Fan Qingxue is a research expert in the field of superconductivity.

He has worked as a researcher in the superconductivity laboratory and has more than ten years of experience in the study of superconductivity mechanisms.

Although I have not led a team to do a large project, I have participated in theoretical research projects, and I have a lot of relevant experience.

As long as scholars who are familiar with Fan Qingxue, they all recognize his level in the field of superconductivity research.

Because of this, Wu Hui asked Fan Qingxue to come to Xihai University, just to let Fan Qingxue do some professional guidance on the research of the physics laboratory.

In Wu Hui's opinion, Fan Qingxue is definitely stronger than He Yi.

He Yi is a professor of physics at Xihai University and the head of the physics laboratory, but he does not have any experience in major projects, so his resume is naturally not as good as Fan Qingxue.

As for comparing it with Wang Hao, it is difficult to judge.

However, Wang Hao is a mathematician, not a professional in superconducting physics research, so there may be a lot of things he doesn't understand.

Fan Qingxue really didn't understand the theoretical meeting held in the physics laboratory.

In his experience, some research projects without a clue will focus on theoretical arguments, such as the replication experiment of communicating gravity, which belongs to the kind of research without a clue.

Because there are very few relevant materials, some references are not of great significance, so it is natural to carry out certain theoretical arguments.

What we are doing now is also an experiment on alternating gravity, but it has been possible to create an alternating gravity field, and the study is only about the influencing factors of the alternating gravity field, which is equivalent to a purely comparative research project.

What can be argued for a comparative research project?

This kind of research is to directly conduct experiments and adjust different parameters to analyze the results, and even if it is a demonstration, it is impossible to directly derive the results, so naturally there is no meaning.

For example, in the simplest way, study the relationship between current and resistance.

Adjust the voltage directly by conducting an experiment, and then measure the strength of the current, and the value of the resistance can be obtained.

It's the same with the current research.

As long as the parameters are continuously adjusted and then analyzed according to the results obtained, some interference factors can be identified and eliminated, so that relevant conclusions can be obtained.

Fan Qingxue thought so, but he obviously couldn't convince Wang Hao, because Wang Hao's goal was to surpass the two competitors.

It is impossible to surpass the other two large superconducting institutions in a normal way of research.

That's for sure.

In that case, there must be other methods.

Fan Qingxue could only sit on the side and watch.

The theoretical meeting officially began.

He Yi first spoke to elaborate on the theory, and then explained some factors that may be affected.

Everyone recorded it.

The process of the meeting is to let everyone explain their ideas for each factor.

Everybody was very positive because they already had the 'relevant experience' and knew that the argument was very important.

Even if it is only a comparative experiment, as Wang Hao said, if you want to surpass the other two large laboratories, you need to carry out more accurate theoretical demonstrations, so as to reduce the number of experiments and obtain more accurate data and results.

The study of the alternating gravity field may be related to many factors.

He Yi came up and said an important factor, "The factors related to superconducting materials are very critical. ”

The factor of superconducting materials is not only one factor, the first is the arrangement and layout of superconducting materials, that is, how to place superconductors and what to arrange superconductors.

This is also an important factor in supporting the generation of AC gravity.

The arrangement of superconducting materials is not just a tiled or simple spiral structure, but their arguments do not go into a detailed analysis, but only make some corrections to the original structure.

The argument was not carried out in great depth.

Wang Hao decided to continue the original 'four-node layout' in the first experiment, that is, to make the superconducting material in four fixed positions, greatly increasing the width of the material, which can be understood as the interval arrangement of two wires and small spheres.

This factor is unchanged.

A change in the layout of the superconducting material is to make the superconducting material 'bolder', or change the way it is arranged, to see if it can affect the final result.

The influence of superconducting materials also lies in the difference in materials.

At present, many superconducting materials have been discovered to achieve the requirements of superconducting state characteristics, which can be divided into low-temperature superconducting materials and high-temperature superconducting materials, and the influence of different superconducting materials on the AC gravity field may also be different.

Superconducting materials can also be divided according to the composition of materials, including oxides, metal alloys, organic materials, and even liquid materials.

The second factor is related to electricity, voltage and transmission power, which may have a direct impact, because superconducting materials theoretically have no resistance, and the current will be amplified many times, and even theoretically the current is infinite.

Of course, the actual current cannot be infinite.

"Critical current density may also be one of the influencing factors of the AC gravity field." Wang Hao emphasized a special sentence.

The critical current density is related to the critical magnetic field.

That's a complicated issue.

The first theoretical meeting does not need to go too deep, and everyone can analyze the surface factors together.

In addition to the effects of superconducting materials and electricity, there are other factors that may affect the AC gravity field.

There are many factors, including the influence of ambient temperature, altitude, air density, air flow, and even the spin of the earth, etc.

Of course, the influence of electromagnetic forces cannot be ruled out directly.

The current research is about excluding factors that do not have an impact and identifying those that have a direct impact.

