| 摘 要： | 大气折光差是精密水准测量系统误差的主要来源之一,必须设法予以削减。本文在分析现有水准折光改正方法的基础上,导出了一种基于水准视线折光角的改正模型。该模型具有跟经典的库卡梅基模型大致相同的改正精度,但适用性更强。

| Abstract: | It is necessary to reduce the error due to atmospheric refraction that is one of the main systematic errors in precise leveling.Based on the analysis of present methods for atmospheric refraction correction,a new correction model is put forward based on the refraction angle of the line of sight.This model is as accurate as classical Kukkamaki's model but with wider applications. |
