  The comparative behaviour of normal and anomalous averages as functions of
momentum or energy, at different temperatures, is analysed for systems with
Bose-Einstein condensate. Three qualitatively distinct temperature regions are
revealed: The critical region, where the absolute value of the anomalous
average, for the main energy range, is much smaller than the normal average.
The region of intermediate temperatures, where the absolute values of the
anomalous and normal averages are of the same order. And the region of low
temperatures, where the absolute value of the anomalous average, for
practically all energies, becomes much larger than the normal average. This
shows the importance of the anomalous averages for the intermediate and,
especially, for low temperatures, where these anomalous averages cannot be
neglected.