Each of these items was discussed.

Everyone spoke enthusiastically and expressed their opinions.

Wang Hao is targeted for analysis, and He Yi is mainly responsible for controlling the process of the meeting and making a series of records.

Everyone has a clear division of labor.

The meeting also lasted for more than three hours and did not end until 1 o'clock in the afternoon.

Fan Qingxue has been sitting next to him and listening, watching the meeting be summarized one by one, but he always feels a little weird, because some factors are directly excluded by the 'theory'.

For example, the factor of air flow.

After a detailed discussion, it was concluded that the flow of air should not affect the alternating gravity field.

But doesn't this need an experiment to confirm it?

After the meeting ended, Wang Hao didn't forget the expert group, so he invited them to dine together, and Fan Qingxue also asked on the way, "Professor Wang, you directly excluded some factors from this meeting, which is a bit unscientific, right?" ”

Wang Hao nodded, "In fact, in my opinion, every factor should be proved by experiments, rather than eliminated through analysis." ”

"Then why ......?" Fan Qingxue didn't understand.

Wang Hao explained in one sentence, "It's very simple, because we have two very strong opponents, so we can't waste time on some factors that may not have an impact." ”

"We have to do our research more efficiently."

"Our funding is also limited, and now we only have funding from the school, and the provincial funding will have to wait a few days, not to mention the foundation." He shook his head helplessly.

Fan Qingxue had nothing to say when he heard it.

Although the process is indeed a bit unscientific, listening to Wang Hao's explanation, I feel that it is really like this, because of the limited funds and two strong opponents, it is impossible to design experiments for every factor to study.

The morning session was a theoretical argument in which they identified some of the 'probable' influencing factors and excluded some of the 'unlikely' related ones.

Experiments are designed based on the results of theoretical analysis.

One of the most difficult is the layout of the superconducting material, because it takes a while to prepare for the changes to the overall device.

The lab is busy in the afternoon, hoping to spend an afternoon preparing for the experiment tomorrow morning.

The members of the expert group left in the afternoon, and they did come to go through the motions.

Fan Qingxue did not leave.

One is because he came with a work task, which is to conduct research guidance in the physics laboratory.

This is the job that Wu Hui explained.

On the other hand, he was curious about the results of theoretical arguments.

Fan Qingxue felt that there were a lot of imperfections, as if some inexplicably came to a conclusion, and at the same time, he also wanted to see if the results of the experiment were as he thought, and there was no meaning.

This is his judgment, a judgment based on personal experience.

The atmosphere of the theoretical demonstration meeting was very lively and lasted for more than three hours, but it is difficult to say whether it will be effective or not.

Fan Qingxue still does not believe that theoretical arguments can have an effect on experiments.

By eight o'clock the next morning, the physics lab was already busy.

They are making final preparations for the experiment.

When the experiment was about to start, Fan Qingxue stood with Wang Hao, he thought for a long time last night, and decided to talk to Wang Hao again, "Professor Wang, I think the focus of this experimental research is on the layout of superconducting materials, and your four-node design is very critical. ”

"I listened to your meeting yesterday and there doesn't seem to be any argument for it, why is that?"

In Fan Qingxue's view, the layout of superconducting materials is the most important, because it involves a very complex design.

It is precisely because of this design that the alternating current gravity experiment has been successfully reproduced.

This is also the only difficulty in research.

Many people who know about the research believe that it is difficult to improve the design of the four nodes with ordinary comparative experiments.

Wang Hao heard Fan Qingxue's words and nodded, "This is confidential. ”

Fan Qingxue was stunned for a long time.

Wang Hao said seriously, "Professor Fan, I'll just put it bluntly, the key to the AC gravity experiment lies in the design of the four nodes, and the layout of superconducting materials. ”

"So there is no doubt that the layout of the superconducting material is directly related to the strength of the AC gravitational field."

"This correlation is likely to become the general direction of research, and it is difficult to achieve results in this direction in the comparative experimental research we are doing now."

"However, we will also explore in this direction. However, the design changes for the experiment should not be known to too many people. ”

"It's classified."

"Usually only a few core people come to discuss, and I don't talk about this at a meeting."

Fan Qingxue suddenly realized, but he still felt a little awkward in his heart, because he himself was also excluded. He asked with depression, "There shouldn't be any changes to the structural layout of superconducting materials in this experiment, right?" ”

He asked if the changes in the experiment were all as they were summarized yesterday, rather than adding something so-called 'classified'.

Wang Hao smiled, "That's still the direction of follow-up research, and now we are only experimenting on simple influencing factors." ”

As the two spoke, the experiment was ready.

Wang Hao, Fan Qingxue, He Yi, and Xiao Xinyu checked the equipment together, and after confirming that there was no problem, they walked away from the station and prepared to conduct experiments.

"Let's get started!"

After everyone was ready, Wang Hao directly let the experiment begin.

