【Abstract】 The results of statistical analysis concerning about the fluxes and luminosities obtained by IPC of Einstein Observatory are reviewed in the paper. The evolutionary properties and relations of the X-ray luminosity with the optical luminosity, the radio luminosity and radio morphology are discussed for a mixed samples of quasars, i.e.,optical and radio selected quasar samples as well as X-ray selected samples.更多还原
