This article considers a mathematical model of forced bifurcation oscillations of a three-mass chain system, when the measure of its dynamic susceptibility is incommensurable with the measures of forced bifurcation forces. The equivalent medium inside the allocated volume of the filler of the solar installation or filler, or its movement is reversible when turbulence occurs.
Distributions of perturbations caused by the internal instability of the pre-central layer after abolishing conditions under a focused shear load in the zones of solidification, crystallization and cooling are obtained. The results of the comparison of the pre-central and central layers are presented.
