Chapter 102 Investigation Team: It turned out to be Zhou Xiaolong’s mistake!
"Super pressure-resistant alloy material?"
Wang Hao was very surprised when he saw the project name on the picture on his mobile phone, and finally understood why Xia Guobin was embarrassed to speak.
In the Alloy Materials Laboratory of Donggang University, the project he is engaged in is the research and development of super-stress alloy materials.
This project is very sensitive to him.
If he was really fired from Donggang University because of a calculation error that caused huge losses in the experiment, and someone came to him with this project, it could be said to be a humiliation to him to a certain extent.
Xia Guobin paid attention to Wang Hao's reaction and found that he acted very calmly. He breathed a sigh of relief and said, "I made up my mind to come and ask you after reading the recent media reports."
"Wang Hao, you know very well that I believed from the beginning that the Donggang incident was definitely not your problem. I had no other ideas, I just wanted to ask my old friend."
"Their research did encounter big problems, the most important ones occurring in the analysis of experimental data."
He listened for a while and continued, "Don't worry, although it is the same project, the project is being carried out by the Metal Research Institute of Xijing Jiaotong University, and even the funding source is different."
Wang Hao asked curiously, "Are there several organizations doing this project?"
Xia Guobin nodded, clasped his fingers and said, "There are three that I know of, one is Donggang University, one is Xijing Jiaotong University, and the other is the Institute of Aeronautical Materials."
"This is a super-resistant alloy material that is widely used. Institutions within the military industry must have similar projects."
He spoke in detail.
Research and development related to alloy materials are all national key projects, and high-performance alloy materials are an area of focus. Heavy industry companies, aviation industry groups, and the National Materials Fund will all provide support for related research and development.
The Alloy Materials Laboratory of Donggang University originally applied for the aviation group's research and development of super-pressure-resistant, high-temperature-resistant, and corrosion-resistant alloys. Later, the overall project was won by the Aeronautical Materials Institute.
The Alloy Materials Laboratory is also very powerful, and the project application preparations made are very complete. However, their basic experimental data are more inclined to develop and improve the toughness of alloy materials, so they allocate part of the funds to develop ultra-high pressure alloys.
The Metal Research Institute of Xijing Jiaotong University applied for a National Science Foundation project and was not a horizontal project supported by companies. Funding will definitely be severely restricted. The funding they received was more than three times less than that of the Alloy Materials Laboratory of Donggang University.
Due to financial constraints, every experiment must be carefully calculated, and we hope that every experiment can make research progress.
Now R&D has encountered the most critical problem, because each experiment brings a large amount of data, and the data analysis work of the institute can be said to have not made any progress. Researchers who specialize in data analysis, the conclusions drawn from the analysis are very important for the experiment.
Didn't bring any help.
In fact, researchers cannot be blamed for similar problems.
Data mining is a very complex field, and many conclusions drawn from data mining work are meaningless.
In the face of a huge amount of data, how can it be so easy to find some rules and promote the experiment to move in the right direction?
For researchers who focus on data mining, every experimental analysis can be said to be an exploration of unknown scientific research work, especially in the field of materials research and development. They spend a lot of time and energy and do a lot of data analysis to draw conclusions.
, maybe not as good as the result of an experimental error and luck.
This kind of analysis work does not mean that progress can be made through hard work.
Foreign materials research mainly relies on experience and manufacturing processes and technologies accumulated over many years.
The Metal Research Institute of Xijing Jiaotong University still hopes that the data mining work can make progress, which can promote the smooth progress of experiments and greatly reduce the loss of funds.
After learning that NanoLab had won Skyworth Technology's microsphere project, Professor Peng Hui from the Institute of Metal Research started talking to Xia Guobin. Xia Guobin naturally talked about the data analysis done by Wang Hao, which played a decisive role.
Then Peng Hui asked Xia Guobin to help introduce him, hoping to help the Metal Research Institute do some experimental data analysis.
Wang Hao was silent for a moment after listening, and then asked directly, "What are the benefits of my participating in this project? Professor Xia, you should know that this kind of data analysis work is very energy-consuming, and it may not be fruitful."
When Xia Guobin heard Wang Hao's question, he breathed a sigh of relief. What he was most afraid of was Wang Hao's resistance to the project.
It was originally a project in the hands of someone else and had nothing to do with him directly. I just wanted to ask an old friend a question. If I had any conflicts with Wang Hao because of this, it would be very unworthy.
"I don't know about this either," Xia Guobin said, "I'm just asking for help. If you are interested, I can ask someone from the metal laboratory to talk about it."
"Okay, we can talk."
Wang Hao agreed without much hesitation.
He is really interested in the project.
One is that his teaching courses include data mining content, such as probability theory and functional analysis, which are all related to data mining. Doing similar research will be very smooth.
The second reason is because of the project itself.
