摘要
各向异性研究是当令地震学研究领域中重要课题之一;三分量地震资料中各向异性的检测是各向异性理论研究成果解决地球科学实际问题的重要桥梁。本文简要描述了各向异性介质中横波分裂现象,分别介绍了现有的四种主要检测技术,即偏振图法、协方差拒阵法、质,点振动分辨率法及传输矩阵法,并对这四种技术作了一定的评述。
The study of anistropy is one of important subjects in seismdogicalresearch field,the dection of anistropy in 3- components is a important method by whichthe theoretical achivements of anistropy could be used to solve many problems related toearth science. The shear- wave splitting phenomenon in anistropic media has beendescribed.The four kinas of detecting techniques, named polarization diagrame method,covariance matrix method particle motion discriminant method and propagator matrixmethod,have been introduced and discussed in the paper.
