Discussion on Time and Space Idea in Special Theory of Relativity

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.
