Chapter 323

"Well? What does this man do? It's very arrogant. " Mao Qiming brings the braised pork to the table, and looks at Li Xin's swaying back, disdaining his lips.

Yang Rui laughed and said, "I'm a graduate student from a foreign university. I want to be a doctor of our university. Do you think I'm going to do him a bad job?"

"This man, he thought he was a character." Mao Qiming read: "I was not here just now. Otherwise, I had to slap him to let him know the rules when he talked to you like this. When we were in high school, students from other schools had to bow their heads when they came to our school. Otherwise, we should be careful not to be beaten up... Well, the rest of the meal tickets."

Mao Qiming put the braised meat on the table, and returned the extra meal tickets to Yang Rui.

"Keep it. Next time there's a party, if I'm not here, you'll pay for it." It's nearly a week since the beginning of school. Yang Rui usually eats out. On Friday, he invites his classmates in the school canteen. Whoever wants to come, he just pays the bill, no matter what they do.

In this way, Yang Rui's reputation quickly improved. Although he could not avoid the evaluation of big money, in fact, it was mostly positive.

On the surface, his contribution fee is as much as several thousand yuan. In the canteen of Peking University, it rarely costs 20 yuan to invite people to dinner. Most of the time, it's about 10 yuan. It's not outstanding to invite everyone first once a week.

If Wang Yaping or a researcher in the laboratory consciously helps, he will feel free to have a rub. If the students are nervous at the weekend, they will also feel less comfortable to have a rub. Yang Rui doesn't care.

Mao Qiming is the only regular student in the dormitory. He is very flexible, and with the help of Yang Rui, he joined the student union, so he went very close to Yang Rui and was willing to help Yang Rui deal with some trivial matters in the dormitory from time to time.

When Yang Rui said that he was taking the money, Mao Qiming happily put it away. He was trusted and said, "I'll go back and make a small book to keep accounts. By the way, are the students from other schools still here? It looks very old. Let's go to work. "

"It's time to work, educated youth, go to university and graduate school." Yang Rui said casually.

"Call me again, you have to teach him some rules." Mao Qiming raised his thin arm, made two gestures in the air, and said: "honesty is the most important thing in life, isn't it? You can't just come here and talk nonsense. How can you do bad things to him?"

Yang Rui laughs and says, "there are some misunderstandings."

"So, ah, what's the misunderstanding? Do you know a professor who can accept a doctor?"

"I don't know, so it's a misunderstanding. He thought I said something to the professor, but I didn't say it." Yang Rui said half of what he said, and he quietly hid what he said to the outside.

"You have a good temper. If you don't let people ride on your face, next time this graduate student comes back, you must call us." Mao Qiming said, holding out his chopsticks and rushing to the braised meat.

Li Xin, who left the canteen, walked around the campus of Peking University and just returned home.

He went out of his way to stimulate Yang Rui.

Li Xin is not afraid of Yang Rui's seeking help from "relatives of the Department of higher education". It's a big deal to change another professor to test his doctoral students. There is no doctoral student of Professor Li, who is optimistic in advance. The other doctoral tutors are academic. For Li Xin, there is no difference.

There is little cost for Li Xin to change a professor's doctoral student to take the examination. However, Yang Rui wants to prevent him from taking the examination of a tutor's doctoral student. According to Li Xin's idea, it costs a lot.

Instead, Li Xin expected Yang Rui to stop him. He made a provocation and went to see Professor Tao again. He didn't find that Professor Tao's attitude had changed. So he felt at ease and thought: Yang Rui, it's better to give up.

Naturally, Yang Rui did not give up.

He just used different means, which is totally different from what Li Xin imagined.

He didn't even spend much time, but borrowed the resources of Wei zhenxue and the laboratory.

And the time Wei zhenxue spent and the resource consumption of the laboratory were far less than the two people expected.

"This man is too lazy." Wei zhenxue, who has redone the experiment, meets Yang Rui again. He disdains Li Xin's experiment and says: "it was a very simple experiment, but he didn't do it well, so he had to guess..."

"Guess right?" This is Yang Rui's main concern.

Academic fraud is not a fool, simple academic fraud, usually the first researcher can not make the expected experimental results, in order to meet the theme or conclusion of their own paper, so they make false figures or even false charts.

