If you know plasma, please come in

Plasma. Plasma is an ionized gaseous substance composed of atoms after partial electron deprivation and positive and negative electrons produced after atoms are ionized. Plasma is a good conductor of electricity, using a cleverly designed magnetic field to trap, move, and accelerate it.

The development of plasma physics provides new technologies and processes for the further development of materials, energy, information, environmental space, space physics, geophysics and other sciences.

The seemingly "mysterious" plasma is actually a common substance in the universe, with plasma in the sun, stars, and lightning, which accounts for 99% of the entire universe. It is now mastered that plasma is controlled using electric and magnetic field generation. For example, welders weld metals with high-temperature plasma.

Plasma can be divided into two types: high-temperature and low-temperature plasma. The above mentioned is high-temperature plasma.

Today, low-temperature plasma is widely used in a variety of production fields. For example: plasma TV, waterproof coating on the surface of baby diapers, increasing the barrier of beer bottles.

More importantly, the use of etching in computer chips has made the Internet era a reality.

High-temperature plasma occurs only when the temperature is high enough. The sun and stars constantly emit this plasma, which makes up the 99 of the universe. Cryogenic plasma is a plasma that occurs at room temperature (although the temperature of the electrons is very high).

Low-temperature plasma can be used for surface treatment such as oxidation and denaturation, or for precipitating coatings on organic and inorganic substances.

Plasma is the fourth state of matter, the ionized "gas", which exhibits a highly excited and unstable state, including ions (with different symbols and charges), electrons, atoms, and molecules. Actually, people are not new to the phenomenon of plasma. In nature, blazing flames, dazzling lightning, and the magnificent aurora are the result of plasma.

For the entire universe, almost 99 9 or more matter exists in the plasma state, such as stars and interplanetary space, which are composed of plasma. Plasma can be produced by artificial methods such as nuclear fusion, nuclear fission, glow discharge, and various discharges. The internal structure of a molecule or atom is mainly made up of electrons and nuclei.

Under normal circumstances, that is, in the first three forms of the above-mentioned substances, the relationship between electrons and nuclei is relatively fixed, that is, electrons exist around the nuclear field at different energy levels, and their potential energy or kinetic energy is not large.
