为学生能在网络上随时随地学习卡诺图化简，提高自主学习的质量，在 ASP ．NET 环境下，利用rapheal框架实现了卡诺图自动化简逻辑函数系统．系统能够对任意输入的三至五变量的逻辑表达式及指定的无关项使用卡诺图化简法进行化简，并且在网页上按步骤展示其化简过程．输入表达式的语法验证采用改进的算法优先分析法，化简过程采用广度优先搜索模仿人工搜索卡诺圈的过程，网页作图由rapheal框架实现．测试结果表明，系统可在常用浏览器下正常运行，可正确的按步骤展示卡诺图化简逻辑函数的过程．%For students can learning Karnaugh map Simplification anytime ,anyw here on the net‐work ,improve the quality of self‐learning ,in ASP .NET environment ,the use rapheal framework to a‐chieve a Automatic Karnaugh map simple logic function system ,system use the Karnaugh map simplifi‐cation for any input three to five variable logical expressions and don′t care terms Simplification ,and show the process step by step on the page .Syntax validation the input expression using the improved al‐gorithm of priority analysis method ,simplification process using breadth‐first search imitate the process of manual search Karnaugh circle ,drawing on the page implemented by rapheal framework .The test re‐sults show that the system can operate normally in common brow sers ,correct to show Simplification of process logic functions step by step .
