Research starts with PhD students

Chapter 219 Is this what you call a difficult question? ! !

Tong Zhiguo took Zhang Shuo to visit the experimental base and explained the problems encountered in the research.

His team has completed the theoretical verification of "nuclear force splitting" and moved on to technical research, encountering a highly difficult technical problem.

The technical experimental process is to drive out the delayed-explosion field force ion group.

However, when the ion cluster escaped from the vacuum environment and was ejected at an extremely fast speed, it encountered problems when it hit the air.

For ion clusters, air resistance is not a big problem. The air resistance that ion clusters encounter is very small. The most important thing is that air particles will interact with the field force of the ion cluster, and the same nuclear force splitting phenomenon will occur. Because the air does not follow the movement of the ion cluster, the energy of the ion cluster is consumed.

It's like fire encountering wind, the tiny flame will be blown out directly, while the big fire will grow stronger and stronger.

Therefore, the solution is very direct, which is to increase the strength of nuclear force splitting, which can be understood as increasing the proportion of atomic nuclei participating in the reaction.

In this way, the energy gained is greater than the loss, and the reaction will not be interrupted by the influence of air.

This is true in theory, but it is very difficult to do in practice because the speed of nuclear force splitting increases exponentially. If too many atomic nuclei are involved in the reaction, the thermal intensity will increase exponentially, which may become extremely dangerous.

Therefore, in experiments, we dare not rashly increase the intensity of the reaction.

Zhang Shuo thought along the way and quickly came up with three methods, one of which was to increase the strength.

The second is to perform equilibrium calculations so that the loss caused by contact with the air is consistent with the increased heat. However, the research needs to consider the speed of the ion cluster, the air density, and involves issues such as thermodynamic aerodynamic equations. The calculations will become very complicated.

The third is to find new solutions to improve strength while ensuring safety.

He thought about it and learned about the main experimental equipment, and then he was arranged to rest.

After Zhang Shuo left, Tong Zhiguo sighed and said to Lu Ling, "This technical problem is indeed a bit too complicated. I don't think it can be solved in a short time."

"We can't rely entirely on Professor Zhang Shuo, and we need to conduct more rigorous argumentation."

"Yes."

Lu Ling also sighed and shook his head.

They have done a lot of work and conducted several basic experiments in succession, but so far there is no definite solution or even a definite direction for a solution.

"If there is really no other way, we can only keep doing experiments." Lu Ling said with pursed lips.

Doing a large number of basic experiments is also a solution. When there is enough experimental data, you will know what the key problem is and then slowly solve it.

The disadvantage of this solution is that it requires a lot of money and time, and it may not be solved even after a few years. However, there is still a large amount of basic experiments accumulated, which is equivalent to research progress.

They can increase the intensity little by little based on basic experiments to maximize safety issues.

In fact, the biggest worry during the experiment was an explosion.

If the ion cluster explodes in the experimental equipment and the field force affects the outer wall of the pipe, a violent explosion may occur. It may not be as strong as a small atomic bomb, but it is enough to destroy the entire experimental base.

……

The next morning, Zhang Shuo came to the experimental base again, and the project team held an internal data meeting.

This meeting will bring together data and basic computational information about the experiments in the hope of discovering something from the data that will lead to solutions to the problems.

In fact, Zhang Shuo already had an idea.

Among the three solutions he could think of, he chose the second method, which involved very complex calculations, but the data calculations were much simpler than finding a suitable solution.

The first method was too risky and was directly ruled out.

He has already established the task -

【Task 2】

[Research project name: Calculation of the balance between ion cluster excitation and air loss (difficulty assessment: C).]

【Progress: 3.127%.】

(The task can be canceled. Currently, the number of scientific research coins required to cancel the task is 0.)
(The remaining progress requires 97 scientific research coins.)
C-level tasks are relatively easy to perform, but in fact pioneering computing research is very complex, and there are many factors that affect computing.

Given the research content, even the slightest error in calculation may cause very big problems.

Lu Ling said that a lot of basic experiments need to be done, and the ultimate goal is to perform balance calculations to find a set of balance data that can ensure safety and maintain the field force.

