Abstract：
This paper discusses the method of searching for TeV gamma ray point sources and estimates the significance of statistical differences between on-source and off-source observations by using student variable t.Based on Bayes theorem,the number of observed signals, and the detection efficiency via Monte Carlo simulation,the differential energy spectrum of TeV gamma ray from Crab Nebula are calculated.
