Supernormal catalytic function of discharge plasma in the ageing process of dielectric

Plasma chemical reactions on a dielectric surface under discharge pulse conditions have been studied. A new model of a dielectric rectangular cavity is presented in studying this kind of reaction. Reactions are studied based on simultaneous nonstationary chemical kinetic equations and stationary wave equations. Furthermore, by using the Vlasov equation and the plasma dispersion law, the dipole layer effect caused by fluctuations on the dielectric surface has been studied. The results show that the thickness of the dipole layer is determined by the disturbance from the discharge pulse and the cohesion energy of electrons in the plasma. Cohesion energy and the pulse wave will excite various free radicals, resulting in a supernormal catalytic function in the ageing process of the dielectric
