摘　　要：介绍了ComptonORO卫星对γ暴的最新观测结果。观测表明，γ暴源的空间分布是各向同性但不均匀的。这种分布基本上排除了γ暴起源于银盘内中子星的模型，表明γ暴要么位于展延的银晕里，要么位于宇宙学距离上。我们讨论了目前关于γ暴起源的各种理论模型，包括两个中子星相撞、黑洞吸积等。最后还分析了存在两种不同类型γ暴的可能性。We have introduced the recent observational results obtained by the burst and transientsource experiment(BATSE) on the Compton Gammaray Observatory. They showthat the distribution of the gamma-ray burst sources is isotropic but nonuniform, andindicate that the bursts located at either the extended galactic halo or the cosmologicaldistance. Then, we have discussed the models about the origin of gamma-ray bursts,including the neutron star merging model and black hole accreting model etc.. Finally,we have also discussed the possibility that there may be two different kinds of gammaraybursts.
