The relation between the error of nutationconstant and the corrections of declinations, proper motions calculated by chain method is analysed, and the method to correct this effect is considered.
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 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.
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 stability criteria and the decay time constant of the nutation damping are obtained in an analytical form, by which the degree of the attitude stability can bd evaluated.
