本文从理论上推导了约束条件为参数平差的相关观测值的一次范数最小平差（Ｌ１平差）模型，并对不同的数学实例进行了试算。结果表明，Ｌ１平差具有较好的抗粗差能力。
In this paper, we first derive a model of the minimum adjustment (L1 adjustment) of the norm for which the constraint is the correlative parameter of the parameter adjustment, and try the different mathematical examples. The results show that the L1 adjustment has better anti-gross error ability.
