摘　　要：研究了弹性固体和粘弹性固体界面上的反射和透射问题,通过入射波和反射波的波势函数表达式及边界条件,得到位移和应力,进而得到了相关波的反射和透射系数.分析了连续条件的情况下入射角对相关波的反射和透射系数的影响.The reflection and transmission problems at the interface between elastic and viscoelastic solids were studied.By using the wave potential function expressions and boundary conditions of incident and reflected waves,displacement and stress were obtained,and the reflection and transmission coefficients of related waves were obtained.The influence of incident angle on the reflection and transmission coefficients of related waves under continuous conditions was analyzed.
