摘要
本文通过对两种附有限定条件的间接平差公式进行分析,把它们应用于不同的导线网中。在应用过程中,分析它们的差异、对比它们的性能指标。最后,得出在附有限定条件的间接平差问题中应该尽量采用法方程整体求逆的方式进行计算的结论。在作者编写的通用导线网平差软件中应用了此方法,取得了良好的效果。
On the analysis of two indirect adjustment formulas with restrictive condition in traverse network,these two formulas are applied to the different traverse networks,and then their difference and performance characters are presented.Lastly,the conclusion is obtained which the method of whole inverse matrix method should be used in the indirect adjustment.In the generic adjustment software for traverse network written by the authors,the indirect adjustment method is applied and good results are obtained.
