趋肤效应的实质是一种电磁波的传播行为。一般研究仅从趋肤深度的角度理解趋肤效应。通过分析电磁波经过不同媒质界面时会形成的反射波和透射波，给出了两种媒质中的电磁场表达式及平均能流密度的表达式。根据媒质电导率的不同，推导出相应的平均能流密度的计算公式，从平均能流密度的角度，诠释了趋肤效应的本质。

The essence of the skin effect is a kind of propagation behavior of electromagnetic wave.The explanation about the skin effect in the existing teaching materials is only based on the skin depth.In this paper,through the analysis of the reflection wave and transmission wave formed when the electromagnetic wave is passing different media interface,the expressions of the electromagnetic field and the average energy flow density are given for two kinds of medium.According to different conductivity of the medium,the cal-culating formula of corresponding average energy flow density is derived,and the nature of the skin effect of the average energy flow density is explained.
