air bump 中文意思是什麼
air bump
解釋
空氣突出-
One side, groovy cast steel flap valves increase the head loss, waste electricity, the other side, when flap valves close, it always delay time because of it ' s low proportion. the bump load seriously threaten the safety of pumping station. through the research and development of flap valve used in the renovation practices in the design of air - filled floating flap valve in no. 1 chuhe pumping station of anhui province, the working characteristics and design methods of air - filled floating flap valve are studied in this paper
但在拍門運行使用的同時，又時常暴露出一些缺陷，主要有：一是常規的鑄鐵或鑄鋼拍門加大了流道的水頭損失，特別是對于裝機容量較大的排澇泵站，其電能損耗相當可觀；二是拍門在自重下下落關閉時，往往由於過多考慮水頭損失導致浮重過小而延誤閉門時間，致使水體倒灌，再因緩沖裝置失靈導致閉門時門體對門框撞擊力很大，嚴重危及站身安全。 -
Planar laser induced fluorescence ( plif ) and multi - dimensional cfd software was used to study the fuel - air mixing process in traditional combustion chamber and bump combustion chamber, the experimental and simulated result agree well in room condition. the fuel - air mixing process in high pressure and temperature in traditional and bump combustion chamber were compared. the result show that fuel and air can mix more quickly in bump combustion chamber than in traditional combustion chamber, fuel - air mixture in bump combustion chamber is more homogenous than in traditional chamber
進一步對高溫高壓下傳統燃燒室和bump燃燒室內燃油空氣混合好壞進行了對比研究，提出了衡量燃油與空氣混合好壞的三個指標，發現bump燃燒室內燃油能在更大的體積內與空氣混合， bump燃燒室內燃油比傳統燃燒室內燃油分佈相對更均勻， bump燃燒室內燃油濃度耗散率為傳統燃燒室內燃油耗散率2 . 8倍，能更快與空氣混合。 -
The last or main injection pulse is set around tdc. when the diesel spray impinging on the combustion wall, the bump around the combustion chamber wall can strip off the wall jet and form a secondary spray in combustion chamber, so the fuel and air can mix well and homogenous
在主噴射時刻，利用燃燒室壁面的bump迅速剝離壁面射流，在空間形成二次射流，二次射流進入燃燒室空間后，再一次與空氣混合，形成相對均勻的稀混合氣。 -
Moreover, the secondary wall - impingement distance should be properly reduced in order that the bump play a part in the formation of lean mixture with the increase of environmental pressure or density owing to both the increase of air entrainment, momentum losses and the decrease of the spray tip velocity and penetration
而且當壓力或密度較高時，由於噴霧的空氣卷吸量及動量損失增大，貫穿速度降低及貫穿距減小，為使bump發揮作用，應適當減小二次撞壁距離。 -
There is fibroma of a nerve on my foot, be as a child with respect to some, accompany me to be brought up together now, it has a volume with black soya bean only, air became cold every that day, or slow - witted in air conditioning room long, the metropolis is faint do painful, bump into it not carefully to be able to let me think tear usually
我的腳上有一個神經纖維瘤，是從小就有的，伴隨我一起長大到現在，它只有一顆和黑豆一樣的大小，每當天氣變冷，或在空調房裡呆久了，都會隱隱做痛，平常不小心撞到它都會讓我想掉眼淚。
