摘　　要：基于张文修(2001)半群中粗糙理想的概念与性质,本文首先给出Fuzzy半群中点态化强Fuzzy同余关系和Fuzzy粗理想的定义,然后主要讨论了Fuzzy半群中两个非空Fuzzy子集积的Fuzzy粗理想的有关性质,进一步补充和完善了Fuzzy半群中粗糙集理论的数学结构.Basing on the definition of the rough ideal in semigroup and it propertyes in Zhang Wen-xiu （2001）. The definition of the strong fuzzy congruence on fuzzy point and the fuzzy rough ideal in fuzzy semigroups are given, and the main product propertyes of fuzzy rough ideals of two non empty fuzzy subsets in fuzzy semigroup are discussed in this paper. So, the mathematical structure of the rough sets theory in fuzzy semigroups are completed and perfected.
