On the morning of the 20th, Gong Qian sent a telegram from the Xu Mansion. Ye Qing had been discharged from the hospital a few days ago. At the same time, the computer technology of the Xu Mansion had made another breakthrough: with the Institute of Special Materials purifying a single crystal from quartz last October.
After using silicon and investing in the research of silicon wafer integrated circuits, the second-generation transistor was successfully developed at the beginning of last month. Just last night, the Type III computer with more powerful computing functions was completed under the guidance of Tesla.
This new type of computer uses silicon transistors, which are much cheaper than germanium transistors. It consists of 10,000 silicon transistors to form an eight-bit computing system. It has 32k (magnetic core) memory and is about the size of two computer desks stacked up in later generations.
size, and is equipped with peripheral interfaces to connect keyboards, electronic screens, speakers and card readers, and even a 7-inch super large floppy disk drive. Currently, researchers are studying graphical interfaces and mice, but this does not affect normal use.
.
Ten days ago, Tesla conducted another rocket launch from the Wulianfeng Rocket Base. This time, a satellite weighing 150 kilograms was sent into the sky. However, after returning from the experiment, Tesla seemed unhappy and put the rocket into the sky.
I locked myself in the office all day, and then concentrated all my energy on the development of computers. Yesterday I finally took out the latest prototype machine, which caused a sensation in the entire institute.
From last night to this morning, there was an endless stream of experts who came to test the machine. They praised the high performance of the computer and asked when the Type III computer could be put into mass production.
An Yi was very surprised after reading the telegram. Tesla is a strong guarantee for An Jiajun's technological leadership. Every invention and innovation of this all-round outstanding scientist has the potential to improve An Jiajun's technology by several degrees.
Steps, if something goes wrong with him, it will definitely be a big loss to Xu Mansion.
Under this situation, An Yi immediately instructed his staff to arrange a special plane back to Syria as soon as possible. In any case, he had to go see Tesla in person, ask what the problem was, and solve it immediately.
At the same time, Ye Qing was discharged from the hospital, and it was time to visit him both emotionally and rationally. Ye Zixin also brought a large group of women's troops to the Xu Mansion at the beginning of this month, and it was just in time to meet him.
At four o'clock in the afternoon, An Yi, accompanied by Gong Qian, appeared at the Rocket Research Center of Xufu Research Institute.
Ding Molan, deputy director of the center, was surprised and happy when she heard the notice from the staff. She hurried out of the office and saw An Yi and Gong Qian in the corridor. She first greeted Gong Qian politely, and then asked An Yi with a smile on her face: "
Why did you come back to Xufu? Have you visited Sister Chu'er in Xiyuan?"
An Yi nodded: "I just went home to see Chu'er and the children first, and then rushed over after Sister Qian met up. Anyway, the West Garden is not far from here. It only takes a few minutes to walk, which is very convenient. By the way, Mo
Lan, I came back this time because I heard that Uncle Nicholas was a little unhappy and wanted to help him solve his difficulties. Do you know what's wrong with him?"
Ding Molan felt sweet when she heard An Yi calling Tesla the same as herself, and then explained: "I know the inside story of this matter. After Uncle Nunla launched the rocket, after careful calculation, he found that the launch vehicle could not carry the load at all.
A large coil weighing tens of tons went up to the sky. I was very depressed and was thinking of other ways to solve this difficult problem.
.The reason why he actively participated in the development of computers was because he wanted to greatly improve the performance of computers to perform calculations on formulas and large amounts of data, and then verify an idea in his mind. If successful, he would immediately change his research direction.
, further in-depth research on rocket technology can only be carried out by our other researchers."
"oh?"
An Yi raised his eyebrows and asked with interest: "Besides rockets, is there any other way to send a large coil weighing dozens of tons into space?"
Ding Molan said solemnly: "That kind of device is called a mass projector. Before developing the rocket, Uncle Nicholas was actually more inclined to use that kind of device, but he had been studying rockets for many years and was reluctant to give up, so he gave it a try.
