摘要
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。本文论述基本星表和天文常数变动后，对1953－1961年期间中国地极坐标系统的影响，结果表明星表系统差对地极坐标的最大影响约0．″02，章动系列变动的最大影响约0．″02，光行差常数变动的最大影响为0．″1。
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. In this pa-per the influence of the changes of the fundamental catalogue and the astronomi-cal constants on the Chinese polar coordinates is discussed. The results show that the maximum effects of the systematic corrections of the catalogue are of about 0'.02 in the polar coordinates. The maximum effects of both nutation series and aberration are of about 0'.01 and 0'.01 respectively .
