| 摘 要： | 利用变分法，通过非线性Schroedinger方程，导出光通信系统中非相干暗孤子间的相互作用，即通过非线性强度叠加产生的相互作用。结果表明：在两个非相干暗孤子之间存在排斥力，并且高阶色散效应减弱了非相干暗孤子的相互作用。这与相干暗孤子之间的相互作用结果一致。

| Abstract: | The interaction between two incoherent dark solitons is derivedfrom nonlinear Schr?dinger equation by variational aproach,i.e.interaction through nonlinear intensity overlap only.The result shows that there is repulsive forces between two incoherent dark solitons,and the high-order dispersion effect decreases the strength of the mutual interaction.The result accords with those in previously investigated coherent cases. |

| Keywords: | incoherent dark soliton variational approach interaction the high order dispersion effect |
