客观世界是一个普遍联系的整体,任何事物都不是孤立的存在着,而是通过各种方式与其他事物相互依赖、相互作用、相互制约。数学研究的两类基本对象——数与形,亦是如此。在中职数学教学中,可以把有些数量关系问题转化成图形性质问题或者把有些图形性质问题转化成数量关系问题来研究,即以“形”助“数”或以“数”赋“形”。数形结合的实质就是 The objective world is a whole of universal contact. Nothing exists in isolation. Instead, it interdependence, interaction and mutual restraint with other things in various ways. The same applies to the two basic classes of mathematics - numbers and forms. In mathematics teaching in secondary vocational schools, we can study some quantitative relations into the nature of the graph or the transformation of some graphical nature into the quantitative relation, that is, use “” “Fu ” shape ". The essence of the combination of numbers is
