It’s very particular about which laboratory you go to first for experiments. ▲∴
According to Zhang Shengying's opinion, Ning Jing's data is wrong because the magnetometer in Ning Jing's laboratory has been tampered with. In this case, if one goes to Ning Jing's laboratory to do this set of experiments first, the results will be different.
It is consistent with the data currently used by Jingjing. In addition, even if different results are obtained in other laboratories, experts will believe that Jingping was only deceived by the equipment, and the responsibility lies with the equipment and not with Jingping.
On the other hand, first go to Du Xiangwang's laboratory to do experiments. Because Du Xiangwang's magnetometer is good, the results will naturally be different from the results in Ning Jing's paper. This is enough to prove that Ning Jing has made great achievements in data.
Fake. After that, even if Jingjing discovers that her magnetometer is malfunctioning, everyone will not believe her explanation, but will only think that she deliberately destroyed the magnetometer to cover up her previous fraud.
Because of this difference, Zhang Shengying insisted on going to Du Xiangwang's laboratory for verification experiments.
When things got to this point, Du Xiangwang, as the defense chairperson, had no choice. He cast a questioning look at Jingjing and received an affirmative smile. He didn't know whether Jingjing was confident or ignorant, but
Since Ning Jing had no other opinions and Meng Qilong personally came to the defense site to supervise the matter, he could only agree to Zhang Shengying's suggestion.
"In this case, everyone should come to my laboratory and have a look. It seems that our defense method will also need to change in the future. Some experimental data need to be verified on-site during the defense to prevent students from making any mistakes. In the paper
Leave regrets." Du Xiangwang laughed dryly, trying to lighten the atmosphere with a joke.
It is a pity that no one present can laugh, because this time the matter is too serious. No matter what the result of the experiment is, one of the two people, Ning Jing and Zhang Shengying, will be slapped in the face. Except for Zhang Shengying herself.
In addition, everyone else hopes that it is Zhang Shengying who is wrong and not Ning Jing. Firstly, because Ningjing is the pride of the school. Once the data is found to be falsified, the school cannot afford to lose its face. Secondly, everyone is quite dissatisfied with Zhang Shengying's approach.
Disdainful, it is really a shame for Peking University for a teacher to plot against his own students in such a way.
The group of people followed Du Xiangwang to the laboratory. Du Xiangwang asked everyone to sit down, and then said to Jingjing: "You can start doing experiments now. You can use all the materials and equipment needed."
The set of experiments that Ning Jing is going to do requires the use of samarium iron-arsenic specimens. Du Xiangwang is also currently doing research on iron-based superconductivity. There happens to be specimens of this material in the laboratory. Ning Jing has also visited Du Xiangwang in the past
She had done experiments here and was very familiar with the materials and equipment in the laboratory. She smiled at everyone and thanked everyone, then put on the white lab coat used for experiments and began to operate quickly.
Zhang Shengying did not sit down. She stood aside, staring intently at Ning Jing's every move. She was on guard against what Ning Jing would do. She could see that everything Ning Jing did was completely in compliance with the standards. It was consistent with the experimental design plan introduced in the paper.
Completely consistent, no flaws can be found.
Other experts sat aside. Some of them knew the experimental procedures, so they could naturally tell the difference. There were also several professors on the academic committee who were not engaged in superconducting research and did not understand the specific details of the experiment, but looking at Jing Jing
The operation was as smooth as a cloud. I also knew that this student was not simple. He was obviously used to doing experiments. The accusation of data falsification was probably untenable when applied to this student.
Jing Jing was the only person in the room who knew everything. Qin Hai asked her not to say anything in advance. He was waiting to give Zhang Shengying a powerful blow at this time. She calmed down and assembled the test piece skillfully as usual.
Start the instrument to start testing, and then write down the data one by one on paper.
The experiment process was not complicated. It took Ning Jing more than ten minutes to complete all the experiments. Under the supervision of Zhang Shengying, she entered the data into the computer, then called the statistical software to do some analysis, and sent the final data curve directly.
Gave it to the printer.
"Teacher Du, this is the result of my experiment just now. Compare it with the data in the paper to see if there are any problems." Ning Jing tore off the result from the printer and handed it directly to Du Xiangwang. Although he asked her
The person who raised the issue was Zhang Shengying, but Du Xiangwang was the chairman of the defense committee, so Du Xiangwang should have seen the result first.
Du Xiangwang took the printed result with some hesitation, opened Ning Jing's paper again, and compared the two with a surprised look on his face.
"How about it, Lao Du, is the result different?" Zhang Shengying asked proudly from the side.
"Xiao Zhang, take a look for yourself." Du Xiangwang handed the printed results and the paper to Zhang Shengying and said calmly. Although Zhang Shengying is also a middle-aged woman who has entered the fifth grade, she is younger than Du Xiangwang, so
In Du Xiangwang's mouth, he is still called Xiao Zhang.
