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效應雖然不改變孤子能量,但會引起孤子峰
值的下降和寬度變寬,且在同一條件下, mnls孤子微擾理論得到的自頻移比nls孤子微擾理論得到的
更接近直接數
值計算結果。有限帶寬的頻率濾波也不引起mnls孤子初始中心、初始位相的改變,選取適當的頻率濾波器參數
值能使孤子的平均頻率穩定在初始平均頻率的紅側一穩定
值,抑制了自頻移,而且孤子的各物理量最後都穩定在一穩定
值,這些與nls孤子微擾理論都是類似的。有所不同的是,寬度為飛秒量級下, mnls孤子平均頻率的穩定
值更接近初始平均頻率,
更接近數

The advantages of the new method of calculating the vtec including : ( 1 ) because the instrumental bias is considered, the vtec ' s change going with time is closer to their real change. ( 2 ) with the precision of calculated the vtec improved, the vtec can reflect the increase of the vtec resulted from the solar flare
新的求解vtec的方法具有以下優點:考慮了gps衛星和接收機的儀器偏差的影響,計算的電子總量隨時間的變化
更接近電離層的實際情況;提高了求解電子總量的精度,計算出的vtec
值更能反映耀斑引起的電子總量的增加情況。

So, we must not only pay close attention to the absolute value of the position, but also to the relative value of it
因此,我們不僅僅要關注職位的絕對價
