随着科技的进步,如今大型桥梁、地铁等都是采用分段施工、整体合拢的“组装”建造模式.其实,在解决数学问题时,尤其是证明那些外形结构相似的对称(或对称轮换)不等式,也可以借鉴上述模式:先精心分割成对称的局部,紧盯整体的目标和方向,最后有机融合于一体,我们把这种方法称为“组装法”.1.几个案例 With the progress of science and technology, large-scale bridges and subways nowadays are all constructed in a segmented way and are closed together. In fact, when solving mathematical problems, it is especially necessary to prove that symmetrical (or symmetrical) Rotation) inequality, you can also learn from the above model: first carefully divided into symmetrical part, keeping an eye on the overall goal and direction, and finally organic integration, we call this method “assembly method ”.
