An approach to the derivation of kinetic equations describing the motion of accelerated particles in solids is suggested based on the microscopic phase density method. It is shown that the unified approach suggested makes possible to obtain all the known kinetic equations used for describing the interaction of accelerated particles with condensed medium as well as more exact expressions for the coefficients of these equations. A new type of the kinetic equation is obtained describing, in particular, ion channeling in complex single crystals.Ha ocHoBe MeToga MmpocKonmecKofi aa30~oB IIJIOTHOCTH npennomeH n o m o~ K sepea TsepAoe Teno.
