環形孔道 的英文怎麼說
中文拼音 [huánxíngkǒngdào]
環形孔道
英文
annulus-
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。Considering of the problems exist in practice, large orifice discharge principle is employed to study the pressure distribution of ring runner system, the even ab lity for discharging of gates, the relationship of flow with the position of spr ue and the type of gates. a new design idea about circular runner system of cast is proposed
根據生產中存在的問題，用大孔出流理論研究了環形橫澆道系統的壓力分佈、內澆道出流均勻性及流量與直澆道引入位置和內澆道引入方式之間的關系，提出了圓形鑄件環形橫澆道系統新的設計思想。Taking the traffic load as moving point load, the deformation characteristics of longitudinal section of pavement and composite foundation under moving point load are analyzed, considering the effect of pore pressure, traffic velocity, parameters of pavement structure and subgrade. finally, two examples of pavement section and soft subgrade, longitudinal section of airport runway and composite foundation are calculated
