"Hey, what does this man do? Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info" Mao Qiming brought the braised pork to the table, looked at Li Xin's swaying back, and pouted disdainfully.

Yang Rui smiled and said, "It's a graduate student from another school, and he wants to take the doctoral exam in our school, thinking I'm going to do something bad to him?"

"This man thinks he's a character. Mao Qiming said in pieces: "I wasn't there just now, otherwise, listening to him talk to you like this, I have to give him a few slaps, let him know the rules, think that when we were in high school, students from other schools had to bow their heads when they came to our school, otherwise be careful not to be disabled...... Ah, the rest of the meal ticket. ”

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

"You take it, and the next time there is a meeting, if I am not there, you will pay the money. "It's been almost a week since school started, Yang Rui usually eats out, and on Friday he invites classmates in the school cafeteria.

Using this method, Yang Rui's reputation quickly improved, although it was inevitable that there would be a lot of evaluation, but in fact, most of them were positive.

On the surface, his manuscript fee is as much as thousands of yuan, but in the canteen of Peking University, it rarely costs 20 yuan to invite someone to eat for a meal, and most of the time it is about 10 yuan.

Wang Yaping or the researchers in the laboratory, if they consciously help, they will be very comfortable to rub it, and the students who are nervous on the weekend will also come to rub it so freely, Yang Rui doesn't care about it.

Mao Qiming is the only student in the dormitory who comes often. He has a very lively temperament, and he entered the student union with the help of Yang Rui, so he deliberately got very close to Yang Rui, and was willing to help Yang Rui deal with some trivial matters in the dormitory from time to time.

Hearing Yang Rui say that he was collecting the money, Mao Qiming happily picked up the money, felt trusted, and said, "I'll go back and make a small book and keep accounts." By the way, are the students still here? They look old, so let's work. ”

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

"If you call me again, you have to teach him some rules. Mao Qiming raised his somewhat thin arm, gestured twice in the air, and said: "Being a man is important to be honest, right, you can't just come over and talk nonsense, how can you harm him and do good things." ”

Yang Rui smiled and said, "It's true that there is some misunderstanding. ”

"So, hey, how did you misunderstand, do you know a professor who can accept PhDs?"

"I don't know, so it's a bit of a misunderstanding, he thinks I told the professor something, but I didn't say it. Yang Rui was halfway through his speech, and he quietly hid it for something to prevent the outside from talking.

"Your temper is just too good, like this, don't let people ride it in the face, the next time this graduate student comes again, you must call us. Mao Qiming said, stretched out his chopsticks, and rushed towards the braised pork.

Li Xin, who left the cafeteria, walked around the campus of Peking University before returning home.

He deliberately went to stimulate Yang Rui.

Li Xin is not afraid that Yang Rui will find "relatives of the Department of Higher Education" for help, it is 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, and several other doctoral supervisors are academic, for Li Xin, there is no difference.

Li Xin changed a professor's doctoral student to take the exam, which basically cost nothing, but Yang Rui wanted to prevent him from taking the doctoral exam of a certain supervisor, according to Li Xin's thoughts, but it was a lot of cost.

Therefore, Li Xin was a little expecting Yang Rui to stop him, he provoked a while, and went to see Professor Tao again, but he didn't find that Professor Tao's attitude had changed, so he was relieved, thinking: Yang Rui would be fine if he gave up.

Yang Rui naturally did not give up.

He just used the means, which were completely different from what Li Xin imagined.

He didn't even spend much time on himself, he just borrowed the resources of Wei Zhenxue and the laboratory.

The time spent by Wei Zhenxue and the resource consumption of the laboratory were far less than the two expected.

"This man is too lazy. Wei Zhenxue, who had redone the experiment, saw Yang Rui again, and commented on Li Xin's experiment with disdain, saying: "It was originally a very simple experiment, he didn't do it well, and he had to guess ......."

"Did you guess right?" this is the main point of Yang Rui's attention.

