[en] The phase transition of helium t o the superfluid state in narrow 100-600 A pores is studied calorimetrically. Features of a phase transition of the first kind are observed for helium in narrow pores (100-300 A). The parameter M in the phenomenological theory of superfluidity and also the coefficients A0, B0 and C0 in the three-term expansion of the thermodynamic potential are estimated. The latent heat of the transition and its dependence on the pore size are determined

[en] The phase transition of Agl superionic conductor was investigated by calorometric. A single phase transition was found at (153±5)oC which corresponds to the α - β transition. Calorimetric measurement showed an anomalously high heat capacity with a large discontinues change in the Arrhenius plot, was found above the transition temperature of β - α phase. The maximum heat capacity was found to be ±19.7 cal/gmol. Key words : superionic conductor, thermal capacity

[en] A study was made on thermal effects accompanying polymorphous transitions in Gesub(1-x)Tesub(x) alloys of different composition. It is shown, that thermal effects of polymorphous transitions in Gesub(1-x)Tesub(x) alloys with different diviation from stoichiometry depend significantly on Te content in alloy matrix and differ for α → ß and ß → ß-phase transitions in samples of the same composition
