polarmotion
wandering of the pole
Examples
- The wobble and precession - nutation on cip of elastic earth
弹性地球cip轴的极移和岁差章动 - Apparent polar wander path
视极移曲线 - Reduction for polar motion
极移改正 - Therefore , the theoretical definition of cip and its dynamical equation on wobble and precession - nutation are given . considering precession - nutation moment up to 5
由此对cip轴进行了理论定义，并给出了其极移岁差章动的动力学方程。 - Based on classical dynamical equation on elastic oarth rotation , an associated dynamical equation containing both nutation and wooble of earth rotation has been deduced through introducing motion of nutation frame with respect to inertial spatial frame
基于经典的弹性地球自转动力学理论，通过引入章动参考系相对惯性空间的运动，建立了弹性地球极移和章动的联合动力学方程。
