| 摘 要： | 数学教学中充分和必要条件是很重要的,在高师数学教学中应用充分和必要条件可以使一些复杂的定理,概念变得简单直观。虽然书本中没有直接给出充分和必要条件的关系式,但经过归纳总结可得一定规律。这种关系式在泛函分析,常微分方程等学科中,对正确理解和把握概念起作重要的作用。

| Abstract: | Necessary condition and sufficient condition is important in teaching mathematics.It can transform some complication theory and definition into easily understand in teaching high mathematics Although many relationships of necessary condition and sufficient condition did not display in book,we can get some rules through analysis.And it has bright future in some book,such as functional analysis,differential equations and so on. |
