液壓傳動.缸筒.裝有支撐環的活塞密封溝槽.尺寸和公差Clogged arteries propped open with drug - coated stents are less likely to re - clog than those supported by bare - metal stents
被藥物塗布支架撐開的阻塞動脈，應該比單用金屬架更能防止動脈血管的重新阻塞。Aiming at some reservoir characteristics of low porosity, extra - low permeability, low oil saturation, and low productivity as well as shallow depth in changxi area of ansai oilfield, through a large number of laboratory experiments and field tests, some suitable fracturing technology and operation parameters have been optimized, including low temperature fracturing fluids., propping fracture radius 、 pre - liquid and sand - fluid ratio
摘要針對安塞油田長西區低孔隙度、特低滲透率、低含油飽和度和淺層低產的油藏特性，通過大量室內、現場試驗研究，優選出適合的壓裂施工參數，包括低溫壓裂液、裂縫支撐半徑、前置液和砂液比。Abstract : in order to process signal in depth and to extract the fault feature from original signal in machinery diagnosis ， the graphical display algorithm that can keep the data length of wavelet transform results the same as that of original signal is used. the fault diagnosis of a bend axial piston pump via b - spline wavelet that has linear phase is provided. the results of study demonstrate that the new method has excellent feature and the weak fault signal can be extracted from the strong vibration background of the pump
文摘:採用具有線性相位的b樣條小波，應用圖形顯示演算法並結合小波變換快速演算法將信號分解到不同的頻帶上，且分解結果和原信號長度保持一致，可對信號進行深層次的處理，克服了傳統的信號處理方法不易提取微弱信息的不足.通過對礦用斜軸式柱塞泵振動信號的分析，分離出了配流副磨損、球鉸松動、缸體及泵軸支撐軸承的故障特徵，為液壓泵的故障診斷提供了依據，並為信噪分離、微弱信號提取及設備的早期故障診斷提供了一條有效途徑The thick part of the piston that holds the piston pin is the pin boss
