振蕩沖擊 的英文怎麼說
中文拼音 [zhèndàngchōngjī]
振蕩沖擊
英文
impulsing-
The poem swung in majestic rhythm to the cool tumult of interstellar conflict, to the onset of starry hosts, to the impact of cold suns and the flaming up of nebular in the darkened void ; and through it all, unceasing and faint, like a silver shuttle, ran the frail, piping voice of man, a querulous chirp amid the screaming of planets and the crash of systems
那詩以莊重的節奏振蕩起伏，伴隨著星際沖突的清冷的波濤萬千星宿的前進步伐和無數冷冰冰的太陽的沖擊，伴隨著最黑暗的空虛望的星雲的燃燒而在這一切之間，卻傳來了入類微弱細小的聲音，有如一支銀梭，不斷地無力地吶喊著，在星球的呼嘯和天體的撞擊聲中只不過是幾聲哀怨悲嗟的唧唧啾鳴。The shearing layer is carried by the jet and the eddy is formed because of the instability and selective amplification of shearing layer which will propagate to the downstream. as the eddy impacts the impinging wall, a wave of pressure disturbance with certain frequency is induced. this wave then propagates to the upstream with high speed, and results in the overlap and amplification of the waves when the frequencies of them are close with each other
當前噴嘴流束中的不穩定擾動波在穿過腔內的剪切層時，剪切層對其有選擇放大作用，形成渦環結構，剪切流動中渦環與碰撞壁撞擊，在碰撞區域產生壓力擾動波並向上游反射，在上游剪切層分離處誘發新的擾動的產生，當新擾動與原擾動匹配時，射流上游就被不斷地受到周期性激勵，腔內就產生流體自激振蕩並在後噴嘴出口形成脈沖射流。The limited - jerk control commands are designed by fixing on a jerk maximum to limit the varying ratio of the reference orders, then the optimal time delays are solved by minimizing the oscillation energy of flexible modes
通過確定最大沖擊值，對指令信號的時間變化率加以限制來設計有限沖擊控制指令，然後令柔性模態振蕩能量最小，計算濾波器的最優時滯。The paper is on how to set up lab platform of vapour spewing to uppercooling water surface to coagulate directly and to observe and analyse which vapour coagulate on the water surface, the results enable people to know the security system of nuclear power. the range of the pressure parameters of prz is from 0. 2mpa to 0. 6mpa, and the range of the initial temperature parameters of cmt is from 23. 5 to 78. 5, all of the testing points are 30 and there are fifty thousand testing data. many results of vapour spewing to uppercooling water surface vertically to coagulate can get. for example : coagulating can make the water of cmt surge forcefully when vapour spews to uppercooling water surface, too many vapour - bubbles come into being and strike the water of cmt owing to rupture continually, all these will strengthen the surge because of the vapour pressure of cmt
實驗中prz飽和蒸汽壓力變化范圍為: 0 . 2mpa - 0 . 6mpa ， cmt中水初始溫度變化范圍: 23 . 5 - 78 . 5 ，實驗中測試工況30個左右，實驗測試數據50萬余個，得出了很多與非能動安全系統相關的蒸汽垂直噴向過冷水表面凝結時的結論：蒸汽垂直噴入過冷水表面凝結時會造成cmt中液面的強烈波動和振蕩，產生大量蒸汽汽泡，汽泡不斷破裂對cmt中液體帶來很大沖擊，勢必引起cmt中液體的振蕩，造成cmt汽空間汽壓不均勻，加強cmt液體的振蕩和波動。With the model, direct starting, increasing voltage starting and current limit starting are studied and compared. the results of simulation suggest that current limit starting has good performance in starting current and torque limit and their oscillation restraint
從模擬結果可以看出，無論在減小起動電流沖擊、減小起動轉矩沖擊，還是在抑制電機電流、轉矩振蕩方面，採用限流軟起動方式都表現出良好的性能。分享友人
