摘　　要：从附有未知数的分区条件平差模型出发，探讨了利用虚拟误差方程不组成分区法方程而直接组成未知数的总和法方程进行导线网平差的方法和步骤，研制了相应的应用软件，克服了以往在ＰＣ－１５００或ＰＣ－Ｅ５００机上进行导线测量平差软件解算导线点数量有限，运行速度慢、容易出错。Based on the model of constrained block adjustment, how to conduct the adjustment of a traverse network with ficititious error equations rather than normal equations is discussed in the paper. The adjustment software based on it is also designed and developed, which avoids other related adjustment softwores main defects: Limited number of traverse points, slow calculating rate and interference by people while adjusting.
