在火球模型中,伽马射线暴(GRB)喷射物具有一系列体洛伦兹因子(假设 M α -S),这在物理上更加真实。当后者 d 时,喷射物的低洛伦兹因子部分将赶上高洛伦兹因子部分。
In the fireball model, it is more physically realistic that gamma-ray burst (GRB) ejecta have a range of bulk Lorentz factors (assuming M α −S). The low Lorentz factor part of the ejecta will catch up with the high Lorentz factor part when the latter is d
