英文摘要	The physics behind the spectral energy distribution (sed) of blazars remains open. we assembled 36 blazars to tackle the factors that control their sed. now, many blazar spectra have the "double hump" feature in the radio and far-ir frequencies. for these a parameter, delta, is created to characterize the behavior of the sed. we found a significant correlation between the broad-line luminosity (l-blr) and delta. because l-blr is an indicator of the accreting power of the source in blazars, we derived a linear correlation, delta proportional to m-1/3.18, which suggests that the sed of blazars may depend on,the accretion rate, like that of bl lac objects. we also found a significant correlation between rh and delta for a sample of 11 blazars (out of one of 36) with available black hole masses. this implies the eddington accretion ratio may influence the shape of the sed of blazars.
