摘要
我国学者原创的洋壳流力学,以海底扩张理论为基础,进一步认为海岭顶部涌出的物质不只是向两侧作简单更新和扩张运动,同时存在复杂有序的后续相互力作用。如运用宏观统计的方式,发现太平洋洋壳流以一定的运动方向、力作用与陆地、海岭相遇,必然产生相对应的具有鲜明特点的地形地貌,并绘出该区域现代洋壳流运行路线,由此推出地壳表面地形地貌的形成,是洋壳流运动与陆地相互力作用的结果。洋壳流力学分析方法使地球从南端到北端,从东半球到西半球之间的地质力学分析更细腻,更精确,更能体现全球地质运动的整体性,为一种领先的新地质力学理论。
The original mechanics of oceanic crust current created by Chinese scholars is based on theory of seafloor spreading.It believes that the material from the top of the Ridge does not only simply renew and expand to the sides,but also there are complex and orderly follow-up interactions.Macro statistics indicates that the Pacific oceanic crust current movement is inevitable to produce the corresponding topography and landform with distinct characteristics.Analytical method of oceanic crust current mechanics better reflects the global geological movement as a whole.
