Matching of two modes of the registration of surface energy for a problem about phase transitions in a thermoelasticity

In the present paper matching two modes of the registration of a ourface energy in a problem about phase transitions in the theory of a thermoelasticity will be arried out. In the first mode the surface energy is considered of a proportional interfacial area of phases. In the second case the surface energy is taken into account by an indirect fashion, as an integral from highiv derivatives of a field of displacements. The likenesses and differences of association of equilibrium states from parameters for two different of a regularization are become clear.
