摘要：
We calculate the spectra expected from internal shocks in unsteady relativistic wind models of gamma-ray bursts, suitable for events of arbitrary duration and light curve. The spectral energy distribution of the burst is calculated over photon energies spanning from eV to TeV, for a range of event durations and variability timescales. The relative strength of the emission at different wavelengths can provide valuable information on the particle acceleration, radiation mechanisms, and the possible types of models.
