摘　　要：根据原中国科学院陕西天文台 (CSAO) (现已更名为中国科学院国家授时中心 )与俄罗斯东西伯利亚物理技术和无线电测量研究所 (VSNIIFTRI)之间签定的科学合作协议 ,陕西天文台光电等高仪 1型在伊尔库茨克进行了为期近 5年的星表观测。根据这些高精度的观测资料共编算出包括 81 7颗星的无赤纬盲区的等高仪星表 (其中首批 2 0 0颗已在欧洲《Astronomy&Astrophysics》上发表 )和 2 2颗射电星的光学位置表 ,后者在本文中给出。此外 ,这几年的测时测纬资料还同时发往莫斯科 ,参加俄罗斯的地球定向参数 (EOP—earthorientationparameters)The observation of star position for catalogue compiling had been made in Irkutsk for 5 years with the Chinese photoelectric astrolabe Mark-1 according to the agreement of scientific cooperation between CSAO and VS NIITRI.This cooperation has taken the advantage of combination of the large zenith distance (45°) of almucantar for the astrolabe Mark-1 with the high latitude(52°)for Irkutsk,which could eliminate the blind zone existing in declination measurements for all the astrolabe catalogues.Based on the cooperation,a star catalogue containing positions of 817 stars had been completed;besides,the positions of 22 radio stars had been measured precisely in both right ascension and declination,which are given in this paper.
