1、放缩法证明不等式一、放缩法原理为了证明不等式BA，我们可以找一个或多个中间变量C 作比较，即若能判定BC,CA同时成立，那么BA显然正确。所谓“放”即把A 放大到 C,再把 C 放大到B；反之，由B 缩小经过C 而变到 A,则称为“缩”，统称为放缩法。放缩是一种技巧性较强的不等变形，必须时刻注意放缩的跨度，做到“放不能过头，缩不能不及”。二、常见的放缩法技巧、基本不等式、柯西不等式、排序不等式放缩2、糖水不等式放缩：)ba,0m(mambab.3、添（减）项放缩4、先放缩，后裂项（或先裂项再放缩）5、逐项放大或缩小：)1n(n1n1)1n(n1221n2)1n(nn)12)(32(1)12(1
