摘要
本文引入ＰＯ—半群，ＰＯ－半群的滤子，弱交换等概念，讨论了弱交换性对ＰＯ—半群结构的影响，得到ＰＯ—半群满足弱交换性的一个充要条件．
In this paper, we introduce the concepts of filter of a po-semigroup, of weakly commutativity, we discuss the effect of po-semigroups of weakly commutativity on it's structure. Get a ample and essential condition which po-semigrorp satisfy weakly commutativity.
