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