摘　　要：针对时间延缓和长度收缩这2个狭义相对论中最让初学者感到困惑的时空效应,通过对一个典型问题的多种求解分析,指出时间延缓和长度收缩实际上是洛伦兹时空变换下的2个特例,并进一步澄清了固有时2种表述.在利用时间延缓和长度收缩解决问题时必须要注意它们的适用条件.In view of the time delay and length contraction of the two special theory of relativity is the most confuse beginners of time-space effect,by analyzing a typical problem of solving,points out that the time delay and length contraction is actually under Lorentz space-time transformation of two special case,and further clarify the two expressions of fixed time.When trying to solve problems by using time delay and length contraction,must pay attention to their applicable conditions.

关 键 词：时间延缓 长度收缩 洛伦兹变换
