| 摘 要： | 通过对经纬仪横轴本身不水平和由于竖轴不竖直导致横轴不水平2方面分析横轴倾斜对竖直角观测的影响,推出相应的公式.并通过实验数据得出,通过水准管安置经纬仪,由于横轴倾斜角非常小,不必考虑横轴倾斜对竖直角观测的影响.

| Abstract: | The paper analyzed the lateral axis error impact on vertical angle observation,and derived the formulas separately according to theodolite lateral axis itself inclination error and theodolite lateral axis inclination error induced by vertical axis inclination error.The experiment data proved that the vertical angle error can be ignored if the theodolite is settled by level tube. |
