摘　　要：从概括平差函数模型出发，利用分组平差理论及相关最小二乘原理，导出了分组平差模型的平差计算及精度评定公式．概括函数模型的分组平差的平差计算和精度评价公式适应于所有的分组平差方法．In this paper starting from the general functional model, the universal adjustment formulae and the universal formulae for accuracy evaluation have been derived by using the theory of successive adjustment and the principle of correlative least square. These formulae are given adopting all least squares adjustment models. For example, when C =0, eq(1) becomes the functional model of condition adjustment with unknown parameters; when A =-I, eq(1) becomes the functional model of parameter adjustment with constraint among the parameters. Therefore, references and are special cases of the paper.
