自变陡 meaning in English

self-steepening

It is found that the peak power of pump pulse is important and the fourth and fifth dispersions are crucial to flatly wideband sc generation from the fiber . the results show that the higher - order nonlinear effects on sc generation can be ignored
研究结果表明，泵浦脉冲峰值功率对sc谱的产生有着重要影响，光纤的四阶、五阶等高阶色散的综合作用对sc谱的形成起决定因素，高阶非线性效应( raman自散射和自变陡效应)的影响可以忽略。
Three shaped profiles ( parabola , linear , and exponential ) have been considered . the exponential dispersion profile fiber loop is optimal for the propagation and compression of picosecond pulse . on the contrary , the parabola dispersion profile fiber loop is optimal for femtosecond pulse due to the high order effects such as the third order dispersion ( tod ) , stimulated raman scattering ( srs ) and self steeping ( ss )
( 3 )研究不同色散递减类型(抛物线递减、线性递减、指数递减)光纤构成的环形腔中传输的特性，发现其色散曲线为指数递减型光纤有利于皮秒光脉冲的传输与压缩；而对于飞秒脉冲，由于三阶色散( tod ) 、脉冲拉曼自散射( srs )及自变陡( ss )等高阶非线性效应的影响，情况恰恰相反；色散曲线为抛物线递减型的光纤构成的光纤环最有利于脉冲传输与压缩。
