对一个不规则形状的普通石块,怎样计算它的体积呢?如果从石块的形体结构出发,联想所学过的简单几何体的体积公式,确实难以计算.但如果借用一个量杯(能够容下这个石块),把石块放入,再加入水,然后取出石块,则计算出那个下降的水的体积,就是所求石块的体积.像这种避开局部分析,从宏观上研究问题的整体形式、整体结构、整体特征,从而对问题进行整体处理的思想,称为整体思想.下面,就初中数学中整体思想的表现形式和运用举例加以介绍. How to calculate the volume of an ordinary stone with an irregular shape? If the volume structure of a simple geometric body from the block structure, Lenovo learned the volume formula of a simple geometry really difficult to calculate, but if you borrow a measuring cup This stone), the stones into, and then add water, and then remove the stone, then calculate the volume of water that is descending, is the size of the stone sought.Such as to avoid the local analysis, macroscopically The whole form of the problem, the overall structure, the overall characteristics, and thus the overall treatment of the idea of ​​the problem, known as the overall idea of ​​junior high school mathematics below, the overall idea of ​​the form and use of examples to be introduced.
