【摘要】 以分裂剪切波观测为基础,人们对壳幔介质变形强度和方向的时空变化图像进行了深入研究。研究结果对解释板块运移和地幔对流规模、深源地震成因和浅部地震构造活动及其深部背景力源问题具有重要意义;在地震预测、石油探测和地热开发等领域具有十分诱人的应用前景。文章最后,作者提出了应着重深入研究的问题。更多还原

【Abstract】 Based on the observation of splitting of shear waves, scientists have made a deepgoing study into the time-space change pattern of shape distortion strength and direction of the crust mantle media. The results of the study have very important significance for explaining plate motion and mantle convection scale, the origins of deep focus earthquakes, shallow seismotectonic movement, and deep back ground force source. The prospects of application of the results are very attractive in the fields of earthquake prediction, oil exploration, and earth heat exploitation. Finally, the authors of this paper put forward some problems which should be subject to deepgoing study in the future.更多还原
