报告摘要：

Gamma-ray burst (GRB) is one of the most violent events in the deep universe. Ithas two emission stages. The earlier one is the prompt emission inγ-ray band. After theprompt emission, we can see its multi-wavelength afterglows.After decades of investigation, the origin of the prompt emission remainsunclear, especially the radiation mechanism. The synchrotron emission or the photosphericemission origin has been long-debated.

Iwill give a detailed review on the researches of GRB prompt emission, both theobservations and models. Then, I will talk about my theoretical studies withinthe framework of the probability photosphere model, considering the morenatural and reasonable physical conditions of jet structure, jet compositionand viewing angle. Also, which observational and statistic features can be reproducedby the modified model will be shown.
