GRB主暴后，火球继续膨胀，根据暴后火球的动力学演化方程，考虑电子的分布随时问的变化，通过数值求解，得到光学R波段和X射线余辉与时间t的关系.计算结果与观测结果相比较，符合得很好.最后，还讨论了火球+激波模型的不足.

After the main part of a GRB, its fireball continuously expands. With the hydrodynamic equations for the postburst fireball, the authors study the distribution of electrons, which changes with time. The equations are solved numerically and the relations of the flux density of Optical afterglow in R band as well as the X- ray afterglow with time have been obtained. The results fit the observations quite well. Finally the shortcomings of the fireball + blast model are discussed.
