【摘要】 地球内部各圈层的结构和构造在本质上是不均匀的和各向异性的 .各向异性的研究不论是对深化地球本体的认识 ,还是在资源、能源、灾害和环境以及全球变化的研究中均具有重要作用 .本文基于这一科学问题的本质性和重要性着重讨论了以下 5个问题 :1 )各向异性介质中地震波场效应与判据 ;2 )复杂介质地震各向异性———S波分裂的成因分析 ;3)当今S波分裂监测技术的进展与探索 ;4)地震各向异性在不同科学问题研究中的效能 ;5)地震各向异性在地球科学发展中的作用与今后的任务 .更多还原

【Abstract】 The structure and tectonic of Earth’s interior media are intrinsically inhomogeneous and anisotropy. Anisotropic research of media have very important action for deep understand of Earth’s itself,Resource,Energy source,Natural calamity,Environment and Global change. In view of these,we are discussed following five problems. 1 The effect of Seismic wave field and criterion in anisotropic media. 2 Anisotropy of complex media——analysis for cause of splitting of S wave. 3 The progress and explore for detecting techniques of splitting of S wave. 4 The application effect of seismic anisotropy in different science fields. 5 The function and from now on tasts of seismic anisotropy in development of Earth’s Science.更多还原