Sometimes they are right, sometimes they are wrong, and so is the purpose of the experiment to test whether the theory is correct.

Therefore, whether academic fraud can be found often becomes a question of probability. Sometimes, even if some people omit the experimental steps, they can guess the experimental results correctly. In the face of this kind of academic fraud, it is much more difficult to expose it.Wei zhenxue said with a smile: "you guessed right, but his data is impossible."

"Why?"

"There is something wrong with the basis of his experiment, so there should be a collective deviation. So if he really does the experiment and does it completely, he will find that there is something wrong with the data. After careful processing, he should be able to find the collective deviation, and then the data can be used. As a result, there was no offset in his data, so it was definitely fake. " Wei zhenxue is a little proud.

It's easy for him to say, but it's not easy to find out such data problems. It takes a lot of calculation and a little luck to find out.

In particular, the lax collective is cheap, and some data will be quite confusing. It is said that 2468 becomes 3579 because the collective has shifted one position to the right, and 2378 is not a good judgment. When the data becomes too much and complex - think about the puzzling Mathematical Olympiad, you can see the difficulty of some parts.

"Let me see." Yang Rui takes Wei zhenxue's experimental records and checks them line by line.

If you find something wrong with your data, you will be embarrassed.

At Yang Rui's request, Wei zhenxue's experimental records are very complete.

This is a good habit. When the experiment record can fully reflect the experiment, the wrong experiment will become as valuable as the correct experiment. If there is a problem, you can find the reason through the experimental records.

When Yang Rui first became a research dog, he paid little attention to this point - the research dog didn't need much brain, and it didn't need to judge the conclusion through the experimental records, it just had to work.

But when Yang Rui progressed to research migrant workers, he gradually found the benefits of experimental records.

In many cases, the similarities and differences between the two experiments may be due to the fact that the two bottles of reagents come from different manufacturers and there is no complete experimental record, so the two experiments can not be done completely in white.

From the experimental records of Wei zhenxue, we can see that the deviations of his first few experiments are very large, but the deviations are concentrated in a certain area.

Next, Wei zhenxue made several experiments to determine the deviation value, thus determining the final curve.

Compared with Li Xin's paper, Wei zhenxue's experiment is more difficult, the difficulty of data processing is also increased several times, and before the calculation, the probability of getting the desired conclusion is also reduced.

"A real slacker." Yang Rui gave a similar evaluation.

"To be fair, it's estimated that he spent a lot of time on the project of his thesis. He spent more money and other funds, and then determined the goal. If the time and money are tight, it's possible that I can't achieve such a result." In a flash, Wei zhenxue went into the mode of boasting again, saying: "of course, if you want to make such a result as me, you can't be good enough..."

"It's true that graduate students are under great pressure. He has spent more than a year doing three papers, with an average of half a year. If he doesn't do well or the funds are not in place, he may not be able to finish the experiment. However, This is not the reason for falsification. One thesis is enough for him to graduate. He pursues three theses and then completes them by means of falsification Yang Rui shook his head and said, "he just went to the doctor's goal."

"Maybe."

"OK, the paper will be published, and then a letter will be sent to the chief editor of his paper for them to deal with." It's not an academic dispute. There's no need to write a fake paper. Wei zhenxue publishes his paper as usual, but the journal that publishes Li Xin's paper will naturally find a way to solve the problem, usually withdrawing the paper and reporting it to the unit.

Li Xin's master's degree will also be in jeopardy.

"There's something else." Wei zhenxue's elation did not go, and said: "I found something else by the way."

"Something else?"

"Metallic glass, I redone the iron-based glass, and the final product feels as if the soft magnetic properties have been improved."

"How do you feel?"

"I didn't find any similar literature, but after comparing the performance of the finished products on the market, it should be improved." There is a little excitement in Wei zhenxue's discourse, and it is still different to make physical and pure laboratory research.

Yang Rui was also surprised and said: "as long as the performance of the finished product is better than that of the product on the market, it's good. This is the first achievement in our laboratory. If we can earn back the experimental expenses, I will give you a bonus!"

It's a rare pleasure for a laboratory that researchers come up with extra surprises, and there are many legends about the laboratory.
