"Hey, what does this man do? 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 researcher in the real yàn room, 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 Shi Yàn's room.

And the time spent by Wei Zhenxue and the resource consumption of the real room were far less than the two of them expected.

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

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

People who commit academic fraud are not fools, and simple academic fraud is usually the first researcher who cannot make the desired real results in line with the topic or conclusion of his paper, so he creates false figures or even false charts.

Sometimes, they are right, and other times, they are wrong, and the same is true of the purpose of the truth, 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 real result correctly even if they omit the real process, and it is much more difficult to expose it in the face of this kind of academic fraud.

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

"Why?"

"There is a problem with his real yàn foundation, there should be a collective offset, so if he really does the real yàn and makes it completely, he will find that there is a problem with the number jù, and after careful processing, he should be able to find the collective shift, and then, the number jù can be used. As a result, there was no deviation in his number at all, so it was determined that it was a fraud. Wei Zhenxue said a little proudly.

He said it easily, but finding such a number jù problem is actually not simple, and it takes a lot of calculations and a little luck to find out.

In particular, the collective is cheap, and some numbers jù 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 number jù becomes very much and very complicated - 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 actual yàn record and checked it line by line.

If you find someone else to fake, it will be embarrassing if you find that you have a problem with your number.

At the request of Yang Rui, Wei Zhenxue's actual record was very complete.

This is a good habit, when the actual yàn record can fully reflect the real yàn, the wrong real yàn becomes as valuable as the correct real yàn. If something goes wrong, you can find the cause through guò real yàn records.

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

But when Yang Rui progressed to the level of scientific research migrant workers, he gradually discovered the benefits of real records.

In many cases, the similarities and differences between the two reagents may be because the two bottles of reagents are from different manufacturers, and there is no complete record of the two reagents.

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

Next, Wei Zhenxue did several more realizations to determine the deviation value, and thus determined the final curve.

Compared with Li Xin's paper, Wei Zhenxue's practical yàn difficulty has increased, the difficulty of processing the number has also increased several times, and before the calculation, the probability of getting the desired conclusion has also decreased.

"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 he doesn't do it well, or the funds are not in place, he may indeed not be able to do it, but this is not a reason for fraud, he has one thesis is enough to graduate, pursue three papers, and then use fraudulent means to complete?" Yang Rui shook his head and said, "He just stared 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 still different to make a pure real room research.

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 real room, if you can earn back the real cost, I will give you a bonus!"
