摘要：

The free energy of a two-band model, where superconductivity is induced by a repulsive interband interaction has been obtained. The fulfillment of stability conditions of normal and superconducting phases in this model has been proved. The dependence of superconducting gaps on temperature and the carrier concentration have been found. In general, the coefficients of the temperature dependence of gaps deviate from the BCS ones. Some experimental data on 2122-and 123-type systems are discussed.
