Summary

THE BEHAVIOUR OF SUPERCONDUCTING ORDERING PARAMETER D (T) AND THERMAL CAPACITY OF A TWO-BAND SUPERCONDUCTOR WITH A NARROW BAND NEAR THE FERMI LEVEL IS CONSIDERED FOR A WIDE RANGE OF TEMPERATURES AND ELECTRON CONCENTRATIONS. THE CHARACTERISTIC FEATURES OF THE CALCULATED DEPENDENCE D (T) ARE IN QUALITATIVE AGREEMENT WITH EXPERIMENTAL DATA ON HIGH-TEMPERATURE SUPERCONDUCTORS. A NON-MONOTONIC TEMPERATURE DEPENDENCE OF THERMAL CAPACITY OF THE TWO-BAND SUPERCONDUCTOR AT T LOWER THAN CRITICAL TEMPERATURE IS PREDICTED.
