摘　　要：根据物体运动的相对性原理可知选择不同的参考系便有不同的运动周期.已知太阳日、朔望月和恒星年的值,由相对运动的角速度矢量关系求得恒星月和恒星日的值,由恒星日推出地球的自转角速度.According to the relative principle of motion of objects,it can be seen that choosing different reference systems will have different motion cycles.The values of solar day,lunar month and sidereal year are known,and the values of the sidereal month and the sidereal day are obtained from the angular velocity vector relation of relative motion.The earth′ s rotation angular velocity is deduced from the sidereal day.

关 键 词：周期 参考系 恒星月 恒星日 角速度
