球形塞 的英文怎麼說
中文拼音 [qiúxíngsè]
球形塞
英文
ball plug-
The advent of balloon angioplasty reduced the intrusiveness for certain patients ; a balloon was fed along a catheter to the blockage, then expanded to crack and compress the plaque, leaving a wider conduit for blood flow
氣球血管造形術則降低了手術侵入程度：氣球沿著導管送進堵塞的血管區域，然後氣球會充氣，壓碎並壓緊粥狀硬化斑，以利血液流通。Figuratively, one may imagine the radiation of such a spherical maser as resembling a little hedgehog.
可以很形象地把這種球狀脈塞源的輻射想象為一個小刺蝟球的樣子。Although some are used during heart bypa surgery, most coronary stents are i erted as a follow - up to angioplasty, a le invasive procedure in which the blockage is cleared from i ide the artery by inflating a balloon
雖然也有一些被用於心臟搭橋手術，但大多數心血管支架用於血管成形術的后續治療器械，這樣可以使通過給氣球充氣從動脈內部清除動脈阻塞的過程更不易擴散。Although some are used during heart bypass surgery, most coronary stents are inserted as a follow - up to angioplasty, a less invasive procedure in which the blockage is cleared from inside the artery by inflating a balloon
雖然也有一些被用於心臟搭橋手術，但大多數心血管支架用於血管成形術的后續治療器械，這樣可以使通過給氣球充氣從動脈內部清除動脈阻塞的過程更不易擴散。In this paper, we study and analysis the base distribution in human dna sequences. on the basis of the distribution sphere whose radius equal to 1 / 4 by zhang et al. expounded, with the method of plane mapping figure studying 6000 human dna sequences, and according to the figure of sierpinski gasket ' s patch and the brillouin zones of the face - centered cube, we obtain two new distribution figures, one is the frustum - octahedron, another is the regular - octahedron
我們在zhangetal .提出的人類dna序列的堿基分佈為半徑是1 / 4球分佈的基礎上，用平面投影圖的方法研究和分析了6000組人類dna序列的數據，並且根據塞爾賓斯基鋪墊的補形和面心立方的布里淵區圖形提出了兩種新的分布圖，一種是正八面體，另一種是截角八面體（十四面體） 。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Manually operated ball valves and closed bottom taper plug valves for gas installations for buildings

為了求得孔隙度的近似界限，斯里西特以及后來的哥拉登和弗雷塞計算了均一球粒在不同堆積形式f的孔隙度。Matese studied 82 comets from the oort cloud and found common elements in the shape of their orbits that could only be explained if they had been influenced by the gravitational pull of an object several times the size of jupiter and existing about 25, 000 times farther from the sun than the earth
馬泰塞研究了來自奧爾特雲的82顆彗星，發現在它們軌道的形狀上有共同的因素，那只有在它們是被一個數倍大於木星的天體的引力作用所影響，且這個天體距太陽的距離比地球要遠25 ， 0000倍的情況下才能解釋。Manually operated ball valves and closed bottom taper plug valves for gas installations for buildings ; german version en 331 : 1998
