Chapter 322: Schoolgirl Song's idol image is gone 8: in the morning. The sun has come out, and the sunlight penetrates the glass and falls onto the windowsill. In the bedroom, Xu Qingzhou and his partner were both lying in bed. They had been running around outside for seven or eight days and had experienced a thrilling battle last night. They were already very tired, and now they were even more tired. Song Yao was taking a nap. Xu Qingzhou didn't feel sleepy, but he didn't want to get up either. He ran out of food and ammunition last night and now he just wanted to lie down and rest. In the morning, School Beauty Song was particularly charming when she curled up in bed. Her fair cheeks were rosy and she would occasionally talk in her sleep. Especially after the two of them were honest with each other, she completely let go and often hummed and moved in his arms when she fell asleep. Looking at the girl in his arms, Xu Qingzhou couldn't help but realize that it was the first time they met. At that time, he was still in a trance after his rebirth. School Beauty Song and her little sister Ding Jiahui passed by and glanced at him coldly. Then there was borrowing meal cards from the cafeteria and the chance encounter in the library. The memories of Song Yao emerged from my mind bit by bit. His life also underwent earth-shaking changes. According to his original plan, he closed his heart and locked away his love, concentrated on research, and resumed his path to becoming an emperor. As a result, I became addicted to the land of tenderness. Xu Qingzhou smiled, got out of bed quietly, and prepared to buy breakfast, but the sound of getting dressed still woke Song Yao up. Seeing that School Beauty Song had woken up, this fellow reached his dog paw into the quilt and pinched it, "Do you want to sleep for a while or get up?"
Song Yao had become immune to Xu Qingzhou's behavior. She lay on the bed with sleepy eyes and was dazed for a while before she came to her senses. She pulled the man who took advantage of her, pressed him on the bed, and puffed on him a few times. Xu Qingzhou accepted his fate and didn't even struggle. After being ravaged by Song Xiaohua enough, he sat up and said, "Kiss me right after I wake up." "You stink." Song Yao snorted and climbed out of the bed. The delicate skin on her chest was a little red, revealing two slender and white thighs. Xu Qingzhou shook his head, helped Song Yao take out clothes from the closet and handed them to her, thinking that the school beauty Song was becoming less and less burdened by her idol image. In the past, when I just moved out, I saw her every morning. Although she was still bare-faced, her eyes were sparkling, and she was cold and elegant, still looking like a goddess. Look at now. At 9 o'clock in the morning, the two washed up, got dressed, poured some cat food into Ermao's automatic feeder, and went out for breakfast. 今年2月9日过年，他们买了2月5日，也就是腊月27的机票。 The last time Ms. Wang called, she also reminded Xu Qingzhou and the others to go back early, but there was nothing they could do. Song Yao had to follow Li Daiyue's project, and he also wanted to read some books at school. However, in Xu Qingzhou's opinion, it is better to go back later. The waiting period for Ms. Wang's visual fatigue is only three days. The first few days were so cordial, with all kinds of delicious food every day, and then all kinds of disgust. After they finished their breakfast, they headed towards the school. At 10 o'clock in the morning, the sun finally fell on us, making us feel a little warm. Kyoto University has already gone on holiday, and there are much fewer people on campus than usual. Xu Qingzhou and Song Yao both went to the library. Professor Li Daiyue went to Guangdong Province for a meeting and would not be back until tomorrow, but the task had already been assigned to Song Yao. library. The two found an empty seat on the third floor. Xu Qingzhou plans to finish reading "Introduction to Fourier Analysis in Euclidean Space" in two days. After cramming for almost a month, he determined his research direction for the next period of time - the local smoothness conjecture of the Fourier integral operator. This is an important direction in studying the properties of operators in harmonic analysis. The Fourier integral operator, also called the Fourier integral operator, is an important tool in the theory of partial differential operators. It is used to describe and solve partial differential equations, especially wave equations and hyperbolic equations. Furthermore, it can reveal the frequency content and phase information of a function by expressing it as an integral of a series of sine and cosine functions.
