主要工作是：具体研究火球所抛出壳层的相对论流体动力学演化，应用同步加速辐射机制，通过由共动坐标系到实验室坐标系的相对论变换，得到Gamma暴余辉的光变曲线。
The hydrodynamic evolution of the fireball shell is comprehensively studied . Using the synchrotron mechanism and relativistic transformation from co-moving frame to lab frame , the light curves of the gamma-ray burst afterglow are obtained .
