摘　　要：本文阐述了声波在固体中的传播特性、评论了声学在固体性质研究中的重要性、涉及的内容包括弹性各向异性、非线性效应,声电效应,玻璃和超导体中的声速和声衰减,相变中的软模、高阶弹性模量和状态方程等。The propagating characters of acoustic wave in solid are expounded at first. Then the importance of acoustic study for solid are reviewed. The involved subjects are elastic anisotropism, nonlinear effect, acoustoelectric effect, acoustic velocity and attenuation in glass and superconductor, soft mode in phase transition, higher order elastic constants and high pressure equation of state and so on.
