摘要: 火球模型被认为是γ射线暴的标准模型, 而火球产生的机制是多方面的, 其中之一就是奇异星相变, 它既解释了γ射线暴的短时标、高能量特征, 又避免了火球的重子污染这一最大难题.通过对γ射线暴的能源机制研究, 探讨了宇宙学距离(~ Gpc)处γ射线暴的能量来自奇异星相变的可能性, 进而认识了奇异星模型的独特优势.

Abstract: The fireball model is universally accepted as the standard model in explaining γ-ray bursts.Phase transition of strange stars is one of the factors leading to fireball appearance, which not only can explain the short scales and high energy of γ-ray bursts, but also address the issue of baryon pollution of the fireball. On the basis of researching the energy mecha- nism of gamma-ray bursts, the possibility that the energy of gamma-ray bursts at cosmology distance(~ Gpc)comes from phase transition of strange stars is discussed.
