  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d 、葉片安裝角、二級旋流器出口外d 、二級旋流器的喉道到出口的距離l和喉道前後的圓弧r以及主燃孔孔布局)對單頭部環形燃燒室的出口溫度分佈、燃燒率、貧油熄火油氣比以及污染物( co _ 2 、 co和nox )排放燃燒性能的影響規律進行了研究。
  2. Comparing our results with that of predecessors, we find that ( i ) there indeed exists a parameter ( impurity bohr radius ajm ) on which the impurity binding energy has strong dependence ; ( ii ) the virial theorem value is non - constant but approach 2 from above when the well width is smaller or larger

    計算結果表明:的確存在一個參數(雜質有玻爾)可用來完全確定束縛能的值,而不必考慮的形狀和尺寸;體系的維里定理值並不於常數,而是隨雜質有玻爾的變化而變化,在阱寬較小和較大時,維里定理值都趨于同一值2 。
