摘　　要：基于光孤子脉冲在光纤中传输所遵从的非线性薛定谔(NLS)方程,在忽略三阶以上色散效应、自陡和自频移效应并通过对方程中相关参量的无量纲化处理之后,得到了总光元场满足的微扰NLS方程,分析了孤子相对间距与初始相位对其传输的影响。According to the nonlinear Schrdinger（NLS）equation which the optical soliton pulse transmiting in the optical fiber obeys,the perturbation NLS equation of total light field is obtained.In the process to deduce the equation,it is neglected the third-order chromatic dispersion effect,self-steep and self-frequency-shifting effect and the equation parameter is zero dimension processed.The relative space and the starting phase which influence the transmission of optical soliton are also analyzed.
