Chapter 368 The conversation turned sour Saturday. At the intersection of Wusi Road, Xu Qingzhou looked at the girl who was glaring at him and said, "You really don't want me to go?" "Xu Qingzhou, the meaning of life is not about love and affection. Can you have some pursuits?" Song Yao raised her eyebrows. “I just went there to study.” "Are you going there to study?" Song Yao exposed him. This guy knew everything and just went there to find excitement. "Isn't it?" "If you dare come here, your night is over." After making the threat, Song Yao turned around and strode towards the seminary. "Ugh." Xu Qingzhou sighed. Being disliked by his girlfriend, he could only find a separate classroom to study. Actually, he could also study at home, but staying at home all day would make him look like a useless stay-at-home person like Er Miao.
The model that Song Yao's research team needed could be completed by one person within three weeks. Time is not tight, so Xu Qingzhou plans to start working on the second option in the morning, visit Academician Chu Jiangfeng in the afternoon, and then make the model later. 2 pm. "Did you go to the School of Economics to help?" Chu Jiangfeng paused while drinking tea and was stunned. "Well, Professor Li Daiyue's research group needs someone to handle some calculation problems." "You kid, people say that I'm a very eclectic person, but now it seems that you are much more wild than me." Chu Jiangfeng said with a smile, but didn't say anything. He respected his students' choice, and the one he went to was the research group of the boy's girlfriend. "However, from my personal experience, trying different fields is a good thing, which is essential to broaden your horizons and enhance your abilities, but you must also be careful about making choices and not spreading your energy too thin." "Thank you for the reminder, Professor." Xu Qingzhou nodded seriously. If he didn't have the extra decades of experience from his previous life, he would not have dared to be so careless and try everything. Some people may win at the starting line, but he is different, because he has already run to the finish line. Chu Jiangfeng shook his head and said with a smile: "It's not a reminder. You are much better than us old guys." "It really doesn't work. Here, the integration by parts shows that the mapping ξ decays rapidly outside the rectangle. There is no other way, unless you can infinitely increase the calculation, but this is obviously impossible to achieve. At least, it is impossible with the current computing power." "Yes, so I want to try the second method. First, assume that Q and X satisfy the angular separation condition in this formula and convert the target into an estimate." Xu Qingzhou spent the entire afternoon discussing math problems with Chu Jiangfeng. Although Chu Jiangfeng is not engaged in local smoothness research, he has a sharp eye and can often see the problem at a glance, which can give Xu Qingzhou a lot of inspiration. It's time to leave. "Qingzhou, you are still young and have many opportunities. If you find that this path is not working, then slow down, adjust your strategy and methods, set a clear goal and plan, and come back to check after you have learned something." "I've remembered that." Xu Qingzhou nodded slightly. What Chu Jiangfeng meant was that if the study of local smoothness was difficult, he could try other methods instead of relying on one thing. "Okay, I'm old and a bit nagging, so just go ahead."
"Don't be long-winded. I like to listen." Xu Qingzhou chuckled. There are not many opportunities to hear an academician give instructions and impart life experiences to one. Chu Jiangfeng waved his hand. After coming out of the office, he glanced at the message and did not return to the classroom. He went straight home to change his equipment and went to the playground with Song Yao to sweat. Xu Qingzhou was busy for two consecutive weeks, and the research on the autoregressive integrated moving average model and local smoothness was carried out simultaneously. Song Yao was also very busy and went to the Magic City with Li Daiyue. It wasn't until December 12 that the two decided to take a vacation. 12 points in the early hours. The dusk was thick, and the snow that had just stopped in the morning began to fall again. There was a layer of ice crystals on the glass. Song Yao was wrapped in pajamas, drawing on the glass with her fingers. At the table, Xu Qingzhou was calculating with his head down. The autoregressive integrated moving average model is progressing smoothly. The method of converting the target into an estimate in the study of local smoothness does not work either. Xu Qingzhou is ready to fight to the death. After a while, Song Yao turned around and showed her masterpiece, two little figures, on the glass, and asked Xu Qingzhou for his opinion: "How is the painting?" Xu Qingzhou glanced at the two little figures drawn with the help of heat. They were so ugly. "Don't ask me such difficult questions. Also, other people's drawings of couples are all of them cuddling together and being sweet and loving. Why did you draw a picture of someone beating me up?" "Don't you like it?" "." Song Yao narrowed her eyes, walked over, and combed Xu Qingzhou's hair from behind, "My skill points may have gone into beauty and intelligence." "No, I think it's more about the use of force." Xu Qingzhou found that School Beauty Song did not have a clear understanding of herself. Song Yao pouted and rubbed Xu Qingzhou's face a few times, "I'm going to bed, you um, go to bed at 12:10, do you hear me?" "Ah." Seeing Xu Qingzhou agreed, Song Yao yawned and walked to the bedroom. Xu Qingzhou shook his head and focused his attention on the equation in front of him. Here, φ(x, t) can be used to represent the inverse mapping in (). In the new coordinate system, the phase function is transformed into other functions, but. Xu Qingzhou spent a long time calculating. 10 minute later. "Whoo~" Xu Qingzhou exhaled slowly, but it still didn't work. He stared at the manuscript for a long time, and then an idea came to his mind. If both sides calculated the sum of all μ. Maybe there is a way.
Soon, there was a rustling sound of writing in the living room. "Xu Qingzhou, go to bed." Xu Qingzhou was brought back to reality by the sound coming from the bedroom. "Just a moment." Xu Qingzhou replied without even looking up, formulas appearing from his pen one after another. After a moment, he suddenly looked up again, "Damn, it still doesn't work?" I feel a little numb. He was about to pick up his pen to continue his work when a faint voice suddenly rang in his ears: "Go to sleep, or let me beat you up before you go to sleep." Xu Qingzhou turned around and saw Song Yao with a sour look on his face. He glanced at the time and saw that it was already half past twelve. He immediately laughed awkwardly: "Oh, it's so late, go to bed." He ran back to the bedroom and hid under the quilt. It's warm, fragrant, refreshing, and even makes you less tired. It’s great to have a girlfriend who keeps you warm in bed. Xu Qingzhou felt emotional. Song Yao stood at the door, looking at her boyfriend who had obediently crawled into bed, and snorted softly. She could see that this guy was determined to work hard on the math problems. Get stuck in a rut. Last time you said you could move forward and backward freely, but you seem to be stuck again. It doesn’t matter if you can’t solve the math problems. You can study them tomorrow. Your body is your own. Don’t you know that staying up late will damage your kidneys and your body? "Jiahui asked if we wanted to spend New Year's Eve together this year." Lying on the bed, Xu Qingzhou relaxed all of a sudden, "Let's go together, it will be more fun with more people." "Okay, I told her that the new year should start with a bang." Seeing that Xu Qingzhou seemed to still have his eyes open, staring at the ceiling stupidly, Song Yao poked his face and asked, "Are you still thinking about math problems?" "Well, let's consider whether to start the third plan as soon as possible." Song Yao said with disdain: "Tsk, last time someone said he could move forward and backward freely, but he still got stuck." "Yes, I need to be as relaxed as you. Why was our conversation so weird today?" "Shut up, you!" "." (End of this chapter)
