We use the accretion disk/corona+jet model to fit the multi-band spectralenergy distributions (SEDs) of two unusual radio-intermediate/quiet quasars. Itis found that the optical/UV emission of III Zw 2 is probably dominated by theemission from the accretion disk. The X-ray emission should be dominated by theradiation from the jet, while the contribution of the disk corona isnegligible. The optical/UV component in the SED of PG 1407+265 can be wellmodeled as the emission from the accretion disk, while the IR component isattributed to the thermal radiation from the dust torus with an opening angle ~50\circ. If the X-ray continuum emission is dominated by the synchrotronemission of the jet, the source should be a "high peak frequency blazar", whichobviously deviates the normal blazar sequence. The observed SED can also befitted quite well by the accretion disk/corona model with the viscosityparameter ? = 0:5. The spectrum of the accretion disk/corona in PG 1407+265satisfies the weak line quasar criterion suggested in Laor & Davis.
