Sistema Dragón de Todos los Cielos - Capítulo 2953

Superconductivity is a state in which the resistance of the guide body is zero at a certain temperature. En 1911, the Dutch physicist H-Camolin-Onnes discovered that mercury suddenly entered a new state when the temperature dropped to around 4.2K. The resistance is so small that it is practically impossible to detect it. He called this new state of mercury a superconducting state, and later discovered that many other metals also have superconductivity.

En 1933, Meissner and Olsenfeld of the Netherlands jointly discovered another extremely important property of superconductors. When the metal is in a superconducting state, the magnetic induction intensity in the superconductor is zero, but it squeezes out the magnetic field originally existing in the body. Salir; experiments on the single crystal solder ball found that when the solder ball transitions to the superconducting state, the magnetic field around the solder ball suddenly changes, and the lines of magnetic force seem to be repelled out of the superconductor all at once. People call this phenomenon “Meisner effect”.

Luego, people did such an experiment: put a small but very magnetic permanent magnet in a flat tin plate, and then lower the temperature to make the tin plate appear superconductivity. En este momento, puedes ver , The small magnet actually left the surface of the tin plate, floating slowly, floating still.

Superconducting materials and superconducting technology have broad application prospects. The Meissner effect in superconductivity allows people to use this principle to make superconducting trains and superconducting ships. Because these vehicles will operate in a suspended frictionless state, This will greatly improve their speed and quietness, and effectively reduce mechanical wear.

The use of superconducting levitation can produce wear-free bearings, and the bearing speed can be increased to more than 100,000 revolutions per minute. The zero resistance characteristics of superconducting materials can be used for power transmission and the manufacture of large magnets. UHV power transmission will cause great loss. Superconductors can minimize losses.

Sin embargo, because superconductors with higher critical temperatures have not yet entered the practical stage, which limits the application of various technologies, if what is said in this email is true, it means that human technology has changed dramatically.

In factories, people can process parts with tools with a speed of more than 100,000, and there is no need to worry about bearing wear; outdoors, people can ride on superconducting trains at speeds that can even exceed airplanes; in cities, people can drive suspended cars, No longer have to worry about traffic jams, you can even park the car outside the balcony, so that the problem of difficult parking is solved.

Reducing the consumption in the transmission process is also of great significance. Although my country’s UHV transmission technology dominates the world, there is still consumption in the transmission process, and it also affects the transmission distance of power stations. If superconducting wires are used, the country Only a few large power stations are needed to meet all needs.

En el futuro, thermal power plants can be cancelled directly, and photovoltaic power plants seem to be able to withdraw from the stage of history. Although photovoltaic power generation is a relatively clean energy source, it still causes certain pollution. As for hydropower plants, it can also be greatly reduced, leaving only the flood control of the dam. Características.

The large-capacity battery means that the era of electric cars will truly come. The current fast charging technology can be filled with 80% of the electricity in 34 minutos, which is equivalent to about 300 kilometers of cruising range, but a full-fuel car can travel 300 kilómetros. Gasolina, which only takes a short while, still has a huge advantage over electric cars.

Sin embargo, according to the information provided by Shen Long, this new type of battery can run a car for 500 kilometers with a single storage of electricity, and it is smaller, only less than one-third of the current car battery, so that a car can at least With three batteries installed, it has a battery life of 1,500 kilómetros.

And the charging speed is also very fast. A battery can be fully charged in less than one minute, and it takes only two minutes to fully charge three batteries. This is faster than a car filling up a tank of fuel, and the output power is no more than gasoline. , Diesel is poor, and there is no need to worry about fuel explosion in a car accident.

Academician Lu looked through the list of materials for the battery production process and found that the process is not complicated, and there are no particularly expensive products among the materials. The battery produced in this way will not cost more than the car battery on the market today.

Al mismo tiempo, according to the product description, this battery can also work in a variety of harsh environments such as drought, humedad, y frío, and even has a wider range of applications than fuel vehicles. At least electric vehicles do not have to worry about stalling in areas with thin air.

It is foreseeable that once this kind of battery can be commercialized, the history of fuel vehicles should be over. This performance is a full blow to the existence of ordinary cars?

Después de leerlo, Academician Lu immediately reported the contents of the email, which immediately attracted the attention of the superior department. “Ja ja, but good things have continued recently. Primero, a major breakthrough has been made in controllable nuclear fusion. Here comes such a good thing! This should be a good celebration!”

“sí, if this kind of battery can really be manufactured, then the good day for our domestic cars is finally coming!” Although the sales of domestic cars have been rising year after year, joint venture brands account for a large number of foreign technologies. The localization of automobile production technology is much slower than the localization of high-speed rail.

These leaders are very dissatisfied with this, but there is no good way for the moment. Ahora, with this technology, that is a good thing. The domestically-produced car can finally turn over.

“Superconducting technology is equally important. It has a very wide range of applications in various fields such as industry, militar, and civilian use. If this material can be made~www.mtlnovel.com~ we can extend Europe and the United States far Behind you! Start a new technological revolution. “These achievements are of great strategic significance.

“Immediately organize a skilled, loyal and reliable team to study these two materials, and strive to produce them as soon as possible.” After so many things before, they now have full trust in Shen Long’s mail, and now controllable nuclear fusion has been realized. These information must also be true.

“Oye, I really want to thank that person back then, but it’s a pity that they have been reluctant to show up!” Someone sighed regretfully, “I don’t know how many good things he still hasn’t brought out.”

“We can’t be too greedy. These are all unexpected joys. It is already very happy to have such a harvest. We can’t make people angry because of greed. además, según la situación actual, people are not keeping well. I don’t want to take things out, maybe it’s waiting for us to slowly digest these materials? No, new materials will come as soon as Academician Lu has produced results.”

“De este modo, if we come up with new results, there is still possibility to send information?” Someone heard this, their eyes suddenly brightened, new results, I have them here.
