抽屉原则是由德国数学家狄里克雷最先运用于解决数学问题的,它是组合数学里最基本的原理,又叫鸽笼原理。首先回顾关于抽屉原则的一些基本知识,然后论述抽屉原则在中学数学解题中的应用。
Drawer principle was first applied by the German mathematician Dirichlet to solve mathematical problems, it is the most basic principle in combinatorial mathematics, also known as pigeonhole principle. First of all, I will review some basic knowledge about drawer principle, and then discuss the application of drawer principle in solving mathematical problems in high school.
