导线平差取权方法探讨及自动定权的条件平差方法

Discussion on the weight Selection of Traverse Adjustment and Its Conditional Adjustment method.

本文应用方差估算的基本理论,利用导线边、角改正数本身的大小,或利用导线坐标闭合差本身的大小来确定边、角的权,使平差成果及精度估计得到合理结果,且选权有唯一性,计算速度快。

Based on the theory of variance estimate, the corrected size of both traverse side and angle itself or the size of closing error of traverse coordinate itself is used to determine the weights so that the adjustment and accuracy estimation can be reasonable and weight selection be of uniqueness.
