摘　　要：Using the high time-resolution and 64ms resolution data of the burst and transient source experiment,we performed an autocorrelation analysis of the energy dependence of burst pulse width in short gamma-ray bursts.A method free from potential cosmological effects has been proposed.This allows us to use a sample with a size comparable to that used for long and bright bursts.Our result shows that the profiles of short bursts exhibit a very good power-law between profile width and photon energy,with an index~-0.3.This result is consistent with a united origin of the bimodal distribution.
