When pursuing femtosecond-scale ultrashort pulse optical communication, one cannot overlook higher-order nonlinear effects. Based on the fundamental theoretical model of the variable coefficient coupled high-order nonlinear Schr¨odinger equation, we analytically explore the evolution of optical solitons in the presence of highorder nonlinear effects. Moreover, the interactions between two nearby optical solitons and their transmission in a nonuniform fiber are investigated. The stability of optical soliton transmission and interactions are found to be destroyed to varying degrees due to higher-order nonlinear effects. The outcomes may offer some theoretical references for achieving ultra-high energy optical solitons in the future.

采用化学气相沉积法(CVD)以二茂铁为催化剂,乙炔为碳源制备了Fe/洋葱状富勒烯(Fe/onion-like fullerenes,Fe/OLFs),通过场发射扫描电子显微镜(FESEM)、高分辨透射电镜(HRTEM)和X射线衍射(XRD)分析了Fe/OLFs的晶体结构和形貌。结果表明,所制备的Fe/OLFs是由同心封闭壳层组成的准球形颗粒,其层间距为0.349nm,与石墨的层间距0.336nm相接近。在MRS-10A型四球摩擦试验机上考察了Fe/OLFs作为长城牌SE级15W-40汽油机油的添加剂的摩擦性能。摩擦试验表明,Fe/OLFs作为润滑油添加剂表现出优良的抗磨减摩性能,并能显著改善基础油的承载能力,当添加量为0.02%(质量)左右时,润滑油的抗磨减摩性能最佳,与基础油相比摩擦系数下降40.8%;在相同的质量分数和载荷下Fe/OLFs作为润滑油添加剂在减摩性能上均优于CNTs。
