摘要We derive a simple analytical formula to describe the evolution of spectral index beta in the steep decay phase shaped by the curvature effect with the. assumption that the spectral parameters and Lorentz factor of the. jet shell are. the same for different latitudes. Here, the value of beta is estimated in the 0.3-10 keV energy band. For a spherical thin shell with a cutoff power-law (CPL) intrinsic radiation spectrum, the spectral evolution can be read as a linear function of observer time. For the situation with the. Band function intrinsic radiation spectrum, the spectral evolution may be complex. If the observed break energy of the. radiation spectrum is larger than 10 keV, the spectral evolution is the same as that shaped by jet shells with a CPL spectrum. If the observed break energy is less than 0.3 keV, the value of beta would be a constant. For others, the spectral evolution can be approximated as a logarithmal function of the observer time in general.
