摘　　要：通过学生在学习狭义相对论的"同时性的相对性"时,对"同时"相对性的理想实验容易产生的一个问题,运用洛伦兹变换、类时类空事件的相关知识进行计算分析和闵可夫斯基空间进行几何描述,清晰直观解答疑难并得到判断事件时序能否颠倒的一般结论.When students learn the relativity of simultaneity of special theory of relativity, they are easy to raise a question about the ideal experiment of the relativity of simultaneity. This essay raises this problem and uses the knowledge of time-like and space-like events to calculate and analyze it, and uses Miukowskian space to describe it geometrically to answer the question clearly and visually. Moreover, it makes a conclusion on judging the chronological order of events can be reversed or not.