Whether it is possible to send the coil to the sky through rocket transport, but facts have proved that this method does not work, and the rocket can bear extremely heavy loads.
Due to limitations, the most optimistic estimate is that the load capacity cannot exceed ten tons, so we returned to the original idea. The mass projector needs to use an extra large coil to change the magnetism within a certain period of time to obtain the acceleration of the projectile.
Escape from the Earth's gravity. However, this involves a magnetic levitation acceleration system and a material called a superconductor, which is very tricky."
Facing An Yi's puzzled gaze, Ding Molan continued to explain: "The DC resistivity of the conductor suddenly disappears under certain conditions. This is called the zero resistance effect. Without resistance, no heat loss occurs when the current flows through the conductor.
, the current can flow through the
A strong current is formed in the wire, thereby generating a super strong magnetic field. Twenty-eight years ago, after the discovery of superconductivity and superconductors, Uncle Nikolai conducted special research on this. Sixteen years ago, Uncle Nikolai
It was discovered in experiments that when a metal is in a superconducting state
At this time, the magnetic induction intensity in this superconducting body is zero, but it squeezes out the magnetic field that originally existed in the body. Taking a single crystal tin ball as an example, when the tin ball transitions to the superconducting state, the magnetic field around the tin ball suddenly changes
, the magnetic field lines seem to be suddenly repelled to the tin
went outside the ball. In another experiment, a small but highly magnetic permanent magnet was placed in a shallow flat tin plate, and then the temperature was lowered to make the tin plate superconducting. The small magnet turned out to be superconducting.
Leaving the surface of the tin plate, it floats slowly and remains suspended.
"According to this principle, if the device used as a mass projector is made of superconducting materials, then only a small acceleration is needed to send the coil into space, and the transceiver device made of superconducting materials can transmit electrical energy in the form of electromagnetic waves.
It is not easy to cause consumption during the transmission process, and the efficiency of long-distance power transmission can be increased by at least 50%, which has many benefits!"
An Yi was still confused. Although he came from an era of knowledge explosion, these professional physics vocabulary still seemed a little too difficult for him.
Seeing An Yi's eyes widening, Ding Molan smiled, waved his hands and said: "Forget it, as the supreme commander of our Anjiajun military and political system, you don't need to understand these at all, as long as you know Uncle Nicholas
In addition, it is enough to have a way to solve the problem, and it is not just the set of solutions I just mentioned. Come on, I will bring it now
You go see Uncle Nicholas. He is now in the Materials Research Institute and assigns new tasks to the project team. In fact, I think even if you don’t come back, he will go to Xinjing City to find you. You assigned him last time
The funds are almost spent on rocket research. If we change our ways this time, we have to start over again, and the cost may be even more than rocket research!"
An Yi was stunned for a moment, then turned to Gong Qian: "Sister, can't you just make these decisions? Why bother Uncle Nicholas to find me?"
Gong Qian glared at him: "A large sum of fifty million US dollars is involved all at once, so it's better for you to make the decision. I don't dare to sign such a fund application report."
At this point, Gong Qian shook her head and smiled bitterly: "Mr. Nicholas's research project is really a money-devouring monster. If it hadn't been for the inexplicable epidemic of strange diseases in Australia this time, which caused the sales of anti-inflammatory drugs to double, and we were conducting research on the black market.
Speculate, double your profits, and earn a lot of profits, otherwise you will never be able to satisfy this big hole.
After all, the construction of Nanhua is now in the ascendant. The construction of the Institute of Nuclear Physics and supporting facilities, the construction of ships, weapons and ammunition, the payment of military salaries, government financial expenditures and investment in other research projects, etc., all require money. We all need money at once.
Too much, the monthly expenses are astronomical, it’s scary to think about it!”
When An Yi heard this, he smiled: "Sister Qian, you will get something if you put in the effort. Don't look at how much money we spend now, but in the future we will gain much more than we do now. Let's take rocket research and development as an example. Today we have
Rocket technology has been able to send satellites into space, which is at least twenty years ahead of other countries.
