摘要：

We undertake a quantitative investigation, using Monte Carlo simulations, of the amount by which quasars are expected to exceed radio galaxies in optical luminosity in the context of the 'receding torus' model. We compare these simulations with the known behaviour of the [O III] lambda 5007 and [O II] lambda 3727 emission lines and conclude that [O III] is the better indicator of the strength of the underlying non-stellar continuum.
