摘要

Assuming that the Broad Absorption Line Region - BALR (originated in a disk wind) is composed of a number of successive independent absorbing density layers, which have apparent rotational and radial velocities and where ions have random velocities, we applied a model in order to obtain the kinematical parameters of BALR, by fitting the broad absorption lines. The model can be easily used in fitting the observed absorption lines, providing us with basic kinematical parameters of BALR (random, rotational and radial velocities). Fitting broad absorption lines of several BALQSOs observed with the HST we discuss the fraction of the rotation and random motion in the BALR. Moreover, using the obtained parameters from the best fit we discuss the general characteristics of the BALR which are in support of the disk wind origin of the region.
