When these characteristics are considered and assume that the interface of sea water and sediment is a plane, the expression of reflectioncoefficient is derived.
考虑到这些特征，再假设海水与沉积物的界面是平的，导出了平面声波在其上的反射系数的表达式。

For scattering of a bounded acoustic beam from a liquid-solid interface, the principal difficulty comes from the treatment of tie plane wave reflectioncoefficient.
