Chapter 1499 changed course

On the morning of the 20th, Gong Qian sent a telegram in Syria that Ye Qing had been discharged from the hospital a few days ago, and at the same time, Syria's computer technology had made another breakthrough: With the special materials research institute purifying monocrystalline silicon from quartz in October last year and putting into the research of silicon wafer integrated circuits, the second-generation transistor was successfully developed at the beginning of last month, and just last evening, the type III computer with more powerful computing functions was completed under the guidance of Tesla. Pen & Fun & Pavilion www.biquge.info

This new type of computer uses silicon transistors, which are much cheaper than germanium transistors, and consists of 10,000 silicon transistors to form an eight-bit computing system, with 32K (magnetic core) memory, which is about the size of two computer desks stacked on top of each other in later generations, and is equipped with peripheral interfaces to connect keyboards, electronic screens, speakers, card readers, and even a 7-inch super-large floppy disk machine. Currently, researchers are working on graphical interfaces and mice, but they do not affect normal use.

Ten days ago, Tesla carried out another rocket launch at the Wulianfeng rocket base, this time sending a 150-kilogram satellite into the sky, but after returning from the experiment, Tesla seemed sullen and locked himself in his office all day, and then concentrated all his energy and devoted himself to the development of the computer, and finally took out the latest sample machine yesterday, causing a sensation in the entire research institute.

From last night to this morning, there was an endless stream of experts who came to test the machine, full of praise for the high performance of the computer, and asked when the Type III computer would be ready for large-scale production.

An Yi was very surprised after reading the telegram, Tesla is related to A Jiajun's leading science and technology A strong guarantee, this all-round outstanding scientist, every invention and innovation, it is possible to raise An Jiajun's mastery of science and technology up a few steps, if he has any problems, it will definitely be a big loss for Syria.

In this case, An Yi immediately instructed the staff to arrange a special plane back to Syria as soon as possible, and in any case, he had to meet Tesla in person, ask what was wrong, and solve it immediately.

At the same time, Ye Qing was discharged from the hospital, it is reasonable to pay a visit, and Ye Zixin also brought a large number of women's troops to Syria at the beginning of this month, and they happened to meet together.

At four o'clock in the afternoon, An Yi, accompanied by Gong Qian, appeared at the Rocket Research Center of the Syrian Academy of Sciences.

Ding Molan, deputy director of the center, was surprised and delighted when she heard the notice from the staff, hurriedly walked out of the office, saw An Yi and Gong Qian in the corridor, first greeted Gong Qian politely, and then asked An Yi with a smile: "Why did you come back to Xufu?" Have you been to the West Garden to see Sister Chu'er? ”

An Yi nodded: "I just went home to see Chu'er and the children first, and waited until Sister Qian met before rushing over." Anyway, the West Park is not far from here, just a few minutes walk away, which is very convenient. By the way, Mo Lan, I came back this time because I heard that Uncle Nikolai was a little unhappy and asked to help him solve his difficulties, do you know what happened to him? ”

Ding Molan heard An Yi call Tesla the same as herself, and her heart was sweet, and then explained: "I know the inside story of this matter. After the nun Uncle La launched the rocket, after careful calculations, he found that the launch vehicle could not carry a large coil weighing dozens of tons to the sky, and he was depressed and was thinking of other ways to solve this thorny problem. The reason why he took the initiative to join in the development of the computer was also to greatly improve the performance of the computer to perform the calculation of formulas and a large amount of data, and then verify an idea in his heart. If it succeeds, he will immediately change the direction of his research, and 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: "In addition to rockets, what other way can send a large coil weighing dozens of tons into space?" ”

Ding Molan said solemnly: "That device is called a mass projector. Before the development of rockets, in fact, Uncle Nikolai preferred to use that kind of device, but he studied rockets for many years and was reluctant to give up, so he tried to see if he could send the coil into the sky by rocket delivery, but it turned out that this path did not work, the rocket load was extremely limited, and the most optimistic estimate of the load capacity could not exceed ten tons, so he returned to the original idea. Mass projectors require a very large coil that changes the magnetism for a certain period of time to obtain the acceleration of the projectile in order to break free from the gravitational pull of the Earth. However, this involves magnetic levitation acceleration systems and a material called superconductors, which is very tricky. ”

Facing An Yi's bewildered gaze, Ding Molan continued to explain: "The DC resistivity of the conductor suddenly disappears under certain conditions, which is called the zero resistance effect, and without resistance, there is no heat loss when the current flows through the conductor, and the current can form a strong current in the wire without resistance, thus generating a super strong magnetic field. Sixteen years ago, Uncle Nikolai found in experiments that when the metal is in a superconducting state, the magnetic induction intensity in the superconductor is zero, but the magnetic field originally existing in the body is squeezed out. In the case of a single crystal solder ball, when the solder ball transitions to a superconducting state, the magnetic field around the solder ball suddenly changes, and the magnetic field lines seem to be repelled out of the solder ball all at once. In another experiment, a small but very magnetic permanent magnet was placed in a shallow flat tin plate, and then the temperature was lowered to make the tin plate appear superconductive, and the small magnet actually left the surface of the tin plate and slowly floated up, levitating without moving.

