摘要
本文首次探讨了对弹性波在传播过程中的反射和波型转换有任制作用的弹性波方程的形式。给出了三种弱转换、弱反射弹性波方程和一种无转换弹性波方程。由于这些方程的弱反射、弱转换特性,使它们特别适用于需要压制层间混响的弹性波道时递推成像一类的工程。文中给出的弹性波成像算例,初步证实了这项研究的有效性。
Several approximate elastic wave equations in which reflection and conversionare weaker than in accurate ones are first discussed in the paper. They include threeelastic wave equations involving weak conversion and weak reflection,and one elas-tic wave equation having no conversion. Weak reflection and weak conversion makethe elastic wave equations be applicable to the elastic-wave reverse time recursionimage problem where interbed reverberation must be suppressed thoroughly. A trialexample of elastic wave image proves this research result useful.
