Great Country Academician

With the optimized mathematical model, Xu Chuan found Gao Hongming, who was arranged by the science and technology department to be in charge of the overall work, and explained his intention.

"No problem, I will report to the above."

"However, do you have any requirements for the supercomputing center you are applying for in terms of performance?"

Hearing that it was to test the mathematical model of plasma turbulence, Gao Hongming quickly agreed, and asked about the requirements by the way.

Xu Chuan smiled and took out a piece of cardboard from the backpack behind him, handed it over, and said, "The performance requirements are all on top. In terms of time, the sooner the better, I will trouble you, Gaoting."

"No, no, Academician Xu, please don't say that. It is my duty to cooperate with your work and ensure your needs. I will report this matter right away, and I should be able to give feedback in the afternoon."

Gao Hongming took the jammed paper, glanced at it and carefully put it in his pocket.

For him, whether it is the controllable nuclear fusion project or the request of Academician Xu, it is the key point.

The former is a national key project, let alone the latter.

Now that the two are superimposed together, it can be said that as long as there is a request, the most direct and fastest way will be used for reporting.

For other projects, applying for a national supercomputing center requires you to fill in a lot of information forms, and you have to review the model for application processing or the data that needs to be calculated. The various queuing processes go down, and it takes two or three months. The time will not come down at all.

Hearing this, Xu Chuan nodded and said with a smile, "In that case, I'll wait here."

For half a day, he could still afford to wait.

At the foot of Qixia Mountain, strolling around the controllable nuclear fusion industrial park, Xu Chuan once again experienced what is called "Hua Guo Speed".

In just a few months, buildings have been built here according to the plan.

Although the core area is still dealing with the underground area, the buildings in the surrounding living park and research park have all been built.

According to visual estimates, in two or three months, the research team responsible for the controllable nuclear fusion project will be able to relocate from the Xianlin campus as a whole.

Of course, many of the equipment needed for the experiment are being procured and manufactured.

After all, controllable nuclear fusion is a super project, which involves equipment, such as the plasma orbit of the reactor, external field coils, water-cooled divertors, and heat generators for power generation. It cannot be handled by one or two or even one or two hundred companies. .

This kind of super project requires the power of a country, and it must be fully supported by a big country to progress smoothly.

Xu Chuan has never been worried about the construction of the park. For an infrastructure maniac, when the construction of the park is agreed to be completed, it must be completed before that point.

But it is not necessarily the case when it comes to reactor components.

Those parts with extremely high precision, not to mention domestic, even the whole world, there are not many manufacturers that can manufacture them.

Therefore, after the verification of the mathematical model is completed, he has to find a reactor in China to test it to see if it can really successfully complete the control of ultra-high temperature and high pressure plasma turbulence as in the verification calculation.

At around three o'clock in the afternoon, Xu Chuan, who was discussing construction issues with Qi Zhongxing in the park, received good news from Gao Hongming.

"Academician Xu, I have already communicated with major supercomputing centers about the supercomputing center application you need. Currently, there are two supercomputing centers that can spare part of their computing power to complete the task within a week."

"The first one is Yangcheng Center, which is equipped with the "Tianhe-2" supercomputer and related systems."

"The second is the Gucheng Center, where the "Tianhe-1" supercomputer and the "Tianhe-3" prototype system are deployed."

"I've printed out the information related to these two supercomputing centers, can you take a look first?"

While speaking, Gao Hongming handed the folder in his hand to Xu Chuan.

After taking the folder, Xu Chuan took out two documents from it.

The first information is the supercomputing center in Yangcheng. This supercomputing center is located in SYS University, a university city in Yangcheng. It has the "Tianhe-2" supercomputer independently developed by Huake University.

The peak calculation speed is 5.49×10 to the 16th power per second, and the continuous calculation speed of double-precision floating-point operation exceeds 3.39×10 to the 15th power per second. It is mainly used in high-tech industries and modern service industries, digital city construction and scientific research fields. .

The second information is the supercomputing center of Gucheng Center. This supercomputing center is located in the BHX district of the ancient city. Compared with the supercomputing center in Yangcheng, its computing performance is a little weaker.

But it has a unique advantage, that is, it is mainly used in aerospace, meteorological research, controllable nuclear fusion, civil engineering design analysis, high-end equipment manufacturing and other fields.

For the calculation and research of fluid mechanics, it has advantages that other supercomputing centers do not have.

Xu Chuan looked through the materials and decided where to do the experiment.

After handing back the documents in his hand to Gao Hongming, he said, "Gaoting, please apply for the supercomputing center in Gucheng. As for the time, the sooner the better, just call me after the application is completed. I will bring Followed the model in the past."

In terms of computing power, a national-level supercomputing center is enough for him.

Even the Gucheng Supercomputing Center, which is relatively backward in performance, is only relatively backward compared to other national levels.

It is enough to divide some computing cores casually.

And it has been calculating and researching fluid mechanics all year round, which is an advantage that other supercomputing centers do not have.

With the help of this advantage, perhaps he can optimize the only image model in Gucheng.

Although it may not be very large, don’t underestimate this optimization. For a mathematical model with countless calculation variables, even an optimization of only one in ten thousand can save a lot of computing resources in the final calculation.

Gao Hongming nodded and said, "Okay, I'll go there with Academician Xu when the time comes."

After dealing with the matters related to the mathematical model, Xu Chuan did not stay in the nuclear fusion industrial park. He went straight to Chuanhai Materials Research Institute.

In October, he assigned the institute the task of researching superconducting materials and carbon-based materials.

