摘　　要：推导、讨论了在既有平动又有转动的坐标系下的两体相对运动的动力学方程和能量方程的表达式,结果说明动力学方程和能量方程分别可视为质心系的牛顿第二定律和动能方程.通过举例说明应用.The kinetic equation and equation of energy of two body relative moving are derived and discussed in both translation and rotation of the coordinate system, It shows that the meaning of the equation is explicated. The kinetic equation can be regarded as Newton ＇ s second laws of motion, and that of energy can be equation of particle reference frame relative to the center of mass reference frame through exampies of applications.
