| 摘 要： | 讨论了“水准式光电测距三角高程的再认识与思考”一文的若干问题,分析了传统EDM三角高程测量高差计算公式的严密性问题,以实例证明了利用地球平均半径计算球气差改正数产生的误差可以忽略不计,说明了水准式光电测距三角高程高差计算公式不存在多值解问题。

| Abstract: | It discusses the issue about "New understanding on the EDM trigonometric leveling of leveling type",analyzes the rigor of the formula about traditional trigonometric leveling,and proves that the error of the earth curvature of calculating by mean radius of earth curvature in surveying can be ignored,and explains that the EDM trigonometric leveling of leveling type serves no multiresolution. |
