给出了中国科学院７ 个天文台站经纬仪静态系统差的测算结果。根据经纬仪的光学和机械构造， 提出一种有１０ 个误差参数的经纬仪静态系统差模型。又根据星表中的恒星沿赤经基本均匀分布的特点， 提出一种快速查找指定恒星的方法。对于《中国天文年历》中所载的１２１８ 颗恒星的星表， 使用这种快速查找方法， 平均只需查找４ 次即可。
The calculation results of the static system of theodolite at seven astronomical stations in Chinese Academy of Sciences are given. According to the optical and mechanical structure of theodolite, a static model of theodolite with 10 error parameters is proposed. Based on the fact that the stars in the catalog are basically evenly distributed along the atria, a method of rapidly finding the specified stars is proposed. For the 1218 star catalogs contained in the “Chinese Astronomical Almanac”, using this quick search method, you only need to find 4 times on average.
