Abstract:

 This paper discusses several problems in the teaching of relativity，including

questions in common examples，convenient form of Lorentz transformation，discussion on the example

of simultaneous relativity in another frame of reference，the phenomenon of length measurement seen

in another reference frame，delay of time and the time of each point in the motion reference frame

are different，and a simple derivation of Doppler effect of light is preformed. Through the

discussion of different processes in different reference systems，master the method of discus- sing

problems in motion reference frame，and the different performance of the same process in

different inertial frames，the measurement results of all phenomena remain unchanged under Lorentz

transformation.

Key words: special relativity, space time view, Doppler effect of light
