模糊逻辑命题演算系统L^*在模糊逻辑与模糊推理的结合研究中得到了成功的应用。本文进一步研究系统L^*的语法结构,得到了一些有趣的新结果,特别是给出了它的一个简化形式,并证明了这个简化公理系统的独立性。
The formal system L^* is an important fuzzy propositional calculus system, and it has been successfully applied to researchers connecting fuzzy logic and fuzzy reasoning. This paper further discusses syntactic structure of the system L^*, some new results are revealed. In particular, a simplified version of the system is given, and the independence of this version is also proved.
