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Objective the origin and the nature of the hodgkin and reed - sternberg ( h / rs ) cell of hodgkin ' s lymphoma ( hl ) has been attracting a lot of medical researchers engaged in studying it, for its character by scattered large atypical cells residing in a complex admixture of inflammatory cells. great improvement has been made since a new method of isolation of single h / rs cells from a frozen section had been set up by kuppers in 1994, and many studies have approved of the b - cell derivation of h / rs cell. lt has been reported that h / r - s cells might partly be originated from b - cell in our research before, but at the same time, we also found that only 18. 8 % of h / rs cells express cd20, 31. 3 % of immunoglobulin heavy chain ( igh ) rearrangement have been revealed
目的霍奇金淋巴瘤（ hodgkin ' slymphoma ， hl ）由於它的惡性腫瘤細胞? h rs細胞一般只佔腫瘤組織的極少部分（不到1 ） ，且散在分佈在背景細胞間，因此對于h rs細胞的來源和性質研究一直是人們探索的目標。 1994年德國科隆大學k ppers等發展了一種從冰凍組織切片上用顯微操作儀挑取單個h rs細胞的顯微切割方法進行h rs細胞基因分析后，人們對h rs細胞來源的研究有了突破性的進展，多數支持b細胞來源。我們的前期研究也支持部分h rs細胞為b細胞來源，但我們發現只有18 . 8的h rs細胞表達cd20 ， 31 . 3的hl檢測到igh基因重排克隆性條帶。
