Ao Tianyang wanted to make a reasonable request, asking to leave with Vice Principal Tan with Shen Yiyi, but when the words came to his lips, he found that he did not have a full position to do so, so he hesitated again.

In the end, he could only watch Shen Yiyi and Tan Zhong walk into the gate of Tsinghua Garden before the rest of them.

Shen Yiyi and Vice President Tan naturally didn't think about it so much. Walking beside Vice Principal Tan, she jokingly asked Vice Principal Tan, "Teacher Tan, where are you taking me?" You can't be trying to sell me secretly, are you? Then I'm going to have to think about whether I should walk away quickly. ”

Tan Zhong finally touched this girl who had managed to get him to his school a few months ago, and his mood today was very different from before. Therefore, Vice President Tan, who has always been serious, responded happily in the face of Shen Yiyi's jokes today: "If you don't come to my research group early, our project has been delayed for so long, and the losses caused are up to you to make up for it." You can't make up for my losses even if you sell it. ”

Shen Yiyi knew that Tan Zhong was purely a joke. He was at his school at the time, but he was tempted by the special admission slots, but he didn't have time to talk to her about his own subject. Therefore, Shen Yi still does not know what research topic Vice President Tan is engaged in.

An old man and a young man pushed their bicycles like this, talking and laughing and walking towards the laboratory building of the original college of Vice President Tan Zhong.

In addition to the fact that most of the school leaders are promoted from the line of ideological and political teachers, most of the formal administrative leaders are promoted from the front line of actual teaching and scientific research. So no matter how in-depth Tan Zhong himself is actually doing research now, he was still doing practical work at least not long ago. Of course, the authority in Mr. Tan's hands is not the same as it was a few months ago. At least now, if he comes to lure Shen Yiyi with the two President Weng of Jiaotong University with generous conditions, Vice President Tan will no longer lament that his capital is not enough. Of course, Shen Yiyi's own heart is firm. It's not so easy to be lured in.

Vice President Tan still has a lot of affection for the building where he has worked for so long, and as he walked, he introduced to Shen Yiyi the faculty and scientific research level of their own college, and naturally the research situation of the topics they are currently engaged in.

Shen Yiyi, in fact, where did he not know the brilliant research of Lu Dao Tsinghua during this time? In her previous life, in order to write some scientific papers, she searched for the field she studied, and she still had some impressions of domestic scientific research topics in the 1990s. The research topics of Tsinghua University and the Chinese Academy of Sciences, which are the vane of domestic scientific research, certainly represent the hot spots of scientific research in this era. However, of course, she can't reveal the essence of being a time-traveler. It's just that he carefully confirms the difference between his memory and reality.

While introducing Vice President Tan, he did not forget to tempt Shen Yiyi.

"One by one, classmates, you see, there are not many devices in the country for laser measurement of liquids. Our school has this condition, and we have specially imported such a set from Japan. Vice Principal Tan showed the equipment to Shen Yiyi one by one, "You have to know that as soon as this thing comes out, you can throw away whatever you want." The accuracy of the results of this test is high. ”

Shen Yi nodded. How could she not know the way. By the time she was in her on-the-job degree, laser measurement of the flow field was already a trend. It is true that the traditional Bitograph tachymeter has inherent limitations in measuring the direction of the flow field. Because Bitu actually uses a needle tube with a round hole to extend into the fluid, it will inevitably affect the local flow field, and the accuracy of the reading will be reduced in terms of accuracy and logic. And there is hope for solving these problems because of the laser flow field measurement technology.

"How's it going, Yiyi-san? If you come to Tsinghua. This instrument allows you to measure the flow rate more accurately, so that the accuracy of the verification test will be fully improved. Moreover, even the flow field can be clearly displayed. This set of instruments is still not available in other parts of China. ”

Shen Yiyi listened to Tan Zhong's words and felt a little funny in his heart. The meaning of Tan Zhong's words was clear to Shen Yiyi. It's just that Tan Zhong doesn't have to show his thoughts so obviously. Even if he didn't tempt Shen Yiyi, Shen Yiyi would still fill in the college entrance examination two years later. This is what she has already made up her mind. It's just that of course, this idea can't let Tan Zhongzhi Dao now.

