Chapter 81: Senior Gong expresses that he is under a lot of pressure

Xu Zhengyang is the only one in the dormitory; Kong Xianbo is at a student union meeting, and Zhai Ziqiang has gone to the Literature Club to participate in an activity.

Xu Zhengyang, that guy, is playing games. Xu Qingzhou finds it noisy, so he takes his computer and goes to the study room, opens his computer, and reads a paper on the application of niobium-titanium alloy in MRI.

The mathematical model is already finished; there are only some minor corners that need correction. There is no rush for now; he needs to wait for new data to perfect it.

Xu Qingzhou originally only intended to read the paper, but after finishing it, he discovers that some other things could seemingly be added to the model.

On Monday, there was a night rain. In the morning, the clouds parted and the rain stopped. The sky was deep blue, with only a few pure white clouds hanging on the horizon. Sunlight poured down, the trees on the ground were damp, the puddles on the ground reflected the light, and several figures late for class hurried past.

The morning is Professor Gu Zhizhong's class. Xu Qingzhou reasonably skips class and goes directly to the laboratory. He had originally planned to sleep early last night, but while working on the model, he unknowingly worked until two in the morning.

Physics Department Laboratory.

Then there is Senior Gong, who is rubbing his chin, trying hard to look like he is thinking, but he always feels that he is just as confused as she is.

Zhao Shengwen opens the computer, checks the model, inputs the data, performs the simulation, and after comparing the data, he is surprised, "This model... is very good."

"Good method." Zhao Shengwen is incomparably amazed. Judging from Xu Qingzhou's application of these equations, his physics foundation is very solid.

The graduate stage is different from the undergraduate stage. In the undergraduate stage, it is basically the address of seniors. By the graduate stage, everyone has the same teacher and is considered to be from the same school.

Wang Wei and Hong Yayu are a bit better, but some points are still quite obscure, and there is no time to think carefully.

Writing to one of the steps, Zhao Shengwen interrupts: "Eh, the N-S equation is different from the usual calculation method."

Ren Xiaoling comes back to her senses and hurriedly shakes her head, "You sit down first, I will finish cleaning up immediately."

Zhao Shengwen also goes from initial amazement to serious thinking, sinking into the calculation.

Looking at Xu Qingzhou, Ren Xiaoling cannot help but secretly admire him.

"Ah? You are Xu Qingzhou?" Ren Xiaoling is stunned for a moment. Previously, Gong Yunfei mentioned that there was a junior who was also in the project, not the kind who does odd jobs like her, but the kind who truly participates in the project.

Xu Qingzhou nods, sits down at the desk, opens the computer, and seeing this senior staring at him, he takes the initiative to say: "Senior, shall I help?"

"Junior, awesome." Gong Yunfei clicks his tongue in amazement on the side.

So young, he can participate in Professor Zhao's project as a freshman.

A surprised expression also appears on Hong Yayu's face.

"Yes, for this Navier-Stokes equation, I used the Fourier transform method to simplify it, and it is much simpler to calculate."

!.

Xu Qingzhou writes very quickly. During the calculation process, he discretizes the heat conduction equation into a solvable system of linear algebraic equations.

Xu Qingzhou is startled by her enthusiasm. After coming back to his senses, he smiles and says: "The generation gap is wrong. I am Xu Qingzhou, a '14 freshman. I should call you Senior." At this time, Zhao Shengwen also finishes his work and walks in with Wang Wei and the other two, "Little Xu is here."

In half an hour, Xu Qingzhou finishes speaking and stops to look at Zhao Shengwen and the others.

Ren Xiaoling takes a small notebook and originally wanted to take notes, but she soon starts to not understand.

Xu Qingzhou sketches on the draft paper, electric field theory, fluid mechanics... various knowledge is at his fingertips.

He specifically instructed Wang Wei to help Xu Qingzhou yesterday, but hearing Wang Wei's reply, he said that this little guy wanted to do it himself.

Am I really that bad? Ren Xiaoling is on the verge of tears. She carefully observes that Professor Zhao nods slightly, occasionally raising questions, and Wang Wei and Hong Yayu fall into deep thought, thinking about the steps.

There is an extra girl in the office, wearing a meatball bun hairstyle, holding a rag in her hand, wiping the table. Her expression is calm and meticulous. Even though she is just wiping a table, she has created a sense of ritual.

Of course, thinking about it later is definitely fine, but Xu Qingzhou speaks too fast, and some places turn so smoothly that he simply cannot react.

"When considering the induced electromotive force caused by the change in magnetic flux, it is necessary to consider the role of the electric field and calculate the influence of the electric field through the equation 【\vec{b}\cdot\mathrm{d}\vec{a}=0】."

Professor Zhao's project is one of the best in the institute. This junior can get in as a freshman; he must be a big shot.

Seeing Xu Qingzhou come in, this person is startled and introduces himself: "Hello, Senior! My name is Ren Xiaoling, a '12 physics major student. Please give me more advice, Senior!"

"Professor Zhao." Xu Qingzhou smiles and greets him, stands up, and gives his seat to Zhao Shengwen: "The model is ready, you can take a look."

"In the experiment, you can try to control the low-temperature thermostat between 7.5-8k. Perhaps there will be unexpected gains."

Gong Yunfei is indeed a bit ashamed. He is not a mathematics major himself, and calculation is his weakness. Those formulas and the like are simply a disaster for him.

"Last night, I read a few papers in 'Physical Review Letters' and added some interesting things to this model."

Wang Wei holds the report paper and looks at the output values on it, feeling incomparably surprised in his heart. He originally wanted this junior to hit a wall and not be too young and arrogant, but he actually figured it out.

As he speaks, Xu Qingzhou pulls out an A4 sheet of paper from the table and calculates on it: "I added two functional models to the underlying model of Maxwell's equations and also added a few equations in fluid mechanics."

"Therefore, in the synthesis stage, heat treatment is carried out at a fixed temperature to make the Nb plate and Ti plate diffuse at the boundary, forming an NbTi solid solution alloy, and the remaining Nb or Ti after diffusion can also become pinning centers. Since Nb and Ti can appear in each NbTi layer, and their quantity and uniform distribution are guaranteed, it is conducive to the improvement of superconducting performance."

"Although the process is relatively tortuous, it still lives up to expectations." Xu Qingzhou says modestly. After a pause, he still says: "Actually, I had some thoughts last night. I don't know if you want to hear them." Zhao Shengwen says seriously: "Tell me your thoughts."

At 9:30 in the morning, Zhao Shengwen is busy with Wang Wei and the others in front of an instrument. Xu Qingzhou does not disturb them and walks straight to the office area on the other side.

Hong Yayu frowns and says: "But at 8k, the material completely enters the superconducting state. Is 7.5 too low?"

"This requires specific experimental proof."

Xu Qingzhou spreads his hands and says helplessly: "Compared to electromagnetism and materials science, I am more familiar with things in the quantum field. These contents are all calculated based on current data, just to provide you with a reference."

He indeed cannot guarantee that this line of thinking is definitely correct; after all, this is not something he is familiar with.
