Contemporary college students are interested in relativistic theory,and hope to do some research on general relativity.However,the principle of special relativity is the basis of general relativity,and students should master the theory of special relativity firstly.Unfortunately,in the practice of teaching,it is found that the beginners are harder to understand the space-time view of special relativity.In this paper,two typical exercises are taken as an example,which are solved on the K system and the K'system,to analyze the space-time coordinates of the events and solve the space-time problems of the special relativity.The two methods confirm each other,which makes it easier for students to master the method of solving space time problems in special relativity.In addition,this paper also puts forward the problem which is easy to be neglected when solving the space-time problem by using relativistic velocity,analyzes the cause of the error,and gives the correct solution.
