Abstract
It has been shown that peculiar phase transitions of appearing occasional zeros of the gap of the electron spectrum can occur in superconductors at finite temperatures. The form of the thermodynamic features upon such disappearance of the gap on lines or at points of the Fermi surface has been determined.
