Only about one thousandth of all close binaries remain bound following the collapse of one of the components. The bound binaries may show themselves as X-ray sources. About 100 strong X-ray sources and about 1000 weak ones are likely to exist in the Galaxy. The cause of the disruption of binaries is the asymmetry of a supernova explosion. During a supernova explosion, 30-70% of the stellar mass is ejected, and a newly born relativistic star receives from 5 to 15% of the shell's total impulse. We define how the parameters of a system change during an asymmetric explosion of one of the components. The expressions obtained are used to describe the change in the parameters of Her X-1 and Cen X-3 type systems.
