摘要：
A general thermodynamic approach is presented towards a triple point shift in arbitrary spatially limited systems with a curvilinear interface, including interfacial phases, small particles, and matter in pores. The suggested approach is based on using the coupling equations for vapor pressure over the bulk and spatially limited media together with the Clausius-Clapeyron relationships, and allows one to explain the effect of different physical-chemical parameters on the value and sign of the shift in the phase transition temperature. Besides, an explanation was offered within the developed theory for the difference in the melting points of different crystal faces, the presence of a nanometer melt layer for the substance in fine pores, and the formation of premolten or presolidified shell about nanoparticles.
