Auroras are caused by high-speed charged particles emitted by the sun that are attracted by the eart

It can be said that aurora is the effect of magnetism on electricity.

Auroras are mainly caused by electrons in the flow of charged particles entering the Earth's magnetic field. The color and intensity of the auroras also depend on the energy and number of falling particles.

The sun, which is 150 million kilometers away from the earth, radiates material points to the earth almost continuously. There is a magnetic field covering the earth 50,000 to 65,000 kilometers away from the earth. When the sun's particles are blocked by this magnetic field, it spreads around the earth, looking for gaps to penetrate. The result is about 1% The particle penetrated into the atmosphere near the North Magnetic Pole. Each solar particle contains an electrical power equal to 1000 volts. They encounter atoms and molecules mostly composed of oxygen and nitrogen in the high-altitude atmosphere 100 kilometers away. When the atoms absorb part of the energy contained in the sun's particles, they immediately release this energy to produce extremely strong light.

Using a metaphor, it can be said that aurora activity is like a live TV picture of magnetospheric activity. The falling particles are the electron beams of the television, the earth's atmosphere is the television screen, and the earth's magnetic field is the electron beam guiding magnetic field. Scientists have obtained a large amount of information about the magnetosphere and the electromagnetic activities in the sun and earth space from this large natural TV. For example, through polar spectral analysis, we can understand the source of the falling particle beam, the type of particles, the amount of energy, the structure of the Earth's magnetotail, the interaction between the Earth's magnetic field and the planet's magnetic field, and the way and extent of the impact of solar disturbances on the Earth.

It can be repaired. The main maintenance contents of diesel generator sets include (due to the differences in performance and usage conditions of various generator sets, the standards listed are for reference only and should be operated according to the specific circumstances) Minor fault inspection: Check the unit Minor faults, deformation of the cylinder cover due to lack of water, deformation of the body, etc., damage to the internal moving parts, etc., should be less likely to cause the cylinder to stick due to lack of oil, and require professional inspection and repair. Minor repairs: (Usage time: 3000-4000 hours) 1. Check the valve of the diesel generator set. Dongfanghong diesel engines are widely used in construction machinery and agricultural machinery; The working condition of PT pump and injector of diesel generator set, medium repair: (Use time: 6000-8000 hours) 1. Includes minor repair items of diesel generator set; 2. Disassemble the engine (except crankshaft); 3. Check cylinder liner, Pistons, piston rings, intake and exhaust valves, crank and connecting rod mechanisms, valve trains, lubrication systems, cooling systems and other vulnerable parts should be replaced when necessary; 4. Check the fuel supply system of the diesel generator set.