The reason why they did not consider doing calculations is because there is a high possibility that something will go wrong in the calculations, and once a problem occurs, it may cause a violent explosion in the experiment.

Who can guarantee that the complex calculation data they make when researching a new theoretical technology is correct?

Zhang Shuo did not talk about the direction of solving the problem. He just attended the data meeting, listened to other people's reports, and took some notes with a pen.

The meeting as a whole was for each group to report data, and there was also data information related to previous experiments.

Zhang Shuo listened patiently to the end, and the system kept prompting him during the process -

[Task 0.453, progress +%. ]

[Task 0.901, progress +%. ]

[Task 0.08, progress +...]

By the end, the task progress had increased to 43%, which was still very fast.

After the meeting, Zhang Shuo continued to walk around the experimental base and visited the work locations and offices of various groups to learn some detailed information about the experimental research.

Detailed data of many modules were not reflected in the meeting.

These can also increase the progress of the task.

For two consecutive days, Zhang Shuo did the same thing. He went around the experimental base and communicated with every team leader, engineer, and data room staff.

At the same time, task progress is also growing rapidly.

On the afternoon of the third day, Zhang Shuo did not continue to wander around the experimental base, but went to a quiet office on the top floor of the office building.

He stayed alone in the office and began to do the final calculations.

At the same time, a leader named Wang came to the experimental base.

Teacher Wang is one of the leaders of the military. His work area covers military technology, and many matters require coordination with the Bureau of Industrial Science and Technology.

If a new ground weapon appears, the department in charge of Mr. Wang will be responsible for manufacturing, testing, and coordinating subsequent production work.

Tong Zhiguo's project studies a new military technology.

Teacher Wang was very interested in this and came over to follow the research progress. He took a tour of the base and learned about the problems encountered in the research.

Lu Ling sighed and said, "This problem has been stuck for a long time, and there is no clear solution yet."

"Don't you even have a direction?"

Teacher Wang frowned. He understood the difference between plan and direction.

If there is no solution, a solution can be come up with through careful discussion. However, if there is no direction to solve the problem, there is no way to talk about a solution.

He continued to ask, "What did Professor Zhang Shuo say?"

"Professor Zhang Shuo has been here for a few days and hasn't said anything. He has been trying to understand the situation."

Teacher Wang nodded easily. Lv Ling noticed Teacher Wang's expression and immediately said bitterly, "We have thought of many methods and gathered people to discuss it many times, but this is a new technology."

"The theory is completely new, and the technology is also completely new. I have never been exposed to it before."

"Moreover, the biggest problem in research is safety. If many experiments want to consider safety, they must control parameters."

"Teacher Wang, you also know about that explosion, right? It was at the level of a small nuclear bomb. If it happened at the experimental base, it would be unimaginable..."

Teacher Wang nodded seriously after hearing this, "Yes, safety is the most important thing."

Tong Zhiguo came over from a distance. He heard the conversation between the two and also talked about the research problem with Lv Ling. "It is indeed very difficult. We have thought of many ways, but in the end we can only think of piling up time."

"Only by doing a lot of basic experiments and accumulating a lot of data can we gradually increase the intensity while ensuring safety and strive to find the final balance point."

"How long will this process take?" asked Teacher Wang.

"Hard to say."

Tong Zhiguo pursed his lips and said, "Maybe it will take one year, two years, three years, or five years. We think that if we can solve it within three years, it will be very fast."

He reiterated, “This is a technology supported by a completely new theory.”

Teacher Wang agrees with this point. The reason why he actively came to the experimental base is because he is very interested in new technologies.

The new technology is to first create a group of high-energy ions, and then shoot the ion group out through a magnetic field. When it encounters high-density matter, it will explode.

This sounds like an ion cannon, which is in principle a nuclear cannon, but without any pollution.

Most importantly, ion clusters are easy to accelerate and encounter very little air resistance, so they can cover very long distances while also traveling at extremely high speeds.

If there is such a device on the ground, at worst it can be used as a top-notch air defense and anti-missile weapon.

Its biggest advantage is that the speed is fast enough and the release distance is far enough.

How fast is it?

Theoretically, the speed is calculated in Mach as the lowest unit.

