摘要/Abstract

摘要： The formula of BEM suited to solve the problems of wave propagation in boundless medium is obtained from numerical treatment of Kirchhoff integral equation. After quoting the coefficients of refraction and reflection of wave at surface or interface, the expression of BEM which is suitable for the problems of wave propagation in multi-isotropic mediums is also given.

关键词: nonlinear wave equations, priori estimate, time periodic solution
