关于狭义相对论中时空问题的讨论

Discussion on Time and Space Idea in Special Theory of Relativity

狭义相对论明确指出同时性、时间和空间的测量是相对的,与物体的运动状态或与参考系的选取密切相关,并以此建立了相对论时空观.基于狭义相对论中时空概念的关联分析,讨论了解决时空问题的思路和方法,指出了"同时性的相对性"是理解和认识相对论时空观的基础,有利于解决大学物理教学的重难点问题.

It is explicitly pointed out in the special theory of relativity that the measurements of simultaneity,time and space are relative and closely related to the motion state of objects and/or the selection of the referencesystem,based on which,the theory of relativity time and space is established.By analyzing the relationship of timeand space idea in the special theory of relativity,the clues and analytic method of solution the time-space pointsdiscussed,pointing out that the‘relativity of simultaneity’is the basis of understanding the idea of time and spacein the theory of relativity,which can help to solve the key and difficult points in college physics teaching.
