Abstract
Plasma technology is the forefront of today's scientific research, which has been widely used in various fields of national economy. By starting from the concept of plasma, we have described the technique of plasma, its formation mechanism, and plasma applications. In this paper we focus on gas discharge producing plasma, through DC glow discharge experiment to survey the electrical properties of glow discharge plasma. The main purpose of this paper is to observe gas discharge plasma so as to understand the nature of the characteristics of areas, and measure the glow plasma volt-ampere to get volt-ampere characteristics through (FB7008)-type multi-plasma gas-discharge experimental apparatus. According to the curves, we can obtain electron temperature Te, electron density ne, and the average kinetic energy We .
