摘要：

The Tibet air shower array at an altitude of 4300 m (above sea level) has been in operation since January 1990, We have searched for continua] 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 x 10(-12) cm-2s-1 for the Crab Nebula, 1.1 x 10(-12) cm-2s-1 for Cygnus X-3, and 0.58 x 10(-12) cm-2s-1 for Hercules X-1 at the 95% C.L. This is the first observation, with an air shower array, for these sources in the 10-TeV energy region.
