摘要
研究了高气压强电场电离区域的离子浓度分布的连续性方程,对电离区域的电离物的产生、消失和输运进行了研究。通过采用电离放电增加了输入能量密度、G值、电离占空比等,从而提高了离子产生率。通过外加电场和离子“雪崩”头部的本征电场的叠加作用,离子被束缚在放电通道中。对离子施加垂直电场方向的作用力,就能把电场中的等离子体成束输送出去。已经能够做到有效体积仅为1cm3的等离子体源,输运等离子体率达到1012cm-3.s-1。
The continuous equation of the ion concentration distribution in the ionized field at high atmosphere has been studied, and the generation, disappearance and transportation of ionized particles have been also investigated. The power density, G -value and fractional volume have increased by using the ionization discharge, and moreover the generating rate of ions is enhanced. Ions are trapped in the discharge channel when they undergo the joint effects of the external electric field and the self-induced electric field from the head of their avalanche. The plasma in the electric field can be drawn out as a bundle when the external force normal to the electric field is applied to ions. Transporting plasma with 10^12 cm^-3·s^-1 and plasma source with 1cm^3 valid volume have been achieved.
