摘　　要：A numerical iterative model was derived from the difference method and a perturbation assumption to calculate the coefficient function of a wave equation. The method was used to solve the disaccord problem of numerical precision between the direct problem model and inverse problem model, and its serial problems using the old method. Numerical simulation calculation shows that the method is feasible and effective.A numerical iterative model was derived from the difference method and a perturbation assumption to calculate the coefficient function of a wave equation.
