数与形是数学中的两个最古老,也是最基本的研究对象,它们在一定条件下可以相互转化。中学数学研究的对象可分为两大部分,一部分是数,一部分是形,但数与形是有联系的,这个联系称之为数形结合,或形数结合。我们认为,数形结合主要指的是数与形之间的一一对应关系。数形结合就是把抽象的数学语言、数量关系与直观的几何图形、
Number and form are the two oldest and most basic subjects in mathematics, and under certain conditions they can be transformed into each other. The object of secondary school mathematics research can be divided into two parts, one part is number, one part is shape, but the number is related to shape. This connection is called combination of number or shape. In our opinion, the combination of number and shape mainly refers to the one-to-one correspondence between number and shape. Combination of numbers is the abstract mathematical language, the number of relations with the intuitive geometry,
