摘要：

We study quantitatively the formation and radiation acceleration of electron-positron pair plasmoids produced by photon-photon collisions near Galactic black holes (GBHs). The terminal ejecta velocity is found to be completely determined by the total disk luminosity, proton loading factor, and disk size, with no dependence on the initial velocity. We discuss potential applications to the recently discovered Galactic super-luminal sources GRS 1915 and GRO J1655 and possibly other GBHs.
