摘要： 本文从弹性波动方程出发,导出了弱非均匀介质中P波散射方程,并利用文献提出的外推场方法,在Born近似下反演P波速度及密度分布函数.

Abstract: In this paper, the P-wave scattering equation of a weak inhomogeneous elastic medium is derived from the elastic wave equation of an isotropic medium. The inversion procedure of P-wave velocity and density distributions of the elastic medium within Born approximation is presented, by using the extrapolating field methods developed in Refs.[1]and[2].
