摘　　要：本文研究了１９６２—１９８６年ＪＹＤ_（１９６８．０）地极坐标均匀中星表系统差，章动系列的变动和光行差常数变动的影响，并将经过改正后的ＪＹＤ_（１９６８．０）地极坐标系统和ＢＩＨ系统作了比较。Since 1984s the FK5 fundamental catalogue and the new astronomical constants were used in the astronomical calculations. Due to these changes they will directly effect the coordinates of pole determined by the observationalresults with the optical instruments. for example the zenith telescope. In this paper the influences of the changes of fundamental catalogue and astronomical constants on the coordinates of pole obtained by meas of the international Latitude Service (ILS) were discussed. The results show that (1) the maximum effects of the systematic differences of the catalogue for the coordinates of pole are about -0. 006' and - 0. 004' on the x-component and y-component respectively:(2) the maximum fluctuations of the changes of nutation series are 0. 012' and 0. 010' on the x-component and y-component respectively.
