摘要
针对对流扩散方程,与传统的典型差分方法对比,给出一种新型差分格式的待定系数法,并进行稳定性和截断误差分析,所得的格式精度高且绝对稳定.
Taking one-demenional convection diffusion equation as the object of study,a difference scheme of under-mined coefficients was given. Then analyzed its stability and truncation error. The new scheme with highprecision was absolutly stable.
