摘　　要：首先提出了模糊逻辑和多值逻辑的相似性 ,并建立了三值逻辑函数文字运算和模糊逻辑函数短语的对应关系 ,进而提出了从三值逻辑函数的规范展开式求得模糊逻辑函数规范展开式的算法 ,并用该算法对几个模糊逻辑函数实例进行了规范展开 .实例操作表明 ,该算法具有简单、规范、方便快捷的特点 ,是获得模糊逻辑函数规范展开式的一种有效的方法 .The similarities between fuzzy logic(FL) and multi-valued logic are discussed. The corresponding relationship between the literals of the ternary value logic(TVL) function and the phrases of the FL function was established and an algorithm was proposed for finding the canonical form of the FL function using the method of finding that of the TVL function. Using the algorithm, several canonical forms of the FL function were found, and operational examples showed that the algorithm has the characteristics of simple, normative and shortcut, and is an effective method for finding the canonical form of the FL function

关 键 词：多值逻辑 模糊逻辑 规模展开式
