中文摘要：

本文通过对伽玛暴瞬时辐射的持续时间T90、各向同性光度Liso和各向同性能量Eiso等观测物理量进行分析，发现持续时间T90分别和各向同性光度Liso、各向同性能量Eiso之间存在强相关性，并且在环状、厚盘的吸积盘模型的框架下可以很好解释观测数据；同时认为伽玛暴的瞬时辐射的持续时间‰与黑洞吸积盘的吸积时标tdisk相关，各向同性光度Liso与吸积率M成正比，各向同性能Eiso与吸积盘的总质量Mdisk成正比，进而帮助对伽玛暴中心引擎的理解．

英文摘要：

We analyzed the observed data about the duration T90, isotropic energy Eiso and isotropic luminosity Liso of the Gamma - ray Bursts. The strong correlation was found between the duration Tgo and isotropic luminosity Liso, isotropic energy Eiso. The observed data can be well interpreted in the framework of the accretion disk model of annular and thick disks. It was held that the duration Tgo was correlated with the accretion time scale of the black hole accretion disk tdisk, that the isotropic luminosity Liso was in positive proportion to the accretion rate M^·, and that the isotropic energy Eiso was in positive proportion to the total mass of the accretion disk Mdisk. The current analysis is beneficial to the understanding of the center engine of GRBs.
