摘　　要：本文首次将域外源点边界元法应用于弹性动力问题中,在频域内研究了域外源点的配置规律,对数值解的稳定性进行了讨论。在分析中,使用了矩阵条件数概念。In the present paper, the boundary element method with exterior collocation is applied to elastodynamic problems for the first time,the collocation rule of source points out of the region being studied is investigated in the frequency domain, and the stability of numerical solution is discussed . In the analysis, the concept of condition number of matrix is used.
