摘要：
We studied the disk emission component hidden in the single-peaked broad emission lines (BELs) of active galactic nuclei (AGN) using a two-component model. We assumed that the broad lines are formed in an accretion disk plus a surrounding non-disk region, with isotropic cloud velocities. To compare simulated line profiles with observed ones we measured the full widths (at 10 per cent, 20 per cent and 30 per cent of the maximum intensity). We found that the hidden disk emission may be present in BELs even if the characteristic of two-peaked-line profiles is absent. We found that in the case of the hidden disk emission in single-peaked broad-line profiles, the disk inclination tends to be small and that the contribution of the disk emission to the total flux should be smaller than the contribution of the surrounding region.
