在t1期间，通过半导体闸流管维持一反向电压，并且正是在这之后，设备易于保持一正向电压，而无需开启电源。

During t1 a reverse voltage must be maintained across the thruster and only after this time is the device capable of blocking a forward voltage without going into its on-state.

半导体闸流管数据表显示，在t1间隔时间期间生成一特定的反向电压以及这间隔时间随之而来的率上升特性的电压。

Thruster data sheets specify t1 with a specified reverse voltage applied during this interval as well as a specified rate-of-rise of voltage beyond this interval.
