Chapter 75: Xu Qingzhou is really not human!

Time passed gradually. The noon sun passed through the leaves, leaving mottled tree shadows on the lawn outside the window. The breeze blew, and two withered leaves fell with the wind.

Throughout the morning, Xu Qingzhou completed the preliminary organization of the existing data and used Python to complete the cleaning work of the latest set of sample data.

During this period, Gong Yunfei came to see it once, but seeing Xu Qingzhou was absorbed, he didn't disturb him.

"Junior, take a break, go eat."

Hong Yayu's voice pulled Xu Qingzhou back. Turning his head, he saw Hong Yayu had already taken off her work clothes.

Xu Qingzhou stretched, and said: "Senior sister, I want to take these data back and study them slowly."

Hong Yayu nodded, pointing to the hard drive next to her, "You can copy it here... but the calculation volume is very large, which is more demanding on the computer's configuration."

Freshmen enter school. Besides military training, the second thing is the club.

"Little Qiong?" The voice was clear and cold.

Zhang Qiong reacted quickly, found an excuse, and said: "Right, rice bowl. I suddenly want to eat the same as you guys."

"Didn't see clearly who it was." Xu Qingzhou was a bit helpless.

The campus atmosphere is very lively. The Yan Garden Triangle held a club recruitment activity, which was in full swing, commonly known as the Hundred Clubs War. Xu Qingzhou really had no interest in this.

Using the sigmoid function (logic function) to describe the change of resistance with temperature, this is a continuous but constantly increasing function. It has an "S" shaped curve, which can well describe the transition from normal state to superconducting state.

Xu Qingzhou just said why Hong Yayu would suddenly ask him to eat. It turned out to be sending care. It really is just like what Gong Yunfei said. Don't look at this senior sister being cold, she is quite good at caring for people.

"You didn't go to get the rice bowl?" Song Yao was puzzled. Zhang Qiong's expression was too strange. At first, it was fierce, like a bad person, and then it was like she did something bad and was discovered.

This is already the second one! One Song Yao is not enough, recruiting flowers and attracting butterflies all day. It's only been a few days, and another girl has been changed! Zhang Qiong gritted her teeth, opened the photo just now, stared at the boy in the photo, and her eyes sank. Xu the Scumbag, you wait, I will eventually make you reveal your original shape and die without a burial place!

Xu Qingzhou turned his head to look again, feeling inexplicable, or, could it be that he was already so handsome that girls needed to sneak photos? Neither of them took the matter just now to heart. After eating, they returned to the laboratory directly.

Hong Yayu was eating, not paying much attention to who this person was, just adding: "She was taking pictures of us just now."

"I also want beef noodles." Xu Qingzhou nodded with a smile. The beef noodles in Xue Wu canteen are indeed good.

Consequently, Song Yao and Zhong Ruotong arrived at the seat first to wait for Zhang Qiong.

Xu Qingzhou turned his head suspiciously, and saw a back disappearing around the corner like fleeing for his life, which seemed a bit familiar, but he couldn't remember who it was.

"Today, let's go eat beef noodles at Xue Wu canteen." Hong Yayu finished speaking, adding: "Of course, you can go eat other things."

"Right."

After a while, Zhang Qiong brought the tray over, sat beside Song Yao, and couldn't help asking: "Little Yao, why haven't I seen you go find Xu Qingzhou these two days?"

Zhang Qiong felt a pain in her heart, sighing secretly, thinking that it must be busy, and busy dating other girls!

"It's a good start in the morning, and the follow-up is much smoother."

"Is this your first time participating in a research project?"

Hong Yayu didn't talk much, nodded lightly, and took Xu Qingzhou across the Zhongguancun North Street nearby.

Hong Yayu suddenly looked behind Xu Qingzhou and asked: "That girl... do you know her?" At the same time, at the corner of the restaurant, Zhang Qiong patted her chest, secretly saying it was dangerous, almost discovered.

"Senior sister, what are we going to eat?"

Song Yao was a bit distressed, saying: "I don't have any clubs I want to join."

She tilted her head and glanced, finding that the two people had already left. Xu Qingzhou is eating with a girl again!

!.

After finishing the paper, he took out the experimental data.

"Hmm, when you were looking at the data just now, he went out to eat."

"He..." Song Yao's chopsticks paused, her expression slightly lonely: "He has been very busy recently, I don't want to go disturb him."

Hong Yayu nodded slightly, showing an expression of "you have a good eye", walked a few steps, and asked again: "How do you feel after looking at the experimental data today?"

At 11:00 PM, before the administrator drove people away, Xu Qingzhou had already initially established a set of simple mathematical models.

"Good." Zhang Qiong nodded with a smile.

"Then hurry up and go. We'll wait for you over there." Song Yao pointed to an empty seat on the side.

"Ah?" Zhang Qiong was startled, suddenly put her phone behind her back, and looked at the beautiful girl opposite nervously.

A good start in the morning, and the follow-up is much smoother.

"Senior Brother Gong still has to watch the experiment?"

"During this time, many seniors have come to invite Little Yao, even I have a headache." Zhang Qiong complained.

When the two were almost finished eating, the canteen gradually became crowded. At 12:10 PM, the people who finished class had arrived.

"Have you guys thought about what club to join?" Zhong Ruotong mentioned another thing.

Little Yao's emotional experience is too little, and she was easily deceived by Xu the Scumbag. Looking at the beautiful girl beside her, she felt more and more that Xu Qingzhou was not human, and could bear to deceive such a good girl.

The two chatted one after another, and walked into Xue Wu canteen before class ended.

"Hmm, I know." Xu Qingzhou nodded. His computer cost 15,000, and processing some data was no problem. After connecting the computer to copy the data, he and Hong Yayu walked out of the laboratory.

Hong Yayu really didn't have any idol baggage, eating more than Xu Qingzhou: a bowl of beef noodles, three fried buns, and even ate a crispy flatbread.

He said: "It's harder than pure math problems, but I already have some ideas."

"You are very amazing..."

At the same time, an equation model depending on magnetic field strength and temperature was established.

Then fit the model parameters and bring the data into the verification.

Using Python, calculate the critical current density under magnetic field strength: def critical_current_density(b, j0=1e10, bc=10, n=2): After all, it is just a preliminary model, so the first verification has many discrepancies with the actual measurement, and subsequent data needs to be continuously brought in to optimize and improve.

This is also why Professor Zhao Shengwen asked for help from the School of Mathematics. Just a small model requires complex calculations, let alone a complete big model that can describe the performance of niobium-titanium alloy.
