| 摘 要： | 本文对ＬＬＭＣ＋ＣＣＤ仪器系统的误差理论进行了综合性的探讨。文中所涉及的误差主要来自两方面：其一是来自仪器系统本身的误差，其二是来自仪器系统以外的误差。论文的第一章对ＣＣＤ器件的特性及其在天文学上的应用作了扼要介绍；第二章阐述了低纬子午环配备ＣＣＤ的观测方法，还简述了低纬子午环的结构及观测原理；第三章对十七种不同类型误差的测定或消除方法作了详尽的探讨和分析；第四章推导了星径曲率改正；第五章对小角度天体测量技术和大角度天体测量技术进行了评估。

| Abstract: | The theory on errors from the telescope of LLMC CCD is extensively discussed in this dissertation. The errors to be mentioned are from both inside and outside the telescope itself. The characteristics of CCD system and its applications in astronomy is largely introduced in the first chapter. The observational principles of the LLMC CCD are chiefly given in the second chapter, in which the observational principles and frames of LLMC are also presented. In chapter three, The author discusses 17 different kinds of errors,presenting the corresponding methods of determination and elimination. In chapter four, the formulae for various kinds of curvature correction are derived. Finally small angle astrometric technology and large angle astrometric technology are reviewed in chapter five. |
