Scholar’s Advanced Technological System

The interview was scheduled for a week later.

Since this time, Lu Zhou has basically been working on small-scale projects for controlled fusion.

In order to increase the peak temperature of bubbles in the working fluid, several old professors at the Luzhou Institute of Acoustics also tried to improve the ultrasonic generator. By removing the acoustic suspension stabilization device on the generator, the energy of the load in the ultrasonic wave was increased. The maximum sound pressure on the air bubbles has increased from 15 times atmospheric pressure to 30 times.

Of course, this is not without cost.

Without the acoustic suspension stabilization device, the bubbles in the solution cannot stably float in the center of the container.

However, sonoluminescence originally did not need the bubbles to be floating in a certain position in the container steadily, so this side effect would not matter.

After updating the experimental equipment, Lu Zhou and Sheng Xianfu immediately repeated the experiment again, using two gases of xenon and deuterium and tritium, respectively, and observed the temperature of the bubble and the key neutron recovery rate.

The completed experiment report was handed to Lu Zhou, and Sheng Xianfu said with a mixed expression on his face.

"The situation is still not optimistic. The maximum peak temperature can reach about 10 million Kelvin, but the lowest is only about 500,000 Kelvin."

Looking at the experiment report in his hand, Lu Zhou frowned.

"Is the deviation so big?"

Sheng Xianfu nodded his head solemnly: "The temperature change observed through the black body radiation is quite unstable, and I don't know if it is because of our observation method that is wrong, or for some other reason."

If the collapse of each bubble can reach a high temperature of 10 million Kelvin, taking into account factors such as volume shrinkage, it is still possible to use a pulse ignition method to stabilize the fusion reaction. however

Lu Zhou continued to ask, "What about the neutron proliferation rate?"

Sheng Xianfu hesitated a bit: "It has improved ... but it is still far from stable, controlled fusion."

Lu Zhou pondered for a moment, and asked, "How is the new experimental container prepared?"

Sheng Xianfu: "The nuclear industry group has already completed it, and it will probably be delivered tomorrow."

Hearing this sentence, the expression on Lu Zhou's face finally relieved a bit.

Putting the experiment report on the table, he spoke.

"That's it for today's experiment, check the equipment tomorrow. Wait for the day after tomorrow, and directly apply liquid lithium."

Sheng Xianfu nodded solemnly.

"Yes!"

As Lu Zhou predicted through calculations, when using liquid lithium with a relatively low density as the working liquid, its performance in sonoluminescence does exceed that of concentrated sulfuric acid and aqueous solutions. Especially when the deuterium and tritium mixed gas is passed in, the sound pressure acting on the surface of the bubble has increased significantly, reaching a maximum of 31.7 times the atmospheric pressure.

However, the liquid lithium working at 700 degrees Celsius was still too lively, and the experiment was more than several times more dangerous than the original use of concentrated sulfuric acid.

Especially in the third experiment, a small amount of oxygen was accidentally mixed into the deuterium and tritium mixed gas by the operator when electrolyzing heavy water and super heavy water, which caused a string of flames to burst into the container at the moment of gas introduction.

Fortunately, the amount of oxygen mixed in was not large, and several researchers in the laboratory responded in a timely manner, so they were rescued by the laboratory in no surprise. If it really melts through the working container, causing the high-temperature liquid lithium in the container to directly contact the air, let alone a laboratory, then I am afraid that the collapse of several load-bearing walls is light ...

In short, since then, the people in the entire Institute of Higher Education have looked differently at Sheng Xianfu ...

Time passed day by day, and soon came the day of the interview.

In the office of the School of Mathematics at Jinling University, Lu Zhou met the CTV interview team.

It is quite a coincidence that the reporter responsible for interviewing him only had a relationship with him only a few years ago.

