The plasma is the fourth state of matter, the ionized "gas", which exhibits highly excited unstable states, including ions (with different symbols and charges), electrons, atoms and molecules. In fact, people are not unfamiliar with the plasma phenomenon. In nature, fiery Shuoshuo flames, brilliant flashes of lightning, and gorgeous aurora are all the results of plasma action. For the entire universe, almost 99. More than 9% of the matter is in the plasma state, such as stars and interplanetary space is 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 composed of electrons and atomic nuclei. Under normal circumstances, that is, the first three forms of the above-mentioned substances, the relationship between electrons and nuclei is relatively fixed, that is, electrons in different energy levels in the vicinity of the nuclear field, the potential energy or kinetic energy is not small.
When ordinary gas temperature rises, the heat movement of the gas particles intensifies, causing a strong collision between the particles, a large number of atoms or molecules in the electrons are knocked off, when the temperature of millions of open to 100 million, all gas atoms all ionized. The total negative amount of the free electrons ionized is equal to the total positive charge of the positive ions. This highly ionized, macroscopic, neutral gas is called a plasma.