Ions are not particles, but it is very easy to accelerate metal ions in a magnetic field. As long as there is enough power supply, the ion cluster can be accelerated to a maximum of 1/10 the speed of light in a circulating accelerator.

Of course, it is impossible in reality, but even one ten-thousandth of the speed of light is very scary, reaching 30 kilometers per second. It only takes less than a second to hit a fighter jet, and no fighter jet has time to react.

Speed ​​is just one of them.

Because what is fired out is an ion cluster, it is impossible for conventional radar to detect it.

This weapon is truly terrifying.

If it is in your own hands, the fear turns into safety and power.

……

After visiting the experimental base, Teacher Wang asked about Zhang Shuo's situation and then went to the office on the top floor.

Zhang Shuo has been staying in the office and hasn't come out.

There were two armed guards in front of the office door. When they saw Teacher Wang and Lv Ling approaching, the guard on the left reminded them, "Professor Zhang is working."

Teacher Wang stopped walking and sat down on a chair nearby. "Then let's wait."

This is also a sign of respect for Zhang Shuo.

Lu Ling also sat down and said, "I heard that Professor Zhang has been stuck in his office for a long time, and I don't know when he will come out."

"It doesn't matter if you wait a little longer."

Teacher Wang said this nonchalantly, and then sat at the door waiting.

The wait was half an hour.

Tong Zhiguo came over after finishing his work, but still didn't wait for Zhang Shuo to come out. He suggested waiting at the door for a while, and then said, "How about we leave first? When Professor Zhang Shuo is done, let someone call and tell him."

Teacher Wang looked at the time and stood up as well.

At this time, the door was pushed open.

Zhang Shuo came out with a document in his hand. He looked a little tired but energetic. When he saw Tong Zhiguo and Lu Ling were there, he immediately smiled and said, "I was just about to look for you."

After saying that, he turned around and noticed Teacher Wang, and immediately asked, "Who is this...?"

Lu Ling quickly helped to introduce.

After getting to know each other, several people went into the office together.

Teacher Wang sat down and couldn't help asking, "Professor Zhang Shuo, you have been here for a few days. Do you have any ideas about the problems encountered by Academician Tong's team?"

Tong Zhiguo and Lu Ling also looked at Zhang Shuo, but they did not hold out much hope because Zhang Shuo had only just learned about the experiment and the data.

Now, when it comes to solutions, it would be great if you can give a general direction of the solution.

"That's what I'm saying."

Zhang Shuo handed the document in his hand to Tong Zhiguo, then turned around and found a few sheets of manuscript paper from the pile on the table and handed them to Lu Ling, "This is the calculation result."

"What calculation?"

Tong Zhiguo was a little confused.

Lu Ling looked down at the densely written manuscript paper, his face filled with confusion and bewilderment.

Zhang Shuodao, "Calculation of the balance between ion cluster excitation and air loss."

"This is the method I came up with. I use precise calculations to solve the problem, calculate the most suitable intensity and the most suitable excitation time, and control the time that the ion group passes through the field force within a fixed range. This will balance the excitation state and the energy loss caused by contact with the air."

"The field force of the ion cluster can be maintained until it hits solid matter and then explodes."

Tong Zhiguo and Lu Ling were both stunned.

Teacher Wang was also a little stunned. He turned his head and looked at the two people in confusion. His eyes seemed to say, "Didn't you say it was difficult and would take at least a year or two? How come Professor Zhang Shuo has already come up with a solution?"

Tong Zhiguo asked in surprise, "You are calculating the balance between strength and loss? So many parameters... have you completed it?"

His face was full of incomprehension.

Lu Ling frowned and asked, "Balance calculations are based on existing data. Not to mention the complexity, how can we ensure accuracy?"

He asked directly to the point.

The project team also considered doing a balanced calculation of strength and loss, but because the content involved was too complicated, they could not think of a way to perfect the calculation, let alone ensure the accuracy of the results.

Experimental accuracy is very important.

Once there is an error in the calculation, the reaction intensity of the ion clusters inside the pipe will be too high, and the exponential increase may lead to an explosion.

This is an outcome that must not occur.

Zhang Shuo nodded slightly and said, "You are right to worry. Let's discuss it together."
