摘　　要：研究了弯曲时空中平面运动刚体的动力学协变方程.给出了Minkowski时空中平面运动刚体动力学方程的协变形式.利用间隔是广义坐标变换下的不变量,得到弯曲时空中任一点运动标准钟与坐标钟的关系,建立了弯曲时空中平面运动刚体动力学方程的广义协变形式,并对其结果进行了讨论.The covariant equation of plane motion rigid body in curved space-time is stuched. The covanant equation of plane motion rigid body in Minkowski space-time is given. According to the interval, which is an invariant in the transformation of the generalized coordinate, the relation of the motive standard clock of any dot to the coordinate clock in curved space-time is found. At the same time the covariant equation of plane motion rigid body in curved space-time is constructed. Finally the result is discussed.
