摘要
对于非齐次波动方程的求解问题,一般情况下,我们通过齐次化原理(Duhamel原理)来给出方程解的具体形式。在文中,首先将方程化为方程组形式,然后应用特征线法给出该方程解的另一种推导过程。
For the problem of solving the nonhomogeneous wave equation, generally, we rely on the principle of Duhamel. In this paper, we change the form of the equation, the result of the equation can be obtained by using the method of characteristic lines.
