摘要
作者在考虑非线性损耗的同时，还考虑了介质的横向不均匀性及非线性项的延时响应效应的前提下，采用“慢性包络近似”推导光学孤子在单模光纤中的非线性演化方程。结果表明，如果从推导之始就考虑线性损耗效应，则方程中某些项的系数会因线性损耗的引入而改变。
The basic equation of soliton in single mode fiber evolution is deduced by “Slow Envelope Approximation”.The results show that if at the very beginning of inference, the linear loss is considered,the coefficient of the equation will change due to the linear loss.
