摘要
阐述了采用叠加原理，将某些二、三维波动方程的初值问题化为一维波动方程的初值问题，进而用达朗贝尔公式对其进行求解的方法．采用这种方法，使这些二。
A methad for solving some initial-value problems for two-\ and three-dimentional wave equations are presented, in which the initial-value problems can be firstly simplified to that of one-dimentional wave equations by means of the overlying principle, and the latter can be further solved by D′alembert formula.
