粗泵 的英文怎麼說
中文拼音 [cūbèng]
粗泵
英文
roughing pump-
When the thickness increases up to a critical value, about 30 nm, the spotty rheed pattern gradually changes to streaky pattern, and the rheed oscillation curve appears. the rheed pattern of the ultra thin lno film deposited in the relatively high oxygen pressure is streaky pattern. with pumping the oxygen pressure to the relatively low value, the streaky rheed pattern gradually changes to spotty one
我們發現在較低的真空度下，即氧分壓處於2 10 - 4pa和3 10 - 3pa之間， lno晶格中的一個o2 -將會轉移兩個電子給兩個ni3 + ，並且移動到薄膜表面形成o2被泵抽走，從而導致鈣鈦礦結構的垮塌，其相應的rheed圖樣呈現出清晰而明亮的點，表明表面為較為粗糙的三維島狀結構。This system is based on the programmable controller and dh + network ( data high way plus network ), and it can supervise and control the whole flow of the seawater injection. as the primary device in the system, programmable controller implement the flex logic control for the flow and can collect the data in the flow to establish the control center
該系統基於可編程式控制制器及dh +網路，實現了對注海水全流程（海水提升、海水粗濾、海水加藥、海水沉降、海水細濾、海水脫氧、氣水分離、注水罐、注水泵）的實時監控。The dream is to launch a medical reolution in which ailing organs and tissues might be repaired ? not with crude mechanical deices like insulin pumps and titanium joints but with liing, homegrown replacements
這個夢想的實現將發起一場醫學革命，從而使損傷的器官和組織可以得到修復，不再使用那些類似於胰島素泵或是鈦金屬關節這樣粗糙的機械設備，而是使用具有生命力的，自身合成的替代品。Measures for further developing concrete mix design were presented based on above work. for example, adopts pfca as an index in designing durability of concrete, uses mortar slump flow test to select cements and water - reducers and to measure saturation dosage of water - reducer in mortar and then determine optimum dosage of it in concrete, uses bar - slump test to determine stability and fluidity of fresh concrete, and consequently, the workability of high fluidity and high stability concrete such as pumped or self - compacting concrete can be designed by adopting proper cfvm determined in terms of rheological properties of designed mortar measured with cone - based rheometer
如採用粗集料破碎率作為耐久性設計的一個指標；採用砂漿坍落擴展度試驗選擇水泥和減水劑，確定砂漿中減水劑的飽和摻量，並通過上述數學模計算混凝土中減水劑的飽和摻量，以此為參照確定最佳摻量；採用障礙坍落度試驗確混凝土的穩定性和流動性，結合由漏斗式砂漿流變儀測定的砂漿流變性能確定合理的砂漿填充系數，從而實現對高流動性高穩定性要求的混凝土（如泵送和免振自密實等）的工作性設計。Although the technology of vibration diagnosis has acquired some achievement, on the occasion of having several faults, the method has some trouble that cannot be solved. to solve this problem, some methods i. e. rough - set theory and genetic algorithm have to be used to identify specific fault and decide which pump valve has fault
這種振動診斷技術雖然取得了一定的成果，但是在多個泵閥同時發生故障的場合，這種方法遇到了無法解決的難題，使之不得不求助於粗集理論、遺傳演算法等數據處理方法來分辯故障類型和判斷故障具體發生在哪一個泵閥上。分享友人
