熔断器时间-电流特性如图3，最小开断电流以上部分为虚线。

See chart 3 for the fuse time-current property. The upper section above the minimum break current is broken line.

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.

实验结果指出，器件的电流放大系数器件大j、3结特性硬，无效触发分流小，可有效地缩短开通时间。

The experiment shows that if the current amplifier factor is big, Junction J_3 is hard and the ineffective trigger branch current is low, the turn-on time can be shorten effectively.
