所谓放缩法就是利用不等式的传递性,对照证题目标进行合情合理的放大和缩小的过程,在使用放缩法证题时要注意放和缩的“度”,否则就不能同向传递了,此法既可以单独用来证明不等式,也可以是其他方法证题时的一个重要步骤.下面举例谈谈运用放缩法证题的常见题型.一、“添舍”放缩 The so-called deflation method is the use of inequality transmission, control of the target of the test subject to reasonable and reasonable amplification and reduction process, in the use of scalar law test questions should pay attention to put and shrink the “degree”, otherwise it can not pass in the same direction, This method can be used alone to prove inequality, it can also be an important step in other methods. Here is an example to talk about common questions using the deflation test.
