| 摘 要： | 以近地层大气垂直折光系数的传统反演方法和理论计算模型为基础，提出了一种可以直接利用对向EDM三角高程测量结果计算往测与返测折光系数的新反演方法。运用该方法时，不需要增加外业工作量，只需通过联合求解传统反演式和理论计算式，便可求得相对可靠的折光系数值，从而有效提高EDM三角高程测量的精度。

| Abstract: | On the basis of the traditional inversion method and the theoretical calculation model of atmospheric vertical refraction coefficient in lowest troposphere, a new inversion method for calculating the refraction coefficients by use of the results of the direct and reversed EDM trigonometric leveling is put forward. Using this method, we can get the reliable value of refraction coefficient and effectively improve the precision of EDM trigonometric leveling only by solving the traditional inversion equation and the theoretical calculation equation jointly, without any extra field-works. |
