按照γ射线暴火球模型的动力学演化规律，利用相对论电子在磁场中作同步加速辐射时谱分布的特点，用求峰值频率辐射的方法，计算了γ射线暴红光波段余辉辐射流量随时间的变化.与γ射线暴GRB970228的观测结果比较，符合甚好，说明同步加速辐射是γ射线暴余辉主要的辐射机制，也进一步证明了火球模型的正确．

According to the dynamics evolution rule of GRB in the model offireballs, and using the charactenistic of the spectra distribution of ultrarelative electron in magnetic field as well as the methord of the radiation in peak frequency, we calculate the variation of the R-band flux density of GRB after-glows with time, which is very consistent with observed spectra of GRB970028. Our result implys that synchrotron radiation is main mechanism of Gramma-ray bursts after-glows, and proves the validity of the model of fireballs.
