| 摘 要： | 全球扭转构造体系不仅是球面现象,而且波及整个地球.本文着重指出地球圈层耦合扭转的机制,揭示该机制对于板块构造的控制规律.赤道面与银道面的交角达62°36′,当银心从北天球移动到南天球时,在公转离心力的驱动下,塑性地幔将向南半球运移而大陆板块则向北半球漂移,从而导致南、北半球的非对称性和两半球的相对扭转.地球的大陆漂移的节律与银河系涡旋周期一致,太阳系内旋转状态相同的行(卫)星与地球同步扭转.

| Abstract: | The global torsion tectonic system does not only involve the surface but also the interior of the spherical Earth. This paper describes emphatically the mechanism of the coupling of twisting of the Earth''s individual spherical layers, that controls the plate tectonics.
There is an inclination of 62°36'' between the Earth''s equator and the galactic equator. When the galactic center moves from the north to the south of celestial sphere, the plastic mantle of the Earth will migrate towards its southern hemisphere and the continental plate will drift to its northern hemisphere under the control of the centrifugal force of revolution. Such a process will lead to the asymmetry of southern and northern hemisphere and a twisting of the two hemispheres. So there is a correpondence between the rhythm of the Earth''s continental drift and the cycle of spirals of the galaxy. In solar system planets (or satellites) which revolves in the same way as the Earth will undergo a synchronous twisting. |