"Hello, Professor Lu," with a professional smile on his face, He Ying, wearing a dark blue professional outfit, stretched out her right hand and gently held Lu Zhou, smiling with a nice voice, "We met again . "

She let go of her hand and Lu Zhou smiled and nodded.

"It's been a long time, Miss He ... let's start now?"

He Ying nodded with a smile: "Let's start now."

Knowing that Lu Zhou was usually busy with her research, she did not waste time on her greetings, and soon brought the interview to the topic.

After sitting down on the sofa, He Ying adjusted her sitting position, signaled the photographer next to her to start, and then continued to change her professional smile. She looked at Lu Zhou and said, "I am honored to have this opportunity to interview you Before the interview, I want to ask you a few questions on behalf of the audience in front of the TV. "

Lu Zhou smiled and said, "Ask, as long as I know and can say, I must know everything."

He Ying bent her corner and said, "Be assured, it is not a difficult problem."

As she said, she paused and continued to say, "We all know that the mass gap problem of the Young Mills equation is solved, and the unification of strong interactions and electromagnetic interactions will completely change the subject of the future physics. For people, this abstract statement can only make people feel confused. What do you think about the future of physics? "

Lu Zhou smiled and said, "Is it such a difficult problem at first?"

He Ying pouted with a smile and said, "It's difficult for others, but it shouldn't be difficult for you?"

"From the perspective of a scholar, about the future of theoretical physics ... I really don't really answer this very well, after all, no one knows whether new physics will be born tomorrow." Having said that, Lu Zhou thought for a while , Continued, "Looking at the long-term goal, what the theoretical physicist has been asking for in his life is naturally the unified theory. Now that strong interactions and electromagnetic interactions have successfully established a bridge, the rest is gravity. Of course, about This part of gravity is also very little known to us. Maybe after a century, we can only understand a little bit of fur. "

He Ying asked earnestly: "Is there any conclusion about the cause of gravity?"

Lu Zhou: "Of course, gravity is probably the most mysterious field in physics. Although we may feel it more intuitively than the other three basic forces, we have the least understanding of it. Even string theory and loop quantum Gravity explains its birth in two diametrically opposed ways, but knows that no one today can say for sure which of them is correct. "

He Ying continued to ask, "What about a more realistic goal?"

Leaning on the sofa, Lu Zhou thought for a while and said, "More realistically, or short-to-medium-term goals, naturally verify and explore the standard model. Although the standard model is great enough, through theoretical research and some Through experiments, we can always find something outside the standard model. "

Having said that, Lu Zhou paused for a moment and said in a joking tone: "Like m particles. Although I don't know what it looks like, but through mathematical methods, I can prove that it does exist. If anyone can find it, we You can add a new puzzle to the standard model building. "

He Ying: "This sounds very inspiring."

Lu Zhou smiled and said, "Of course, the exploration of the unknown is an exciting thing in itself."

He Ying: "However, despite this, theoretical physics is still a fairly distant existence for most of us. Could you please explain to us that the study of theoretical physics is important to our society and to us? Civilization ~ www.readwn.com ~ What impact can it have? "

Lu Zhou thought about this for a long time.

Just when He Ying began to wonder if she had asked any inconvenient questions, and she was about to let the photographer cut this out, Lu Zhou suddenly spoke.

"This is a very abstract proposition, and it is difficult for me to tell you what a theoretical physical discovery can produce that can be seen by ordinary people. Just like the Higgs particle, gravitational waves, and so on. All these years we have Most of the things found or obtained from the universe in which they live are useless to the average person. "

"Even with the m particles I mentioned earlier, even if we stand on the basis of the unified theory of strong electricity and the unified theory of weak electricity, we have further unified the four basic forces, and this universe will not change anything because of us. Maybe Taking the funds for exploring theoretical physics to improve our lives can indeed fill more people in a certain period of time and make our lives better. "

Having said that, Lu Zhou paused for a moment and continued to speak in a serious tone.

"However, if no one does what is deemed useless, we will have no future at all."
