汞弧光放电是一种低气压气体放电现象，放电电流密度大。

The discharge of mercury arc is electric discharge phenomena of low pressure gas and the current density is great.

分别考察了气体压力、气体流量、电池温度及不同放电电流密度等条件对电池电流分布的影响。

The effects of operation conditions, such as temperature, pressure and flow rate, on current distribution were discussed.

然后由其解析解计算这种无声放电的着火特性和放电电流密度对时间的依赖关系，并与实验结果相比较。

Then, the breakdown characteristics and the de-pendence of discharge current density on time are theoretically calculated in this kind of AC silent discharge.
