We analyze the main parameters, that are significant from the standpoint of evolution, of the ten most reliably observed black-hole candidates among the components of close X-ray binary systems. The principal driving forces of the evolution of these systems can be established by analyzing their evolution. These are induced (in binaries with F-M donors) and self-induced (in binaries with O-B donors) stellar winds from donors that almost fill their Roche lobes. The driving force of the evolution of V404 Cyg, XN Oph, and XN Sco is probably evolutionary expansion of the donors, a solar-mass star with a degenerate helium core. The space velocities of X-ray binaries with black holes can be explained in terms of the recoil effect produced by supernova explosions in close binary systems.
