Search for 10TeV gamma-ray emission from Supernova Remnants and Active Galactic Nuclei

A search for 10Tev gamma-ray continuous emission from 58 Supernova Remnants which include Crab Nebula and 25 Active Galactic Nuclei which include Mrk421 and Mrk501 with the data of Tibet I air shower array from 1990 June to 1993 October is executed by the method of equi-zenith angle to estimate the background events. The significance of DC excess is calculated according to the Li and Ma prescription. No significant DC excess is observed from these candidates. The integral distribution of significances is checked by the Kolmogorov-Smirnov test which examines the divergence from a standard normal distribution. No significant deviation is found. Flux upper limit is obtained for each source at 95% C.L.
