摘　　要：首先给出了半环的L-模糊理想同态的定义,在此基础上较系统地讨论了半环的L-模糊理想范畴的性质,证明了此范畴是半环范畴上的一个拓扑结构,并探讨了其中的等子、拉回和乘积等性质.另一方面,给出了半环的L-模糊理想范畴的逆系统的定义,建立了半环的L-模糊理想范畴中逆系统的逆极限结构.特别是在引入两个逆系统之间映射的基础上,得到了两个逆系统的逆极限之间的极限映射.The concept of L-fuzzy ideals of semirings is first introduced in this paper. Based on this new concept, some properties of the category of L-fuzzy ideal of semirings are investigated, the result that the category of L-fuzzy ideals of semirings is a topological construct on the category of semirings is also proved. Meanwhile, the equalizer, pullback and product are all discussed. On the other hand, the notion of inverse systems of category of L-fuzzy ideals of semirings is proposed and the inverse limit of the category of L-fuzzy ideals of semirings is constructed. Particularly, the limit mapping has been obtained by means of presenting the mapping between two inverse systems.
