Burst duration measurements for a GRB sample

Several gamma-ray bursts (GRBs) last much longer (~hours) in {gamma}-rays than typical long GRBs (~minutes), and it has recently been proposed that these "ultra-long GRBs" may...部分伽马射线暴（gamma-ray bursts, GRBs）在γ射线波段的持续时长可达约数小时，远长于典型长伽马射线暴（long GRBs）的约数分钟。近期有研究提出，这类被称为‘超长伽马射线暴（ultra-long GRBs）’的现象或许……
