摘要
本文简要地阐述了弹性波传播的一些基本理论,如位移势,表现定理及特征线理论等,并评述了两个领域内的问题。一为无限介质,半无限介质及层状介质中波的传播问题,重点在于地震波传播问题的解法。另一个领域为弹性波的绕射和散射。这一问题在动断裂、无损探伤及地震学中有重要的应用。评迷的重点是解题方法。 对本学科将来的发展也作了展望。认为反问题,随机波理论和在新技术领域中的应用是发展方向。
The fundamental theory of elastic wave propagation, such as the displacement potentials, the theory of representation and the theory of characteristics, is briefly presented.The wave propagation in half space and stratified layers and the scattering of waves by inclucions and cracks are reviewed. Emphasis has been put on the applications in various practical fields and the new approaches for solving these problems.The progpect of the development of the theory of elastic wave is also included. The inverse problem, the stochastic wave propagation and some important applications are mentioned.
