实际地球是一个非旋转对称的椭球体,甚至是梨形椭球体。因此,三轴整体地球自转动力学的理论研究是有一定意义的。主要将研究三轴刚体地球自转的自由摆动,对有关学者提出的分解定理进行重新探讨,指出了其中可能存在的一些问题。
The true earth is a non - rolling - symmetry ellipsoid, so much as is an ellipsoid as a pear. Thereby, the theoretical research on dynamics of triaxial whole Earth rotation has definite meanings. This paper will restudy the free wobble of the triaxial rigid earth rotation, and the decomposition theorem given by some scholars, and indicate the to existent problems.
