摘　　要：探讨了GRB(Gamma-Ray Burst,伽玛射线暴)光变曲线的Flux(光子峰值流量)与T90(GRB光子计数在5%~95%之间的持续时标)的关系.分别采用两颗卫星的最新数据,对Flux与T90进行相关分析.结果为:Flux与T90的对数值之间不显相关性,相关系数分别为R^0.12和R^0.04,表明GRB的持续时间与光变曲线的光子峰值流量不相关.The relationship between the light curves Flux of GRB （Gamma-Ray Burst） and T90 （duration containing from 5% to 95% of the total fluence of a GRB） is explored. The last data of two satellites are selected to test whether there is a relation between Flux and T90 or not. The result shows that there does not exist a proportional correlation between the logarithm of Flux and the logarithm of T90 with correlation coefficients R-0.12 and R- 0.04, respectively. Our finding shows that the Flux of light curve is not correlated to the GRB duration.
