“放缩法”就是将问题中的某些量放大或缩小,使各量之间的关系十分清晰地显露出来.由于放缩变换不受公式、法则、定理的限制,因此没有现成的模式可套,一般可根据题目中的字母(数量)的特征而定,必要时可插入一个(或部分)中间整式(量)作为媒介并应用相关知识才能使问题得到解决. “Scaling Law ” is to enlarge or reduce some of the problems in the problem, so that the relationship between the amount of very clearly revealed.As scaling is not limited by formulas, rules, theorems, so there is no ready-made Modes can be set, generally based on the characteristics of the letter (s) in the title, inserting one (or some) of the intermediate integers as a medium and applying relevant knowledge, if necessary, to solve the problem.
