三角高差严密公式的讨论

Discussion on the precise formula for the trigonometrical height difference

本文通过公式论证和数字验算,探讨了大气垂直折光、曲率半径和垂线偏差对三角高差的影响,对三维网中三角高差的严密公式进行了讨论。

This paper makes an approach to the influence of atmosphere plumb retraction,radius of curvature and divation of plumb on the trigonometrical height difference by means of formula demonstration and numerical computation,and discusses the precise formula for the trigonometrical height difference.
