Аннотация:CpFit program for joint approximation of heat capacities and enthalpies (heat contents) by means of Einstein-Planck functions sum has been developed. It uses algorithms for automatic search of number of functions in the sum and automatic search of initial approximation for model parameters. The program also allows to use arbitrary extra terms for approximation of heat capacity anomalies such as lambda-transitions, Schottky anomalies etc. Experimental data for thorium and uranium dioxides, natrolite, potassium and thallium substituted natrolites were successfully approximated in wide ranges of temperature.
