On the morning of January 19th, the office of the director of the collision building.
Su Zhe sat at his desk and looked at the launch plan of the Xuanwu Project space probe on the 22nd.
In the Xuanwu Project, 3,000 domestic SS-defense system subsystems are the main body, supplemented by a small number of space detectors.
This launch plan requires a total of thirty-six detectors to be launched, carried by the same rocket, that is, thirty-six satellites with one arrow.
Of the thirty-six detectors, eighteen are deployed in low orbit and the other eighteen are deployed in high orbit.
The reason for launching these detectors is to expand the detection range of the SS-defense system.
Without these detectors, the effective detection range of the SS-defense system deployed on the ground is 10,000 kilometers from the ground. With the addition of these space detectors, the effective detection range can be extended to 300,000 kilometers. .
However, considering that these detectors were manufactured too hastily, their lifespan is very short, only half a year.
He looked at the parameters of the rockets carrying these detectors and was thinking about the heavy photon aerospace engine.
Rockets using chemical energy are too inefficient to transport power.
Take the thirty-six detectors to be launched this time as an example. When designing the detectors, not only the performance of the detectors, but also the mass and volume of the detectors must be considered. The result can only be compromised.
If there is a more powerful launch vehicle, then just consider the detector.
Then there is the experimental space power station built in space by the scientific research team of Academician Zhao Guoan of Northwest University of Electronic Science and Technology.
In order to build this space power station in synchronous orbit, three launches were carried out in just one month, and a total of thirty-six tons of materials were transported.
The transport capacity is only twelve tons at a time.
To be honest, this kind of transportation capacity cannot meet the current demand.
To change the status quo, heavy photon aerospace engines are a very good direction.
Just as he was thinking about it, he saw Fan Xiaoming walking into the office.
"What are you looking at! It's time." Fan Xiaoming reminded, "I heard that the principal has invited many domestic physics experts to participate in your graduation defense. You must be mentally prepared."
Su Zhe looked at the time and stood up, saying, "A lot? How many can there be?"
With that said, the two left the director's office.
"More than five hundred people!" Fan Xiaoming gestured with his hands.
"No! So many!" Su Zhe was very surprised.
"The principal is also a ruthless person. He actually invited so many elders." Fan Xiaoming said, "This is a graduation defense! It's just a speech."
"..."
The two were walking and talking, and five assistants, Zong Lanyue and Liu Fen, followed Su Zhe and Fan Xiaoming downstairs.
"Ma Ping! Did you go to the top floor of the west building of the library last night? All the physics bosses in the country came here just to participate in my boss's graduation defense." Bi Yuankui said softly with some pride.
"Go!" Ma Ping nodded excitedly, "To be honest, our big boss is the best in the physics world."
"..."
Su Zhe and his group of seven people got into the patrol car.
After a while, the patrol car stopped at the entrance of the library.
Instead of taking the internal elevator in the west building, the seven people took the spiral staircase between the east and west buildings to the top floor of the west building.
Su Zhe walked into Lecture Hall No. 1, and applause rang out.
Principal Xu Zhengping led him directly to the podium and introduced him excitedly.
Soon, Principal Xu Zhengping stepped down from the podium and gave it to Su Zhe.
Su Zhe looked at everyone in the lecture hall, greeted a few words and then went directly to the topic.
Graduation defense!
The first thing he explained was the paper "High Power Optical Energy Wired Transmission Technology".
At the beginning, he explained the principle of high-power optical energy wired transmission.
It sounds very simple. The principle of wired transmission of high-power optical energy is very simple. It is similar to the propagation of optical signals by optical fibers.
The difference is that the energy of optical signals propagated through optical fibers is very, very low.
Naturally, the two materials are also different.
In the whole process, the first thing to do is to convert other different forms of energy, the most typical of which is electrical energy, into light energy at point a, and then send the light energy to point b through a special optical cable like optical fiber, and then transfer the light energy to point b. converted into electrical energy.
During the transmission process, the energy consumption is far less than the consumption of electrical energy transmission, and the transmission of light energy only requires one optical cable.
When necessary, optical cables that transmit light energy can not only transmit energy, but also information.
Su Zhe finished explaining the principle of wired transmission of high-power light energy, and then explained the carrier of high-power light energy, optical cable.
From materials to structures, and then to manufacturing processes.
After talking about this, we talked about the electro-optical conversion device and the photoelectric conversion device at both ends of the optical cable.
Just like optical cables, materials, structures, and manufacturing processes are discussed.
