本文讨论了相对论教学中几个方面的问题，包括常见例子的问题，洛伦兹变换的方便形式，同时相对性例子在另一参考系的讨论，长度测量在另一参考系看到的现象，时间延缓及运动参考系各点时间不同和光的多普勒效应的简单推导.通过不同过程在不同参考系中的讨论，掌握在运动系讨论问题的方法，以及同一过程在不同惯性系内的不同表现，而所有现象的测量结论在洛伦兹变换下保持不变.

 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.
