The process of high-speed energy transfer in media with 
allowance for the effects of the internal structure is considered 
in the context of nonequilibrium statistical mechanics and the theory 
of nonlinear operator systems. The self-consistent nonlocal-hydrodynamic 
approach proposed enables one to introduce multiple scales and multiple 
stages of the processes of exchange of momentum and energy into the 
continuous description of a medium. Large-scale fluctuations transferring 
heat in a wave manner are generated in the medium at the initial stage 
of rapid heating. The measurable characteristic of these fluctuations, 
i.e., the dispersion of mass velocity, has been introduced into the 
nonequilibrium equations of state of the medium. The mechanism of 
regular heat conduction is established in the medium at the final 
stage of the process, and a synergetic formation of new structures 
occurs in the interval.