However, what Su Zhe said are general and there is no specific introduction.
In his opinion, it would be good to give a general introduction, but it would be foolish to be specific.
After introducing the paper "High Power Optical Energy Wired Transmission Technology", there was warm applause in the lecture hall.
Then came the question and answer session.
The elders were very active and asked one question after another.
Su Zhe was also very straightforward and answered everyone who could.
After the question and answer session, Su Zhe made a brief summary, and then the undergraduate graduation defense ended.
The time has also come to twelve noon.
After lunch, Su Zhe went back to the apartment to rest, but these elders did not and came to Lecture Hall No. 1 to discuss.
The elders attach great importance to the paper "High Power Optical Energy Wired Transmission Technology" because everyone knows the importance of this paper.
The time came to two o'clock in the afternoon.
Su Zhe began to explain his master's thesis "Microscopic Principles of Mutual Conversion of Electromagnetic Waves."
The paper "Microscopic Principles of Mutual Conversion of Electromagnetic Waves" was written based on the zgz-atomic vibration model and material spectrum.
It deeply explores the principle of mutual conversion of electromagnetic waves of different wavelengths.
Relatively speaking, the paper "Microscopic Principles of Mutual Conversion of Electromagnetic Waves" is the most important of the three papers for this undergraduate, master's and doctoral degree.
Whether it is the paper "High Power Optical Energy Wired Transmission Technology" or the paper "Theoretical Basis of Heavy Photon Aerospace Engine", they will involve the mutual conversion of electromagnetic waves.
Su Zhe explained this paper for three hours, plus an hour for Q&A and summary. The paper ended at six o'clock in the evening.
After it was over, Su Zhe and everyone went to the cafeteria to have dinner, and started again at seven o'clock.
The last thing Su Zhe explained was the paper "Theoretical Basis of Heavy Photon Aerospace Engine".
Compared with the concept of a heavy photon aerospace engine mentioned in the paper "On the Manipulation of Atoms by Electromagnetic Waves", the paper "Theoretical Basis of a Heavy Photon Aerospace Engine" elaborates on the principle and structure of a heavy photon aerospace engine.
When Su Zhe explained the paper "Theoretical Basis of Heavy Photon Aerospace Engine", all the elders listened extremely seriously.
As we all know, the heavy photon aerospace engine is epoch-making. Once realized, it will no longer be a dream for mankind to fully enter space.
Speaking of which, the principle of heavy photon aerospace engines is not too difficult.
The core principle is the zgz-atomic vibration model. Atoms in a specific state release heavy photons after absorbing electromagnetic waves of specific wavelengths.
In the process of releasing heavy photons, the atoms gain kinetic energy.
For the heavy photon aerospace engine, Su Zhe gave two sets of design plans.
One is to convert electrical energy into light energy, and then convert the light energy into electromagnetic waves of specific wavelengths to attack atoms in specific states, thereby producing heavy photons.
The second is to use light energy directly, eliminating the step of converting electrical energy into light energy.
By 11 o'clock in the evening, the third thesis defense was over.
Principal Xu Zhengping also symbolically solicited the opinions of all the elders present. Finally, all the elders unanimously agreed that Su Zhe passed the defense of his three thesis, master's degree and doctoral degree.
Just as Su Zhe was about to step off the podium and go back to sleep, Assistant Principal Han Guoli immediately invited Fan Xiaoming, who was sitting below the podium, to come up to the podium.
Principal Xu Zhengping issued letters of appointment to Su Zhe and Fan Xiaoming in the presence of all the elders.
After the end, Su Zhe and Fan Xiaoming left Lecture Hall No. 1, only a few dozen meters away, when Principal Xu Zhengping chased after them.
"Principal! What's the matter with you chasing me?" Su Zhe asked with some confusion, holding the appointment letter in his hand.
Fan Xiaoming also looked at Xu Zhengping curiously.
"The thing is like this. Domestic physicists finally got together. Many people proposed to hold a symposium tomorrow. Let's sit together and talk about the future and direction of physics." Xu Zhengping said and looked at Su Zhe and Fan Xiaoming.
"Tomorrow!" Su Zhe said hesitantly.
"What? What do you want tomorrow?" Xu Zhengping asked with a smile.
"We are going to Northwest University of Electronic Science and Technology tomorrow to attend the completion ceremony of the Zhuguang Engineering Experiment Station." Fan Xiaoming explained.
