摘要：

A model is presented for the separation of the observed X-ray luminosity of radio quasars into relativistically beamed and isotropic contributions. It is shown that the relativistically beamed component is intrinsically only a small fraction of the isotropic component. Implications of the beaming are considered, including its effect on the X-ray power-law spectral index in the Einstein IPC band and on the equivalent width of the iron line emission at approximately 5 keV observed in some quasars.
