摘要：

Comparing the Hartree-Fock equations with the self-consistent equations for nonideal bose gas systems, we have shown that the energy gap in the elementary excitation spectrum appears due to a contradictory behavior of the Hartree-Fock approximation arising from different topological structure diagrams which correspond to the self energy.
