摘要
对于含有源汇项的定常对流扩散方程，本文导出了一种点点精确有限解所差分格式的一般公式，并讨论了源汇项的几种离散形式及对应差分格式的精度,最后利用数值算例验证了本文差分格式的性能．
In this paper, a general accurate formulation of finite analytic difference scheme was devel-oped for solving steady convection - diffusion equation with are term, and various discretization formsof source term is discussed. The accuracy of the numerical methods was verified with numerical testing.
