"It's okay, our school library has an electronic reading room with computers in it, but it may not be convenient to use."

Xu Chuan immediately hit the idea on the library's electronic reading room, but soon felt that it was inappropriate.

Although the library has an electronic reading room, there are computers that can be used, but the system will be automatically restored after each shutdown, just like the computers in the Internet café, the software and materials installed on it will be lost.

After thinking about it, he continued: "Forget it, you can use my computer, it's better than the computer in the electronic reading room, and you don't have to reinstall the software every time to import data or something." ”

Liu Jiaxin shook her head and politely refused: "Then you don't have it yourself." ”

Xu Chuan: "It's okay, I'll just sort out the data, but then you will have a harder time, and you have to do the work of writing code and building models, so I will be easier." ”

"It's okay, I'm not afraid."

"Then it's decided, this afternoon at two o'clock in the school library room 401, there is usually more empty, ten days are a bit tight, the workload is a bit heavy, senior sister, you are okay, right?"

"Well, I'm fine, but you don't have a computer, can you?" Liu Jiaxin looked at Xu Chuan with some concern.

"It's okay, it's just a matter of sorting out the data, I have a replacement."

Xu Chuan waved his hand and said, if he simply sorted out the data, he would use a tablet + keyboard to do so.

However, if the modeling work is all undertaken by the senior sister alone, the workload will indeed be much larger.

After all, he was originally going to write it together with two people, so that it would take about three or four days to get it done.

Now it's all written by the senior sister alone, I'm afraid it will take a week.

But it's okay, if the modeling work is all done by one person, the contribution will be a lot greater, and when the scientific research project of tungsten diselenide is completed, the senior sister can get more bonuses.

Anyway, he doesn't have much need for money at the moment, and if he needs money, he can just write two SCI papers.

If you are in an area with a heavy impact factor such as District 1 and District 2, the school's bonus is still quite large, and according to the impact factor and importance, one article can have tens of thousands or even hundreds of thousands.

Like the weak Weyl_Berry conjecture he proved before, there will be additional rewards for schools and provinces and cities after the proof.

But that's probably what he can do.

Who dares to say that they can casually brush SCI papers?

His mentor Chen Zhengping didn't dare to say that.

.......

At two o'clock in the afternoon, Xu Chuan came to room 401 of the library with his computer and some materials.

This is not a quiet reading room, but an open area suitable for group discussions and group work, and it is not forbidden to talk, and it is normal to be very active even when people are loud.

Xu Chuan has met strange people here before, when he and his senior brother were studying projects here in their previous life, there was a stinky little girl at the discussion table opposite, and a dog-faced boyfriend sitting next to him, the two were also arguing, and from time to time they scolded loudly.

Then the group was discussing, and suddenly the girl shouted at them: "Can you be quieter?" I've been holding up for a long time! This is the library. ”

He was speechless.

Glancing at the reading room, Senior Sister Liu Jiaxin had arrived, and she was sitting in the corner reading a book.

Xu Chuan walked over and took out the computer and materials from his backpack: "I'm sorry to keep you waiting, senior sister." ”

After whispering hello, he turned on his computer, which was not turned off, and connected to the power and wireless signal in the reading room.

NTU was one of the first universities to digitize its library in real time, so now there are wires and sockets under each seat in the reading room in the library, and you can also connect to WiFi to browse e-books at any time.

"No, no, I just arrived." Hearing the voice, Liu Jiaxin raised her head and saw that it was Xu Chuanhou who responded in a low voice.

"I have MATLAB, Lingo, Cplex, python, Mysql database and other programming software installed on my computer, do you want to see if there is anything missing, if you don't need it, you can download it yourself."

"After confirming that the software is fine, I will start to explain to you this work." Xu Chuan prompted.

"yes, okay."

Now that the decision has been made, the senior sister did not hesitate too much, and began to check it after taking Xu Chuan's computer.

On the side, Xu Chuan began to toss his own things.

He only has one computer, but he still has a tablet in his hand, which he bought after participating in the IMO and IPHO competitions and went back to China to accompany his sister Xu Xiao.

After all, it was his promise, and he simply bought a three-piece set of mobile phones, computers, and tablets for Xiaoxiao at one time, and he also bought a tablet himself, but he didn't use it much.

This will be just right, and a wireless mouse and keyboard can be used to organize data.

After a while, after almost tossing on his side, the senior sister's side also checked about it.

"Is there something missing?" Xu Chuan asked.

"There's one less SPSS." Liu Jiaxin whispered: "I'm already down, I'll be fine right away." ”

"Well, okay, then I'll tell you about the goal and core of this modeling."

Xu Chuan nodded, and continued: "The core of this modeling is mainly to establish a dynamic discrete model to calculate temperature, pressure, raw material concentration, and reducing agent concentration..... and other effects on the tiling of tungsten dielenide nanosheets in the experimental material. ”

"The core mathematical formulas have been simplified on my side, and the experimental data and the corresponding mathematical symbol relationships are all here, you can take a look first, and ask me directly if you have any questions."

Liu Jiaxin nodded, took the materials and manuscript paper from Xu Chuan's hand and looked at it.

Xu Chuan continued his work on the side, two days ago he preliminarily sorted out the data, but there are still some things that can be further improved, and after the mathematical model comes out, various results can be directly calculated.

.......

In the library, time slipped away little by little, and in the process of continuous running-in, Xu Chuan unexpectedly found that this senior sister's talent in mathematics was quite high.

He can understand a lot of things once, and he can talk about some difficult points again, not to mention his talent in mathematical modeling.

She can accurately and quickly investigate and understand the information of the object, make simplified hypotheses and analyze the internal laws, and then express them in mathematical symbols and language.

She knows the core of mathematical modeling very clearly.

For Xu Chuan, this is good, he doesn't have to waste time on these issues, he just needs to be responsible for sorting out the data.

With the core formulas and data already sorted out, the modeling work is progressing well.

In less than a week, it took only four days, and on the afternoon of the fifth day, the senior sister taught him a complete dynamic discrete model.
