Material Empire

Xiao Weihao left with his people, and before leaving, he cleaned up Zhang Shengying's laboratory as if no one had ever entered. Qin Hai could clearly see that the two socks Lu Xiaotong was wearing were not the same color, and he was obviously not the kind of person who could do housework, but his ability to disguise the scene was impressive, which could be regarded as a specialization in art.

With the files copied from Liu Jun's computer, Qin Hai returned to the quiet residence. Although the name is not right, this is already the home of the two of them. When Qin Hai entered, Tranquility was busy cooking, and when she saw Qin Hai coming back, she asked anxiously, How is it? Did you find any results?

Your name is Serenity? Qin Hai asked Tranquility with a smile.

Tranquility blushed a bit, and said, Those boys gave me nicknames behind their backs, and they thought I didn't know...By the way, why did you think of asking this?

In Liu Jun's computer, a file named Serenity was found. We guess this file is related to you. Qin Hai said.

What's in the file? Tranquility asked.

Qin Hai shook his head: Liu Jun wrote the document on another computer, and then took it to the laboratory on a floppy disk to print it. Unless you search Liu Jun's personal computer, there is no way to determine the contents.

That's it... Tranquility frowned, When did it happen?

A month ago. Qin Hai said.

A month ago? Tranquility thought about it seriously, and then said: I remembered it when you said that. Liu Jun hasn't struck up a conversation with me for a long time, and he suddenly asked me about it more than a month ago. About writing a graduation thesis, and asked me if I have recently submitted a manuscript to an international journal.”

How did you answer? Qin Hai asked.

I didn't think much about it, so I told him about my experiment at that time, and said that I just wrote an article and was going to submit it to the Superconductivity magazine. Tranquility said.

Is it about samarium oxide iron arsenic? Qin Hai asked.

Yeah, how do you know? Tranquility said in surprise. She occasionally discusses academic matters with Qin Hai, but because she has done a lot in iron-based superconductivity, Qin Hai's knowledge is no longer enough to communicate with her, so she never talked to Qin Hai about samarium The case of iron oxide arsenic. Qin Hai's ability to ask this question was obviously related to Liu Jun.

Qin Hai took out a three-inch floppy disk from his pocket and said, We found several papers on SmOFeAs in Liu Jun's computer, which were printed at the same time as the paper called Serenity.

Let me see. Tranquility took off the apron she was wearing when cooking, wiped her hands, snatched the floppy disk from Qin Hai's hand, and ran to her computer.

Research on the magnetic properties of samarium oxide iron arsenic... Tranquility flipped through Liu Jun's article, frowning, How could he do experiments in this area, it has nothing to do with his research direction.

Could it be that he wants to plagiarize your ideas, publish a paper before you... and then accuse you of plagiarism? Qin Hai guessed wildly. Accusing an academic of plagiarism is arguably the most effective form of dirty water. If a scholar is stained with the word plagiarism, his academic future is basically over, and his previous academic reputation will also be wiped out.

If Liu Jun can publish an article with similar content before Tranquility, Tranquility's subsequent articles will be suspected of plagiarism. However, this kind of trick is difficult to stand up to scrutiny. The big cows in the academic world are more or less discerning. It is clear at a glance who can make what kind of results. It is said that Tranquility plagiarized a researcher who has never done research on iron-based materials. It is difficult to accept this statement from the thinking of doctoral students who have been exposed to iron-based materials.

Tranquility carefully read Liu Jun's articles, then shook her head, and said, It doesn't look like what you guessed. Liu Jun's articles are not papers, they are just experimental reports. He just repeated what I did. I have done a few experiments, and they are not considered the most core experiments. Also, the results he got are obviously different from mine, which is clearly a mistake...

You said the results were different? Qin Hai asked sensitively.

Yes. Tranquility said, she opened a file of her own and pointed it to Qin Hai: Look, the result of my experiment is such a curve, his result is completely different from mine, and the two curves do not match at all. .”

Is it the same experiment? Qin Hai asked.

From his description, the experimental design is exactly the same. Tranquility said.

The same design, completely different results, which can't even be explained by experimental errors, this is the problem. Qin Hai muttered, thought for a while, looked at Tranquility and asked, Why do you say yes? Was he wrong? Why can't it be you?

How could I be wrong? Tranquility said angrily, I have done so much research anyway, if a magnetic property experiment can be wrong, then don't apply for a doctorate, you have to go back to the furnace and go to undergraduate.

Liu Jun is also a doctor of superconductivity, why did he make a mistake? Qin Hai said.

