  1. Using method of oil - flow visualization techniques and measuring pressure distribution along airfoil chordwise and spanwise studies have been down for sidewall boundary - layer displacement effect in two - dimensional wind tunnel. three different chord models were tested in two different wind tunnel. in order to clarify the sidewall effects and study method of sidewall suction theory and sidewall interference correction method to remove effects of sidewall on model. the results of oil - flow test show that selection rational suction wary can obtain better testing results. by investigations on effects of the sidewall boundary layer suction and application of a sidewall interference correction method

    為了很好地解決多機場航班隊列的擁塞問題，在將進場容量、離場容量與機場容量作為統一整體的情況下，充分考慮了機場間的網路效應，詳細研究了多機場航班隊列的優化問題，建立了多機場開放式非實時流量管理的數學模型，通過選取適當的決策變量，使其為線性0 - 1整數規劃模型，實現了中心流量集中管理.與其它演算法不同，本文提出的啟發式隱枚舉演算法能很好地解決此類問題，對某機場網路系統的模擬結果證明了所建模型、優化演算法及相應軟體的有效性和可靠性
