摘　　要：该文采用变分法对双全同耦合单模光纤中基黑孤子的传输特性进行了研究 ,导出了孤子参数随传输距离演化的方程组 ,并讨论了初始相位差对孤子相互作用的影响 ,发现基黑孤子间的耦合相互作用比明孤子小 .In this paper, we researched the interaction of the fundamental black solitons between two same single-model fibers by variational method. We got the equations which show how the solitons' parameters change when the transmission distance changes. We also discussed how the initial phase difference influences the interaction between two solitons. We found it is true that the interaction between the dark solitons is less than that between the light solitons.
