Query: A grid of Composite Models for the Simulation of Starburst Galaxy and
  HII Region Spectra   A grid of models for starburst spectra is presented and compared with
power-law models which represent AGNs. The models are composite, i.e., they
account for the radiation from the starburst and for the shocks created by
super-winds. Some interesting fit of models to observations are also discussed.
In particular, it is found that [OIII]/Hb ~can reach values as high as for the
AGN when the emitting clouds are close to the starburst region. Moreover CIV
lines can be high even if SiIV lines are relatively low. It is found that for
some line ratios, which have similar values for starburst and AGN models, the
width of the lines can distinguish between the two types.
