摘要
由连续数学与离散数学中相关概念 ,引出函数、映射与二元关系。以映射作为函数与二元关系的纽带 ,总结三者之间的联系与区别 ,以及运算和应用中的不同特点。
This paper analyzes the correlation conception of continuum math and scatter math,and expatiates the conceptions of function,mapping and binary relation.The contact and difference between them and the features in the operation and application are also summarized.
