What should I do if I am captured by aliens one day?

Then go with the aliens and see the unexpected world of Earth.

There's no way, just think it's an interstellar trip, isn't it great, if there are really aliens, I hope he will take me away, just in time for me to go out and see the planet.

In that case, it's almost impossible, unless you have a special ability, so that you can stop the aliens from taking you.

Whimsical, a little imaginative, and if you really catch it, you will follow them.

Then you are the first in the world.

The production process of electricity is extremely complex, with multiple processes such as power generation, transmission, distribution, and consumption. Among them, power generation refers to the place where electric energy is produced, such as: thermal power units, hydropower units, etc.; Transmission refers to the operation of using high-voltage lines to complete power transmission; Substation refers to the use of high-voltage substation to convert high-voltage voltage, ultra-high-voltage voltage and other electrical energy into low-voltage electrical energy; Distribution is the final step, which reduces the voltage and delivers the electricity to the consumer.

The power transmission and transformation project of the power system attaches importance to the two steps of transmission and transformation. With the rapid increase in China's electricity demand, there is an urgent need for power system transmission and transformation projects to undertake the transmission and transmission of the power system. A number of power transmission and transformation projects together constitute the main frame of China's power grid.

At this stage, China's power transmission and transformation projects generally have multiple voltage levels such as 110kv, 220kv, 330kv, 500kv, etc., of which 220kv is used more frequently in China; 330kV is commonly found in China's northwest power grid; The 500kV level is the highest, and the requirements for cost, capacity, and process are higher and more advanced. At present, China attaches great importance to the construction of 500kV power grid, which is the backbone of China's power grid. Power transmission and transformation engineering is an important engineering project in the construction of the main grid of the power grid, including transmission line engineering and substation engineering, which requires high costs, extremely complex engineering construction, and high construction technical requirements.

Power transmission and transformation projects generally include electrical installation, communication and automation, civil engineering, electrical equipment commissioning, system start-up and commissioning, etc. Among them, electrical installation includes the installation of primary equipment such as high-voltage equipment, and also includes the wiring and installation of secondary equipment such as protection and control systems; Communication and automation refers to communication engineering and substation automation; Civil engineering covers equipment foundation, building engineering, four-way and one-level, frame foundation, etc.; The commissioning of electrical equipment is to test and adjust the installed primary equipment and secondary equipment; System start-up and commissioning refers to the start-up and commissioning of the operation of transmission lines and substations after the construction of power transmission and transformation projects. The status quo of power system power transmission and transformation project management does not pay attention to the coordination of the project scheduleThe power system power transmission and transformation project is very different from other projects, and the requirements of the power system power transmission and transformation project are higher, and the construction progress is required to be carried out in strict accordance with the specified requirements to ensure that the project construction is completed on time.

At this stage, most of China's power enterprises do not pay attention to the management and coordination of the progress of power transmission and transformation projects, which seriously affects the quality of the project, which not only reduces the ability of construction personnel and engineers to control the progress of the project, but also has a great impact on the efficiency and quality of the project. A small number of power transmission and transformation projects only pay attention to the progress of the project, and lack the supervision of the project quality, resulting in the problem of urban power shortage.

Discharge cooling is another type of convection cooling. Unlike regenerative cooling, the coolant used for exhaust cooling absorbs heat to the thrust chamber and is discharged out of the combustion chamber instead of entering the combustion chamber to participate in combustion. Direct drain coolant reduces the thrust chamber specific impulse, so the coolant flow for drain cooling needs to be minimized while only using drain cooling at the outlet section of the nozzle that is relatively less heated.

There is also radiative cooling, in which the heat flow is transferred from the combustion products to the thrust chamber, and then the heat is radiated by the thrust chamber wall to the surrounding space. Radiative cooling is characterized by simplicity and small structural mass. It is mainly used in the extension section of large nozzles and the thrust chamber of small thrust engines using high-temperature resistant materials.

When cooling in the thrust chamber of the tissue, a relatively low temperature liquid or gas protective layer is established on the surface of the thrust chamber wall to reduce the heat flow to the thrust chamber wall, reduce the wall temperature, and achieve cooling. Internal cooling is mainly divided into three methods: internal cooling (shield cooling), membrane cooling and diaphoretic cooling of head tissues. After the internal cooling measures are adopted in the thrust chamber, the mixing ratio near the wall of the combustion chamber is different from the optimal mixing ratio in the central area (in most cases, the near-wall layer rich in fuel is used) due to the need to reduce the temperature of the protective layer, resulting in the uneven distribution of the mixing ratio along the cross-section of the combustion chamber, so that the combustion efficiency is reduced to a certain extent.

