Material Empire

It is very particular about which laboratory to do the experiment first.

According to Zhang Shengying's thinking, Tranquility's data is wrong because the magnetometer in Tranquility's laboratory has been tampered with. In this case, if you go to Tranquility's laboratory to do this set of experiments first, the results will be consistent with the data that Tranquility is currently using. In addition, even if different results are obtained in other laboratories, experts will believe that Tranquility is only deceived by the equipment, and that the responsibility lies with the equipment, not Tranquility.

Conversely, first go to Du Xiangwang's laboratory to do experiments, because Du Xiangwang's magnetometer is good, and the results will naturally be different from the results in Ning Jing's paper, which is enough to prove that Ning Jing has created a problem in the data. fake. After that, even if Tranquility finds that her magnetometer is malfunctioning, everyone will not believe her explanation, but will only think that she deliberately destroyed the magnetometer to cover up the previous falsification.

Just because of this difference, Zhang Shengying insisted that Ning Jing go to Du Xiangwang's laboratory to do verification experiments.

When the matter developed to this point, Du Xiangwang, as the chairman of the defense, had no choice. He cast a questioning look at Tranquility, and what he got was an affirmative smile. He didn't know whether Tranquility was confident, or ignorant and fearless, but since Tranquility had no other opinions, and Meng Qilong personally came to the defense site to supervise the matter, he could only agree with Zhang Shengying's suggestion.

Since this is the case, everyone should go to my laboratory to have a look. It seems that our defense method will also be changed in the future. Some experimental data need to be verified on the spot during the defense, so as to prevent students from making any mistakes. In the paper Leave regrets. Du Xiangwang giggled dryly, trying to ease the atmosphere with a joke.

It's a pity that everyone present couldn't laugh, because this time the incident was too serious. No matter what the result of the experiment was, one of Ning Jing and Zhang Shengying would be slapped in the face. Except for Zhang Shengying herself, everyone hoped that Zhang Shengying was the one who was wrong, not Tranquility. Firstly, it was because Tranquility was the pride of the school. This approach is quite disdainful. It is really a disgrace to Beijing University for a teacher to use such a method to calculate his own students.

A group of people followed Du Xiangwang to the laboratory. Du Xiangwang asked everyone to sit down, and then said to Tranquility: You can start the experiment now. You can just use all the materials and equipment you need.

The set of experiments that Tranquility is going to do requires the use of samarium oxide iron arsenic specimens. Du Xiangwang is currently doing research on iron-based superconductivity, and there are test pieces of this material in the laboratory. Tranquility also went to Du Xiangwang to do experiments in the past, and she was very familiar with the materials and equipment in the laboratory. She smiled at everyone and thanked everyone, then changed into a white coat for experiments, and began to move quickly. to operate.

Zhang Shengying didn't sit down, she stood aside, staring at Ning Jing's every move, guarding against what Ning Jing did. She could see that everything Tranquility did was in full compliance with the specifications, and was completely consistent with the experimental design presented in the paper, and there were no flaws to be found.

Other experts sat on the sidelines, and some of them understood this set of experimental procedures, so they could naturally see the way. There are also a few professors from the academic committee who are not doing superconducting research and do not know the specific details of the experiment, but seeing the peaceful operation as smooth as flowing water, they also know that this student is not simple, obviously he is used to doing experiments, and the data is falsified This accusation is probably untenable when applied to this student.

Tranquility was the only person in the room who knew everything about the situation. Qin Hai told her to keep quiet in advance, in order to give Zhang Shengying a powerful blow at this time. She concentrated and calmed down, as usual, skillfully assembled the test piece, started the instrument to start the test, and then wrote down a group of data on paper.

The experiment process was not complicated, and it took Tranquility more than ten minutes to complete all the experiments. Under the supervision of Zhang Shengying, she entered the data into the computer, then used statistical software to do some analysis, and sent the final data curve directly to the printer.

Ms. Du, this is the result of my experiment just now. You can compare it with the data in the paper to see if there is any problem. Tranquility tore off the result from the printer and handed it directly to Du Xiangwang. Although it was Zhang Shengying who challenged her, Du Xiangwang was the chairman of the defense committee, so Du Xiangwang should be the first to see the result.

Du Xiangwang took the printed result with some hesitation, and then opened Tranquility's paper, compared the two, with a surprised expression on his face.

How is it, old Du, the result is different? Zhang Shengying asked triumphantly from the side.

Xiao Zhang, take a look by yourself. Du Xiangwang handed the printed results and paper to Zhang Shengying, and said calmly. Although Zhang Shengying is also a middle-aged woman in Benwu, but because she is younger than Du Xiangwang, she is still called Xiao Zhang in Du Xiangwang's mouth.

