those with backgrounds so scrambled.

And at this moment, two people suddenly walked up beside them, carrying the food they just ordered, and sat down beside them.

"Director Lin, Director Ma."

One of them greeted with a smile.

Lin Xiao took a look, nodded and said, "Professor Shu, Academician Ma."

Professor Shu, whose full name is Shu Qingzong, is a professor of electromagnetic field and microwave technology at the National University of Defense Technology. He is currently in charge of the research of superconducting microwave weapons in the superconducting laboratory of Dingguang Research Institute.

Academician Ma, whose full name is Ma Weimin, is an academician of the Academy of Engineering and a professor of the Naval University of Engineering. At the same time, he is also an important national scientist who is highly sought after by fans of the Hua Guojun and called "Forever God".

Because the electromagnetic ejection technology of the Huaguo aircraft carrier was developed by this academician, and in addition, the shaftless pump technology of nuclear submarines was also developed by this academician.

It can be said that it is not surprising that Academician Ma is sought after by the majority of military fans.

As for why Academician Ma appeared here, it is natural that he is researching a new technology in the superconducting laboratory, called magnetic fluid propulsion technology. This thing, like the shaftless pump propulsion technology, is also the power technology of nuclear submarines.

For nuclear submarines, the first problem to be solved is the noise problem, and the main noise source of nuclear submarines comes from the propeller, the power part of nuclear submarines.

The propeller used by nuclear submarines in the past is basically a fan blade rotating, which is ordinary and has no characteristics, so the noise caused is very loud, and the shaftless pump technology, because there is no middle shaft, so the friction reduction, which in turn leads to a huge reduction in noise.

However, the shaftless pump technology still requires the rotation of the fan blades, but there is no shaft, and the rotation process will still cause noise.

The magnetic fluid propulsion technology is powerful. The magnetic fluid propulsion technology is to build a strong magnetic field in a channel through the seawater, and this magnetic field can generate electromagnetic force on the conductive seawater, making it move in the channel, and then borrow With the force of sea water, the nuclear submarine can obtain very powerful power, and at the same time, the noise has almost completely disappeared.

However, if you want to build such a strong magnetic field, ordinary magnets will definitely not work, so you can only build an electromagnetic field, and the increase in the amount of electricity in ordinary conductors will generate huge heat, which is even more impossible, so there is only super magnetic field. Magnetic fluid propulsion can achieve the expected function.

But in the past, superconductors needed liquid helium to cool down to achieve superconductivity, and it was obviously impossible to carry a lot of liquid helium on nuclear submarines, so in the past, superconducting magnetic fluids could only become a wonderful fantasy for submariners .

However, now that the emergence of room temperature superconductors can easily solve this problem, there is no need to think about liquid helium and liquid nitrogen, just build it directly.

Therefore, Ma Weimin should be more relaxed at this time.

However, what puzzled everyone present was that at this moment, Academician Ma had a very troubled expression on his face. After sitting down, he began to pick up his meal, as if thinking about other things.

"Hey, old Ma...cough cough, it's not Director Ma, I said Academician Ma, what are you thinking?"

At this time, Shu Qingzong probably couldn't stand it anymore, so he pushed the horse for the people and shouted.

Ma Weimin finally came back to his senses, as if he had just noticed Lin Xiao and Ma Gaoliang, and then shouted: "Director Lin, Director Ma."

"Hehe, it seems that Academician Ma has encountered a problem."

Lin Xiao said with a smile.

As researchers, they all understand.

Ma Weimin tapped his head and said helplessly, "Isn't it? This time there is indeed a problem."

At this moment, Ma Gaoliang smiled and said, "Tell me, what's the problem? See if I, a person who doesn't study as much as you, can understand me."

Ma Weimin smiled and said, "It's actually a problem of fluid mechanics, but this situation is a bit strange."

"strangeness?"

"Well." Ma Weimin said: "You should also know that I have made a superconducting magnetic fluid thruster now, right? It was originally as planned, replacing the superconductors in the previous superconducting magnetic fluid thrusters with CCD-I That’s enough, just modify other structures by the way, it looks very simple, but problems appear in the actual use process.”

"what is the problem?"

"When the running time exceeds an hour or so, the water flow in the channel will suddenly become turbulent, resulting in a significant reduction in propulsion force and a relatively louder noise. I am very puzzled by this."

"Obviously, the DNS method has been tested many times, and basically there is no problem, but this happened."

Hearing Ma Weimin's question, everyone present was also puzzled.

Will the water flow suddenly become turbulent?

Why is that?

Chapter 348 A Strange Phenomenon

"why is that?"

Even Lin Xiao was quite surprised to hear the news.

After an hour of operation of the magnetic fluid channel, the water flow will be disturbed?

Ma Weimin shook his head: "I don't know either, so I'm struggling with this."

"During the process of DNS (direct numerical simulation), I did not find this kind of situation at all, and it turned out that this kind of situation appeared in the actual process."

Shu Qingzong asked, "Is it all an hour?"

"It's not all one hour, some are one hour, some are more than one hour, even two hours, three hours, six hours are possible, basically all happened after one hour." Ma Weimin said .

"Haven't you discovered it before? I remember that there was a team in China who conducted a model study before?" At this time, Director Ma said that the approval of funds for these experiments is also related to his department, so he has also heard of it. : "I remember that it has been running for many days? There is no problem."

Ma Weimin said: "Their pool is self-built, and it's not a submarine, it's just a boat. My model tests are basically carried out in a large experimental pool, which completely imitates the ocean environment. The conditions of water pressure and current Basically different."

