The current at the channel base is specified, and use two time constants can get the much better shapes than single time constant.

模型对于特定的雷电通道底部电流，采用了汉时间常数，取得了比单时间常数更好的拟合效果。

When the potential reached 0v, there are three time constants, one inductance arc and two contain arcs.

极化电位至0 V时，阻抗谱上出现三个时间常数，对应两个容抗弧和一个感抗弧。

To reduce the error to 1%, about two rise times must be allowed, while reducing the error to 0.1% would require roughly three rise times (or nearly seven time constants).

为使误差降低到1%，必须等待大约两倍的上升时间。而为了使误差降低到0.1%，则必须等待大约三倍的上升时间(或者接近7倍时间常数的时间)。
