Abstract Durations of gamma-ray bursts (GRB’s) are featured by >2s subset and <2s one, with initial corresponding energy ratio being 20:1. It is found that supernova remants(SNR’s) turnover frequencies peak at 100 and 500 MHz. After assuming that GRB’s originate from hypernova and making an analysis on the evolution of GRB’s, we find that the initial energy of two GRB subsets leads to a different radio-frequency turnover of their remnant spectra, which accords positively with the turnover-frequency ratio of SNR’s.
