摘要
本文用普通数学方法近似求解了含三光子吸收效应的ＮＬＳ方程，由此孤子解讨论了三光子吸收效应对孤子传输的影响．
In this paper the approximate solution to the NLS equation, inclucling three-photon absorption,by using common mathematics is given,and the solution of the three-photon absorption for influence of soliton propagation discussed in detail as well.
