Chapter 150: What's the matter with feeling greatly benefited? At noon at Peking University, the warm sunshine spreads on the earth. Two young people are walking slowly on the road with hot milk tea in their hands. Xu Qingzhou was really curious about the girls' train of thought. For example, when she was eating just now, this girl didn’t even dare to eat one more bite of rice, and she kept shouting that she wanted to lose weight. As a result, after just walking around outside, I was attracted by the second cup of half-price milk tea. After walking for a while, the two sat by the Weiming Lake to bask in the sun. During this period, many people from other schools come to Kyoto University to play. There are girls checking in by the Weiming Lake. It's winter, and they are wearing very little clothes, white boots and stockings. It looks a bit like summer, so much so that Xu Qingzhou is beginning to wonder if they are in completely different seasons. "Hello~" Seeing Xu Qingzhou always staring at other girls, Song Yao became unhappy.
What are you looking at? It's just because it's winter and she's wearing thicker clothes. She took another look and compared herself to that girl. Well, compared to her, she was wrapped up like a dumpling. Xu Qingzhou retracted his gaze, "It's normal to take a look at beautiful things." "Hehe." Song Yao expressed contempt, and couldn't help but carefully look at the girl in the distance. Her eyes were a little envious, and at the same time a little curious. Isn't she cold wearing so little? Seeing that Song Yao had been staring at the girl, Xu Qingzhou asked expectantly: "Do you want to wear it too?" If Song Yao wore the leg-revealing artifact, she would probably have a different kind of beauty. "Pierce your head!" Song Yao stared. She finally realized that this guy just liked legs. After complaining, she sighed in distress. It was too cold here in Kyoto. As a person who had lived in the south all year round, she was shivering from the cold every day, not to mention wearing those figure-hugging clothes. Xu Qingzhou said nothing and shook his head with some regret. However, as Dean Tao said, since the award ceremony, the number of media in the school has dropped sharply, and Xu Qingzhou's life has finally returned to normal. He was not idle. Besides reading, he was running around the laboratory to debug equipment and train the assistant. He had to improve Ren Xiaoling's experiments and skills as soon as possible so that he could be lazy in the future. In the morning, at the experimental center, Zhong Xiaodong decided to take a look at the laboratory. After all, Director Ji had repeatedly told him to take good care of Xu Qingzhou, and if he could help in any way he could, he would. However, as soon as I approached the laboratory, I heard intermittent voices. In the lounge next to the laboratory. Xu Qingzhou was holding a notebook, on which Ren Xiaoling had written down the questions that she didn't understand. "Here ω is the center frequency of the signal light." "Oh, okay, then why can't nonlinear media use anisotropic crystals?" "If anisotropic crystals are used as nonlinear media, a spatial walk-off effect will occur due to the birefringence effect, affecting the efficiency of parametric down-conversion and thus having an adverse effect on the generation of compression." Ren Xiaoling nodded quickly and wrote quickly with the pen in her hand, admiring Xu Qingzhou deeply in her heart.
Zhong Xiaodong had a strange expression on his face. If he remembered correctly, Ren Xiaoling was a senior student, right? Although we know that Xu Qingzhou is a genius, seeing such a scene still makes people feel strange. But why would he, a doctor, feel that he has benefited a lot? No, no, no, it’s an illusion, it must be an illusion! "Teacher Zhong, is there anything I can do for you?" Xu Qingzhou noticed Zhong Xiaodong outside the door. Zhong Xiaodong came back to his senses, smiled and shook his head, "It's okay, just look around, you guys are busy, you can call me if you have anything." "Thank you, Mr. Zhong." Xu Qingzhou thanked him, knowing that Zhong Xiaodong was probably worried about him and Ren Xiaoling. The morning was for theoretical tutorials, and the afternoon was for practical exercises. Xu Qingzhou first explained to Ren Xiaoling the usage process of the mode-locked femtosecond laser. Ren Xiaoling wrote down the key points Xu Qingzhou said in a small notebook from time to time. After saying everything, Xu Qingzhou pointed at the equipment and said, "Operate it first." "Ok." Ren Xiaoling had a serious expression on her face. She put on her goggles and prepared to turn on the controller switch on the control panel. Xu Qingzhou shook his head helplessly and stopped her. "When using a mode-locked femtosecond laser, in addition to checking the cooling water circulation system, you must also preheat the pump source to avoid thermal effects as much as possible." "Oh, okay, okay." Ren Xiaoling suddenly felt a little ashamed. When she went back, she specifically searched for it and found that this device alone cost more than two million. "Why are you so nervous?" Xu Qingzhou couldn't help but ask. Ren Xiaoling said embarrassedly: "If I accidentally break the machine..." "Then you're done. This machine is estimated to cost one or two million." Xu Qingzhou shook his head and sighed, "Then you can work to pay off your debts for the next ten years." "Ah?" Ren Xiaoling was frightened. Xu Qingzhou rolled his eyes and said unhappily, "This equipment is not that valuable. It won't break just because you touched it a few times." After that, Ren Xiaoling was much more focused and basically no major problems occurred. "If the automatic mold locking fails, you will need to manually adjust the components in the cavity, such as the lens." As he said this, Xu Qingzhou opened the lid with a "click". This violent action scared Ren Xiaoling who was standing next to her. This system is still quite different from what he used before, and he still needs to work harder to achieve the same experimental results as before. After all, he doesn't have the previous experimental data, so he has to start all over again. Of course, the advantage is that every experimental step is engraved in your mind, so you won’t go astray during the experiment. After Ren Xiaoling repeated it twice, Xu Qingzhou nodded and said, "I will now show you how to use the optical parametric oscillator." In the next few days, Xu Qingzhou basically spent all his time in the quantum optics laboratory, which was full of high-tech equipment, and it was not easy to debug to the optimal parameters. 206 Dormitory. The sound of water in the bathroom stopped. The girl came out of the bathroom rubbing her hair, her chest bulging, her white and well-proportioned calves exposed under her nightgown, with water droplets still hanging on them that had not been wiped off.
"Have I really gained weight?" Song Yao couldn't help but look at her legs. They were long and white. That guy must like them. They seemed no different from those in the summer. Thinking about this, she stood in front of the full-length mirror again and touched her waist. There was no extra fat. Humph, that bastard Xu Qingzhou is talking nonsense, there is no change at all! No, it seems there are changes. Song Yao exhaled slowly and placed her hands on her chest. Pinch. Seems a little bigger? um, yes. Future prospects Humming a song, Song Yao sat back at the desk and continued reading. About 10 minutes later, she picked up her phone and called Xu Qingzhou. beep. No one answered the phone. Song Yao glanced at the time. It was already 11: in the evening. Is this guy still busy? (End of this chapter)
