摘要
本文运用数理统计学原理分析了南通市一级导线网(B区)单位权中误差偏大的原因;从概率的角度得出单位权中误差偏大的主要因素为:观测方向中有显著的系统误差。
This paper analysis the reason why the middle error of unit wei- ght in first class traverse of Nan Tong City (B area) is bigger with the principle of mathematic statistics; we realize that the main factor of the bigger middle error of unit weight is that there is the remarkable systematic error in the direction of observation from viewpoint of probability.
