经纬仪一测回水平方向标准偏差检定方法比较

Methods comparison of testing theodolite one observation set horizontal direction standard deflection

通过对检定经纬仪一测回水平方向标准偏差３种方法的简介、优缺点的比较以及对测试台法和比较法通过实测数据的比较，指出了３种方法中，唯比较法检定精度高，省时省力，能真实可靠地反映经纬仪的综合误差．

This paper elaborates comprehensively on the advantages and disadvantages of the three ways used in testing theodolite's one observation set horizontal direction standard deflection through a brief introduction and a detailed comparison and through actual data gained respectively from the comparative method and the testing platform method. It finally points out that among the three ways the comparative way is the most accurate,the most time saving energy saving and the most reliable in showing a theodolite's comprehensive deflection.
