In this paper, we regard the superconductor as an anisotropic Fermi system, taking into account topological transitions of the electronicenergy. We have worked out the relationship between the transition temperature T and chemical potential, and other thermodymanic quantities on the basis of the model of three overlapping energy bands. The results are in agreenment with experimental data.
