摘要
排列问题是中学数学教学中学生普遍感到困难的内容。作者用集合论中映射计数的思想方法,对其进行较深层次的阐释,以有助于中学数学教学。
In the mathematical contents of the middle school, Permutation and Combination are the part which is felt generally difficult by students, and this article gives out illustrations to permutation within them in the language of modem mathematics.
