Chapter 255: Do you want me to come and squeeze in your room?
Unfortunately, even if Xu Qingzhou lived for decades longer and was good at observing words and emotions, he would never have imagined that the aloof Song school beauty had fantasized about him "forcing" her several times.
Otherwise, we would have been unable to cooperate any longer.
The two walked back, passing by a milk tea shop, and bought two cups of iced milk tea. In Song Yao's words: "Exercise is to strengthen the body, not to lose weight."
As night falls, the orange light of the street lights lengthens the shadows of the two people, intersects them, and lengthens them again. Now, most colleges have entered the stage of suspension of classes for review exams.
The classmates were in a hurry on the way, and the campus was filled with a solemn atmosphere before the exam. Even the couples who could be seen sitting by the lake and making love to each other were mostly missing.
People like Xu Qingzhou and Song Yao who can go for a run, buy a cup of milk tea and stroll around the school leisurely are a bit special.
Achievement involves performance points and evaluation of excellence and awards.
Both Xu Qingzhou and Song Yao have no worries about these things.
The college realized that it was a waste of time for Xu Qingzhou to take the exam and directly exempted him from the exam.
Song Yao, ranked first in her major, had a much higher score than the second ranked student. While others were still reading freshman books, she had already seen the junior year textbooks.
"There is no news from Johns Hopkins University." Song Yao is more concerned about the proof of Polignac's conjecture than Xu Qingzhou, and she will look for any new progress every day.
“I guess we may have encountered trouble in the argument.” Xu Qingzhou remembered that six days had passed since Professor Stewart announced that he had proved his conjecture.
No news at all.
Song Yao bit the straw and asked: "Has your sieving method been adjusted?"
"It's pretty much the same. I introduced part of the double integral method a few days ago, and then I adjusted the counting function and deleted the redundancy."
Although Song Yao is not a mathematics major, But the two of them still often talked about Xu Qingzhou's affairs, and Song Yao didn't mince words. She listened carefully, nodding her head from time to time and saying "hmm".
Xu Qingzhou briefly explained the situation to his girlfriend and said optimistically: "In general, everything is going well so far."
Song Yao nodded slightly, took a sip of milk tea, and crystal Staring at Xu Qingzhou with bright eyes, he said: "Do you want to drink my cup?"
"Yes."
Xu Qingzhou nodded and exchanged milk tea with her. The arrogant guy obviously wanted to drink his cup, but he still wanted to ask if he wanted to drink it.
Song Yao frowned and took a big sip of milk tea, her eyes sparkling. She found another advantage of falling in love. You can taste two flavors of milk tea once.
Go home, take a shower, heat up the leftovers from lunch, and after eating, the two of them are busy again, one is working on the algorithm of the Quantum Research Institute, and the other is reviewing their homework.
Xu Qingzhou had originally said that it might rain in the next few days. Unexpectedly, at 1 o'clock in the night, there was a rumble of thunder outside the window. After a while, heavy rain came as expected.
There was a thunderstorm, and the two cats were so frightened that they crawled into Xu Qingzhou's arms.
Song Yao came out of the bedroom with sleepy eyes. She must have been awakened by the thunder and rain outside the window.
"Xu Qingzhou, you just said you would go to bed in half an hour."
"It's time to go to sleep." Xu Qingzhou was almost finished, he shut down the computer honestly, hugged Ermeow, and said: " It's thundering and raining. Are you a girl afraid?"
"No." Song Yao saw through this guy's thoughts. When he said he was afraid, he would probably say: "I'll go. I'll stay with you in the house."
However, to Song Yao's surprise, Xu Qingzhou nodded with a reassuring expression, which made her start to wonder if she was thinking too much.
"Then I'm relieved. However, you don't know that I have been afraid of thunder since I was a child. I am timid. Why don't you let me come to your room to squeeze in?"
"."
< br>"Look, the second cat is also afraid. You are the only bold one in our family, so it makes sense to take us in."
"It's okay, you go away."
