| 摘 要： | 反证法是初等数学中重要的推理方法之一，它在数学中有广泛的应用。但比较抽象，容易造成思维定式，教学中应注意不失时机地渗透反证法的依据和原理，才能使学生灵活掌握，提高应用反证法去解决代数、几何中的一些问题的能力。

| Abstract: | Reduction to Absurdity is one of the most important methods of Ratiocination in Elementary Math. It is widely applied in Math. Reduction to Absurdity is so abstract that it easily causes definite forms of thought. Teachers should always pay attention to infiltrating foundations and theories of Reduction to Absurdity in teaching in order to improve students' abilities that deal with the problems solving of Algebra and Geometry by Reduction to Absurdity methods. |
