The modified expression of the broad emission-line profiles ire derived for the outflow kinematics model of the BLR driven by the radiation pressure. Taking into account the difference between the two lines HeI λ5876 and Hβ, it is shown the fact that the observed line width of HeIλ 5876 is broader than that of Hβ cannot be explained by the popular outflow BLR model evoked by W. G. Mathews. For comparison, line profiles of the gravitational infall model and orbital disk model are also calculated; the later is in good agreement with the observations Thereupon, conclusion is reached that the gravitational infall is an important process in the real BLR gas motion.

As a result, parts of the dust cloud have become stratified, pointing toward Merope. The closest particles are the most massive and the least affected by the radiation pressure. A longer-term result will be the general destruction of the dust by the energetic starlight.