There is no requirement that they can produce any results, but that they are required to continue to experiment, which is equivalent to spending money on experimental data.

No way, compared with those old research institutes or laboratories with decades of material research experience, the Chuanhai Materials Research Institute has too little experience.

If it is another laboratory that has been studying superconducting materials for more than ten years, it can be said that there is no need to spend so much money on experimental data.

The experimental data accumulated over time is enough for him to use.

But every piece of experimental data is the most important information for the research institute or laboratory, and it is the root of the laboratory, and it is impossible to sell it to others without special circumstances.

So Xu Chuan can only exchange experimental data by exchanging money for time.

Summarizing experience through trial and error and finding a way to the key point is the only way for all materials science experiments.

The computational simulation model he developed is indeed a promising method, but in the end it has to be implemented in specific experiments.

No matter how awesome mathematics is, unless you are an omniscient and omnipotent god, it is impossible to completely replace all experiments

It can only be said to help you introduce some time or unnecessary detours.

Knocking on the door of the office, Brother Fan Pengyue, who is in charge of the Chuanhai Materials Research Institute, is dealing with work. When he saw Xu Chuan coming, he stood up to greet him with a smile.

"Academician Xu is here, the humble house is full of splendor."

Xu Chuan rolled his eyes at him, and said, "I'm talking like a guest."

Fan Pengyue laughed and said: "You haven't come here a few times this year, and the shopkeeper is too straightforward. I'm not afraid that I will swallow up your laboratory with other people. Anyway, I have invested hundreds of millions of dollars now. "

Xu Chuan glanced at him and said, "You can try it. Even if you succeed, it's only 100 million yuan, which is not much to me."

Fan Pengyue smiled and said: "Forget it, when the time comes, the instructor will kick me out of the teacher's school and it will be over."

"Besides, in China, where can I go if I'm greedy for your things? A giant at the academician level of the two academies, I'm afraid I will be pointed at my head if I can't even walk out of this office."

Xu Chuan shook his head and said: "Don't be poor, I'm here to see how the experimental research arranged before is going. If there is enough data, I will start to conduct research on copper-carbon-silver composite superconducting materials. Research."

When it came to business, Fan Pengyue stopped playing around. After thinking for a while, he said: "Two months is still a bit tight. At present, there are eleven groups of experiments on copper-carbon-silver composite materials. About 500 sets of experimental data."

"As for the two pieces of graphene and carbon nanotubes, because the equipment was only shipped in the middle of last month, less than 50 sets of control experiments have been done so far."

Xu Chuan nodded and said, "The efficiency is not bad. I guess you must have worked a lot of overtime."

For the exploration experiment of copper-carbon-silver composite materials, it takes quite a long time to do each group, ranging from a few hours to a day or two.

"Yes." Fan Pengyue nodded, and continued: "In the past two months, I have indeed had a lot of overtime."

Xu Chuan: "It's okay to work overtime, as long as the wages for days off and overtime are paid according to the standard."

Fan Pengyue nodded and said: "Don't worry about this, there will be no missing buttons."

"I don't look at the overall data. Is there any sorted data?" Xu Chuan continued to ask. Five hundred sets of experimental data can generate a lot of data.

Most of these data will be repeated or discarded, and only a small part of the data may bring some hope of leading to the correct synthesis.

It is also troublesome to select useful data from these data, including how to analyze and process these data and bring them into the material calculation model. Work.

Fan Pengyue nodded, and said: "Of course, the data of each experiment has been saved, and then the possible suitable methods and paths will be selected through analysis. As for the basic data, those have already been entered into the material calculation model."

"At present, the most optimized route is to use nano-synthesis technology to composite copper-carbon-silver materials through inert gas protection and then sintering and other treatments. After a series of screening and purification, the chemical deposition method is used on the base layer. It is deposited in the form of a two-dimensional thin film, forming a crystalline structure."

"This two-dimensional thin film sheet is superimposed and then cryogenically frozen through liquid helium, which can realize the characteristics of copper oxide low-temperature superconducting materials."

"This is the first to achieve ultra-low temperature superconductivity of copper-carbon-silver composite materials."

"As for other experiments, this potential has not yet been demonstrated."

Hearing this, Xu Chuan was a little surprised, and said, "There is a breakthrough so soon?"

Fan Pengyue nodded and said: "Well, it has been tested. At a temperature of 43.5K, this copper-carbon-silver composite two-dimensional thin film material has the characteristics of a superconducting material."

There was a hint of interest in Xu Chuan's eyes, and he said, "Go and see this first, and also give me a copy of the detailed information on this route and the information of the person in charge."

To be honest, he was a little surprised that Chuanhai Materials Research Institute could explore a route to ultra-low temperature superconductivity of copper-carbon-silver composite materials so quickly.

Moreover, this route is very close to his later research on copper-carbon-silver superconducting materials, which surprised him even more.

Even if he gave a research direction at the beginning, it was only a vague path.

Copper-carbon-silver composite materials, there are countless synthesis methods, and there are also countless material ratios.

If there is a slight deviation in the synthesis process, two materials with greatly different properties may appear.

In two months, he was able to explore a relatively correct path on this vague path, which shows that this researcher is quite capable.

Of course, there is also a certain possibility that a blind cat ran into a dead mouse, luckily took the right route, but luck is actually a part of strength in materials science.

Sometimes if you are lucky, you can really go through a very smooth route to the end, and directly synthesize the required materials.

But the probability of this is very low, and it's almost the same when Senior White comes.
