Abstract
This work presents the spectral and temporal features of radio bursts with fine structures (FSs) at broad band from 1.1 to 7.6Â GHz. Fifteen burst events are studied with high frequency and temporal cadence observation from the Solar Broadband Radio Spectrometer at three frequency bands. It is found that the amount and species of radio FS decrease with increasing frequency band; the pulsation, type III burst and continuum are most frequently recorded; almost in all the burst events, more radio FSs occur before the soft X-ray (SXR) maximum than after; at 1.1-2.06Â GHz, all types of radio FSs have more before the SXR peak except fiber; at 2.6-3.8Â GHz, pulsation, fiber and spike prefer to appear after the peak; the separation between neighboring emission lines of zebra pattern increases with increasing frequency and the magnetic field deduced from the whistler model is 29-86Â G at 1.1-2.06Â GHz and 89-268Â G at 2.6-3.8Â GHz.
