pressure and suction effect 中文意思是什麼
pressure and suction effect
解釋
壓吸效應-
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 -
The wind magnitude and wind pressure can be easily adjusted in a wide range with a displaying device avilable. a well - illuminated air suction hood is equipped, which ensures clear observation of the movement of materials. besides, on both sides of the screen there are four holes available that make cleaning easy. the inclination angle of screen can be adjusted within a scope of 7 - 9. therefore, this machine is able to maintain stone - removing effect even the amount of material fluctuates. it can be used to remove the mixed stones in foodstuffs, grains, grease, feedstuffs and chemical products
調節風量風壓方便，且范圍大有顯示裝置，配有大採光吸風罩，物料運動一目了然配有先進照明燈觀察，篩體二側設有四個清理手孔清理方便，去石篩面傾斜角度可可、調范圍7 - 9 ，因此本機在產量波動范圍之內均能達到去石效果及用於去除不同種類，糧食、雜糧、油脂、飼料、化工其它等的並肩石。
