火山口火山爆發而形成的環形山或大山核心部分的崩塌而形成的環形山In this paper combustion performances of the single - head annular combustor with different swirler cups are investigated by experiment and numerical simulation. under different fuel - air ratios, profiles of exit temperature 、 combustion efficiency 、 lean blowout limit and pollutant emission are measured
在相同的雙級旋流器情況下，試驗分析不同油氣比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。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。Easy maintenance counts at it s fourth advantage : for the motor and controller used are all imported from japan, having much less malfunction, timely charge, oil cleaning and day - day s simple maintenace according the operation manual is enough ; the airboat can make not only advertising but also much other works, such as photos taking, kinescoping when installing the camera on the hung house, through to the management and planning of the earth source, monitoring the pollution of the environment, estimating the growing state of the crops ect.,
維護簡便是它的第四大優點由於遙控飛艇所使用的發動機遙控器均為日本進口，故障率低，平日只需按說明書要求定時充電，清洗化油器和火花塞及日常的一些簡單保養，維修工時少且不繁雜。遙控廣告飛艇不僅能做廣告，還能做許多相關的業務，航拍航攝在飛艇的吊倉上加裝照相機或攝像機就可進行空中拍攝，業務范圍可大到土地資源的管理與規劃，環境污染的監測，農業生長形勢的評估。分享友人
