摘要
本文根据地极移动引起地球上各点向心力的变化,导出了一个全球构造力学模型。把这个力学模型计算的力矢量展布于地球表面,可以非常直观地显示大陆漂移和海底扩张在这些力的作用下如何进行运动。这些运动的方向和规模与力的分布协调一致,有力地揭示了大陆漂移、海底扩张、地极移动之间的内在联系,为全球构造提供了一个新的定量力学模型。
According to the principle that the movement of the earth's rotational poles causes change of the centripetal force on each point of the earth , the paper conducts a mechanics model for global tectonics . Spreading out these force vectors of mechanics model on the earth's surface , it can be directly seen how the continental drifting and sea- floor spreading are in motion affected by these forces .The motion's direction and scale are in such a harmony with the force's distribution . It powerfully shows the internal connection among the continental drifting , sea-floor spreading and movement of the earth's rotational poles .All of this has given a new quantitative mechanics model for global tectonics .