Yeah... Ning Jing was a little puzzled. The measurement of the magnetic properties of materials is not a complicated experiment, especially for those who are engaged in superconductivity. It can be explained, but it is unreasonable to say that it is a completely wrong result.

What if there is a problem with the experimental equipment? Qin Hai reminded.

What could be wrong with the experimental equipment? Tranquility said, It's just a magnetometer... By the way, I remembered that if Liu Jun has done this set of experiments, the magnetometer he used should be the same as ours. lab, and I use the same one. At that time, he said that Mr. Zhang’s magnetometer was out of order, and he wanted to borrow it from our laboratory. Mr. Zhang came forward to talk to Mr. Chen, and Mr. Chen agreed. .”

So that's it. Qin Hai nodded. Although he didn't have conclusive evidence, he was already able to guess the mystery.

What did you say so? Tranquility asked cutely. She really stayed in the laboratory for too long, and she had no idea of ​​the dangers of the human heart. Speaking of which, Ning Zhongying is a treacherous and cunning man with a delicate heart, but he has not passed it on to his sons and daughters at all. Whether it is Ning Mo or Tranquility, they are both honest and honest people. shocked.

It's hard to say now, after dinner, let's redo your experiment. Qin Hai said.

Then what else is there to eat, let's go now. Tranquility was in a hurry, something was hanging in her mind, how could she still have the appetite to eat, if she didn't figure this out, she wouldn't be able to taste even the best meal.

Qin Hai had no choice but to put on a sad face, grabbed the car keys, and went out with Tranquility.

The two drove to the superconducting center and went straight to the quiet laboratory. It was noon at this time, and everyone went to the cafeteria to eat. The laboratory was empty and there were no outsiders. Without Qin Hai's instructions, Tranquility directly took out the sample of samarium oxide iron arsenic from the material cabinet, turned on the magnetometer, and began to repeat the experiment he had done in the past. Qin Hai also came from a material background, and was no stranger to this kind of experiment, so he helped her from the sidelines, and at the same time carefully observed her operation process, judging if there were any mistakes.

The whole experiment was done perfectly, and with Qin Hai's professional eyes, there was nothing wrong with it. Tranquility entered the experimental data into the computer, called up the software and typed a series of commands, and a curve appeared on the screen. Qin Hai took a closer look and found that this curve was the same as the result that Tranquility had obtained before, but it was quite different from Liu Jun's result.

Look, isn't that right? Tranquility pointed to the screen and said to Qin Hai, How could I make a mistake in such a simple experiment?

No hurry, let's try another device. Qin Hai said calmly.

Why? Tranquility asked in surprise.

Let's talk after we're done, Qin Hai said.

There are many laboratories in the research center, Qin Hai called the administrator, asked him to take the key to open the door of Du Xiangwang's laboratory, and then ordered Tranquility to do the same experiment again with Du Xiangwang's magnetometer.

Huh?

Just after two or three data came out, Tranquility's expression changed. With the same materials and the same experimental procedures, the results obtained by Du Xiangwang's magnetometer are completely different from those she has done before. These data are very familiar to her, she can judge the difference just by looking at it, and this difference is definitely not a normal experimental error.

Teacher Du's magnetometer is broken? Tranquility said, before Qin Hai could answer, she had already realized it: No, the magnetometer in our laboratory is broken!

At this time, if Tranquility still can't think of what's wrong, then her Ph.D. will be sent as a phone bill. The magnetometer in Tranquility’s laboratory reads differently from the magnetometer in another lab, and Liu Jun, who was suspected of harming Tranquility before, just borrowed the magnetometer and secretly conducted a set of comparison experiments , and got a different result from Tranquility, but kept it secret. How could there be no conspiracy in this?

Obviously, Liu Jun must have tampered with the magnetometer in Tranquility's laboratory, causing Tranquility to get a set of completely wrong results. If Tranquility uses such results to participate in the doctoral dissertation defense, it is a data distortion. If someone is interested in provoking it, the nature of this matter can be raised to academic fraud.

As a doctor who is about to graduate, academic fraud is also a fatal blow. Once this allegation is confirmed, the academic committee must revoke her degree and deprive her of the qualification to apply for a degree in the future. That is to say, this matter Enough to keep her forever.

As for the article that Liu Jun printed in the laboratory before, combined with his question about Tranquility’s submission, it can be guessed that this must be a report letter to the Superconductor magazine, and the content of it is also conceivable.

The whole plan can be described as exhaustive and vicious, but unfortunately only one thing was left out, and that was Qin Hai.
