对一测边网条件方程有误的分析

Analysis of A Trilateration Net's Condition Equation with Errors

对测量普遍使用的测边网中条件平差问题进行了分析 ,比较了两种条件的方程式 ,指出了一个错误条件方程式的错误原因是一个没有度量标准的式子 。

The condition surveying problem in a trilateration Net commonly used in measurement is analysed,two types of conditional equations compared,then it is poined out that one of them is wrong.The reason is there is no measurement standard,which is proved by an example.
