    該測量儀與位移傳感器及前置器配合使用，能夠在線監測包括振動峰峰值和平均值等振動信號量，同時測量儀可以自動檢測傳感器安裝距離，在危險的情況下可以根據事先設定好的報警值進行報警。
  4. 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，更接近數值計算結果。
