推迟势的格林函数法

GREEN FUNCTION METHOD OF RETARDED POTENTIAL

用类似于解静电场的泊松方程的格林函数法，也可以用一种简单的方法先求出变化电磁场势方程的格林函数，然后应用迭加原理求出电磁场的推迟势．

The electrostatic equation was solved by use of the Green function which led to the superposition integral for electrostatic potential in terms of the charge distribution. We shall abopt a similar technique here to find the dl Alembert equation.
