中文摘要：

根据工程研究及发明创新中出现的矛盾问题,提出了基于可拓学的矛盾描述和分析方法,给出了矛盾度、矛盾函数以及转化函数等概念化形式,并构建了工程矛盾的模型.同时,根据工程研究中解决主要矛盾是发明创新的关键这一重要理念,提出了识别主要矛盾的算法——均态划分算法,为计算机智能化处理矛盾给出了一种有效的技术方法.

英文摘要：

Regarding the problems that appeared in the engineering research and innovation, it advances the ways of describing and analyzing contradictions, based on the extenics, presents some concepts of contradiction degree, contradiction function and transformation function, and constructs a model for engi- neering contradiction. At the same time, according to the important idea that solving the main contradic- tion is the key to innovation in the engineering research, it proposes the identification algorithm for the main contradiction--normal partition algorithm, which is an effective technical method for intelligent pro- cessing of contradiction by the computer.
