| 摘 要： | 自七十年代后期起，中国的４架光电等高仪就开始注重于旨在改进基本星表系统的观测．这４架光电等高仪均实现了现代化改造：实现全自动化操作和采用光子计数记录，这使得仪器能通宵达旦地工作，效率倍增．近年来用中国光电等高仪的观测已经编算出几部等高仪星表，其两个坐标（α和δ）的精度都很好，极限三等可达１１ｍ以上．将来这４架光电等高仪和即将用ＣＣＤ装备的Ⅲ型光电等高仪将会对基本天体测量做出更大贡献．

| Abstract: | The. four Chinese Photoelectric Astrolabes (PAs) have been concentrated on observations for star catalogues since the late 1970s. The four PAs have been modernized with automation and photon counting detector, which have made the PAs operate automatically and effciently, Several astrolabe catalogues have been completed or compiled in China with good precision both in Q and S, and faint limiting magnitude up to 11.3. In the future,the four PAs and a new PA (Mark M ) equipped with CCD detector would contribute more to fundamental astrometry. |
