ENERGETIC EXCESS FUNCTIONS OF HELIUM ISOTOPES MIXTURES IN THE TRANSCRITICAL TEMPERATURE RANGE.

[In Russian. / En russe.]

Author(s) : KARNACEVIC L. V.

Type of article: Article

Summary

CALCULATIONS OF EXCESS GIBBS POTENTIAL, EXCESS ENTROPY AND EXCESS ENTHALPY OF HELIUM 3-HELIUM 4 MIXTURES IN THE TEMPERATURE RANGE 4.5-14 K AT PRESSURES TO 3 MPASCALS ARE MADE ON THE GROUND OF THE EXPERIMENTAL P-V-T DATA. THE DEPENDENCES OF THOSE FUNCTIONS ON TEMPERATURE, PRESSURE AND CONCENTRATION OF MIXTURE ARE ESTABLISHED. RESULTS ARE COMPARED WITH CALCULATIONS BY PRIGOGINE THEORY. CALCULATIONS ARE MADE OF EXCESS CHARACTERISTICS OF HELIUM 3-HELIUM 4 SYSTEM IN TERMS OF GAS APPROXIMATION TAKING INTO ACCOUNT BOTH THE DIFFRACTION AND QUANTUM-STATISTICAL EFFECTS.