This can be related to physics. Quantum mechanics describes the movement and interaction of microscopic particles, in which the wave function is a key concept. The Fourier integral operator can convert a wave function from one representation to another, such as changing the spatial representation to the momentum representation, thereby reflecting the momentum distribution and frequency components of the particle. Of course, this is only one aspect of the Fourier integral operator. In addition to physics, in the language of mathematics, it is also an important tool for solving partial differential equations. By utilizing its properties, the form of the equation can be simplified, making it easier to find solutions. Simply put, it can be used in both mathematics and physics. Xu Qingzhou quickly got into the state. On the opposite side, Song Yao had also turned on the computer and started checking the information sent by Li Daiyue. Time flies by. At noon, the two of them were waiting for Zhang Qiong at the library entrance again. At the end of January, some of the people who had stayed in school to study left, and Zhang Qiong was the only one left in the dormitory. After staying alone for a few days, she heard that Xu Qingzhou and Song Yao had returned, so she sent a message to ask them out for dinner. Farm restaurant. "Well, we ended up going to Dongfeng Space City and watched the satellite launch on the morning of the 27th. We just got back last night." Song Yao calmly and briefly recounted last week's journey. After listening to Song Yao's description of the places she had been to during this period, Zhang Qiong looked longing, "I envy you so much. I wonder when I can be like you." Xu Qingzhou asked curiously, "After a year and a half, you don't have any ideas?" Even if Zhang Qiong is not the campus belle or the department belle, she is already pretty good-looking. Her personality is somewhat similar to Ding Jiahui. She is not as immature as Ding Jiahui, but also fun and carefree. Logically speaking, there are many people chasing after her. Zhang Qiong shook her head and sighed bitterly, "I'm not like you two. I can maintain my grades while in a relationship." The competitive pressure is too great, and everyone is so eager to study. She wishes she could spend all 24 hours reading and studying. She has no time for a relationship. Xu Qingzhou subconsciously touched his waist and did not refute. He thought that falling in love would indeed distract his attention and hurt his waist. His waist was a little numb when he got up in the morning. At the side, Song Yao happened to see her boyfriend holding his waist, his hand that was slurping noodles paused, and a blush crept up to his ears. Zhang Qiong sat opposite Song Yao and quickly noticed her abnormality: "Xiaoyao, what's wrong with you?" "It's a little hot." Song Yao shook her head and transferred the fried eggs in the bowl to Xu Qingzhou's bowl. Xu Qingzhou: "I have it." Song Yao nodded: "Well, eat another one." "." After a moment of silence, Xu Qingzhou understood a little bit, and with a sullen face, he took the fried egg back and said, "I don't need another one." Zhang Qiong: “?”
What are these two people doing? It’s just an egg, is there any need to do this? She didn't know that this was not an egg, but a man's dignity! Two days passed in a flash, and on the third night after returning, Xu Qingzhou, who was devoted to scientific research, was dragged by the school beauty Song to the playground to exercise. Xu Qingzhou didn't struggle much. Running can cultivate one's sentiments, strengthen the kidneys and body, so there is nothing wrong with it. Now, under the supervision of School Beauty Song, running 5 kilometers is a piece of cake for him. Overall, I am definitely physically countless times stronger than in my previous life. On February 2, Xu Qingzhou went to the School of Mathematics to meet Academician Chu Jiangfeng. It was their last meeting before the New Year, and he just happened to ask him about a few problems he had encountered. Academician Chu Jiangfeng has a solid foundation, and his experience and knowledge in harmonic analysis far exceed Xu Qingzhou. Basically, once Xu Qingzhou says something, Chu Jiangfeng can find the key points and explain it in a simple and easy-to-understand way. The last question is about the convergence of Fourier series in a wider space of functions. Academician Chu thought for 10 minutes and said slowly: "Here, let's assume that this integral converges absolutely, that is, ∫x0x0+T|f(x)|dx Fourier series is a basic tool in mathematical analysis. The study of its convergence properties is crucial to understanding the frequency characteristics and periodicity of functions. In addition to studying the convergence of Fourier series in classical function spaces such as L2 space and Lp space, it can also be explored in a wider range of function spaces, such as Banach space and Hilbert space. Xu Qingzhou nodded, looked at the formula and thought for a moment, then said, "Perhaps we can try to multiply f(x) by an exponential function, and then integrate one of the periods of f." "Well, this is a good idea, you can try it." Academician Chu nodded appreciatively. He was quite satisfied with this student who could understand any problem at once. At this point, Xu Qingzhou had finished asking questions, and Academician Chu smiled and asked, "The Polignac theorem has come to an end, and the tour is over. Have you decided on the direction of your research?" "The local smoothness conjecture of the Fourier integral operator." Xu Qingzhou replied. Yang Yongze was originally calculating with his head down, then he looked up and said in a deep voice: "Junior brother, this topic is not easy." Academician Chu nodded: "It is indeed very challenging and a hot topic of research. Many research groups around the world are studying the local smoothness conjecture. You are under great competitive pressure." "As for the latest research, Professor Doreen Lewis of Cambridge has improved the results of Mockenhaupt-Seeger-Sogge local smoothness by using tools such as bilinear methods and square function inequalities. She also analyzed the difficulties and possible ways to solve the conjecture. But I heard that the results are not very ideal." Academician Chu paused, then asked with a smile, "Have you thought it through?" What he actually wanted to tell Xu Qingzhou was that even mathematicians who had been engaged in research in this area for many years had not produced any results, so Xu Qingzhou had to be mentally prepared. Xu Qingzhou nodded and said, "I'm just trying it out. After all, this is my first time doing research in this area." Seeing that Xu Qingzhou was very sure, Academician Chu nodded slightly. Although he felt a little regretful, he supported the general direction. After all, he was involved in many fields. It's a good thing that young people are enterprising. After all, this kid is still young. He doesn't have to be like these old guys who want to try new fields but are powerless. After leaving Academician Chu's place, Xu Qingzhou went straight back to the library. In Chengdu, at 6 ., the sky was getting dark and the street lights were already on. The leaves of the sycamore trees on both sides of the road had long since fallen off, leaving only bare trunks. The 27th day of the twelfth lunar month happened to be the evening rush hour on Friday. The roads were busy with cars and people, much more lively than other times. Xu Qingzhou had just gotten off a taxi and was pushing his suitcase towards Wutong Community. There are more things to do at the end of the year. Mr. Xu and Ms. Wang are busy with work, Mr. Song is on a business trip, and Zhang Junli is also dealing with work and has no time to pick them up, so he and Song Yao took a taxi back by themselves. As the timing was not right, the two families simply moved the dinner to Saturday night.