"According to this principle, if the device used as a mass projector is made of superconducting materials, it only needs a small acceleration to send the coil into space, and the transceiver device made of superconductor materials is not easy to consume electrical energy in the process of electromagnetic wave transmission, and the efficiency of long-distance power transmission can be increased by at least 50%, which has many benefits!"

An Yi still heard it in a fog, although he came from the era of the big explosion of knowledge, these professional physics vocabulary still seemed a little too difficult for him.

Seeing An Yi's eyes widening and widening, Ding Molan smiled and waved his hand: "Forget it, as the supreme commander of our Anjia Army's military and political system, you don't need to understand these at all, as long as you know that Uncle Nikolai has another way to solve the problem, and it's not just the set of plans I just said." Come, I'll take you right now to meet Uncle Nikolai, who is now in the Materials Research Institute, giving a new assignment to the project team. Actually, I think even if you don't come back, he will go to Xinjing City to find you, the last time you allocated funds, the research of rockets was almost spent, this time change course, and have to start again, the cost may be more than rocket research! ”

An Yi was slightly stunned and turned to Gong Qian: "Sister, don't you just make a decision?" Why bother Uncle Nikolai to find me? ”

Gong Qian glared at him: "It involves a large amount of 50 million US dollars all of a sudden, it is better for you to make the decision, I don't dare to sign such a fund application report." ”

Speaking of this, Gong Qian shook her head and smiled bitterly: "Mr. Nikolai's research project is really a monster that eats up funds, if it weren't for the inexplicable epidemic of strange diseases in Australia this time, which led to the doubling of sales of anti-inflammatory drugs, plus we speculated on the black market, multiplied the profits, and earned a lot of profits, otherwise we would not be able to meet 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 and weapons and ammunition, the payment of military salaries, government financial expenditures and other research project investment, etc., all aspects need money. ”

When An Yi heard this, he smiled: "Sister Qian, there is a harvest if you pay, don't look at how much money is spent now, in the future, our harvest will be much more than now." Take rocket research and development as an example, now our rocket technology has been able to send satellites into space, which is at least 20 years ahead of other countries. In the near future, we will be able to launch into space communications satellites for radio, television, and telephone use, meteorological satellites for observing weather changes, navigation and positioning satellites for navigation and positioning of ground objects, exploration satellites for detecting the earth's land and sea resources, and reconnaissance satellites for military purposes. Sister, think about it, just a reconnaissance satellite for military purposes is enough to benefit us immensely, in a war to the death, we can monitor the opponent, but the opponent knows nothing about us, what a terrible thing! Of course, these satellites involve all aspects of high-precision technology, which requires a long period of study and exploration, and is not achieved overnight, but with the good foundation laid by Uncle Nikolai, we can organize people to overcome difficulties one by one. ”

Ding Molan nodded in agreement: "That's right, that's what we're doing now." In order to ensure the survival of the country and the nation, and to defend the fruits of the victory of our Anjia Army, the military use of satellites has become our priority research and development direction. Colonel Chen Mo, director of the Institute of Optics, who was sent to Germany in 29 to study and obtained a doctorate degree in physical optics from the University of Jena, served as my deputy, and the project team included Master Li Jiaxian, who studied at the University of Rome in Italy and just went to southern Yunnan with his mentor, Professor Fermi, a Jewish nuclear physicist, and other experts and scholars in electronics and optics.

"The materials research institute under the management of the rocket research center, at the same time as the research of monocrystalline silicon in October last year, the researchers also found that silicon plus phosphorus constitutes a negative semiconductor, silicon plus boron constitutes a positive semiconductor, and the two will generate electricity by irradiating light after touching the stack, and the power generation efficiency is many times higher than that of the germanium semiconductor used in the eighties of the last century to form a semiconductor metal junction covered with a very thin gold layer, and the photoelectric conversion efficiency of the first solar cell we made was as high as 6.5%, and in DecemberThe second-generation solar cells we developed were used as a power source for the first experimental satellite, with a conversion rate of up to 12%, and the small satellite launched on the 3rd of last month is still orbiting the earth and is still running well, proving that the solar cells we developed can indeed provide a long-lasting power source.

"After solving the power problem, what we need to solve is how to use satellites to obtain military intelligence. The preliminary opinion of our project team is to develop a photoelectric remote sensor, which can be used to take pictures and photographs of the ground and carry out synchronous radio transmission, and the receiving equipment on the ground will restore the radio waves into pictures or video signals, interpret and identify the nature of the target, and determine its geographical location. Since the satellite is in the earth's orbit at least 150 kilometers from the earth's surface, the ground resolution, time resolution, reconnaissance image width, and moving target indication capability of remote sensing equipment are the main directions of research and development. ”

An Yi listened to Ding Molan's introduction and was amazed. Sure enough, these professional things can only be handed over to professionals to solve, and now just listening to them makes me feel a headache, let alone dealing with these things all day long.

Ding Molan's growth is amazing, she has solid professional knowledge, because of the long-term follow-up of Tesla, under the influence of her ears and eyes, she has also become a proficient all-rounder in various disciplines, her vision is far broader than the average person, plus her organization and overall planning ability is first-class, comprehensive general advantages, the general demeanor looms.

It is still Gong Qian's vicious vision, and she decisively made arrangements, so that she and such a confidante did not miss out, and she helped her on the scientific and technological front, so that she could rest assured that she could use her mind on military and politics, I don't know how many lifetimes of blessings have been cultivated.
