This research continues a project on coupled free oscillations and the large-scale lateral heterogeneity of the earth. Specific tasks to be done now are the modification and improvement of the efficiency of the coupled-mode synthetic seismogram code, the increase of resolution of synthetic inversion studies of the structure of the earth, the study of surface-wave amplitude anomalies, and body waves in laterally homogeneous and laterally heterogeneous earth models. The theoretical and computer code results of this work will be widely applicable to studies of the earth's structure, earthquakes, and tectonics.

这项研究继续了耦合自由振荡和地球大尺度横向不均匀性的项目。 目前要做的具体工作是修改和提高耦合模式合成地震记录代码的效率，提高地球结构合成反演研究的分辨率，研究横向均匀和横向非均质地球模型中的面波振幅异常和体波。 这项工作的理论和计算机代码结果将广泛应用于地球结构、地震和构造学的研究。
