The two tests susceptible to junction heating are the forward voltage and leakage current tests.

对结发热最敏感的两种测试是正向电压测试和漏电流测试。

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.

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。

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。
