夹逼法是一种较为典型的解题方法,它常常用于解决与正整数有关的一些命题.其基本思想是:以一定的限定条件为依据,对所研究的对象进行考察,先估计研究对象的存在范围,这样“可能”的对象被减少,符合条件的对象也就变得易于探求,最后得到我们所需要的结果. The clamp force method is a relatively typical problem solving method. It is often used to solve some propositions related to positive integers. Its basic idea is: based on a certain limited condition, the object to be studied is examined and the research is first evaluated. The scope of the existence of the object, so that the “possible” object is reduced, and the object that meets the condition becomes easy to search, and finally we get the result we need.
