摘　　要：从分析非惯性系之间相对运动的特征出发,建立了非惯性系之间的相对运动方程,推导出非惯性系之间相对运动的速度和加速度的变换关系,讨论了两个转动非惯性系之间的相对运动问题,得到了以地球为转动非惯性系的向心加速度表达式.研究表明:计算质点的速度时可以视地球为惯性参考系,但是计算加速度时必须视地球为非惯性参考系.Based on the analysis characteristics of the relative movement between the non inertial system,the equations of relative motion between the non inertial system are set,the transformation relations of the velocity and acceleration between non inertial system are deduced,and the relative motion between two rotating non inertial system is discussed,as also as the centripetal acceleration expression with the earth at the rotating non inertial system is obtained.Research shows that：when calculating the velocity of particle can see earth as inertial reference frame,but when calculating acceleration must see the earth as a non inertial reference frame.
