摘要
秩亏水准网按附加条件法平差的法方程系数阵和参数先验权阵具有对称特性，利用此特性和水准网附加矩阵的特殊形式，以及文献［２］中给出的线性方程组未知数及其函数、系数阵逆阵计算的一维公式，可导出秩亏水准网按附加条件法平差的一维平差计算公式，使秩亏水准网平差计算和程序设计简单易行。
The coefficient matrix of normal equation and parameter prior weight matrix of rank defect Leveling network accrding to adjustment with constraint have symmetry,with this property, the special form for additional matrixes of coefficient matrix. A dimensional adjustment formula can be inferred for rank defect leveling networks, it makes the adjustment calculation and programming of rank defect leveing networks easy.
