摘要
本文应用矩阵代数理论，导出了在最小二乘平差中改正数Ｖ的不变住，精度指标及可靠性指标的一致住，从而提出了大型网平差中，当ｔｒ时，采用系数阵Ａ来计算多余观测分量ｒｉ，体现了可减少计算工作量，节省计算机内存等优越性．
By applying the matrix algebraic theory, the nonchange ability for correction V in the least Square ed justment, and the consistency for the precision and the raliability are infered in the peper. Hence if tr in a large net adjustment,the coefficient matrix A may be utilized to calculate the abundant observation vectors ri,so the caculation work can be reduced and the computer memoby can be saved, as well.
