density ionization

Above this density, microwave field will damp rapidly, so the gas ionization is mainly on the surface.

超过此密度后，微波场在表面快速衰减，气体电离主要在表面进行。

A dynamic equation of plasma density is constructed about ionization, recombination, diffusion and plasma flow which is produced by inhomogeneous pressure.

考虑等离子体中存在电离和复合这两种互逆过程及扩散和压力不均匀引起的等离子体流动，建立密度动力学方程。

Thetheoretical calculations and the experiments suggest that, double pre-ionization has an obvious advantage for increasing the initial electron density between the main electrodes.

理论计算与实验表明，双预电离在提高主电极间初始电子密度方面存在着明显的优越性。
