| 摘 要： | 指出用传统的"平行线"模型和光速有限来解释光斑移动现象,当将情况推广到极限时,会出现一些局限,并提出了一种新的与实际情况更符合的"同心圆"模型,由此可以解释光斑移动现象.

| Abstract: | Using the "parallel line" model with the limit of velocity of light to explain the phenomenon of light spot movement,we generalize the situation to the limitation,however,it results in some localizations.A new "concentric circles" model is proposed,which is much more accord with the actual condition,and can explain the phenomenon of light spot movement. |
