| 摘 要： | The multiband nonthermal emissions in radio, X-ray, and very high-energy(VHE) γ-ray bands from two distant blazars, H 2356–309 and 1ES 1218+304, havebeen detected, and, especially from recent observations with the Suzaku, MAGICand VERITAS telescopes, clearly reveal nonthermal power-law spectra. We study thebroadband nonthermal spectra of the two sources by using a combination of a one-zone homogeneous synchrotron self-Compton (SSC) model and an inhomogeneousconical jet model, where the new external backgrou...
