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(jīng)典的彈性地球自轉(zhuǎn)動(dòng)力學(xué)理論,通過引入章動(dòng)參考系相對(duì)慣性空間的運(yùn)動(dòng),建立了彈性地球極移和章動(dòng)的聯(lián)合動(dòng)力學(xué)方程。
