摘　　要：讨论了由正负离子实组成的自由偶极子的相互作用能,分析了仅在该作用下偶极子的运动,求解其运动方程,得出自由偶极子的运动为匀速直线运动和简谐振动的叠加,其质心做匀速直线运动;在质心系中,两离子分别在其平衡位置附近作简谐振动。This article discusses the interaction energy of free dipole which is made up of positive and negative ion core,analyzes the motion of the dipole under this action,and solves its motion equation.It is concluded that the motion of free dipole is the superposition of uniform rectilinear motion and simple harmonic motion,and its mass center makes uniform rectilinear motion.In the centre of mass system,two ions separately make simple harmonic motion near their equilibrium positions.

关 键 词：自由偶极子 简谐振动 质心系
