我国古代数学可谓博大精深 ,其中有许多光辉的数学思想与方法值得我们学习 .比如 ,著名的祖 日恒原理 ,即“幂势既同 ,则积不容异” ,意思是 ,介于两平行平面之间的两个几何体 ,如果被任一平面所截得的两个截面面积都相等 ,则这两个几何体的体积必相等 .用之可将不规则几何体转 Ancient Chinese mathematics can be described as profound and profound, among which there are many glorious mathematical ideas and methods that are worth our studying. For example, the well-known Zu Riheng principle, that is, “power and potential are both identical, the product can not tolerate differences”, meaning that it is between two parallel planes. The two geometries between the two geometries, if the area of ​​the two cross-sections intercepted by any plane are equal, the volume of the two geometries must be equal. It can be used to transfer irregular geometries.
