Background

Plasma (plasma), also known as plasma, is an ionized gaseous substance consisting of atoms deprived of part of electrons and positive and negative ions produced by ionization of radicals, a macroscopic electrically neutral ionized gas with dimensions greater than the debye length, whose motion is dominated mainly by electromagnetic forces and exhibits a pronounced collective behavior. The plasma is a good electric conductor, and the plasma can be captured, moved and accelerated by utilizing a magnetic field which is skillfully designed. The development of plasma physics provides new technology and process for the further development of science such as materials, energy, information, environmental space, space physics, geophysical and the like. Plasma is a fourth state of matter different from solid, liquid and gas. A substance is composed of molecules, which are composed of atoms, which are composed of a positively charged nucleus and negatively charged electrons surrounding it. When heated to a sufficiently high temperature or for other reasons, the outer electrons become free electrons free from the nuclei, as if the student after class runs to the playground to play at will. The electrons leave the nucleus, a process known as "ionization". At this point, the material becomes a uniform "paste" of positively charged nuclei and negatively charged electrons, and is thus called a plasma because it is called a "paste" by chance, which is a paste of ions of equal total positive and negative charge and therefore nearly electrically neutral.
