摘要：
A geometric model of phase equilibria between NaKC4H4O6 center dot 4H(2)O crystal hydrate polymorphs was suggested. An analytic equation for its thermodynamic potential was obtained, and the temperature dependences of heat capacity and polarization were found. An analytic form of the interrelation between the anisotropic characteristics of NaKC4H4O6 center dot 4H(2)O was obtained, and their temperature dependences were calculated over a wide temperature range including polymorphic transition points.
