Ma Zongjin thought that the orientation of relatively westward drift of lithosphere and eastward motion of mantle may show oriented action of change of the earth's rotation. This paper provides a proof that the Coriolis force is the cause fordifferential rotation of the lithosphere and mantle.

马宗晋认为,岩石圈的西向漂移和地幔东向运动的定向性显示了地球自转变化的导向作用[1]。本文证明,地球自转中的一种惯性力──科里奥利力是产生地球各圈层差异旋转的原因。

In the process of the gravitative differentiation, the masses, of the earth and the energy of rotation grther in to the earth core at the same time. It makes the core rotate faster and faster than the otherparts.As the energy of position decreases. some of it turn into the energy of rotation. The turning core can provide the energy and dynamics for the magnetic effect, core convection and mantle plume.

在重力分异过程中,地球的质量在向地心集中的同时,其自转动能也向地核集中,从而产生地核、地幔和岩石圈三者的差异旋转运动。因重力位能降低而释放的大量能量,并未完全变为热能,其中有一部分变为地核的自转动能。这部分能量的存在和释放,为地磁效应,液核对流和热幔柱形成提供能源和动力。

Coriolis force is the reason for earth differential rotation. During the masses gather in the center of the earth, the rotational energy will gather in the core also. So, there is differential rotation among the crust, mantle and core. The force which opposes the differential rotation turns the rotational energy into the thermal energy. The thermal energy is gathered in CMB and plumes are formed.

科氏力是地球各圈层差异旋转的原因。在重力分异过程中,随着地球质量不断向地心集中,地球自转动能也不断向地核集中,从而产生圈层分化和差异旋转。地核相对地壳、地幔高速旋转,具有巨大动能,旋转阻力不断将其转化为热能,在核幔边界聚积起来,为液核对流和热幔柱提供足够的能量。