The predecessor was "failed" in the super-stress alloy material project, and was slandered by the alloy laboratory that the data calculation was wrong.
Even if it is just to prove myself or make up for the regrets of my predecessor, I must take over and give it a try.
…
The new data analysis work needs to be discussed with the Metal Laboratory of Xijing Jiaotong University, and the main work in the school still revolves around the Mason Mathematical Science Laboratory.
The professors and leaders of the School of Computer Science and the School of Science are all busy trying to apply for the establishment of the Mason Mathematical Science Laboratory.
Wang Hao also wrote a related report to help apply for the establishment of a new laboratory, the Mason Mathematical Sciences Laboratory, which revolves around his research results and can be said to be his laboratory.
Therefore, his research results on Mersenne primes also attracted much attention.
The relevant paper has been confirmed to be published in the next issue of "New Advances in Mathematics". The main considerations are high influence and fast publication speed. His paper can directly jump in the queue.
Such a big achievement must not only be about publishing papers, but also related academic reports. The academic reports will not consider foreign conferences, because there will be no top mathematics conferences to be held in the next six months.
Therefore, Wang Hao still considered publishing results reports in China, and he received invitations for three academic reports.
One came from the Chinese Mathematical Society. The Chinese Mathematical Society established a new branch and held an academic report meeting.
The meeting of the Mathematical Society is suitable for publishing results, but the main problem is that it is held a bit late, in April next year, and there are still more than four months left.
The other is an invitation to an international conference from Jinkai University.
During the winter vacation at the end of February, Jinkai University will hold a computer application conference. Considering that it is only a conference in the computer field, the content is relatively inappropriate.
Finally, there was the invitation from Shuimu University.
This invitation is quite valuable. It comes from Academician Qiu Chengwen, a Fields winner. He invited Wang Hao to give a report on results at the Mathematical Science Center of Shuimu University.
Because I only went to the Mathematical Science Center to give a report and it was not an academic conference, I had more free time for my report.
Wang Hao was still hesitating.
He prefers to give a report at Shuimu University rather than being assigned to any meeting.
The latter is relatively troublesome.
However, when it comes to making the results report, one has to wait for the Mersenne number analysis from Penguin, and the other has to wait for the paper to be published.
Penguin will probably have the results soon and will find an appropriate time to announce the results.
Papers are always published in early January.
Wang Hao is not in a hurry. He still wants to wait until the next year to announce the results so that he can take a proper rest.
In the next few days, he started to live a normal life. He was not in a hurry to do any research. He just went to class as normal, accumulated some inspiration, and read books to accumulate knowledge when he had time.
Although life is relatively dull, the inspiration value is still growing.
[Task 3: Research on the probability of prime number distribution (difficulty: S).
[By consuming teaching coins, you can obtain the probability of obtaining the inspiration value related to it. 】
【Inspiration:36 points.】
"It's thirty-six o'clock!" Wang Hao was quite satisfied with the inspiration value.
This value does not seem high, but considering the research and development of S-level difficulty, every achievement can be said to be world-class, and a score of more than 30 points can be said to be very high.
While Wang Hao was living an ordinary life and slowly accumulating inspiration points, the investigation team of the Alloy Materials Laboratory of Donggang University also made significant progress in its work.
The investigation team carefully reviewed all the data during the experiment, as well as the "erroneous data" submitted by the laboratory, and found that there were no problems with Wang Hao's work.
Chen Jianlin said, "Although there is no problem with the calculation, the data submitted to Professor Ma Wenjun is indeed wrong."
"We have proven through several experiments that the data must be problematic."
This problem troubled the investigation team. A materials expert named Qian Minghao spent several hours sorting out the data and finally found the problem.
Qian Minghao thought he had discovered the key, and explained excitedly, "Professor Wang Hao's calculations are indeed correct, but the submitted data itself has problems."
"You can make a careful comparison. These erroneous data are very similar to the other group, but the values are also very different."
"One is in the range of 0.1~1, and the other is in the range of 0.05~0.5." Qian Minghao was talking about the element ratio values of the two sets of data.
The corresponding element content values of the two sets of data are all below one percent. Without careful inspection or non-professionals, it is impossible to find the problem.
Qian Minghao noticed this detail, "Normally speaking, elemental sulfur is an impurity, and its proportion will most likely not reach as high as 0.6%. I just noticed this data and discovered the problem."
The others immediately followed and looked over.
If it weren't for Qian Minghao's introduction, they wouldn't have noticed the problem with this set of data at all, because their main focus was on 'Wang Hao's work', that is, the calculation of experimental data, and they didn't notice the problem at all.
The data itself is problematic.
After careful study, I discovered that there was indeed a problem with the submitted data. It should be that the two sets of data were mixed up.
Because of this, when the data is calculated and submitted for analysis, a large number of errors will be found, which will directly affect the experiment itself.