"That's it." Ma Gao nodded, expressing his understanding.

After that, he didn't say any more. After all, in front of the three professors around him, although he still has a doctorate degree, if he counted it, he really didn't read as many books as these three professors.

Ma Weimin rubbed his eyebrows, sighed and said, "I have a feeling that this is a new discovery, maybe it has something to do with something hidden in the NS equation."

Shu Qingzong followed suit and shook his head: "According to what you said, it is impossible to really solve the NS equation."

Ma Gaoliang also said with emotion afterwards: "Navier-Stokes equation, how difficult it is to solve this thing, who can solve it?"

However, when Ma Gaoliang said these words, the three of them were taken aback for a moment, and then they all looked at Lin Xiao who was lowering his head to eat.

Lin Xiao took a mouthful of rice, raised his head and said, "Don't say it, the dishes made by this master are quite delicious, I recommend you..."

As a result, after raising his head, he was stunned for a moment, looked at those three pairs of eyes, recalled the topic they had just talked about, and suddenly said speechlessly: "Hey, don't look at me, that's NS equation, I don't know how to do it what?"

"Hey, Professor Lin, let's stop talking about this, you have already solved a Hodge conjecture, isn't it just a NS equation! Fuck him!"

Ma Gaoliang hugged Lin Xiao's shoulder with a smile and started talking.

Lin Xiao suddenly rolled his eyes, "What do you mean, 'isn't it just a NS equation'? Just kidding, these are the seven major problems of the millennium, okay, give you a pen, and you can do it?"

Ma Gaoliang laughed, "Well, forget it."

However, Ma Weimin next to him said at this time: "Professor Lin, no matter what, I still need your help. We are having trouble with direct numerical simulation. The high probability is that direct numerical simulation still cannot perfectly explain the motion of fluid. After all, direct numerical simulation Simulation still has certain limitations, and if we can know the existence and smoothness of the solution of the NS equation, then it will not only be very helpful for my research, but also for the research of other things. .”

Then he also said with a smile: "Of course, I'm not a force to be reckoned with. After all, it's NS equation. If Professor Lin can give me a little help, not to mention unraveling it, a little help is fine."

"If you want me to say, Academician Ma, you just invite Professor Lin to join your research group."

Shu Qingzong next to him laughed.

Ma Weimin's eyes brightened, "Yes, Professor Lin, do you want to come to my research group?"

Hearing this, Lin Xiao thought for a while, then nodded, and said, "Okay, Academician Ma invites me, of course I will come."

"Of course, I can't promise you that joining your research group will help you solve the problem."

"Haha, who doesn't know that Professor Lin has great powers, you can solve any problem in your hands, and it won't take long. I'm looking forward to it."

Ma Weimin laughed.

No matter what, it is obviously a huge help for Lin Xiao to join his research group.

Maybe at that time, this problem that has troubled him for a long time will be solved because of Lin Xiao's joining?

Ma Gaoliang and Shu Qingzong next to him also laughed, and Shu Qingzong said enviously: "Old Ma... I'm talking about Academician Ma, you are so lucky, you can get such an awesome meal here. A boost, I'm also suffering from a headache right now."

"Oh? What's your headache?"

"It's not the microwave weapon, hey, forget it, it's not easy to do, let's eat, let's eat, my food is cold."

The other three all smiled, scientific research, it is a common thing to encounter problems, so they basically didn't care, and continued to eat.

And just like that, the meal is over.

And since Lin Xiao wanted to join Ma Weimin's project, the two of them naturally didn't waste time. After dinner, Lin Xiao went to Ma Weimin's laboratory.

The superconducting laboratory is quite large, and at the same time, many places are considered, especially the application research of room temperature superconductors, so Ma Weimin's laboratory is also quite large.

After entering, you can see that there are about a dozen people working on the corresponding work. In addition, there are many models in the middle of the laboratory, and there is a magnetic fluid thruster made by CCD-I. frame.

Looking at this big guy, Lin Xiao couldn't help feeling emotional.

He didn't even know that this place had been tossed like this.

At this time, Ma Weimin clapped his hands and made everyone in the laboratory look at him. Ma Weimin said with a smile: "I'm here to tell you a good news. Director Lin has officially joined our research group. Are you still welcome?"

Hearing this, and looking at Lin Xiao who was standing next to him, everyone in the laboratory applauded enthusiastically: "Welcome, welcome! Warmly welcome!"

Just kidding, this is the living Lin Shen.

Although they work in the Dingguang Research Institute, because they have been staying in the research institute, they rarely see Lin Xiao. At this time, not only did they see Lin Xiao, but they were even able to work with Lin Xiao. They immediately became happy .

Lin Xiao also smiled and nodded towards these people, and then went to the experimental platform with Ma Weimin.

"Professor Lin, let me show you our recent water experiment and DNS simulation first."

"Our launching tests are all in Wushi. I'm from the Naval Engineering University, and our large-scale experimental pool is also carried out there." Speaking of this, Ma Weimin said: "So if we want to experiment, we may have to go to You should be able to go to Wushi, right? Of course, if you can’t, we can do it too.”

Lin Xiao nodded: "Well, this is no problem."

"That's good. Of course, if you have something that causes inconvenience, it doesn't matter."

Ma Weimin smiled.

"Row."

"Ah."

Ma Weimin nodded, then stopped talking nonsense, and showed Lin Xiao the relevant data of their original experiment.

The first is direct numerical simulation.

Direct numerical simulation of DNS is to directly substitute the predetermined values ​​into the Navier-Stokes equation, and then perform a large number of calculations on the computer to finally simulate the motion of the turbulence model.