Membrane cooling is similar to shield cooling in that it cools the thrust chamber wall by establishing a uniform and stable coolant film or air film protective layer near the inner wall surface, except that the coolant used to establish the protective layer is not injected by the injector, but is supplied through a special cooling belt. The cooling band is generally arranged in a cross-section of the combustion chamber or the convergence section of the nozzle. There can be several cooling bands along the length of the combustion chamber.

In order to improve the stability of the membrane, the coolant often flows through the gaps or small holes in the cooling belts, and when sweating is used, the thrust chamber wall or part of the inner wall is made of porous material with a pore diameter of tens of microns. Porous materials are usually sintered with metal powders or pressed with metal mesh. In this case, the number of pores per unit area is increased by making the micropores in the material as evenly distributed as possible.

The liquid coolant penetrates into the inner wall, creating a protective film that reduces the density of the heat transferred to the wall. When the flow rate of liquid coolant used for sweat cooling is above a certain threshold, a liquid film is formed near the wall of the thrust chamber. When the coolant flow rate is below the critical flow, the inner wall temperature will be higher than the coolant boiling point at the current pressure, and some or all of the coolant will evaporate, forming an air film.

In addition to the above thermal protection, there are other thermal protection methods such as: ablation cooling, thermal insulation cooling, hot melt cooling and composite protection of chamber walls. 3. Thermal protection scheme of high enthalpy gas generator Based on the above methods and the actual situation, the thermal protection method of high enthalpy gas generator is obtained.

The combustion chamber of a high-enthalpy gas generator differs from that of a liquid rocket engine, eliminating the front thrust chamber part, making its structure simpler and more effective. Then, the thermal protection involved is the thermal protection part of the combustion chamber wall. As the fuel enters the combustion chamber, it quickly decomposes and releases large quantities.

<> in the vast and infinite universe, aliens and advanced life definitely exist. But at the moment there are no real signs of aliens. Some of the alien news reported on ** is false news that cannot be verified.

As for the mystery of the universe and the mystery of extraterrestrial life, human beings need to continue to explore, research and discover in the future.

Contact the National Aeronautics and Space Administration (NASA) and they will conduct a systematic and detailed full-body examination for you, and possibly hire you as the lead advisor to the Extraterrestrial Abduction Investigation Committee to spread alien culture throughout the universe.

I haven't seen an alien, so when I do, I'll study its weaknesses and help you figure it out.

What's wrong with you?

Hello, would you be worried that you yourself will be captured by the satellites? Aliens may exist (except in the solar system). However, the huge distance of space has become an insurmountable obstacle to the interconnection of intelligent beings, so even if there are aliens, it is difficult for us to find out, let alone know that they live in**.

You can imagine that even a Guangling attack with a speed of 300,000 kilometers per second would have to run for years, decades, hundreds, tens of millions of years, or even longer! What an unimaginably long distance! Therefore, it is simply impossible for the so-called aliens to visit or invade the earth!

Constrained by the laws of physics, it is hard for me to believe that intelligent beings can build spacecraft that can fly at the speed of light, which is all science fantasy, how can it be so easy? Therefore, it is not credible. It can be said that so far, Chan Meng has not had any credible evidence that aliens have visited our earth.

So I think your worries are completely unwarranted haha!

Impact 1: Aliens will invade Earth.

Scientists represented by Stephen Hawking believe that the only impact of earthlings coming into contact with aliens is that aliens will plunder all the resources on the earth, and then find ways to enslave human beings, which is the same as Columbus's discovery of the New World in the Americas, which only brings disaster and suffering, and no benefit at all. So, this is the last thing most people want to happen.

Influence 2: Aliens and humans barely intersect.

Slightly better than an alien invasion of Earth is that aliens don't have much to do with humans and may just treat us like animals. The main reason is that the civilization level of aliens is too much higher than ours, so in their eyes, humans are just animals in the third dimension, and they have also seen humans in the fourth dimension, and humans in the fifth dimension have long been accustomed to it, in short, they are much smarter than humans in the third dimension.

Impact 3: Aliens help humans improve their technological civilization.

In fact, the reason why human beings are trying to find aliens is not to let aliens invade the earth, not to let aliens treat humans as animals, but to be able to learn more advanced science and technology from alien civilizations and improve the overall level of human civilization. Some scientists believe that we should not think of aliens as villains who do all kinds of evil, but that they may be very friendly and willing to help humanity develop.
