| 摘 要： | 分析了经纬仪水平测角时的误差组成，为了更精细地分离各误差成份提出了
谱分析法，并对引起测角误差的主要分量进行了误差修正。实际测量数据的分析表明，该方
法与传统的一次水平测角极限误差相比，可以获取更详细的误差，并可大大减小经纬仪使用时的测量不确定度。

| Abstract: | The composition of errors during the horizontal angle-measurement of theodolite is analyzed in this paper. The spectrum analysis is proposed for identifying the variant errors more precisely. Error correction is introduced for the main component of the errors caused in measuring the horizontal angle. The result of experimental data analysis indicates that the method of spectrum analysis and error correction can get more detailed error information and reduce the uncertainty of measurement greatly during the measurement of theodolite, comparing with the thaditional method of finite error for single horizontal angle-measurement |
