这些数值可以用来检验用新天文常数计算的时纬观测结果。

Using these results , the determination of time and latitude with the new astronomical constant can be studied further .

1984年开始，天文计算中采用FK5基本星表和新天文常数，这些变动直接影响了经典光学仪器观测确定的地极坐标。

The FK5 fundamental catalogue and the new astronomical constants have been used in the astronomical calculation since 1984 . These changes will directly effect the results of the polar coordinates with classical optical instruments .
