摘要
本文推导了在附有限制条件的条件平差中,顾及起始数据误差影响时,计算单位权中误差和平差值函数的方差的公式。给出了计算实例,并由此引出了其他平差模型的相应计算公式。
This paper derives the formulas for computing the mean square error of unit weight and the weight reciproeal of the function of adjusted values in the condition adjustment with constraints when the influonce of the initial data errors is considered. A computing example is also given to illustrate the formulas. In addition, the corresponding formulas in some other adjustment models are discussed.
