摘要

The system of accretion disk and black hole is usually considered as the central engine of Gamma-ray Bursts (GRBs). It is usually thought that the disk in the central engine of GRBs is the advection-dominated accretion disk, which is developed from a massive (mass M_(disk)) torus at radius r_(disk). We find a positive correlation between the isotropic gamma-ray energy E_(iso) and duration (so-called T_(90)) for GRBs. We interpret this correlation within the advection-dominated accretion disk model, associating E_(iso) and T_(90) with M(disk) and viscous timescale respectively.
