化归思想是中学数学中常用的解题思想。从化归思想的定义可以看出,在化归思想过程中,包括三个基本的要素:化归对象、化归目标和化归方法。化归对象就是我们在原问题中需要转化的成分;化归目标就是我们在化归过程中希望能够达到的目标;而化归方法就是我们进行化归的措施、手段和技巧。
The idea of returning to normalization is a common problem solving thought in middle school mathematics. It can be seen from the definition of the thought of reverting to the thought that in the course of reverting to the thought, there are three basic elements: the goal of reversion, the goal of reversion and the method of reversion. To return to the object is what we need to transform in the original problem; to return to the goal is that we hope to achieve the goal of the process of return; and the return to the method is that we go through the measures, means and skills.