"That's it! I thought it was something!" Xu Zhengping said with a smile, "Let's put it this way! Many of the physicists sitting in Lecture Hall 1 have received invitations, and so have I. There is also the launch of the Xuanwu Project space probe on the 22nd.”
"Then how did the principal arrange it?" Fan Xiaoming asked with a smile.
"This is what I think. Northwest University of Electronic Science and Technology is only more than 200 kilometers away from our school, and it is only 100 kilometers away from the satellite launch center. The school will arrange a bus to attend the Northwest University of Electronic Science and Technology Chasing the Light on the 21st. The completion ceremony of the engineering experiment station, then participating in the launch of the Xuanwu Project space probe on the 22nd, and finally a group of people from our school went directly to the Tamu Desert." Xu Zhengping said with a smile.
"This is good! This is good!"
Su Zhe and Fan Xiaoming smiled and nodded.
After saying a few more words, Xu Zhengping returned to Lecture Hall No. 1. Su Zhe and Fan Xiaoming left the top floor of the west building and came to the spiral staircase.
"This is really good. Let's treat it as a trip. Anyway, the three places are not far away." Fan Xiaoming said as he went down the stairs.
"Yes!" Su Zhe smiled and nodded.
…
The next day, the auditorium.
When Su Zhe and Fan Xiaoming came to the auditorium, it was packed with people!
The small auditorium was packed with people.
Except for those physics seniors, the others are mainly teachers and students from the School of Physics.
After receiving the news, these teachers and students came to the auditorium early to occupy their seats.
This symposium was hosted by Academician Wang Xiuqi, Dean of the School of Physics.
At the beginning, everyone was talking about the cultivation of physics talents.
When talking about this, a group of elders highly praised the Four Books Club, saying that the Four Books Club not only streamlined physics textbooks, but also organized and summarized physics-related knowledge.
This greatly facilitates the learning of teachers and students.
The students in Physics Class 1 at the scene were very grateful for this kind of praise.
Then Yong talked about academic journals in physics.
At this time, an elder mentioned that students from the School of Physics of Lingzhou University of Science and Technology had forcefully promoted the "Journal of Science" run by the Academy of Sciences.
Principal Xu Zhengping explained with a smile that this is not just the School of Physics, but the entire freshman class of Lingzhou University of Science and Technology.
He also said that this year's freshmen students are more confident than the previous students, which made the freshmen at the scene very happy.
When talking about this topic, the physics elders of the Academy of Sciences were very happy.
In the past, few people at home and abroad submitted high-quality papers to the "Journal of Science" of the Academy of Sciences. In the eyes of those people, English is good, and foreign papers are good.
But the first-year students of Lingzhou University of Science and Technology did not do this. The papers were written in Chinese and submitted to "Journal of Science". The most important thing is that these papers are of high quality.
Slowly, the trend began to change, and more and more people submitted articles to the Journal of Science.
Everyone was talking about the big scientific device.
From the synchrotron radiation facilities being built everywhere in the country, we talked about the hadron collider.
At this time, many people were lamenting the delay in the establishment of the Large Hadron Collider project led by the School of Physics of Lingzhou University of Technology.
At the same time, everyone was thankful for the Super Hadron Collider complex project led by Jiutian Research Center.
In less than half a year, Jiutian Research Center already has the money and people it needs.
In the past, a nationwide effort was made to build a Large Hadron Collider, but projects failed time and time again due to issues with scientific research funding.
But now, Jiutian Research Center alone is about to build a more advanced super hadron collider complex.
When talking about the Large Hadron Collider, Fan Xiaoming began to introduce the Super Hadron Collider complex.
From the design of the Super Hadron Collider complex to the performance of the Super Hadron Collider complex.
While talking, the eyes of all the physicists in the auditorium were red.
According to Fan Xiaoming's description, the Super Hadron Collider complex will be the most powerful collider in the world.
It is no exaggeration to say that once the Super Hadron Collider complex is completed, it will be able to conduct all currently known high-energy particle experiments.
At the end of his speech, Fan Xiaoming talked about building a more powerful hadron collider in space.
Hearing this, the physics experts became even more excited.
…
In the afternoon, everyone began to talk about the development direction of physics.
Nothing more than the study of the greater and the smaller.
Reaching the structure of the universe, down to elementary particles.
At 4:30 p.m., the symposium ended.
After dinner, a group of physics seniors packed up and took the bus to Northwest University of Electronic Science and Technology, two hundred kilometers away.
The whole journey was at high speed, and it was 8:30 in the evening when Su Zhe and a group of physics experts arrived at Northwest University of Electronic Science and Technology.
