电路参数对外电极气体放电过程影响的计算机分析

本文通过对外电极气体放电物理过程的计算机模拟,研究了一些主要电学参量(包括电源电压、外电路阻抗、介质层电容和介质层上的壁电荷等)对放电过程的影响.文中给出了关于放电电流、辐射亮度和电功损耗等项放电特性随外电路阻抗变化的一维数值分析实例.

Numerical Analysis of the Effect of Some Electric Parameters on AC Gas Display Discharge

Through a computer simulation of AC gas discharge in penning mixture (neon plus about 0.1 percent argon ) with parallel external electrodes, the effect of some major electric parameters ( e.g.drive voltage, circuit impedance, capacitance of the dielectric layers, and wall charge on layers) on the physical process of AC gas discharge is studied.This paper presents some examples of the one-dimensional numerical analysis of the discharge characteristics, such as discharge current, light-output and power consumption, and versus impedance in circuit.