Hey~ Before he even reached the gate of the community, his cell phone rang with a message alert. Song Yao: "Are you home?" Xu Qingzhou: "At the entrance of the community." Song Yao: "Say hello to my uncle and aunt for me." Xu Qingzhou replied "OK" and then pushed his suitcase towards the community. The person on duty at the door was an acquaintance. Uncle Zhang was wearing a military green coat, holding a thermos cup in his hand, and greeted with a smile: "Xiao Xu?" "Yes, Uncle Zhang, aren't you off work yet?" "Hey, we'll be off work in half an hour. You're a celebrity now, on TV every day. Did you just return to Chengdu today?" "Yeah, right, I just arrived today." Xu Qingzhou was embarrassed. How could he be on TV every day? It should be Weibo. However, in the eyes of Uncle Zhang and others, being on Weibo hot searches and being on TV should be similar. "I just said that I saw your parents carrying a lot of food home. Okay, go back quickly. The meal should be ready." "Okay~" At this time of day, the elderly men and women that Xu Qingzhou was familiar with had not gone out for a walk yet. Most of the people in the community were office workers who had just got off work after a busy day. However, Xu Qingzhou did not encounter any scene of being watched. After walking for a few minutes, a familiar old building appeared in front of us. Standing here, you can still smell the faint aroma of food. Go home. Looking at the building, Xu Qingzhou felt a sense of emotion in his heart. No matter how he was doing outside, every time he came back, he always had a sense of peace. "You're standing there like a door god. Come in now!" Just as Xu Qingzhou's emotions were brewing, Ms. Wang's voice suddenly came from the first-floor window. Xu Qingzhou had no choice but to carry his suitcase up the stairs. Now his suitcase has successfully become as heavy as Song Yao's. He doesn't know how Song Yao stuffed so many clothes in. In the past, for a vacation of less than ten days, he would probably just bring some documents and two sets of clothes and come back. As soon as she arrived at the door, it was already opened. Ms. Wang took the suitcase and said, "You didn't even know to come in when you got here. You're standing outside like a silly kid." Although she was being scolded, Ms. Wang couldn't suppress her smile and looked very happy. “I just arrived.” The familiar old building, the familiar smell of food, the familiar nagging. When Xu Qingzhou entered the room, Old Xu was bringing the stewed spare ribs to the table. "dad." Xu Shouyun nodded, with a smile on his face, and said, "Wash your hands and eat."
"it is good." Xu Qingzhou smiled and followed Ms. Wang back to the bedroom. The layout of the bedroom has basically not changed. There are a few bags of rice and barrels of oil piled in the corner. They should be distributed by the unit. If they can't be finished, they are piled in his room. It was normal for the bedroom to be used as a storage room, but what made Xu Qingzhou a little uncomfortable was that his bed sheets were replaced with bright red sheets! "Where are my old sheets?" "It's thrown away. I've used it for several years. It's better to replace it. It's black and shiny. This set looks so festive." Ms. Wang patted the bed sheet. “It’s quite festive.” Xu Qingzhou did not refute. He was thinking about finding time to buy a set of lighter colors. This bright red peony was a bit hard to handle. After putting down the luggage, Xu Qingzhou came out, washed his hands, and helped serve the rice. Ms. Wang was very concerned about her "future daughter-in-law" and asked, "Has Xiaoyao arrived home?" "Well, we're here. I guess we've already had our meal." Xu Qingzhou said. Ms. Wang nodded. "That's good. Let her have a good rest. She must be tired after traveling for seven or eight hours straight." Xu Qingzhou sat down and reminded: "Mom, my son just came back, shouldn't you pay attention to his condition first?" "you?" Wang Xiaping looked at Xu Qingzhou and said, "You are a boy, tall and strong, what do you need to worry about?" "." There is no love in the world anymore.
