  Recent advances in the X-ray and soft gamma-ray observations of accreting
black holes and microquasars, in particular, are reviewed. The radiative
processes responsible for the emission are discussed briefly. The hybrid
thermal/nonthermal Comptonization model is shown to describe well the observed
broad-band spectra. We also comments on alternative phenomenological and
physical models that are used to describe the X/gamma-ray spectra of accreting
black holes. Among those are the "standard" model (i.e. disk-blackbody plus a
power-law), pexrav, bulk motion Comptonization, and synchrotron emission from
the jet.
