"There's no need to rush it."

Xu Chuan said, turned on the computer, opened the mathematical model and checked it.

The model page is not so beautiful and decent, but the functions he asked for before have been done.

After initially checking the model and confirming that the basic functions are complete, Xu Chuan extracted a set of pre-calculated data from the experimental data, entered the model and clicked the output button.

With the calculation of the mathematical model, the cooling fan of the notebook also automatically spends up spinning, and the notebook, which was originally quite quiet, will 'buzz'.

For a laptop, even if it costs as much as a small million, even if it uses the latest Core i5 CPU core, it is not so easy to carry a somewhat complex mathematical model.

However, Xu Chuan didn't pay attention to the fact that the notebook was being carried under high load, just stared at the display screen, waiting for the data to complete the calculation.

Time passed little by little, and more than five minutes later, just when Xu Chuan thought that the notebook could not carry the model to run or that the mathematical model had a problem, the screen on the display screen jumped, and the calculation results came out.

Holding his breath and concentrating, Xu Chuan looked at the numbers calculated on the screen, and then glanced at the data that had been calculated before on the tablet.

That's right!

The first set of experimental data is completely correct!

The model is preliminarily judged to have no problems, can operate normally, and can also correctly calculate the numerical answers.

After confirming that there was no problem with the first calculation, Xu Chuan immediately entered the second set of different data from different experimental methods and clicked the output button again.

As long as the second set of data can be successfully calculated, then this mathematical model can be taken to the materials laboratory and handed over to Chen Zhengping.

Although the two sets of experimental data cannot guarantee that all functions and calculations are normal, it is worth applying for a small supercomputer or server to verify it in an all-round way.

As long as the verification can be passed, the manufacturing process of tungsten selenide nanosheets can be fully optimized through the data model.

Although it does not necessarily solve the collapse and rollup effects caused by van der Waals forces in the final tiling process, it can help Chen Zhengping optimize a large number of experimental processes, which in turn saves a lot of time.

As long as there is no problem, it can be said that this mathematical model alone, judging by Xu Chuan's experience, can at least help his mentor Chen Zhengping's team save nearly half a year's time.

This has always been the case in materials experiments, and the development of a material is generally a matter of continuous trial and error, and then recording experimental data and then making new experimental optimizations.

And then continue to accumulate data and experience.

Something like building a mathematical model to aid optimization is something that most labs want, but many can't.

Don't look at the two of them working together to complete the modeling work in four days, but this foundation is based on his huge mathematical ability.

Without him sorting out the data, simplifying the core mathematical formulas, and dealing with the mathematical symbolic relationships corresponding to the experimental data, modeling would not be so easy.

If I am an ordinary mathematics professor at NTU, it is estimated that I can't even sort out the data in ten days and half a month, let alone simplify the most important core mathematical formulas.

......

On the desktop, the time in the lower right corner of the computer monitor was beating little by little, and I still waited for about five minutes before the screen jumped.

Xu Chuan glanced at the calculated data, then looked at the answer on the tablet, and threw a "good job" look at the senior sister.

The senior sister looked at Xu Chuan and understood the meaning in his eyes, the corners of her happy mouth hooked a small amplitude, and she showed a smile for the first time.

After two verifications were completed, there was no problem with the data, and Xu Chuan found his mentor Chen Zhengping with the mathematical model.

"Done so quickly?"

Taking the USB flash drive, Chen Zhengping asked with some surprise.

He had given Xu Chuan ten days before, but he had already done it, and if he made progress and determined that the mathematical model could be made and completed, he could wait for half a month to a month.

Because the mathematical modeling used in large-scale experiments and the modeling problems above in the college student modeling competition are completely different concepts.

The latter problem is generally relatively simple, at most requiring a dynamic model and considering two or three factors.

However, the data of each experimental change in the former is extremely extensive and complex, and there are many factors and influencing conditions that need to be considered.

Just like his research and development of tungsten dielenide nanosheets, temperature, humidity, air pressure, current intensity, raw material concentration, time, reducing agent concentration..... And so on are variables.

To integrate these into a model, the complexity and difficulty are so much higher than that of college students' modeling competitions that I don't know where to go.

In five days, Xu Chuan was able to make a mathematical model, which had to make him doubt.

"Well, I'm afraid of delaying the progress of your side, the senior sister stayed up for a few nights to make it urgently, the model has been preliminarily verified twice, and the results calculated from different experimental data are correct."

"However, the performance of my notebook is limited, and it takes a long time to verify all the module functions, so I took the model over and saw if there was a powerful server or small supercomputer on your side, so that the verification speed would be much faster."

Xu Chuan explained, Chen Zhengping nodded suddenly, and said, "So that's the case, I've worked hard for you, I'll go to the application server to verify it." ”

"Well, that's troublesome teacher, you can always come to me if you have any questions."

Xu Chuan nodded, turned around and left the material research and development building.

The mathematical modeling thing is over, and the rest of the work has nothing to do with him.

Checking mathematical models and using mathematical models to find data and optimize the experimental process was his mentor's business.

Unless there is something wrong with the mathematical model, he needs to return it to the factory for repair.

However, this probability is not big in his opinion, and it can be checked by two different experimental data, which shows that there is nothing wrong with the core formula and code of this model, and it should only be a matter of time to pass the rest of the verification work.

If the performance of the requested server is sufficient, it will take about a day to verify the approximation.

Sure enough, as he expected, he didn't have to wait long, and after only a day, the phone was called to him.

"Hey, big brother."

Xu Chuan answered the phone, and the excited voice of his senior brother Fan Pengyue came over on the other end.

"Little junior brother, do you have time now? Take a trip to the Materials Laboratory Building. ”

"Well, okay, I'll go over now." Xu Chuan responded, estimating that the verification work should have been completed, and perhaps there was something new.
