| 摘 要： | 中介逻辑是一种区分矛盾否定与对立否定、肯定一些对立知识间存在中介对象的逻辑系统。基于中介谓词逻辑描述模糊知识，合理修改与或图，将每一谓词表达式视为状态结点，把逻辑规则集合表示为状态搜索空间。在传统与或图搜索算法的基础上，修改启发函数，将模糊知识的推理问题转化为状态空间中的搜索问题，并给出了一种否定信息的处理方法。

| Abstract: | Medium logic is a kind of logic system which differentiates contradiction from opposition,and affirms that there exists medium between some opposite information.Based on medium predicate Logic,the paper represents fuzzy knowledge,modifies andor graph with reason,regards every predication expression as state node to convert logic formulary into searching space.Then the heuristic function of traditional searching method of and-or graph is modified in order to treat fuzzy reasoning problem as problem of search... |

| Keywords: | medium logic fuzzy knowledge representation state space and-or graph heuristic function negative information |
