【 摘 要 】

The dependence of pulse temporal properties (pulse width, pulse rise width and pulse decay width) on energy is power-law function. Some correlated relationships between the power-law indices of the pulse time properties on energy and the spectral lags, relative spectral lags, spectral parameters of band function, and photon flux using a well-separated long-duration 𝛾-ray burst (GRB) pulse sample is demonstrated here. We argue that the curvature effect can explain the correlated properties.