Zhang Shengying took the two documents, looked at them, and couldn't help blurting out: How could this happen!

Mr. Zhang, how is it? Meng Qilong leaned forward and asked Zhang Shengying.

This is impossible, absolutely impossible! Zhang Shengying shouted hysterically.

What is impossible? Meng Qilong was a little annoyed. He snatched the printing paper and papers from Zhang Shengying's hand, took a look, then patted the two materials with the back of his hand, and said loudly: Aren't the two results exactly the same? ? You said it was impossible!

Exactly the same? The professors present exchanged glances, feeling like a stone had fallen to the ground. Zhang Shengying said that Tranquility's paper data was falsified. Although everyone didn't want to believe it, they didn't dare to vouch for Tranquility casually. However, everyone witnessed the process of Tranquility's experiment just now, and Zhang Shengying was also staring at it. Tranquility cannot possibly have the opportunity to fake it. If the results of the experiment just now are exactly the same as the data in the paper, it means that Tranquility has not falsified at all, and the school's honor will not be dusted.

However, if Tranquility did not make a fake, why would Zhang Shengying say that she did it?

Meng Qilong was the first to attack Zhang Shengying. He lowered his face and asked, Mr. Zhang, you said that you have solid evidence to prove that Tranquility's paper data was falsified. How do you explain this result?

This... Zhang Shengying was completely dumbfounded. The result she had imagined was not like this. She thought that after using Du Xiangwang's equipment for experiments, Tranquility should get a set of data that was completely different from that in the paper. At that time, Tranquility You will be at a loss, even if you jump into the Yellow River, you will not be able to cleanse yourself. But unexpectedly, the expected scene did not appear, and it was her, Zhang Shengying, who was in embarrassment now.

No, Lao Du, your magnetometer must be broken, otherwise such a result would not be possible. The correct result should be like this...

As Zhang Shengying said, she opened the stack of materials she had been holding in her hand, took out a piece of paper, and held it up high for everyone to watch.

This result...isn't it the result of Tranquility just now? Meng Qilong looked up, compared the papers in his hand, and asked strangely.

What? Zhang Shengying was taken aback again. She compared the result Liu Jun gave her with Tranquility's thesis, and she couldn't help being dumbfounded. Liu Jun's result was also the same as Tranquility's, that is to say, Du Xiangwang's magnetometer is completely fine.

You...you definitely didn't have this set of data in your original paper! Zhang Shengying pointed at Tranquility and said loudly.

Tranquility smiled coldly and asked, Mr. Zhang, how do you know that this set of data is not in my original paper?

I asked Liu Jun to read your paper, and he said that your data is completely wrong. Zhang Shengying panicked, shaking Liu Jun out.

At that time, did Teacher Zhang know that my data was wrong? Tranquility asked, looking into Zhang Shengying's eyes.

Facing Tranquility's questioning, Zhang Shengying didn't know how to answer for a moment. Saying that I know it seems too despicable; saying that I don’t know, the experts on the scene are not stupid, how can they fail to see the truth of the matter. She was silent for a few seconds, and finally could only snort heavily from her nose, which was regarded as an answer.

At this time, the door of the laboratory was pushed open, and Chen Zong walked in. He first gave Zhang Shengying a hard look with hatred, then turned his head to Meng Qilong, and said, Principal Meng, there is something I need to report to you.

Mr. Chen, we are now discussing Tranquility's graduation thesis... Meng Qilong said hesitantly.

Chen Zong said: The thing I want to report is related to Tranquility's graduation thesis. The thing is like this. After being reminded by Tranquility, I just took a few students to check the equipment in the laboratory and found that we The magnetometer in the laboratory failed, resulting in data errors in the magnetic performance experiments done by some students and teachers, including Tranquility.

Fault? Meng Qilong was startled, How could there be a fault?

We have checked. Someone removed the back cover of the magnetometer and adjusted the resistance of several variable resistors, which caused a significant deviation in the reading of the magnetometer. Chen Zongze said.

Who did this? Haven't you taught the students not to disassemble the equipment casually? Meng Qilong asked.

Chen Zong said: Our students all know that the experimental equipment is very precious, and it is impossible to disassemble it at will. Besides, there are several adjustment knobs on the outside of the magnetometer. If you need to correct the zero value, you only need to adjust it outside. There is no need to remove the back cover. The only effect of removing the back cover is to deliberately damage the device and make the experimenter get wrong results. As for the motivation for doing this, I don’t think it needs to be too clear.”

Speaking of this, he cast his eyes on Zhang Shengying, and said coldly: Mr. Zhang, do you really know nothing about this matter?
