解釋
反饋諧振腔-
Second, we compute the self - impedance through cavity modal theory and mutual impendance based on reaction theory respectively. then the generalized impedance matrix that reflects the effect of mutual coupling is formed. at last, the effect of mutual coupli ng on 2 - d doa estimation algorithms is investigated and two efficient methods of mutual coupling compensation are proposed
本文首先對兩種二維doa估計演算法? ssm法和二維酉esprit法的性能進行了比較，用空域平滑演算法解決了相干源的二維doa估計；其次運用腔模理論計算微帶天線的自阻抗，用反應原理計算微帶天線間的互阻抗，進而形成計入互耦影響的廣義阻抗矩陣；討論了互耦對二維doa估計的影響，提出了兩種互耦補償的方法。 -
It is found that the liquid kerosene of injection upstream cavity could finish the process of atomization and evaporation in short distance, and enter into cavity through convection. aft wall is the primarily area of flame holding in cavity, and the only area when near the lean blowout limit, flame in area of fore wall are spread from it. cavity shear layer in reaction flow angle greatly to the main flow direction, and couldn ’ t reattach to aft wall anymore, it appears great difference in characteristics of cavity flowfield between non - reaction and reaction state
研究發現:凹腔上游噴注的液體燃料能夠迅速霧化、蒸發，並在較短距離內依靠對流輸運過程進入凹腔內部;凹腔後壁始終是凹腔火焰駐留的主要區域，在貧油極限時，也是唯一區域，並存在明顯的火焰由後壁向前壁的傳播過程;燃燒狀態下的凹腔剪切層以較大角度向下游主流發展，不再附著于凹腔後壁，與冷流中的凹腔流場特徵相差較大。 -
The gas sources that we used are trimethylgallium ( tmg ) and 99. 9999 % purity nitrogen, which were fed into reaction chamber and resonance cavity respectively. the highly dense ecr plasma up to 1011cm - 3 was created in the resonance cavity and introduced to the next reaction chamber by the force of divergent magnetic field. consequently, gan thin film was grew on the substrate sapphire ( 0001 ) placed in the downstream
實驗採用有機金屬三甲基鎵氣源（ tmg ）和99 . 9999純度的氮氣，在ecr - pecvd150裝置共振腔內電子迴旋共振吸收微波能量產生的高密度ecr等離子體在磁場梯度和等離子體密度梯度的作用下向下級反應室擴散，在放置於下游區樣品臺上的- al _ 2o _ 3襯底表面附近發生物理化學反應沉積成gan薄膜。 -
The flame holding technology based on cavity in supersonic combustion was studied systematically and comprehensively. the interaction between gas / liquid injection and cavity flow were studied in non - reaction flows
論文選取基於凹腔的超聲速燃燒火焰穩定技術為研究對象，對凹腔燃燒流動過程和凹腔火焰穩定器性能進行了全面深入研究。
