Abstract:

It is shown that the minimal value of the synchrotron emission brightness temperature at the frequency 408 MHz in the directions of second type supernovae remnants and pulsars increases sharply in the first thousand years after the supernovae explosions, and then it decreases up to the background value during a time of order of one million years. The cosmic rays acceleration is discussed as a possible reason of such a strong enhancement of the synchrotron emission intensity at the initial stage of supernovae's Stromgren zone evolution.
