The electric field within a closed, empty conductor is zero, so the cup shields the object placed inside it from any atmospheric or stray electric fields.

由于闭合、中空导体中的电场为零，所以，使用法拉第杯就把放在其内部的物体屏蔽起来，不受大气的或任何寄生的电场的影响。

Based on the large structure state of atmospheric temperature, the theoretical basis of the best observation time obtained through the two times electric ranging has been discussed.

本文根据大气温度层结状态，讨论两种光电测距最佳观测时刻的理论。
