摘要

为了正确认识负离子在空气放电中的作用

计算了包含负离子的多组分漂移-扩散方程组

得到了随时间变化的电流密度、等离子体组分浓度、体积力密度

与无负离子的情况进行对比后发现放电中产生的负离子可加快放电起动速度

但使放电稳定性降低;它导致激励器放电功率降低

同时等离子体体积力的控制能力却得到增强;最后

负离子的存在延长了正离子寿命

可增强电离程度。

Abstract

For understanding the effect of negative ions in air discharge

the multi-component drift-diffusion equations are computed which include negative ion.The variation of discharge current density

plasma components density and body force density with time are gained.Compared with the case which doesn’ t include negative ions

it is found that the negative ions can quicken the start of discharge

but reduce the stability of discharge;and they decrease the power of discharge

but the control effect of plasma body force is improved;at last

the existence of negative ions prolong the lifetime of positive ions

and the ionization degree is higher.
