摘　　要：本文较详细地讨论了单色平面机械波的横波、纵波在理想媒质(无吸收,各向同性的弹性固体)分界面上入射时,反射波、折射波的相位变化.证明了机械在入射界面反射时存在"半波损失"与媒质性质和入射角的关系.This article discussed the phase changes of reflective and refractive waves which were formed by the monochromatic plane mechanical wave on the bound surface of two ideal medium. The paper has proved that when mechanical wave runs into the bound surface, the reflective wave would lose the half-wave, which is interrelated with the character of the medium and the angle of incidence.
