摘　　要：本文研究了对流扩散方程的一种并行格式.利用一组saul’yev型非对称格式进行二次构造,分别得到了一类并行GE格式和GEL、GER格式;进一步推广,得到绝对稳定的交替分组显式AGE格式,并用数值例子检验AGE格式的数值计算效果.In this paper, we study parallel algorithm of convection diffusion equation. By structuring twice from a group of asymmetrical schemes of saul yev, we get a class of perallel formula of GE, and the schemes of GEL, GER respectively; furthermore, obtain the absolute stability alternating group explicit scheme of AGE, and test calculated effect of the scheme of AGE by an example.
