本文提出了一种求解波动方程的近似方法,我们把它称为配置有限单元方法,即对空间坐标的量纲用有限单元方法,而对时间的量纲用配置法.这种近似方法看来精度是很高的,并且能适应于各种边界的特点;最后得到的代数方程式的系数矩阵也是对角型的.这些优点有可能填补惯用的半离散化近似方法的不足. In this paper, we propose an approximate method for solving the wave equation, which we call a finite element method, that is, a method of dimensioning space coordinates using a finite element method and a dimensioning method for time. The accuracy is high and can be adapted to the characteristics of various boundaries. The resulting coefficient matrix of algebraic equations is also diagonal, which may possibly fill in the deficiencies of the conventional semi-discretization approximation methods.
