实测大气折射值的新方法

A New Method for the Measurement of the Atmospheric Refraction

简单评述了现有各种版本的大气折射表所依据的理论基础和编制方法,指出了实测大气折射值、建立随地形而异的实测大气折射模型的必要性和应具备的基本条件;在分析了长期以来不能直接测定大气折射值的原因后,介绍了一种在不同方向精确测定大气折射值和建立观测点大气折射模型的新方法,以及所依赖的观测仪器具备的特性,最后给出了用实测数据建立的本地大气折射模型。

In this paper,we comment the theoretic basis and the compiled means of many atmospheric refraction versions.And we draw a conclusion that it is necessary to actually measure the values of the atmospheric refraction and to establish the atmospheric refraction model.This method must fit four strict conditions.Our instrument can just satisfy such conditions.We introduce a method to accurately measure the values of the atmospheric refraction in different directions.At last,a plan is brought forward to establish accuracy atmospheric refraction model in different directions.It is based on different locations and different circumstance conditions.