In the near future, we can launch into space communication satellites for radio, television, and telephone use, meteorological satellites for observing weather changes, navigation and positioning satellites for navigation and positioning of ground objects, and detection of the earth's land and ocean resources.
Satellites, and those used in the military
Reconnaissance satellites. Sister, think about it, just military reconnaissance satellites are enough to benefit us a lot. In a life-and-death war, we can monitor our opponents, but our opponents know nothing about us. How great is this?
What a terrible thing! Of course, these satellites involve
High-precision technology in all aspects requires long-term study and exploration, and it cannot be achieved overnight. But with the good foundation laid by Uncle Nicholas, we can organize people to overcome difficulties one by one. If there is something we don’t understand, we can still
If you ask him for advice, your future will be bright."
Ding Molan nodded in agreement: "Yes, that's what we are doing now. Today's international situation is chaotic, and a world war is about to break out. In order to ensure the survival of the country and the nation, and to defend the fruits of victory of our Anjia Army, the military use of satellites has become
Our priority research and development direction. In the first ten days of this month, the military reconnaissance satellite project has been officially established, and the project team is coordinated by me.
, the third group sent to Germany to study in 2029, Colonel Chen Mo, director of the Institute of Optics, who received a doctorate in physical optics from the University of Jena, served as my deputy. The members of the project team include students studying at the University of Rome in Italy, and just followed his mentor last month -
—Professor Fermi, a Jewish nuclear physicist, went to southern Yunnan to have Master Li Jiaxian and other experts and scholars in electronics and optics, which can be said to be an elite gathering.
“While the Materials Research Institute under the management of the Rocket Research Center developed single crystal silicon in October last year, researchers also discovered that silicon plus phosphorus constitutes a negative semiconductor, and silicon plus boron constitutes a positive semiconductor. The two are in contact.
After being stacked and exposed to light, electricity will be generated. The power generation efficiency is many times higher than that of the germanium semiconductor used in the 1980s, which was covered with an extremely thin layer of gold to form a semiconductor metal junction.
The photoelectric conversion efficiency of the first solar cell we produced was as high as 6.5%. By December, when the second-generation solar cell we developed was used as the power source for the first experimental satellite, the conversion rate was already as high as 12%. Last month
The small satellite launched on the 3rd is still orbiting the earth and operating in good condition, proving that the solar cells we developed can indeed provide a long-lasting source of power.
"After solving the power problem, what we have to solve is how to use satellites to obtain military intelligence. Our project team's initial opinion is to develop a photoelectric remote sensor, use it to take pictures of the ground, take pictures and perform synchronous radio transmission.
The receiving equipment on the ground restores the radio waves into pictures or video signals, interprets and identifies the nature of the target, and determines its geographical location.
Since the satellite is in an earth orbit at least 150 kilometers from the earth's surface, the ground resolution, time resolution, reconnaissance image width, and moving target indication capabilities of remote sensing equipment are the main directions of research and development. Once this long-distance photoelectric remote sensor is successfully developed
, it can be put into use. At that time, our powerful intelligence acquisition capabilities will ensure that we remain invincible in the war."
An Yi was amazed after listening to Ding Molan's introduction. Sure enough, these professional things can only be left to professionals. Now, just listening to them gives me a headache, let alone dealing with these things all day long.
Ding Molan's growth is amazing. She has solid professional knowledge. Due to being with Tesla for a long time, she has become an all-rounder who is proficient in various subjects. Her vision is far broader than that of ordinary people.
In addition, her organizational and coordination skills are top-notch, and she combines the overall advantages, and her general style is revealed.
It was Gong Qian who had a vicious vision and made decisive arrangements so that she would not miss such a close friend. With her helping him on the scientific and technological front, he could safely devote his mind to military and politics.
I don’t know how many lifetimes of cultivation this blessing is.
