【摘要】 本文对Wiggins方法提出两点改进,(1)半空间本征函数选为四个特定的指数函数的线性组合。(2)用求系数向量的基础解系的方法处理边界条件。改进后的方法比较合理,而且适用于各种纵向变速介质的地震面波频散和偏导数的计算。更多还原

【Abstract】 In this paper, Wiggins’ method has been improved in two aspects: (1) A. linear composition made up of four special exponential functions is selected for the eigenfunction in half space; (2) The boundary condition can be settled by a basie set of solution for eigenvector. The improved method in more reasonable and can be generalized to compute surface wave dispersion and partial derivatives in any longitudinal heterogeneous media.更多还原
