摘　　要：本文从测量平差精度评定的求解协因数阵的过程中,寻找了一种有关协因数阵的简便算法,此算法的特点在于从已知的解法中,提炼出一种便于理解和记忆的方法,从经典的平差解答中找出规律,从而避免了去死记硬背复杂的结论。本文针对提出的简便算法,在条件平差、间接平差、附参数的条件平差和附限制条件的间接平差中通过验证,结果是正确的。Based on the measurement accuracy of the adjustment process for the coordmated factor mamx, a slmple algorithm for the solution has been found. The feature of this algorithm is to extract an easily comprehensible and memorable method from the known solutions, thus avoiding the complexity of the conclusions to rote. This simple algorithm has been tested in condition adjustment, indirect adjustment, condition adjustment with parameters and report limiting condition.
