摘要：
The invariant imbedding procedure with a modified planar wave-splitting process is applied to the dissipative wave equation for a smooth stratified medium. The imbedding equations for R0 and R2, respectively the zeroth and second moments of the kernel of the reflection operator, are obtained. A linearization of the nonlinear imbedding equation for R0 is given, which greatly simplifies the numerical procedure and improves the speed one order in the direct and inverse problems. Numerical results are given for the direct problem, and for the inverse problem where the zeroth and second transverse moments of the reflection data are given on one side.
