摘要

根据交换平衡力学原理[1],简要地介绍了洋壳流的概念及其运动特点。根据运行区域和方向的不同,把三大洋的海底扩张运动划分为不同的洋壳流,并绘出运行路线图。提出洋壳流运动方向、路线及力作用大小的判断方法,通过不同区域洋壳流相互力作用的对比,分析海底扩张运动对地震时空分布及变化规律的影响。
According to the principle of exchange equilibrium mechanics[1], the concept and moving characteristics of oceanic crust current is briefly introduced in this paper. Based on the theory of sea floor spreading and the method of crustobody’s evoluting-moving analysis, the sea floor spreading movement of three oceans can be categorized into different oceanic crust currents. Those movement routes have been figured out. The judgment on their directions, routes and efforts also have been put out. Through the comparison of interaction of different oceanic crust currents, the space-time development and distribution law can be brought out.
