我国著名数学家徐利治教授在他的专著《数学抽象方法和抽象度分析法》中提出了“弱抽象”和“强抽象”的概念 .数学概念的弱抽象又称“扩张式抽象” ,即从原型中选取某一特征加以抽象 ,从而获得比原结构更广的结构 ,使原结构成为后者的特例 .我认为 ,数学概念的弱抽象对指导高 Professor Xu Lizhi, a famous Chinese mathematician, put forward the concepts of “weak abstraction” and “strong abstraction” in his monograph “Mathematical Abstract Method and Abstract Degree Analysis Method.” The weak abstraction of mathematical concepts is also called “expanded abstraction”. Selecting a feature from the prototype abstracts it to obtain a wider structure than the original structure, making the original structure a special case of the latter. I believe that the weak abstraction of the mathematical concept is high
