泄漏电流随时间呈指数衰减，所以通常需要在一个已知的时间期间内施加电压(浸润时间)，然后再测量电流。
The leakage current will decay exponentially with time, so it's usually necessary to apply the voltage for a known period (the "soak" time) before measuring the current.
在这两种应力条件下，应力导致的漏电流与时间的关系均服从幂函数关系，但是二者的幂指数不同。
Under both stress conditions stress induced leakage current follows a power law against stress time with different power factors.
由于材料按指数形式不断充电，所以施加电压的时间越长，测量出的电流就变得越低。
The longer the voltage is applied, the lower the measured current becomes because the material continues to charge exponentially.
