Some Peculiarities of the Law of Degradation of Energy

Is shown, that there are conditions, when the small deviations from conditions of applicability of the law of degradation of energy can have results , which are beyond of its frameworks. There is an apparent breaking of the law of degradation of energy. The example of such apparent breaking is given. As an example the transformation of noncoherent high-frequency wave into high-frequency coherent high-frequency wave and noncoherent low-frequency is considered. Is shown, that the presence of stochastic layers in phase space results in heterogeneity of phase space and, generally, to absence of equivalence of cells of phase space on isoenergetic hypersurface, and also to breaking of the adiabatic invariants. This feature also breaks conditions, at which the law of degradation of energy is carried out. The possible other reasons of breaking of the law of degradation of energy are discussed.
