通过位移位表示的反射系数和透射系数方程，通过求解佐普利兹方程，可得到位移振幅的反射系数与透射系数的表达式；从而可以借助其推断介质的物性参数。基于这一原理，在80年代发展了AVO技术。-By solving the zuopulizi equation, displacement amplitude of the reflection and transmission coefficients can be obtained expressions of physical parameters which can be inferred through its medium. Based on this principle, AVO technique was developed in the 80　s.
