摘要
众所周知,边角网平差时应进行方差分量估计,以使观测权趋于合理。本文详细地推导了附有条件的间接平差的方差分量估计公式,给出了算例,并得出一些结论。
It is known that during the side and angle adjustment of networks, it is necessary to do the variance components estimation to make the weights of observations rational. This paper derives minutely the formulae of variance components estimation in conditional indirect adjustment. It gives examples of calculation and d(?)ws some conclusions.
