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 阐述了具有阿基米德螺旋线图案的位标器的基本原理及其运动规律，并说明这种陀螺转子的振动与绕动的平衡原理与方法。
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。
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 理论研究表明，奇数阶岁差章动力矩使得黄经章动和交角章动出现了异向项即黄经章动出现了cos项，交角章动出现了sin项，同时也证明了岁差表达式与地球模型无关。
