Динамика и статистика дислокационных скоплений в деформируемых кристаллах льда

It is shown on the basis of analysis of the electromagnetic emission signals during compression of polycrystalline ice that an ensemble of mobile pile-ups of charged dislocations tends to the self-organized criticality state that is consistent to some nonequilibrium level of deformed polycrystal and long space correlations in dynamics of dislocation pile-ups.
