首发时间:2013-06-13
摘要:当求解一维线性齐次波动方程的初边值问题时, 分离变量法使得偏微分方程转化成两个分别关于时间和空间的常微分方程.对于这两个常微分方程, 本文通过分析论证回答了应该先求解哪个方程的问题.

The discussion of solving order for separation of variables applied to the space time equation
Abstract:When the initial boundary value problem for one-dimensional linear homogeneous wave equation is solved, separation of variables makes partial differential equations into two ordinary differential equations in time and space. For these two ordinary equations, the problem that which equations should be solved first is demonstrated in this paper.
Keywords: one-dimensional homogeneous wave equation separation of variables solving order
