摘　　要：运用变分法导出五阶非线性作用下孤子的参数演化方程组,研究五阶非线性耦合光纤中孤子的传输特性,讨论五阶非线性效应对孤子的振幅,频宽,啁啾,频率,中心位置及相位的影响.In this paper, the evolution equations of the parameters of the optical soliton pulses were derived by means of variational method, in order to investigate the influence of the fifth-order nonlinear effect on the transmission properties of optical soliton in the coupling fiber, and the effects of the fifth-order nonlinearity were discussed on amplitude, frequency band width, chirp, frequency, center position and phase.
