  1. Experimental research on low specific speed roto - jet pump

    低比轉數旋噴泵的試驗研究
  2. The roto - jet pump is a new kind of very low specific speed pump which is developed in recent years. it is always used in carbin black, food production, chemical industry and deep well mining system to supply the steady outflow with low flux and high pressure

    旋轉噴射泵是近些年才發展起來的一種極低比轉數泵，主要用在碳黑、食品、化工以及深井采礦系統中用以提供小流量高水頭的穩定出流。
  3. Investigation on low - speed vector control of adjacent synthetic jet actuators

    相鄰合成射流激勵器低速射流矢量控制研究
  4. The main relative systems of heavy - hard rainfall in northeast plateau are western pacific subtropical high, south asia high, low latitude systems, upper level jet ( ulj ), low level greater wind speed axes, westerly trough and plateau trough, low level vortex, cold frontal, occluded front in qinghai lake, mesoscale low pressure, heat low - pressure in qinghai, shear line and convergence line, mesoscale cloud cluster, etc. the west subsidiary model of south asia high is the main circulation type of heavy - hard rainfall in this area

    3 、西太平洋副高、南亞高壓、低緯系統、高空急流、低空大風速軸；西風槽和高原槽、低渦、冷鋒、青海湖錮囚鋒以及中尺度低壓、青海熱低壓、切變線與輻合線、中尺度雲團等系統是高原東北部地區大到暴雨的主要相關系統。 100hpa上的南亞高壓中心強度加強，位置東西擺動預示高原地區將有降水產生，中心強度減弱，降水過程結束。南亞高壓西部副型是高原東北部地區大到暴雨的主要流型。
  5. A new type of very low specific speed pump ? roto - jet pump is presented for low flowrate and high head transportation, which is introduced at the end of the thesis

    論文最後主要研究了一種隸屬于極低比轉數離心泵范疇的新型泵? ?旋噴泵，它是一種新型的石油化工用泵，具有流量小、揚程高、流量揚程曲線平緩的特點。
  6. However, by comparison with flap nozzle servo valve which has been used widely and popularly by now, the torque motor of jet pipe servo valve has a larger rotary inertia. this causes low natural frequency of servo valve, and thus the response speed of jet pipe servo valve is slow. moreover, the jet pipe of servo valve has large flexibility, and it is easy to excite oscillations and noise in the valve, which is named self - excited oscillations and noise

    然而與目前普遍使用的噴嘴擋板伺服閥相比，射流管伺服閥的銜鐵組件轉動慣量大，導致力矩馬達部分固有頻率低，從而響應速度慢，此外，射流管供油管柔性大，容易產生自激現象，這些缺點都使得射流管伺服閥的動態特性差，從而影響了它的工作性能。
