摘要

讨论了Oppolzer项对确定纬度变化、极运动和赤纬的影响。我们建议将天极定义为自转轴的交点，并根据日月极运动与天球进行校正。或者近似地定义为自转轴的日平均方向与天球的交点。

New problems in nutation calculation

The effects of Oppolzer terms on the determination of latitude variation, polar motion and declination are discussed. We suggest that the celestial pole may be defined as the intersection of the rotation axis, corrected for the lunisolar polar motion with the celestial sphere. Or approximately, it may be defined as the intersection of the diurnal mean direction of rotation axis with the celestial sphere.
