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 Mrk4 21 and Mrk501 with the data of Tibet I air shower array from 1990 June to 1 993 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 thes e candidates. The integral distribution of significances is checked by the Kolmogorov-Smirnov test which examines the divergence from a standard norma l distribution. No significant deviation is found. Flux upper limit is obta ined for each source at 95% C.L.
