Studies and Detections on Both the Parameters of Earth Free Core Nutation and the Earth Free Oscillations

分析了章动常数误差与用连锁法计算的赤纬、自行改正之间的关系，并考虑了改正这种影响的方法。

The relation between the error of nutation constant and the corrections of declinations , proper motions calculated by chain method is analysed , and the method to correct this effect is considered .

本文的研究工作包括两个研究方向：上篇是液核自由章动常数的研究与检测，下篇是地球自由振荡的研究与检测。

This paper includes in two sections : the first section is about the research and resolution of the parameters of the Earth 's liquid core free nutation , and the second section involves in the research and detection of the earth free oscillation .

从而求得液体晃动的能量耗散率和系统的章动时间常数。

The dissipative rate of energy and the nutation time constant of the system are obtained .

试验结果表明，球锥贮箱液体晃动可能与卫星章动共振，而使章动发散时间常数剧烈下降。

The test results show that , the liquid sloshing in sphere-cone tanks may resonate with satellite nutation , and nutating divergent time constant will be shapoly reduced .
