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.

1推导了辐射压加速宽线云团径向外流，以及引力下落和转动等BLR运动学模型的谱线轮廓表达式，并考虑到光致电离计算表明的云团本身对Hβ和HeIλ5876谱线的辐射差异，用数值方法计算了它们的谱线轮廓，发现普遍流行的辐射加速气体外流模型不能解释HeIλ5876线宽大于Hβ线宽的观测事实，而引力下落模型则可以较好地解释观测，因此我们倾向于认为、径向内流运动很可能是BLR内的发射线云团真实运动的一个重要成分。
