钱德勒极移的激发机制研究

根据宋晓东等的地球内核差异旋转研究成果，提出“月球轨道运动改变地球各圈层角动量”的物理模型。太阳系星球（尤其是木星）在轨道运行过程中对月球的摄动会影响月球的轨道运动，月球轨道运动会改变地球各圈层角动量，在形成地核差异旋转的同时，也使地球液核远月半球的角动量与近月半球的角动量存在巨大落差，造成地轴的晃动，激发地球的钱德勒极移。

On the Excitation Mechanism of the Chandler Pole Shift

According to the research results about the core differential rotation studied by Song Xiaodong ,et al ,this paper put forward a physical model “the moon orbital motion changes the angular momentum of earth spheres” . The perturbation of the planets in solar system （especially Jupiter） to the moon in the orbital motion can affect the moon＆#39;s orbital motion ,the moon＆#39;s orbit motion can change the angular momentum of earth spheres ,form the core differential rotation ,at the same time , also make the angular momentum of the earth fluid core far lunar hemisphere and that of near lunar hemisphere exist huge head ,which can cause the shake of earth＆#39;s axis and arouse the earth＆#39;s Chandler pole shift .
