当今中国大陆地壳移动的动力

THE MOTIVE FORCE OF PRESENT SHIFT OF THE CONTINENTAL CRUST IN CHINA

地幔圈形状周期性变化使地壳产生势能 (位能 )力导致地壳运动。当地幔圈由圆相对变扁 ,南、北半球的高纬度区地壳向低纬度区对挤 ;当地幔圈由扁相对变圆 ,恢复等位面平衡 ,南、北半球低纬度区的地壳区分别向高纬度区挤压。当今中国大陆地壳移动的动力是由于西部地区的地幔还在继续进行恢复等位面平衡产生的。

That the cyclical change of the shape of the mantle produces potential energy force in earth's crust results in crustal movement.When the shape of the mantle changes from sphere to relative flat-sphere,the crust of region of high latitudes of Southern Hemisphere and Northern Hemisphere produces opposite pressure to the crust of the region of low latitudes;When the shape of the mantle changes from relative flat-sphere to sphere due to restoration to a balance of the isopotential surface,the crust of the region of the low latitudes of Southern Hemisphere and Northern Hemisphere produces respectively a pressure to the region of the high latitudes.The motive force of present shift of the continental crust in China results from proceeding still to a balance of the isopotential surface in the mantle in the west of China.
