摘要
大气垂直折光是平原地区影响光电三角高程精度的主要因素。本文根据实验结果对低视线三角高程测量中大气垂直折光的影响规律,作了初步的定性分析;并对低视线三角高程的应用,提出了探索的看法。
Vertical atmospheric refraction is the main facteor that influence the accuracy of the E. D. M trigonometric leveling in plainregion. This essay makes preliminary qualitalive study on reflection law of vertical atmospheric refraction on low-sight trigonometric levelings;Mean-while it raises some view-points for studing on atilisation of low-sight frigonometric leveling.
