The described intrinsic model for absorption line systems in QSO spectra is based on the assumption that the absorbing material consists of interstellar gas which has been swept up by winds emanating from QSO. The model is supported by studies of the physics of radiatively accelerated winds; these studies show that a significant fraction of the radiative energy output of a QSO must be converted into kinetic energy of an outflowing wind. The model is used to estimate parameters which suggest that absorption takes place in thin dense shells at distances of the order of kpc. The model indicates that, in contrast with the formation of the shell, the flow behavior depends strongly on the parameters.
