摘要
本文用简单的宇宙学模型 ,在标准烛光和均匀分布的假设下计算了γ射线暴的logN(>P)～logP分布 (大小谱 ) .在考虑了探测效率修正和死时间修正后 。
Assuming that the bursts have identical peak fluxes, i.e. the“standard candle” hypothesis is valid,and have also identical density, the log N(>P) ～log P distribution of γ ray bursts isanalyzed using the simple cosmological model. There is no significantdeviation between the theoretical result obtained from the cosmological modeland BATSE data corrected for trigger efficiencyand dead time.
