  Based on photoionization calculations we present a study of the NLR emission
line ratios of Narrow-line Seyfert 1 (NLS1) galaxies. In particular, we
investigate the influence of different EUV - soft-X-ray spectral shapes (a
giant soft excess, a steep X-ray powerlaw, the presence of a warm absorber) and
NLR cloud properties (density, abundances, distance from the continuum source)
on the predicted optical emission-line ratios like [OIII] and [FeXIV].
