在反常群速度色散区，在光克尔非线性的影响下，单模光纤支持初始孤子脉冲的稳定传输。本文提出了一种奇异微扰方法来研究作用在这种初始孤子脉冲上的各种微扰。与以往的微扰理论相比，这种方法摆脱了对复杂的逆散射变换的依赖。
In the anomalous group velocity dispersion regime, under the influence of optical Kerr nonlinearity, the monomode optical fiber supports stable propagation of an initial soliton pulse. In this paper, we present a singular perturbation approach for the study of various perturbations acting on this initial soliton pulse, In contrast with the previous perturbation theory for this subject, this approach gets rid of dependence on any tool of the sophisticated inverse scattering transform.