Qian Minghao suddenly felt a little proud. He was a professor of materials at Donggang University of Technology, but his main field was chemical materials, not alloy materials, but he could find problems that no one else could find.
Doesn’t this prove outstanding ability?
Others also agreed with Qian Minghao's conclusion. The problem did lie in the data submission. It should be said that there was a problem with the initial experimental data record reporting and had nothing to do with Wang Hao's data calculation.
When the investigation team came to a conclusion, it immediately notified the Alloy Materials Laboratory.
Chen Jianlin was surprised when he saw the investigation results. Qian Minghao took the initiative to help explain some of it, and he suddenly said, "So that's it. I've always been surprised that I couldn't find the problem. I thought it was Professor Wang Hao's calculation error, but I didn't expect it!"
"
He sighed with a face full of emotion, "We have wronged Professor Wang Hao. It's really..."
He gritted his teeth as he spoke, with regret on his face.
Ma Wenjun also suddenly said, "At that time, I was still wondering why so many data were wrong. That's right. Wang Hao had just joined the laboratory. He is a Ph.D. in mathematics and didn't know much about materials research. No wonder he was confused when he first saw the data.
, can’t find the problem.”
This sentence explains why the experiment was conducted for three months before problems with the data were discovered.
Wang Hao didn't know much about materials research, so he couldn't tell if there were any deviations in the initially reported data. After he made the calculations and sent them to Ma Wenjun, they were all final conclusion values, so naturally he couldn't find any problems.
There are two key points. One is that there is an error in data reporting, and the other is that Wang Hao does not understand material research.
The latter is obviously unimportant.
Because Wang Hao's job is to do data summary calculations, it is understandable that he could not find the initial data, and there were no errors in his own calculations.
The former must be dealt with.
"Who is responsible for reporting experimental data?" the person in charge of the investigation team asked directly.
Chen Jianlin stood there silently for a long time, as if he mustered up a lot of courage, and then uttered a name, "...Zhou Xiaolong."
Ma Wenjun explained from the side, "Zhou Xiaolong is Professor Chen's student and has been with him for more than ten to twenty years."
The people in the investigation team suddenly realized.
This matter has become a big deal. Wang Hao was fired from the school because of data errors. The key figures involved in the investigation will definitely be punished, otherwise there will be no way to calm public opinion.
It is impossible to say that Wang Hao was fired from the school due to a calculation error, and now that the investigation has revealed that it was someone else, it will not be dealt with, right?
It's definitely a dismissal.
"No wonder Professor Chen is like this..." The people in the investigation team understood immediately.
Now that the investigation has results, the remaining work is to announce the results. As for Donggang University and the Alloy Materials Laboratory, how to deal with Zhou Xiaolong who made the mistake has nothing to do with the investigation team.
A group of people left cheering, talking and laughing.
Qian Minghao's voice was the loudest because he felt that he had found the key and could be said to be the person who contributed the most to the investigation. He could brag about it when he returned home.
In the office inside the laboratory, only Chen Jianlin and Ma Wenjun were left.
The two of them no longer felt as surprised or sad as before. They looked at each other and felt much more relaxed.
It took a long time.
Ma Wenjun said, "Is this really good?"
Chen Jianlin sneered, "What else can I do? I don't want to push Xiaolong out, but if I don't push one out, this matter will not end."
"When doing data, I insist that Wang Hao is wrong. A whole row of data is wrong. Will anyone believe it? The investigation team doesn't believe it."
"Push Xiaolong out, and this matter can end here. The experimental issue has nothing to do with Wang Hao. The stain on him is gone. In the future, no matter whether he gets a Fields award or any other award, no matter how big he gets,
The results can be used to draw a clear line between us, and no one will talk about the Alloy Laboratory again."
Ma Wenjun nodded.
When Zhou Xiaolong launched it, he not only had an explanation to the investigation team, but also to public opinion. It was an error in the initial data report. When digging deeper, the person who made the error was Chen Jianlin's student, a heavyweight researcher at the Alloy Laboratory.
Public opinion, what else can be said?
At that time, if the school directly fires a professor and a materials researcher, it will be enough to satisfy public opinion, and no one will talk about it in the future.
Ma Wenjun thought about it carefully and felt that launching Zhou Xiaolong was the best choice. He pondered and continued, "But all our data have been submitted, and this project is suspended. If there is a similar study completed, data comparison will still be done."
problem found."
All data is fabricated, and as long as it is fabricated data, there is a possibility that it will be exposed.
"Don't worry."
Chen Jianlin shook his head and said, "We are the only ones doing this project now. Xijing Jiaotong University and the Institute of Aeronautical Materials. At the Institute of Aeronautical Materials, the main direction is to add rare metals to nickel-iron alloys, and super-stress alloys are ranked behind."
"Xijing Jiaotong University..."
"With that little funding, what research can be done?" Chen Jianlin curled his lips disdainfully, "I still know how much Peng Hui weighs."
