摘要
The aim of this paper is to determine the subset of an ordered semigroup S that can serve as a class of some regular congruences on S. The results on semigroups without order given in [5] can be obtained as consequences.
本文的目的是给出一个序半群的子集能成为某个正则同余的同余类的刻画，同时我们可以容易看出［５］中的关于一般半群（没有序关系）的相应的结论仅是本文的结论的应用．
