摘　　要：在源的质心固定的视超光速模型的基础上,本文进一步推导出质心运动情况下的视超光速运动的视速度方程。然后,在喷流方向与源的退行方向相反的情况下,推导出核与子源速率相等条件下及核固定条件下求子源真实速度的方程。对子源的真实速度,本文最后给以简单地讨论。Based on the relativistic superluminal model of the apparent superluminal motion, under the condition that the center of mass of a superluminal radio source remains motion relative to the observer,the equation of apparent velocity between nucleus subsources is derived. Under the comdition direction of jet and movenent of superluminal radio source are opposite,under the condition that velocity of nucleus and components of SLS are equal and under the condition that nucleus fixed, the equations of real velocity of theirs are derived Finally,the paper briefly discusses the real volocity of the components in a superluminal radio sources.
