- The main results of this work are as follows : 1
~ 7be在土壤剖面中的含量随土壤深度的增加呈指数递减。 - Time domain noise is simulated by the mathematical pseudo uniform or normal random variable and coupled to deterministic signals such as rectangular ( rect ) , triangular ( tria ) , unit step exponential ( uexp ) , even exponential ( eexp ) , or gaussian ( gauss ) pulse voltages in finite number of time samples in finite time period
用数学类真均匀或常态随机变数模拟时域杂讯，与定然时域讯号如，方形、三角、指数递减、或高斯等电压脉波在有限时域?围之有限个时域取样结合。 - These characteristics are in sharp contrast to what one observes in the traditional models for network traffic , models that are based on an exponentially fast decaying correlation function , implying that time - aggregation time series quickly results in white noise traffic characterized by the absence of any temporal correlations
这些新发现的网络业务量行为特征与传统业务量模型行为特征有极大的不同? ?传统业务量模型一般假定指数递减的相关结构的存在，这意味着随着时间聚合时间序列将演变为白噪音，即时间相关性渐进地消失了。 - 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。
