最近的研究表明:短γ射线暴(γ暴)的辐射特性和长γ暴的前两秒的辐射特征相似,这引发了对以前争论的问题,即:这两类暴是否是本质上相同的暴?本文主要对和γ暴谱形和光变曲线有关的两个量的分布进行了K-S检验.分析表明:这两类暴的分布是不同的,这和广为接受的两类γ暴事件产生于不同机制的观点是一致的.

Recent research suggests that the emission properties of short gamma-ray bursts (GRBs) are similar to that of long GRBs in the first 2 s, if the two classes of bursts are intrinsically the same. We mainly present in this paper a K-S test on the distributions of two quantities associated with the spectra and light curves of GRBs. Our analysis shows that the distributions differ for the two classes of GRBs, in agreement with the generally accepted view that they are events arising from different mechanisms.
