摘要
大气折光系数K值是一个很重要的测量参数,但它受地形、温度、气压等外界条件的影响很大。因此,确定一个适合本地区特征的K值十分必要。以大量的实地测量数据为基础,对环抚仙湖西线带状区域的大气折光系数K值进行计算分析,确定了适合当地特征的K值。这样做不仅便于测绘生产和该地区测量工程的实践应用,更有利于测量参数的标准化。
Atmospheric refraction coefficient K is a very important measurement parameters, but it is easily influenced by terrain, temperature, pressure and other external conditions. So, it is necessary to determine the K for the region characteristic. A large number of field measurement datas is based on, the K is calculated and analysed. Finally the K for local characteristics is determined. This is not only convenient for surveying production and practical application of surveying engineering, but also helpful for conducive to the standardization of measurement parameters.
