摘　　要：西藏羊八井ARGO实验是对广延大气簇射事例进行观测研究的“全覆盖式”地面宇宙线观测实验,其主要目的之一就是探测E＞10GeV的γ暴．通过Monte Carlo模拟,估算了ARGO实验探测10GeVγ暴所具有的灵敏度．ARGO is a ＂full coverage＂ air shower detector currently under construction in Tibet, China. One of the main goals of this experiment is to search for possible gamma-ray bursts （GRBs） with E 〉 10GeV. In this work, the sensitivity in observing a GRB （with a certain significance） by ARGO is found to be dependent on the flux of the GRB, the slope and the energy cutoff of its spectrum, as well as its time duration and the zenith angle at the observation.
