我们报告了伽玛射线暴（GRBs）的时间变异性和峰值亮度之间相关性的测试结果，使用了比Reichart等人可用的更大的红移GRBs样本（32），并使用了这些作者引入的变异性测量。结果令人困惑。假设各向同性等效的峰值光度，如Reichart等人所述，仍然发现了相关性，但与先前报道的幂律相关性较低且不一致。假设在已知射电角的16个GRB的子集中，校正了GRB射电后的峰值光度，相关性就变得不那么显著了。关键词：方法：数据分析-伽马射线：爆发。
We report test results of the correlation between the time variability and the peak luminosity of gamma-ray bursts (GRBs), using a larger sample (32) of GRBs with known redshift than that available to Reichart et al., and using as a variability measure that introduced by these authors. The results are puzzling. Assuming an isotropic-equivalent peak luminosity, as had Reichart et al., a correlation is still found, but it is less relevant and inconsistent with a power law as previously reported. Assuming as the peak luminosity that corrected for GRB beaming for a subset of 16 GRBs with known beaming angle, the correlation becomes slightly less significant.
