某些数学问题中所出现的各个元素的地位 是不平衡的,其中的某个极端元素或个别元素的 极端状态往往具有优先于其它元素的特殊性质, 而这又恰好为解题提供了突破口.从极端元素入 手,进而简捷地解决问题,这就是通常所说的极 端化原理. 使用极端化原理的关键在于抓住问题的极 The status of each element that appears in some mathematical problems is unbalanced, in which the extreme state of an extreme element or individual element often has special properties that take precedence over other elements, which in turn provide a breakthrough point for problem solving. Starting from the extreme elements and then simply solving the problem, this is the so-called principle of extremeization. The key to using the principle of polarisation is to grasp the pole of the problem.
