The research of the seismicbehavior on the inner interface has important meaning for the understanding of the seismicpropagation and the interpretation of the sophisticated 3-component seismic records. So far,a few publications about it have been published. In this note, starting from the waveequations and using continuous conditions at the interface, we have derived the reflectingand transmission coefficients on the inner interface in three-domain anisotropic media.展开更多
