从描述线双折射光纤中ｐｓ量级孤子脉冲的归一化ＮＬＳ方程出发，利用对称分步傅里叶变换计算方法，分析和归纳了正交极化孤子在双折射光纤中的碰撞数值特性，并对相关结论作了粗略探讨。
Starting from the normalized NLS equation describing the ps order soliton pulse in a birefringent fiber, the numerical simulation of the collisions of orthogonal polarized solitons in a birefringent fiber is carried out using a symmetric step-Fourier transform method. And made a rough discussion of the relevant conclusions.
