摘　　要：根据西北工业大学出版社出版的《数字电子技术常见题型及解析》中的一题目 ,总结了变量之异或式及变量之异或非式在卡诺图上的排列规律 ,对于卡诺图中有 2 r- 1 个“1”值格呈对角排列时直接写出其异或形式的方法从两个角度作了解释 .Based on the subject from the book published by North-West Industry Technology University Regular Subjects Analysis and Practice for Digital Electrical Technology . This paper summarized the regular ordering pattern in Karnaugh map of the exclusive OR-switching function and its reverse of all variables. We explain the method of directly writing out the exclusive OR expression of the function directly when 2\+\{r-1\} number of '1' value is in order in diagonal line from two angles.

关 键 词：逻辑函数 卡诺图 异或式
