首先研究了非线性饱和光纤中各阶孤子存在的幅值范围，与标准非饱和情况的非线性薛定谔孤子非常不同，即一阶孤子幅值范围是１．４≤Ｎ≤４．０，二阶孤子为４．０≤Ｎ≤７．０，三阶孤子为７．０≤Ｎ≤１５．０，并分析了各阶孤子的传输特性，最后研究了双一阶孤子相互作用的若干特点，明确了五个方面的特性。
Firstly, the amplitude range of each order soliton in a nonlinear saturated fiber is studied, which is very different from the nonlinear Schrödinger soliton in the standard non-saturation case. The first-order soliton amplitude range is 1.4≤N≤4.0, the second order The soliton is 4.0≤N≤7.0, the third-order soliton is 7.0≤N≤15.0, and the transmission characteristics of each soliton are analyzed. Finally, some characteristics of double-soliton interaction are clarified Five characteristics.
