Additionally, the larger the circumferential velocity component of hub leakage flow, the greater the deleterious effect of hub leakage upon the rotor flow
另外，葉根泄漏流的周向速度分量越大，泄漏流對轉子流場的不利影響也越大。 -
The main achievements are as follows : the theory models of defect mfl field are set up ; based on the magnetic dipole model and finite element model, the distribution of defect mfl field is simulated in the dissertation ; the component of flux density ( magnetic filed ) parallel to the surface of pipe is detected by a circumferential array of hall probes ; the factors including defect geometry parameters, defect surface angle and shape, pipe material, field intensity, vehicle velocity, background magnetization, operating pressure and remanent magnetization and so on influence the mfl signal characteristics
採用霍爾元件作為缺陷漏磁檢測傳感器，獲得管道軸截面漏磁場切向分量的漏磁信號；研究了缺陷外形尺寸、缺陷傾角和形狀、管道材質和磁化強度、檢測儀移動速度、管道背底磁場、管內壓力和剩磁對漏磁信號的影響。提出了各通道增益放大、各路漏磁信號偏離調整、波形微分、數字濾波和平滑等漏磁信號預處理方法；分析了等空間采樣的漏磁信號轉換為等時間采樣信號的必要性，研究了漏磁信號的小波去噪方法。 -
This phenomenon makes the circumferential velocity of the driven wheel be slower than the drive wheel ' s decrease the efficiency of the belt drive abrade the belt and shorten its life. so, it is very important for those who design and use it to know and understand qualitatively and quantitatively the phenomenon of elastic slippage
彈性滑動的存在使從動帶輪上的圓周速度低於主動帶輪上的圓周速度，帶傳動效率降低，帶磨損和工作壽命縮短，因此，定性和定量地認識和理解帶傳動中的彈性滑動現象對于帶傳動的設計和使用是十分重要的。
