| 摘 要： | 用广义变分法处理了介质层中电磁波的传播问题，把介质界面处的电磁波视为一个受约束的系统，采用广义变分法基于在坐标变换下的变换性质，推导了两个介质界面附近电磁波的一些性质，由这些性质导出了反射和折射电磁波在介质层中移动的物理机制。

| Abstract: | Deah with the problem of propagation of electromagnetic waves in layers of dielectric media according to the generalized variational principle, regarded the electromagnetic waves influenced by the interface of dielectric media as a constrained system,dealt with some properties of the constrained system under transformation of coordinates according to the generalized variational principle. These led to internal cause of physics of shift of reflection and refraction electromagnetic waves in layers. |

| Keywords: | generalized variation electromagnetic waves constrained system layers of dielectric |
