| 摘 要： | 极移中Chandler摆动出现的双频现象，一直以来为许多学者所关注。推导了基于Chandler摆动双频的极移确定项模型，并采用该模型对极移确定项进行了拟合。与仅采用单频进行确定项拟合的对比表明，利用双频能取得更理想的结果。

| Abstract: | Many researchers have been interested in whether Chandler Wobble exists two-frequency. So, two-frequency mod- el of the Polar motion＇ s sure part is deduced in this paper, based on which the Polar motion＇ s sure part is matched. The re- sult of two-frequency is compared with that of one-frequency of Chandler Wobble, which shows that better results can be got by using two-frequency of Chandler Wobble to match. |
