本文较详细地介绍了群速度频散测定的多重滤波法，以及ＬＳＱＲ反演方法运用于网格频散反演和地球内部结构反演的地震面波频散的层析成像方法。给出了计算程序框图及数值模拟结果
In this paper, we introduce the multi-filter method of group velocity dispersion measurement in detail and the tomographic method of LSQR inversion applied to the seismic surface wave dispersion in grid inversion and earth's internal structure inversion. The calculation block diagram and numerical simulation results are given
