| 摘 要： | 结合Swift和Fermi两个卫星的各自优点,选择Fermi/GBM和Swift/BAT同时触发的伽玛暴观测数据,发现GBM暴持续时间的平均值比BAT暴要小,但是它们的持续时间分布、伽玛暴本身的流量分布以及光子峰值能量分布(log N-log P分布)之间不存在系统性差异.所以,不同仪器的观测差异可能是由于仪器本身的灵敏度引起的,与暴的性质无关.

| Abstract: | Making use of Swift and Fermi satellites advantages and selecting the gamma-ray bursts observation data both by the Swift/BAT and the Fermi/GBM,it is found that the mean of the duration for the GBM bursts is lower than that of BAT bursts,while the distribution of the duration,the fluence in 15~150 keV and the photon peak energy flux doesn＇t show any statistically difference.The different observational properties of the different satellites may be caused by the sensitivity of the instruments,this paper concludes when the natures of the bursts may be the same. |
