摘　　要：该文的主要目的是确定电热轻气炮放电室中的电弧电阻，给出了计算电弧电阻的２种工程计算方法。其中平均电阻法直接由电弧电阻与充气压力、初始电能密度的实验拟合公式确定电阻；电弧通道法则根据电弧的特点推出电弧电阻公式，并通过实验确定有关系数。２种方法均可在电热轻气炮研究的不同情况下获得应用。针对１２７ｍｍ电热轻气炮，文中给出了有关参数分析结果。The main objective of this article is to determine the arc resistance in the light gas electric generator's discharge chamber.Two different engineering methods of arc resistance calculation are presented.In the method of average resistance,the average arc resistance is determined directly by the experimental fitting equation on the initial gas pressure,the arc resistance, the initial density of electrical energy.In the method of arc channel,an arc resistance equation is deduced according to the characteristic of arc,and the constants in the equation are determined with the experimental results.These two methods can be used to meet different demands in the study of electrothermal light gas gun.The parametric analysis results of 12 7mm ET gun are presented in this paper.
