Abstract

A two-step (fast + slow in comparison to the exponential law) behavior of radio-emission fluxes was discovered by the differential method in the phases of growth and decay during an analysis of radio-burst observation data received at IZMIRAN by means of meter-band spectrographs and fixed-frequency radiometers. It was shown that the observed fast mode of flux growth may be connected with the fast mode 3013 MHz of the acceleration of the electrons responsible for synchrotron radiation of the flare in the microwave band.
