本文用变分方法研究了由具有吸引力的玻色-爱因斯坦凝聚组成的亮孤子串的动力学。特别地，我们得到了两个孤子之间的相互作用势。我们还讨论了由于一维凝聚体的量子力学相位涨落而形成的孤子串。
We variationally determine the dynamics of bright soliton trains composed of harmonically trapped Bose-Einstein condensates with attractive interatomic interactions. In particular, we obtain the interaction potential between two solitons. We also discuss the formation of soliton trains due to the quantum mechanical phase fluctuations of a one-dimensional condensate.
