摘要
本文根据水准面、似大地水准面、参考椭球面、高程异常、垂线偏差与正常高之间的关系，推导出了新的普通三角高程测量及光电测距三角高程测量的精密计算公式，并对新公式进行了初步的实验验证。
The conclusions in this paper are based on relation among level surface.quasi-geoid, surface of reference ellipsoid, height anomaly, deflection of the vertical andnormal height. New accurate formulas of ordinary trigonometric leveling and EDM -height measurement have been set up. The preliminary test for new formulas has beenconducted.