Therefore, Shen Yiyi deliberately found a reason to hit Tan Zhong: "Of course, this laser testing technique is advanced, and it can also achieve an accuracy that has never been achieved by previous testing techniques." But Mr. Tan, you didn't find out. Is it because of the introduction of laser measurement technology that a certain measurement limitation has a greater impact on a parameter? ”

Tan Zhong had always wanted to use this kind of technique that had only recently been developed in the world to satisfy Shen Yiyi. He knew how much people who liked engineering and art had a thirst for all kinds of epoch-making research tools. It's just that the original intention was to take something out casually to lure Shen Yiyi into the bait, but he didn't expect that Shen Yiyi actually seemed to have something to say about such a revolutionary measurement method. He asked curiously, "So you also have research on such a new measurement method?" Tell me about it. What are the limitations of such measurement techniques? ”

Shen Yiyi pointed to the fluid pipeline that was deliberately made of transparent materials in order to transmit light, and said to Vice Principal Tan Zhong: "You see, in order for the laser to pass through, this fluid pipeline must be made transparent. In this way, some of the metal pipes used in traditional pipes are useless, and there is no way to measure them in this way. But as you know, one of our main research tasks in fluid mechanics is the effect of viscosity on flow. Now this kind of tubing can only be made of this transparent material. Therefore, there is no way to obtain the relationship between the viscosity of the fluid and the basic properties of the fluid. ”

Tan Zhong listened to what Shen Yiyi said, and his eyes lit up when he heard it. He believes that it is impossible for Shen Yiyi to see this kind of test equipment to a large extent. Because this kind of equipment is not only the latest model that is being studied abroad, but also because the price of this kind of equipment is quite expensive. It was precisely because of these two factors that it was unlikely that Shen Yiyi had seen these devices outside of himself, let alone understood the limitations of these devices.

And Shen Yiyi just glanced at it. I immediately discovered the biggest problem with this latest test technique, which shows that Shen Yiyi's high level of understanding is really what they dream of as teachers!

Every teacher wants their students to be not only solid and knowledgeable, but also flexible. Such students may be good helpers for teachers on the road of scientific research. And Shen Yiyi's identity as the discoverer of the formulas that have now become the favorite in the domestic academic circles has confirmed her solid foundation and rich knowledge in this area. Now, she can see at a glance the shortcomings of this new measurement method. How could such a student not let him, a teacher, want to be recruited under his name?

Shen Yiyi further gave his own analysis: "And Mr. Tan, you see, whether it is Bi Zhi or this method, because of the nature of the data of the measured speed, this determines that the reading is always an indirect data, not direct data. The accuracy of such data will be greatly reduced. ”

Indeed, while Bishop knows the flow rate of a fluid by means of differential pressure readings; However, the laser measurement method is still the method of dividing the distance by the time. Due to the fact that the equipment of this era is not powerful enough, it is impossible to clearly outline the trajectory of each fluid micromass, and can only be analyzed after the fact by constantly exposing and taking pictures. Shen Yiyi then said to Tan Zhong: "So, Mr. Tan, you spent a lot of money to buy this machine. However, I believe that if you really invest in the research of the subject, after using it, the subsequent cost will only increase further, not decrease. Do you think that with our country's current investment in scientific research, how many more topics can you use this instrument in? A device that can't be used, do you think it's a happy thing or a painful thing to have it? ”

Tan Zhong had to admit that Shen Yiyi was quite reasonable. In order to pay off the development debt owed by the current national economy, it has to reduce its spending in many aspects. Whether it's education, health care or hygiene, they all face the need to lay off workers. Under such circumstances, even in Tsinghua University, every year, he has to devote a part of the limited education funds to do this test, and he thinks that it is quite difficult!

Shen Yiyi, a little girl, can come up with such a good excuse so that she can refute it, and the flexibility of this little girl's mind can be seen. With such a student, he Tan Zhong wants to recruit into the school even more.

In such an office that Tan Zhong wanted to bring Shen Yiyi to, they were all disciples recruited when he was still in the academy. Tan Zhong opened the door of his office and was very satisfied to see that these disciples were still seriously studying the topics they had assigned to them.

The students who were in the room frowned and raised their heads in the room, and only let go of their brows when they saw their teachers. A few of them were obviously in charge and took the initiative to greet Teacher Tan: "Teacher Tan, are you here?!" ”

Tan Zhong greeted them very amiably, and took the initiative to introduce Shen Yiyi to them. (To be continued......)
