海拔4300 m（海拔）的西藏空气簇射阵列自1990年1月开始运行。我们在1990年6月至1992年1月期间搜索了蟹状星云、天鹅座X-3和武仙座X-1持续发射的10-TeV伽马射线。这三个源没有发现直流过剩。 95% C.L 下，蟹状星云高于 10 TeV 的通量上限为 1.2×10 -12 cm -2 s -1，天鹅座 X-3 为 1.1×10 -12 cm -2 s -1，武仙座 X-1 为 0.58×10 -12 cm -2 s -1
The Tibet air shower array at an altitude or 4300 m (above sea level) has been in operation since January 1990. We have searched for continual emission of 10-TeV gamma rays from the Crab Nebula, Cygnus X-3, and Hercules X-1 during the period from June 1990 through January 1992. No dc excess is found from these three sources. Flux upper limits above 10 TeV are obtained to be 1.2×10 −12 cm −2 s −1 for the Crab Nebula, 1.1×10 −12 cm −2 s −1 for Cygnus X-3, and 0.58×10 −12 cm −2 s −1 for Hercules X-1 at the 95% C.L
