摘要
利用脉冲拟合方法，我们研究了由HETE-2卫星上的WXM和FREGATE仪器探测到的8个已知红移的GRB（GRB 010921、GRB 020124、GRB 020127、GRB 021211、GRB 030528、GRB 040924、GRB 041006、GRB 050408）在传统伽马射线波段（50-400 keV）和X射线波段（6-25 keV）之间的谱延迟。我们发现了单个GRB脉冲的谱延迟与其他可观测量（如光度、脉冲持续时间和峰值能量Epeak）之间的若干关系。所得结果与BATSE的结果一致，表明BATSE的相关性在较低能量（6-25 keV）下仍然有效。此外，我们发现谱延迟的光子能量依赖性可以与简单的曲率效应模型相协调。我们从不同角度讨论了这些结果的意义。
