Example Sentences:

	1.	The equation including the nonlinear dispersion , i . e . the modified nonlinear schrodinger ( mnls ) equation , is a better model . in this thesis , we take mnls solitons as a model for femtosecond soltions . then based on the recently developed direct perturbation theory for perturbed mnls equation , we study the raman self - frequency shift of femtosecond solitons and its suppression by the means of frequency filters . for this purpose , first , we define the physical parameters of mnls solitons ; next , through the direct perturbation theory for perturbed mnls equation , under adiabatic approximation , we obtain the evolving parameters of mnls soliton on our questions and then choose the parameters of frequency filters based on it ; at last , we directly numerically simulated our questions by split - step fourier ( ssf ) method after improving the arithmetic of the differentiation of the nonlinear item for satisfying mnls equation 本论文以mnls孤子作为光纤飞秒孤子的模型，通过新近建立的mnls孤子直接微扰理论，研究光纤中由拉曼效应引起的飞秒孤子在传输中的自频移，以及通过频率滤波对自频移的抑制。为此，首先给出描述mnls孤子的各物理量，然后用mnls孤子直接微扰理论，解析地得到这些问题绝热近似下的孤子参数演化，并由此选择频率滤波的参数，最后用分步傅里叶方法，在对非线性项微商的算法做出了适合于mnls孤子的改善后，对拉曼效应及频率滤波进行了直接数值模拟，其中频率滤波参数用微扰理论确定。
	2.	Our treatment shows in the raman effect case , mnls solitons , the same as nls solitons , keeps its energy , initial center and initial phase unchanged . however , the raman effect , not the same as nls solitons . reduces its amplitude , widens its width and under the same conditions , the self - frequency shift of mnls soltions is closer to the result of numerical simulation . in the raman effect together with frequency filters case , mnls solitons , the same as nls solitons , keeps initial center and initial phase unchanged and bandwidth - limited frequency filters can make the mean frequency of mnls soltion stand a steady value at the red side of the initial mean frequency , i . e . suppress the self - frequency shift of mnls soltions . and that , the other physical parameters of mnls soltion last stand a steady value . however under the same conditions , the steady value of the mean frequency of mnls soltions is closer to the initial mean frequency and the result of numerical simulation 有所不同的是， raman效应虽然不改变孤子能量，但会引起孤子峰值的下降和宽度变宽，且在同一条件下， mnls孤子微扰理论得到的自频移比nls孤子微扰理论得到的更接近直接数值计算结果。有限带宽的频率滤波也不引起mnls孤子初始中心、初始位相的改变，选取适当的频率滤波器参数值能使孤子的平均频率稳定在初始平均频率的红侧一稳定值，抑制了自频移，而且孤子的各物理量最后都稳定在一稳定值，这些与nls孤子微扰理论都是类似的。有所不同的是，宽度为飞秒量级下， mnls孤子平均频率的稳定值更接近初始平均频率，更接近数值计算结果。
