nutation angle

Order , the authors present the expression of precession - nutation of cip . theoretical result shows that odd order s precession - nutation moment causes out - of - phase longitude and obliquity nutation namely , there are cos term in longitude nutation , and sin term in obliquity nutation . moreover , it proves that the expression of precession is independent of earth model 理論研究表明,奇數階歲差章動力矩使得黃經章動和交角章動出現了異向項即黃經章動出現了cos項,交角章動出現了sin項,同時也證明了歲差表達式與地球模型無關。

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 基于經典的彈性地球自轉動力學理論,通過引入章動參考系相對慣性空間的運動,建立了彈性地球極移和章動的聯合動力學方程。

This paper presents the basic construction and movement rules of the coordinator gyrorotor with reticle of archimedes spiral reticule pattern , also , it explains the principles and methods of dynamical balance to damp the vibration and forced nutation 闡述了具有阿基米德螺旋線圖案的位標器的基本原理及其運動規律,并說明這種陀螺轉子的振動與繞動的平衡原理與方法。
