%X 谱方法是处理微分方程的常用方法,本文以理论完善的谱方法为基础,详细介绍了切比雪夫多项式通过S-L问题的由来与切比雪夫多项式的部分性质,并利用这些性质将这些正交多项式作为基对函数进行展开,从而数值求解偏微分方程,我们利用案例来展现其具体的运算过程并验证其方法的有效性。
Based on Spectral Method, we introduce the origin of Chebyshev polynomials via S-L problems and some properties of Chebyshev polynomials. With these properties, we use these orthogonal poly-nomials as basic functions to solve partial differential equations. Also, we use examples to show the detailed operations and verify its effectiveness.
