摘　　要：介绍了模糊数学中的基本概念、隶属函数及模糊评判的基本理论，并首次提出将模糊数学的理论知识、分析方法与人工智能基本理论相结合，并借助于计算机完成机械工程材料的选择，从而使机械工程材料选择更为科学、更为简单。本文还对此方法进行了实例验证，其效果良好，设计者只需输入工作要求，便可以确定出欲选材料的优先次序。The paper gives an account of the basic theory of fuzzy mathematics,such as its basic concept, subordinate function and fuzzy determination, and for the first time proposes that by means of computer technology, the theory and analytical method of fuzzy mathematics and the basic theory of artificial intelligence are combined for the material selation in mechanical engineering so as to make the material selection more scientific and simplified. The method is verified with examples and proved to be effective: when the designer inputs his work requirements into the computer, the material selection will be automaticaliy completed.