Zhang Shengying took the two materials, took a quick look at them, and blurted out: "How could this happen!"
"Teacher Zhang, how are you?" Meng Qilong stepped forward and asked Zhang Shengying.
"This is impossible, completely impossible!" Zhang Shengying shouted hysterically.
"What's impossible?" Meng Qilong was a little annoyed. He snatched the printing paper and the paper from Zhang Shengying's hand, took a look at it, then slapped the two materials with the back of his hand, and said loudly: "Aren't the two results exactly the same?
?What are you saying is impossible!"
"Exactly the same?" The professors present exchanged glances with each other and felt as if a stone had fallen to the ground. Zhang Shengying said that Ning Jing's thesis data was falsified. Although everyone did not want to believe it, they did not dare to vouch for Ning Jing. But just now Ning Jing did
Everyone witnessed the process of the experiment with their own eyes. Zhang Shengying was also watching eagerly from the side. There was no chance that Ning Jing could falsify. If the experimental results just now are exactly the same as the data in the paper, then it means that Ning Jing did not falsify at all. The school's
Honor will no longer be stained with dust.
However, if Ning Jing did not falsify, why would Zhang Shengying categorically say that she did so?
Meng Qilong first attacked Zhang Shengying. He lowered his face and asked: "Teacher Zhang, you said that you have conclusive evidence that Ning Jing's paper data is fraudulent. How do you explain the current result?"
"This..." Zhang Shengying was completely confused. The result she originally imagined was not like this. She thought that after Ning Jing used Du Xiangwang's equipment to conduct experiments, she should get a set of data that was completely different from the one in the paper. At that time, Ning Jing
She would be at a loss, even if she jumped into the Yellow River, she would not be able to escape. But who would have expected that the expected scene did not appear, and now it is she, Zhang Shengying, who is in embarrassment.
"No, Lao Du, your magnetometer must be broken, otherwise such a result would be impossible. The correct result should be like this..."
As Zhang Shengying spoke, she opened a pile of information that she had been holding in her hand, pulled out a piece of paper, and held it up high for everyone to see.
"Isn't this result... the result that Jing Jing achieved just now?" Meng Qilong looked up, checked the paper in his hand, and then asked strangely.
"What?" Zhang Shengying was stunned again. She compared the results that Liu Jun gave her with Ning Jing's paper. She couldn't help being dumbfounded. Liu Jun's results were the same as Ning Jing's results. In other words, Du
There is absolutely no problem with Xiangwang's magnetometer.
"You...you definitely didn't include this set of data in your original paper!" Zhang Shengying pointed at Ning Jing and said loudly.
Jing Jing smiled coldly and asked, "Teacher Zhang, how do you know this set of data was not in my original paper?"
"I asked Liu Jun to read your paper, and he said that your data is completely wrong." Zhang Shengying said in a panic, shaking Liu Jun out.
"Did Teacher Zhang know that my data was wrong at that time?" Ning Jing asked, looking into Zhang Shengying's eyes.
Faced with Ning Jing's questioning, Zhang Shengying didn't know how to answer for a while. Saying that she knew was too despicable; saying that she didn't know, the experts on the scene were not stupid, so there was no way she could not see the truth of the matter. She
He hesitated for a few seconds, and finally he could only snort heavily from his nose, which was considered an answer.
At this time, the door of the laboratory was pushed open, and Chen Zongze walked in. He first glared at Zhang Shengying with hatred, then turned to Meng Qilong and said: "Principal Meng, there is something
I need to report to you."
"Teacher Chen, we are now discussing Ning Jing's graduation thesis..." Meng Qilong said hesitantly.
Chen Zongze said: "The thing I want to report is related to Ning Jing's graduation thesis. The thing is like this, after being reminded by Ning Jing, I just took a few students to inspect the equipment in the laboratory and found that we
The magnetometer in the laboratory malfunctioned, causing data errors in the magnetic properties experiments conducted by some students and teachers, including Ning Jing."
"Fault?" Meng Qilong was surprised, "How could there be a fault?"
"We have checked and found that someone has removed the back cover of the magnetometer and adjusted the resistance values of several variable resistors, which caused obvious deviations in the readings of the magnetometer," Chen Zongze said.
"Who did this? Haven't you taught students not to dismantle equipment casually?" Meng Qilong asked.
Chen Zongze said: "Our students all know that the experimental equipment is very precious and cannot be disassembled 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. It is completely
There is no need to disassemble the back cover. The only purpose of disassembling the back cover is to deliberately damage the equipment and cause the experimenter to obtain wrong results. As for the motivation for doing this, I don’t think it needs to be made too clear.”
Having said this, he turned his attention to Zhang Shengying and said coldly: "Teacher Zhang, are you really not aware of this matter at all?" (To be continued...)
