| 摘 要： | We study the possibility of high-energy gamma-ray emission from the known 1130 radio pulsars based on the outer gap model of high-energy emission from pusars.We estimate the fractional size of outer gap,the integrated flux,the gamma-ray luminosity for each known radio pulsar,and find that only 14% of the known radio pusars are gamma-ray emitters according to the outer gap model.In the sample of possible 156 gamma-ray pulsars,our statistical analysis indicates that the distributions of the spin-down powers and the ages of these pulsars concentrate mainly on 10^33.5-10^39 erg/s and 10^3-10^7y,respectively.The predictions of gamma-ray pulsars detected by the AGILE and GLAST missions are given.