Scholars are not fools, and simple academic fraud is usually the first researcher who cannot make the desired experimental results to match the topic or conclusion of his paper, so he creates false figures or even false charts.

Sometimes, they are right, other times, they are wrong, and the purpose of the experiment is the same, to test whether the theory is correct or not.

Therefore, whether academic fraud can be detected often becomes a question of probability, and in some cases, some people can guess the experimental results correctly even if they omit the experimental steps, and it is much more difficult to expose this kind of academic fraud.

Wei Zhenxue smiled and said, "Guessing right is guessing right, but his data is impossible." ”

"Why?"

"There is a problem with the basis of his experiment, there should be a collective shift, so if he really does the experiment and does it completely, he will find that there is a problem with the data, and after careful processing, he should be able to find the collective shift, and then, the data can be used. As a result, there was no deviation in his data at all, so it was determined that it was fake. Wei Zhenxue said a little proudly.

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

Especially the collective cheapness that is not rigorous, some data will be quite confusing, saying that 2468 becomes 3579 is a collective shift to the right by 1 position, and the judgment of 2378 is not easy to say, when the data becomes very much and very complex - think about the Olympiad problems that make people want to vomit, you can get a glimpse of the difficulty of the part.

"I'll see. Yang Rui took Wei Zhenxue's experimental records and checked them line by line.

Find someone else to fake, and if you find that you have a problem with your data, it will be embarrassing.

At Yang Rui's request, Wei Zhenxue's experimental records were very complete.

It's a good habit to get a good idea when the lab record is a complete picture of the experiment, and the wrong experiment becomes just as valuable as the correct one. If something goes wrong, you can look up the cause through the experiment log.

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

But when Yang Rui progressed to the rank of scientific research worker, he gradually discovered 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 are from different manufacturers and there is no complete experimental record, and the two experiments are not done in vain.

It can be seen from Wei Zhenxue's experimental records that the deviations in his first experiments were very large, but the deviations were concentrated in a certain area.

Next, Wei Zhenxue did several experiments to determine the deviation value, so as to determine the final curve.

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

"It's a lazy thing. Yang Rui gave a similar evaluation.

To be fair, it is estimated that it took a lot of time for his thesis to be established, and then he ran the funds and other funds, and then determined the goal, the time is tight, the money is tight, and it is possible that he can't achieve the result like mine. Wei Zhenxue entered the boasting mode again in an instant, and said: "Of course, if you want to make a result like mine, you can't do it if you don't have enough level......

"It's true that the pressure of graduate students is great, he spent more than a year to do three papers, an average of one is half a year, if it doesn't go well, or the funding is not in place, it is true that he may not be able to complete the experiment, but this is not a reason for fraud, he has one thesis is enough to graduate, pursue three papers, and then use fraud to complete?" Yang Rui shook his head and said, "He is just staring at the goal of the doctor." ”

"Maybe. ”

"Okay, the paper is published, and then send a letter to his editor-in-chief for them to deal with. Wei Zhenxue published his paper as usual, and the journal that published Li Xin's paper will naturally find a way to solve the problem, usually by retracting the paper and notifying the unit.

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

"There's something else. Wei Zhenxue's smug look did not disappear, and he said: "I found something else by the way." ”

"Something else?"

"Metallic glass, I remade iron-based glass, and the final product I got felt like the soft magnetic properties had improved. ”

"Feelings?"

"I didn't find a similar literature, but comparing the performance of finished products on the market, it should be improved. Wei Zhenxue was a little excited in his words, and it was not the same to make a pure laboratory research in kind.

Yang Rui was also pleasantly surprised, and said: "As long as the performance is better than the finished product on the market, it's good, it's good, this is the first achievement in our laboratory, if you can earn back the cost of the experiment, I will give you a bonus!"

It is a rare joy in the laboratory to make additional surprises for those who engage in research, and there are many laboratory legends born from this.
