| 摘 要： | 本文介绍1.26米红外望远镜出厂后的主要误差,用谐波分析法分离望远镜的各项主要误差(2~m显示误差,4~m17~5短周期跟踪误差以及长周期跟踪误差等),讨论误差产生原因,计算由这些原因引起的误差理论值,并与实测值进行比较,分析其对望远镜使用精度的影响,叙述消除误差的方法及实际效果。

| Abstract: | This article expounds some main errors of the 1.26 m Infrared Telescope of the Beijing Astronomical Observatory after its installation and tries to separate each of them (2m displaying error, 4m17s short-period as well as long-period tracking errors, etc.) by harmonic analysis. Then it discusses the main factors causing them, calculates their theoretical values and compares these with the practical measurements, analyses the effects of the errors on the precision of the telescope and introduces methods to eliminate the errors and their performance. |
