摘要
This paper discusses variation characteristics of transmitted wave energy of 6 types of seafloor with different lithologies (silt, tuff, powder-grained sandstone, coarse-grained sandstone, limestone and granite) with respect to the incident angle, which is based on theories like coefficients of liquid-solid interface and energy function. The situations of transmitted wave energy distribution turn out with great differences in terms of different seafloors and the same conditions of acquisition.
