摘要
本文用半离散方法将二维波动方程离散为一维耦合波动方程组．给出了离散的收敛性及波动方程组的适定性．利用这种方法可以求解波动方程系数及演问题．
The artical gives a semi-discrate method for solving direct and inverse problem of 2-D wave equation. By the method 1 2-D wave equation is discrated into one-dimension wave equation system f which is well-posed. The convergence of the semi-diserate method is given. The method is convenient to solve inverse problem of 2-D wave equation especially.
