The differential rotatio n is based o n Co riolis effect ,w hich can exert ho rizo ntal movement into vertical moving bo dies. It′s dynamic significances are : (1) A rotary system has different mo de of mat ter motio n and energy t ransfo r matio n f ro m no n - rotary system ; (2) The state of t he differential rotatio n in o rder is alter nate wit h t hat in diso rder ,t hus t he geo2 magnetic field wo uld be reversal ; ( 3) As t he differential rotatio n of t he eart h inner co re ,t he solar radiatio n causes elect ro magnetic co upling and angular mo ment um exchange bet ween t he co re and mantle ,w hich co nt rols t he liberatio n of t he eart h′s inner energy.
