The absorptive effect of jets on the multi-waveband energy spectrum of the quasar 3C 279 is studied by using a jet model. Based on the timeindependent synchrotron self-Compton (SSC) model, it is assumed that in the jet, the radiant blob is blocked by the preceding cooled blob, thus the emission from the radiation region could be absorbed. This leads to the change of the energy spectrum. Our calculations indicate that the jet material exerts a strong absorption on the X-ray emission from the quasar radiation region, and that the absorbed energy will be re-emitted in the form of emission lines in the ultraviolet and soft X-ray wavebands. By using this model, we have reproduced the multi-waveband energy spectrum of 3C 279. Finally, we give a brief discussion on the obtained results.
