摘要：

We consider possible of effects of out-flowing plasma on the high-energy continuum spectra of accretion powered compact objects. We have developed an analytical formulation for the emergent spectrum of such systems, and performed model fitting on several Galactic X-ray binaries. Notably, Cyg X-3, is which is widely believed to be characterized by hot, dense circumstellar winds, provides a useful test case. Data from INTEGRAL and RXTE are included in our analysis. We further consider the possibility that the distortion of the power-law continuum above 10 keV may in some cases be explained by these spectral softening effects.
