| 摘 要： | 用最小作用量原理导出了非线性Schr?dinger方程两个孤子间的相互作用它作为孤子间距△与初位相差δ的函数揭示出来，当两个孤子δ<π/2时相互吸引,δ>π/2时相互排斥，δ=π/2时几乎不存在相互作用；相互作用的大小随△的增大而指数地衰减.本文的结果与实验的定量比较表明两者符合甚好

| Abstract: | The interaction between solitons of the nonlinear Schr?dinger equation is derived by the least action principle approach as a function of the soliton' s separation △ and their initial relative phase δ. The equation shows that two solitons with δ<π/2 attract with each other while those with δ>π/2 repel, and there is almost no interaction when δ=π/2, and that the interaction decreases exponential-ly as △ raises. The results obtained is well consistent with that of the experiment quantitatively. |
