摘　　要：IFScom是一种区分矛盾否定关系、对立否定关系和中介否定关系的模糊集。针对模糊集IF-Scom在应用中的特点,对其中介否定算子作了进一步改进,使得中介否定集的λ-区间函数从[1-λ,1]扩充到[0,1],其分段比例函数的增减性更符合实际。在此基础上给出了λ-中介否定集在模糊入侵检测中的应用,仿真实验表明该中介否定集在模糊知识的"否定"区分、处理和推理上是有效的。IFScom is a fuzzy set used to differentiate three negations： contradictory negation,opposite negation and medium negation. According to the characteristics of fuzzy set IFScom in the application, the midium negation operator was improved. The new interval function extending to [0, 1]from [1-λ,λ], and the proportion of the increase or decrease of piecewise function is more practical. Based on which, the medium negation set and it’s its application on fuzzy intrusion detection model is proposed. It is proved effective through the simulation experiments.
