| 摘 要： | 本文讨论了由一个刚性慢和一个液体核组成的行星的自转运动。得到了三组平衡解,并对其进行了详细的讨论。探讨了平衡解附近的运动,特别研究了两种极限情况。得到了由于液核的存在角动量轴趋向于形状轴的结论。分析表明行星核的大小及其动力学扁率决定了自由摆动的频率。

| Abstract: | The rotation of a planet with an ideal liquid core and a rigid mantle is discussed in this article. Three families of equilibrium solutions are obtained and discussed in detail. The motions near the equilibriums are explored, especially with two limit cases. It is shown that the angular momentum axis tends to the figure axis because of the existence of a liquid core, and the frequences of the free wobble are determined by the size of the core and the dynamical flattening. |
