自由偶极子运动规律研究

摘要

The interaction energy of free dipole made up of positive and negative ions is discussed,and the motions of the dipole with this forces acting on it are analyzed.After solved the motion equations,we find the motion of the free dipole is the superposition of uniform rectilinear translation and simple harmonic motion.And its mass center makes uniform rectilinear translation.In mass center coordinate,the ions make the simple harmonic motion near their equilibrium positions.%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,其质心作匀速直线运动,在质心系中,两离子分别在其平衡位置附近作简谐振动.
