摘　　要：本文介绍了γ射线暴整个能谱,从低能量30keV到高能量10MeV以及能谱中特征线,包括发射和吸收特征线的观测和研究现状。在此基础上,对γ射线暴的辐射机制进行了探讨,提出了一些可能的模型,并且以此对一些具体能谱进行了拟合,得到了满意的结果。The observational and theoretical researches on the energy spectra of Gamma-ray bursts, from low energy 30 keV to high energy 10 MeV and feature lines in their enlergy spectra including absorption and emission features, have been introduced in the paper. Based on these, the radiation mechanisms for Gamma-ray bursts are studied. Some possible models are proposed and using these models, we fit some representative spectra of Gamma-ray bursts. The results are satisfactory.
