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。 -
Analysis indicates the " low pressure closed reticular flow region " results in the non - equilibrium of pressure along the primary jet ' s orifice. to obtain as large vectoring angle as possible, the optimal ranges of angles, frequencies, velocity amplitudes, and distances from the microjet actuator to the primary jet exit were discussed. the relationship between the vectoring angle of the primary jet and the phase - difference of two adjacent actuators was analyzed
分析了「拉」模型單作動器模式下，微射流作動器的入射角度、驅動頻率、速度幅值及與主射流間的距離對主射流偏轉程度的影響，並確定了作動器工作參數的最佳范圍;分析了「拉」模型雙作動器模式下，不同的相位差對主流偏轉程度的影響。 -
At the soonest approach concerned the theoryon after liberation was producer goods precedence growth, two greater part proportional relation and others, present research tend to industrial structure fluctuant resource allocation effect, industrial policy, traditional industry ' s adjustment and quantification research. industry organization theory is based on microeconomics, orthodox industry organization theory ' s basic feature is scp analyses paradigm, primary school has harvard as well as non - mainstream ' s chicago school, innovation school and neo - austrian school. hotspots in our country recent years are enterprise size, industrial concentration, market structure, as well as relation to performance, entering and exit mechanism and industrial system policy. this article takes over evolutionary economics ' s analytical approach to analyse institution and technology change, which may affect manufacturing industry, and using evolutive viewpoint to research competition, regional cooperation. based on industrial economics ' s theory, the artical puts forward that manufacturing industry take the leading function in economic structure transformation, manufacturing industry ' s laging is maxima drawback for the agro - industry change, and others
產業結構理論早在威廉?配第的著作中已有論及，要點是產業間的相對收入差異導致勞動力的部門流動；后來又有關于勞動力在三次產業間移動趨勢的研究，產業結構演替規律的分析，工業化過程與后工業化社會，工業結構的高加工度、高技術化及產業結構軟化等問題的研究，我國建國後有關的理論最早探討生產資料優先增長、兩大部類比例關系等，目前的研究則趨于對產業結構變動的資源配置效應、產業政策、傳統產業調整進行定量化研究。產業組織理論以微觀經濟學為基礎，正統的產業組織理論的基本特徵是scp分析範式，主要有哈佛學派和芝加哥學派、新制度學派和新奧地利學派。 -
Abstract : optimum distances between primary nozzle exit and mixing tube inlet, static pressure recovery of the mixing flow in mixing tube 、 total pressure distributions at the exit of mixing tube 、 pumping coefficients and total pressure losses of the exhaust ejector systems with four different types of primary nozzles have been measured in the experiments
文摘:對4種主噴管組成的排氣引射系統的引射系數和總壓損失、各主噴管出口與混合管進口之間的最佳間距、混合氣流在混合管內的靜壓恢復及混合氣流在混合管出口處的總壓分佈等進行了測量和對比。 -
How to improve the three primary colors led light source cavity, polarizing beam splitter system of civil lcos hmd is discussed in this paper. in addition, a new eyepiece optical system with wide fov ( field of view ) 、 big exit pupil 、 long eye relief is also designed by an optical design program named zemax. the result is very successful
本文對民用lcos頭盔微顯示器的led三基色光源及其腔體、偏振分光系統進行了改進，藉助zemax光學設計軟體輔助設計出了大視場、大出瞳直徑、長出瞳距離的目鏡放大光學系統，獲得了十分理想的效果。 -
Much research has been done on the performance evaluation of funds, and some experts abroad have set up a mature and systemic theory system through decades of hard work. but related research in china is still very primary because the securities investment funds appear and exit in china for a short time. much of them focused on the closed funds, because the closed funds appeared longer time than the open - ended funds
對于基金管理公司而言，通過對基金業績的分析，不僅可以對基金經理的努力程度和業績水平給出具體的量化評價，還可以依此來分析所實施的投資計劃是否達到或超過了投資目標，發現投資計劃的不足，判斷基金投資策略在市場中的適應能力，總結管理成功的經驗，提高公司的經營管理水平。