Song Yao doesn't listen to Xu Qingzhou Nonsense, he snorted softly, took Ermiao away from his arms, turned around, went back to the house, and closed the door with a bang.
Xu Qingzhou sighed and moved into the Song school beauty's bed. This matter has a long way to go. In the master bedroom, Song Yao was sitting on the bed, also very distressed. Xu Qingzhou wanted to kiss her recently and especially liked to touch her.
It is said online that boys all need to be released.
So.
Song Yao lowered her head, her round feet moved uneasily, and her cheeks turned red. She quickly patted her chest again and spat in a low voice: "The devil wants to help him, just hold it in until you die!"
Fast forward to the new week, and it has been drizzling since Sunday.
Library.
Xu Qingzhou is comparing various data in the first week of the experiment. Judging from the first charge and discharge curve of the nano-silica powder negative electrode, the capacity loss in the first week is very large.
Lithium dendrites are a major reason, but the data fluctuations are still too large.
He frowned, organized the data, and brought it into the large analysis model.
Serial number 01
Silicon content (%): 50
Electrolyte type: A
C-rate: 0.5C
It takes four hours, Xu Qingzhou calculated the data and then wrote down the results.
1. Judging from the data feedback, the embedded lithium is captured by silicon atoms instead of the passivation film formed on the surface of silicon particles.
2. In addition to lithium dendrites, another important reason for the dramatic capacity attenuation of silicon anode materials is the corrosion of silicon by trace amounts of HF produced by the decomposition of LiPF in the existing electrolyte.
At the third point, Xu Qingzhou stopped writing. The computer showed that it was already 11:40 noon. He planned to go to the cafeteria to eat first. Song Yao was still in class, and because it was the last class of the semester , I want to eat with Zhang Qiong and the others after class.
It’s already dinner time, so it’s not even 12 noon yet. There are already more and more people in the cafeteria. It’s so crowded. Some people are eating and even want to take a look at the notebook next to them. After reading , took a few mouthfuls of rice, and looked again.
Sure enough, those who can enter Beijing University are basically the best in academics.
Xu Qingzhou ordered a two-meat and one vegetarian set meal, thinking about Professor Zhao's experiment.
Due to the pulverization of particles caused by its violent volume effect, new silicon atoms continue to consume Li, making it difficult to form a stable surface solid electrolyte film in conventional LiPF electrolyte.
After the silicon is nanosized, the lithium deintercalation mechanism of silicon nanowires can largely alleviate the phenomenon of active materials being crushed and detached from the current collector due to volume expansion during the cycle.
In addition, the one-dimensional silicon nanowire growth shape can also shorten the diffusion distance of lithium ions, which is beneficial to the rapid conduction of electrons.
However, judging from the current experiments, the effect is not good.
Xu Qingzhou was about to find a seat when he suddenly heard someone calling him. When he turned around, he saw Xu Zhengyang and Chen Shiqi.
Xu Zhengyang: "Damn, what are you thinking about? I shouted for a long time and there was no response."
"Some experimental things."
"Let's go, today On what day did I meet Lao Kong first and then you?”
“Is Lao Kong there?”
"Well, they are eating over there."
The number of people eating suddenly became four, and it became lively. Xu Qingzhou temporarily put aside the matter of lithium-ion batteries and chatted with his roommate whom he had not seen for a long time.
Xu Qingzhou's eyes swept over Xu Zhengyang and Chen Shiqi, "You two just came out of the library?"
Xu Zhengyang was hopeless: "Yes, we have exams on Thursday. Professor Gu’s mathematical analysis makes me numb.”
Tsk, Xu Zhengyang really needs someone to supervise him.
Xu Qingzhou couldn't help but clicked his tongue.
Seeing that Xu Qingzhou was very happy, Xu Zhengyang looked at him with resentment and protested: "Old Xu, can you have some sympathy?"
Xu Qingzhou was helpless: "I can't help it. I am more miserable than you. It’s hard to understand deeply.”
