摘　　要：毕竟正则半群是一类重要的广义正则半群,利用半群模糊同余的概念,获得了毕竟正则半群上群同余的一些新刻画,并给出了毕竟纯整半群上一个模糊同余为模糊群同余的充要条件.Eventually regular semigroup is a class of important generalized regular semigroups.In this paper,some new characterizations of the group congruence on such semigroup by means of the notion of a fuzzy congruence on semigroups are obtained.Finally,sufficient and necessary conditions for a fuzzy congruence on an eventually orthodox semigroup to be a fuzzy group congruence are given.

关 键 词：毕竟正则半群 模糊同余 模糊群同余 毕竟纯整半群
