摘要
章动观测值与理论值之间的差异提示人们，当前所使用的Ｗａｈｒ章动理论中存在一些未知的效应。本文利用ＶＬＢＩ观测资料和测纬资料，对主要章动项振幅和自由核章动周期进行了检验。实际计算表明，根据ＶＬＢＩ资料和测纬资料的处理，所得到的自由核章动周期是相同的。
It is proved that some unknown effieciency exists in Wahr nutation theory by the difference of the nutation observations and theory values. In this paper. making use of the observations of VLBI and Latitude. we test main nutation amplitude and free core nutation cycle. The actual calculation have proved that the free core nutation cycle obtainedby VLBI date and Lati tude date are showing no difference.
