英文摘要Four well-sampled Spectral Energy Distributions (SEDs) of PMN J0948 + 0022 are fitted with the syn + SSC + EC model to derive the physical parameters of its jets and to investigate the spectral variations of its SEDs. A tentative correlation between the peak luminosity (L-c) and peak frequency (nu(c)) of its inverse Compton (IC) bump is found in both the observer and co-moving frames, indicating that the variations of luminosity are accompanied by the spectral shift. A correlation between L-c and delta is found, and thus the magnification of external photon field by the bulk motion of the radiation regions is an essential reason for the spectral variation since, IC bump of PMN J0948 + 0022 is dominated by the EC process.
