摘　　要：在模糊知识中存在三种不同的否定,即矛盾否定、对立否定和中介否定,基于中介谓词逻辑MF与其无穷值语义解释Φ,研究了模糊知识及其三种否定的表示与推理,并在一个金融投资决策实例中进行了应用。引入了一种新的与Φ中参数λ相关的模糊产生式规则,讨论了实例中的模糊知识及其三种不同否定的推理算法与实现。Three kinds of negations in fuzzy knowledge are proposed, namely contradictory negation, opposite ne-gation and medium negation. Based on the medium predicate logic MF and the infinite-valued semantic interpretation Ф of ME the representation and reasoning on fuzzy knowledge and three kinds of negations are investigated. To show applicability of the results, an example which assists decision making in the financial investment is discussed. Concretely, the paper introduces a new fuzzy production rule which threshold value relates to 2 in Ф, and discusses the reasoning and realization about fuzzy knowledge and three kinds of negations in example.
