| 摘 要： | 应用热力学方法讨论了球面电磁波的熵函数，由于电磁波的传播过程是一个非平衡态辐射过程，因此用非平衡态热力学的理论，运用吉布斯关系式，光压的数学表达式等重要关系，最终得出电磁波的辅射过程是一个嫡增加的过程．

| Abstract: | The entropy function of spherical surface electromagnetic wave is discussed by the method of thermodynamics.Noting the fact that the propagation of electromagnetic wave is a radiation process of nonequilibrium state, by using the theory of thermodynamics for nonequilibrium state,Gibbs relations and expresion of light pressure, it is obtained that the radiation of electromagnetic wave is a prosess of entropy incereasing. |
