语境意义偏向性对汉语歧义句意义建构的影响 - 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。
