论文摘要
已经详细研究了由重力透镜的横向运动引起的运动效应，而径向运动的效果被认为比横向运动的效应小得多，因此通常被忽略了。在这项工作中，我们发现当光发射器（或接收器）接近重力透镜时，径向速度效应与横向速度效应的数量级相同，其距离是冲击参数量表。显着的速度效应通常是由于引力透镜相对于光发射器或接收器的运动而进行的。
The kinematical effect induced by the transversal motion of a gravitational lens on the frequency shift of light has been investigated in detail, while the effect of the radial motion is thought to be much smaller than the transversal one and thus has usually been neglected. In this work, we find that the radial velocity effect on the frequency shift has the same order of magnitude as that of the transversal velocity effect, when the light emitter (or the receiver) is close to the gravitational lens with the distance between them being an impact parameter scale. The significant velocity effect is usually transient due to the motion of the gravitational lens relative to the light emitter or the receiver.
