  1. Effects of different fuel - air ratios and different geometric parameters of dual - stage swirler ( such as inner diameters of the primary swirl and secondary swirl passages, outer diameters of the secondary swirl passages, vane angle of the primary and secondary swirler, the distance of the flare exit from throat etc ) on combustion performances are studied experimentally. the experimental results show that radial profiles of the outlet gas temperature 、 combustion efficiency 、 emissions of co2 、 co and nox and lean blowout are affected with different degrees by the different geometric parameters of dual - stage swirler and the arrangement of primary holes

    在不同油氣比下，不同的雙級旋流器幾何參數（例如:一級與二級旋流器出口內徑d 、葉片安裝角、二級旋流器出口外徑d 、二級旋流器的喉道到出口截面的距離l和喉道前後的圓弧半徑r以及主燃孔孔布局等）對單頭部環形燃燒室的出口溫度分佈、燃燒效率、貧油熄火油氣比以及污染物（ co _ 2 、 co和nox ）排放等燃燒性能的影響規律進行了研究。
  2. At the same instant martin sprang for him, clutching him by the throat with one hand in such fashion that mr. ends snow - white beard, still maintaining its immaculate trimness, pointed ceilingward at an angle of forty - five degrees

    馬丁立即跳了過去，一手揪住了他的喉嚨，揪得恩孜先生那依然一塵不染的白胡須向大花板翹起，呈四十五度角。
  3. Angle the mortars for the throat

    把追擊炮瞄準「咽喉」
  4. The flow through the throat - type energy dissipator and the right - angle energy dissipator are calculated by using the two - equation turbulence model, which is expansively used to simulate the flow field successfully. the principal content and the achievement are concluded as follow : as a kind of internal energy dissipator in which the turbulent flow is contracted and expanded abruptly, throat - type energy dissipator was regarded as one of the potential energy dissipator for its many advantages, such as stable flow pattern, simple structure, easily controllable flow parameter, and anti - cavitation property

    結合實體試驗，利用k -模型對當今尚處于起步階段的新型消能方式?洞塞消能工和直彎消能工進行了數值模擬研究，主要內容和研究成果如下： 1洞塞消能作為一種突縮突擴式的內流消能工，具有流態穩定、結構簡單、水流參數易於控制及防空化性能等優點，是一種很有發展潛力的消能方式。
  5. Characteristic of flow - fields at throat of oxidant nozzle, way to separate the equivalent three - nozzle, ejecting effect of different parameters and engineering situations have been demonstrated. effect of distance between secondary flows, the jet angle and the total pressure on the status of flow - fields, has been studied. reactive flow in a hyten nozzle with dimension that was primarily determined has been simulated

    研究了喉部引射主噴管的流場特徵、主噴管等效的三噴管分離方法和不同參數的引射結果以及相關的工程問題；同時還研究了hyten的流場特徵，不同副噴管間距、注入角度和總壓對流場參數的影響。
