摘要
经文中证明 ,秩亏自由网平差参数估值是有偏的这一结论不成立 ,同时通过讨论平差基准与平差参数真值之间的关系 ,证明秩亏自由网平差参数估值相对于其真值基准是无偏的。
The argument that the estimated values of parameters in rank defect free net adjustment are biased cannot be well justified. On the contrary, based on the relationship between the adjustment atum and the true values of adjustment parameters, is has been proved that the estimated parameter values are unbiased relative to their true value datum.
