摘要
在层次不均匀介质的参数反演中,波场的表达起着重要的作用。作为[1]的一个特例,文[2]在介质无吸收时,得出如下结果。定理1
In this paper, the wave fields in layered-inhomogcncuous media which is described by wave equation with discontinuous coefficient is discu-ssed. As the linear waves are superposable, we decompose the layered-inhom-ogeneuous media into layered-homogeneous media and continuous inhomogen-euous media, their wave fields are derived by introducing the propagation operator and Riemann function respectively, thus the known proof is simp-lified.
