摘要：

Broad emission line regions in AGN are connected with the outer layers of accretion disks. This has been shown by means of line variability studies of individual AGN as well as line profile studies of AGN samples. We could model the broad-line profiles in AGN in a simple way only through rotational broadening of Lorentzian profiles. To individual emission lines belongs one typical Lorentz profile only with a fixed turbulence velocity: e.g., 500 km/s for H beta, 3000 km/s for C IV lambda 1550. The rotation velocities in the broad line regions of the AGN range from 1000 to 7000 km/s.
