Chapter 255: How about letting me squeeze into your room? Unfortunately, even though Xu Qingzhou had lived for several decades longer and was quite good at reading people's expressions, he could not have imagined that the cold and aloof school beauty Song had fantasized about him "forcing" her several times. Otherwise, we would have cooperated to the point where we couldn’t cooperate any more. The two walked back and passed by a milk tea shop and bought two cups of iced milk tea. In Song Yao's words, "Exercise is for strengthening the body, not for losing weight." As night falls, the orange light from the street lamps lengthens the shadows of the two people, interweaving them together and lengthening them again. Now, most colleges have entered the stage of suspending classes and reviewing for exams. Students were walking in a hurry on the road, and the campus was filled with a solemn atmosphere before the exam. Even the couples who were usually seen sitting by the lake and being affectionate with each other were mostly gone. People like Xu Qingzhou and Song Yao, who can go for a run and then buy a cup of milk tea and stroll around the school leisurely, are somewhat special. Results involve GPA, which is related to performance evaluation and awards. Neither Xu Qingzhou nor Song Yao have to worry about these things. The college realized that it was a waste of time for Xu Qingzhou to take the exam, so they simply exempted him from the exam.
Song Yao, the No. 1 in her major, had a much higher score than the No. 2. While others were still studying their freshman books, she had already read the junior year textbooks. "There's no news from Johns Hopkins University yet." Song Yao was more concerned about the proof of Polignac's conjecture than Xu Qingzhou, and would look for any new progress every day. "I guess we might encounter some trouble in the argument." Xu Qingzhou remembered that six days had passed since Professor Stewart announced that he had proved the conjecture. No news at all. Song Yao bit the straw and asked, "Have you adjusted the sifting method?" "It's pretty much the same. I introduced some of the double integral method a few days ago, and then I adjusted the counting function and deleted some redundancy." Although Song Yao was not a mathematics major, the two of them still often talked about Xu Qingzhou. Song Yao did not play along, but listened carefully, nodding and saying "hmm" from time to time. Xu Qingzhou told his girlfriend about the situation and said optimistically: "Generally speaking, everything is going well so far." Song Yao nodded slightly, took a sip of milk tea, stared at Xu Qingzhou with bright eyes, and said, "Do you want to drink my cup?" "think." Xu Qingzhou nodded and exchanged milk tea with her. What a tsundere, he clearly wanted to drink his own cup, but he had to ask if he wanted to drink it. Song Yao's eyebrows curved, she took a big sip of milk tea, her eyes sparkling. She found another benefit of being in a relationship, she could taste two flavors of milk tea when she bought one. After returning home, taking a shower, heating up the leftovers from lunch, and finishing their meal, the two of them got busy again, one working on algorithms at the Quantum Research Institute, and the other reviewing their homework. Xu Qingzhou had originally said that it might rain in a few days, but unexpectedly, at 1 ., there was a loud thunder outside the window, and after a while, the heavy rain came as expected. There was a thunderstorm and the two cats were so scared that they hid in Xu Qingzhou's arms. Song Yao came out of the bedroom, still sleepy, probably woken up by the thunder and rain outside the window. "Xu Qingzhou, you just said you would go to bed in half an hour." "I'm going to sleep now." Xu Qingzhou almost finished, turned off the computer, hugged Er Miao, and said, "It's thundering and raining, are you afraid as a girl?" "I'm not afraid." Song Yao saw through this guy's thoughts. If he said he was afraid, he would probably say, "I'll go to your room to accompany you."
However, to Song Yao's surprise, Xu Qingzhou nodded with a relieved expression, which made her begin to doubt whether she was thinking too much. "Then I'm relieved. But you don't know that I've been afraid of thunder since I was a child. I'm timid. How about letting me squeeze into your room?" "." "Look, Er Miao is also afraid. You are the only brave one in our family. It makes sense for you to take us in." "It can, just go away." Song Yao didn't listen to Xu Qingzhou's nonsense. She snorted, took Er Miao away from his arms, turned around, went back to the house, and slammed the door. Xu Qingzhou sighed. Moving into the bed of Song Xiaohua was a long and arduous journey. In the master bedroom, Song Yao sat on the bed, also distressed. Xu Qingzhou wanted to kiss her recently and especially liked to touch her. It is said on the Internet that boys all need to be released. so. Song Yao lowered her head, her round feet moved uneasily, and her cheeks turned red. She patted her chest again and spat in a low voice: "Only a ghost would help him, just hold it to death!" In the blink of an eye, it is a new week, and it has been drizzling since Sunday. library. Xu Qingzhou is comparing the data from the first week of the experiment. Judging from the curve of the first charge and discharge of the nano-silicon 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, sorted the data, and put it into the prepared analysis model. No. 01 Silicon content (%): 50 Electrolyte type: A C-rate: It took Xu Qingzhou four hours to calculate the data and then write down the results. 1. Based on the feedback from the data, the embedded lithium is captured by silicon atoms rather than the passivation film formed on the surface of silicon particles. 2. In addition to lithium dendrites, another important reason for the drastic capacity decay of silicon negative electrode materials is the corrosion of silicon by trace HF produced by the decomposition of LiPF in the existing electrolyte. After writing to the third point, Xu Qingzhou stopped writing. The computer showed that it was already 3:11 in the morning. 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, she would eat with Zhang Qiong and the others after class. It was already lunchtime, so before 12 noon, the cafeteria was already crowded with people. Some people were even taking out the notebooks next to them to look at them while eating, and after reading them, they would take a few bites of rice and then look at them again. As expected, those who can enter Peking University are basically the best at applying for papers. Xu Qingzhou ordered a set meal with two meat dishes and one vegetable dish, thinking about Professor Zhao and his team's experiment. Due to the drastic volume effect, the particle pulverization causes new silicon atoms to continuously consume Li, making it difficult to form a stable surface solid electrolyte film in conventional LiPF electrolyte. After 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 process. In addition, the one-dimensional growth morphology of silicon nanowires can also shorten the diffusion distance of lithium ions, which is beneficial to the rapid conduction of electrons. However, judging from current experiments, the results are not good. Xu Qingzhou was just about to find a seat when he suddenly heard someone calling him. He turned around and saw Xu Zhengyang and Chen Shiqi. Xu Zhengyang: "Fuck, what are you thinking? I shouted for a long time but there was no response." "Something experimental."
"Let's go. What day is it today? First I met Lao Kong, and then I met you." "Old Kong is here too?" "Well, they're eating over there." There were suddenly four people eating and the place became lively. Xu Qingzhou temporarily put aside the matter of lithium-ion batteries and chatted with his roommate whom he hadn't seen for a long time. Xu Qingzhou glanced at Xu Zhengyang and Chen Shiqi, "You two just came out of the library too?" Xu Zhengyang felt hopeless: "Yes, I have a math analysis test on Thursday taught by Professor Gu, and I am so nervous." Tsk tsk, Xu Zhengyang really needs someone to supervise him. Xu Qingzhou couldn't help but smack his lips. Seeing Xu Qingzhou was very happy, Xu Zhengyang looked resentful and protested, "Old Xu, can you have a little sympathy?" Xu Qingzhou was helpless: "There's nothing I can do. It's hard for me to fully understand your pain." "." (End of this chapter)
