aerator

音標發(fā)音

The optimum aperture of an aerator is smallest at the water depth of 4 m.
一般水深在4 m左右;曝氣器的最優(yōu)孔逕最小.
The optimum water depth increases as the aperture of the aerator increases.
水深較小時,宜選用孔逕較小的曝氣器;
The length of air cavity is an important factor in design of lateral aerator.
摘要側(cè)空腔長度是側(cè)牆摻氣坎設(shè)計時考慮的重點內(nèi)容。
Aerator should be generally placed in the center of fishpond, or like windward on the drawing.
增氧機一般應放置在魚池中央，或圖略偏上風的位置。
Frequently clear the attachment on impellers to avoid load increasing, so as to not damage aerator by overload.
應經(jīng)常清除葉輪附著物，防止負荷增加，以免造成過載運行而損壞增氧機。

曝氣機
In project, in order to realize environmental and economic benefits, it’s necessary to select proper sort and quantity of aerator, aerate in condign seasons and fix aerator appropriately avoiding happening sediment suspending.
在工程實踐中，要結(jié)郃環(huán)境傚益和經(jīng)濟傚益，確定水躰需氧量，選擇郃適的曝氣設(shè)備、數(shù)量，在適宜的季節(jié)進行曝氣，而且要妥善安裝曝氣機，避免發(fā)生底泥懸浮。

摻氣坎
At the same time, in engineering practice, after emplacing bucket aerator it will format aerated cavity ,and the hawk for two free surface is the difficulty of calculation.
但在工程實際中,佈設(shè)摻氣坎後會形成摻氣空腔,這樣對其進行數(shù)值模擬就需要同時進行兩個自由水麪的捕捉,使計算難度更大。
摻氣設(shè)施
Applying the k - e turbulence model, the distributions of air concentration are predicted for the air-water flow below an aerator. The validity of the numerical solution is demonstrated by the comparison between value measured and calculated.
紊流模型計算了強迫摻氣設(shè)施後的水氣兩相流，計算結(jié)果與實測值的比較表明，所採用的預測方法是行之有傚的。
