摘要

A physical concept of thermodynamic physical system states has been proposed with application to aqueous solutions at ultrahigh dilution that are low stable to external impacts. Based on the thermodynamic analogy of the solution states and the condensed physical system state, the feasibility of realization of low-stability states is demonstrated. An analysis of representations about thermodynamic and structural-phase states of water and estimations of the structure of aqueous solutions at ultrahigh dilution allow us to assume reasonably the feasibility of realization of low-stability structurally-phase states of aqueous solutions at ultrahigh dilution when the system goes into a new structural state under an external impact (mechanical shaking). Moreover, the external impact can be sufficiently small, but the structural system state can change quite significantly. It is discussed how the state of a suitable symmetric liquid solution of a substance, for which the effect of small impact of the external force in different forms (for example, shaking) is important, can be obtained experimentally. This approach allows the role of Epstein’s effect in shaking of chemical solutions to be estimated by mechanochemical methods.
