If a forward voltage is applied to the thruster before this interval has passed, the device may prematurely turn on and damage to the device and circuit could result.
如果在这间隔时间结束之前加一正向电压到半导体闸流管，设备可能过早地启动，并可能导致设备和电路损坏。

The principle and research status of pulsed plasma thruster (PPT) were put forward in this paper.
论述了脉冲等离子体推力器（PPT）的工作原理和研究状况。

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.
