摘要
When plasma is generated by applying high-voltage alternating current (AC), the driving force of the temporally and spatially varying electric held is applied to the plasma. The strength of the driving force of the plasma at each spatial position is different because the electrons constituting the atmospheric-pressure nonequilibrium (cold) plasma move at a high speed in space. It the force applied to the plasma is accelerated only by the dining force, the plasma will be accelerated infinitely. The equilibrium between the driving force and the restricting force due to the collision between the plasma and neutral particles determines the inertial force and the drift velocity of the plasma. Consequently, the drift velocity depends on the strength of the time-averaged AC electric field. The pressure applied by the AC electric field equilibrates with the plasma pressure From the law of conservation of energy, the pressure equilibrium is maintained by v arying the drift velocity of the plasma.
