大气折光对三角高程测量的影响及精度分析

摘要

The article from the analysis of atmospheric refraction in EDM trigonometric leveling measurement influence proceed with,put forward to reduce the influence of atmospheric refractivity measures should be adopted,to improve the accuracy of triangulation has a certain practical value.%本文从分析大气折光对三角高程测量的影响入手,提出减小大气折光对高差影响应采取的措施,对提高三角高程测量的精度有一定的使用价值。
