本文提出了一种新的处理排序偏序集中反链置换f的方法，将单调布尔函数的下单位集移动到其上零点集。对于f的某些已知性质，给出了更简洁、更透明的证明。较详细地讨论了三个链的直积f的轨道。
We present here a new treatment of the permutation f of antichains in ranked posets moving the set of lower units of a monotone Boolean function to the set of its upper zeros. Shorter and more transparent proofs for some known properties of f are presented. The orbits of f for a direct product of three chains are considered in some detail.