Equipment, officially launched!

With the hum of the machine, the personnel around the experimental equipment also began to get busy, constantly filling the delivery pipe with liquid nitrogen and other cooling materials, and there were special people who kept an eye on the voltage and power values.

Everyone else looked at the parameters of the detection equipment and the balloon changes above.

"It's floating!"

Fan Qingxue did not participate in the AC gravity replica experiment at the Basic Science Center of Capital University, but it was the first time he saw the AC gravity experiment, and he was a little shocked to find that the balloon suddenly floated up.

He had only read a few things about it.

Others in the lab have seen it once, and they are more concerned with the test parameters.

Soon someone reported the value, "As a rough estimate, our gravity has been reduced by about 2!" ”

"Keep experimenting!"

"Cool down again!"

"Increase the delivery power!"

After Wang Hao heard the value, he gave several orders in a row, and the others also got busy.

Soon another data was calculated, "gravity reduced by more than 2.3." ”

"Go on!"

Looking at the data shouted out one by one, Fan Qingxue felt dumbfounded, it was the first time he watched the AC gravity experiment on the spot, but he had seen the relevant information.

The AC gravity experiment conducted by the Basic Science Center of Capital University finally reduced the gravity between 1.71.8.

This value is already higher than the report of the physics laboratory.

Now it has increased to 2.3 or more, and the increase can be described as amazing.

Fan Qingxue didn't expect this result, he originally thought that even if there was an improvement, it would be only 0.1 at most, and it would be very good to reach the level of the reproduction experiment at Capital University at that time.

This level of improvement is difficult to explain, and it is necessary to do several experiments in a row to determine the influencing parameters.

The other two superconducting bodies do just that.

The first experiment in the physics laboratory increased the value by more than 0.5, such a huge increase that some influencing factors can be determined even through just one experiment.

Such an experiment is worth several experiments.

Fan Qingxue feels very unscientific, there is such a big improvement in the first experiment?

In addition, he did not understand the theoretical meeting, but felt that some conclusions were even hasty, as if they were only for the purpose of analyzing the greatest possibility, rather than rigorously using experiments to rule them out.

Fan Qingxue also felt that the people in the physics laboratory had a surprising 'admiration' for Wang Hao, and it could even be described as 'fanatical', as long as it was what Wang Hao said, no one questioned it.

The theoretical meeting is Wang Hao's hall of words.

With so many problems, when it comes to the experiment, the effect is so good, and it suddenly increases by more than 0.5?

Fan Qingxue stood aside and watched, completely unsure of what to say.

He found that his feelings were very similar to the first time he participated in the superconductivity experiment, he didn't know what to do, he didn't know why he came to the conclusion, he just had someone to do the experiment with him.

What was happening in front of him was beyond his knowledge and experience.

Ultimately.

The strength of the AC gravity field has increased to 2.52.6, which is about 0.9 higher than the experiment conducted by the Basic Science Center of Capital University.

This is a momentous development that everyone in the lab is very excited about.

After the experiment was over, they actively put the finishing touches on it and recorded all the data in detail.

After a busy morning, Wang Hao organized an experimental summary meeting in the afternoon.

Fan Qingxue didn't say a word during the whole process.

He felt that he had nothing to say, and he had come to guide the physics laboratory, but he found that he had no effect, and he didn't even understand how to conduct theoretical arguments, let alone why, that kind of argumentation could be so good.

"People do a comparative communication experiment, and the demonstration can greatly improve the efficiency, and I even think the argument is useless?"

"Is my idea too backward?"

"The results of the experiment proved that they are scientific, and I am not scientific......"

When Fan Qingxue was thinking lonely, Wang Hao finished summarizing the experimental data, he glanced at the audience and noticed Fan Qingxue.

He felt that he should pay attention to Fan Qingxue.

After all, the other party is a superconductivity expert, and Academician Wu Hui specially sent him to help.

Wang Hao made a gesture of invitation and said, "Professor Fan, you are a professional superconductivity expert, come and tell us about it, and give us some advice." ”

Everyone looked at it expectantly.

Fan Qingxue was stunned for a long time with his mouth half open, and finally said, "Your laboratory is perfect." ”

"I feel like there's nothing to say."

That night, Fan Qingxue took a plane back to the capital, and the next day he returned to his work.

Wu Hui was surprised that Fan Qingxue came back so quickly, and he came over and asked, "Didn't I ask you to guide the physics laboratory?" Why did you come back so soon? How's it going on their side? ”

Fan Qingxue held the information in his hand, raised his head and didn't speak for a long time.

In the end, he sighed and said, "Professor Wu, I went to Xihai University, and I feel that my level is still too bad." ”

"So when I came back, I wanted to read more information, increase my knowledge, and learn a little."

"As for the guidance ......"

Fan Qingxue paused as he spoke, and said with a wry smile, "At my level, how can I be qualified to guide them, I have been guided......"

There are no pop-up windows
