摘要：

We have obtained high S/N spectra for two Fe II-strong quasars, IRAS 07598+6508 and PHL 1092. In addition to Fe II features, we have identified emission lines of Fe I and Ti II. We believe the energy source for the line emission is heat and propose an idea in which an accretion disk may produce the observed emission.
