英文摘要：

In this paper, a class of exponential explicit method for solving variable coefficient convective dittuslon equation is presented, which is based on a class of explicit method proposed by author. There are semi-explicit scheme, sigle alternating group explicit scheme and double alternating group explicit scheme. Numerical experiment is presented to confirm the accuracy and efficiency of the proposed method.
