摘要

我们考虑了大质量恒星周围电离氢区域的粒子动力学，以估计粒子最终速度的设定时间。我们确定了考虑尘埃和气体相对运动的电离氢区演化模型的终端速度近似的适用范围。为此，我们对大质量恒星形成区的几种典型尘埃颗粒的运动方程进行了数值求解。

THE GRAIN DYNAMICS IN A REGION OF IONIZED HYDROGEN

We consider a grain dynamics in a region of ionized hydrogen around a massive star for estimating a time of setting a grain terminal velocity. We determine the applicability limits for the terminal velocity approx-imation for evolutionary models of ionized hydrogen regions that take into account a relative motion of dust and gas. For that purpose, we solve numerically the equation of motion for dust grains of several kinds typical for massive star forming regions.
