摘　　要：以地震科学考察项目、鄂尔多斯项目、大华北地区项目区域精密水准测量成果为依据,分析数字水准仪在实际测量中的主要误差来源及消除或者减弱的技术措施和方法,重点探讨空气相对湿度对成果精度的影响。分析发现主流数字水准仪测量成果精度在一定程度上受自然条件中的湿度影响,但目前还没找到合适技术手段去削弱,以待后续研究。Based on the regional precision leveling survey results of seismic scientific investigation project,Or⁃dos project and Great North China project,this paper analyzes the main error sources of digital level in actual measurement and the technical measures and methods to eliminate or weaken the error,and focuses on the in⁃fluence of air relative humidity on the accuracy of the results.Through the study,it is found that the accuracy of measurement results of mainstream digital level is affected by humidity in natural conditions to a certain ex⁃tent,but appropriate technical means have not been found to eliminate it,waiting for subsequent research.
