逆溫現象 的英文怎麼說
中文拼音 [nìwēnxiànxiàng]
逆溫現象
英文
temperature inversion-
A temperature inversion is a meteorological phenomenon where air temperature increases with height
逆溫是一種氣溫隨高度而增加的一種氣象現象。When a temperature inversion is formed in the pearl river delta ( prd ) region, or when a weak northerly or northwesterly wind prevails, ambient air pollutants ( including nox and voc ) in the region will be trapped easily in the lower atmosphere and cannot be dispersed effectively. the above factors, if coupled with strong sunlight, will favour the building up of ozone concentrations
當珠江三角洲區域一帶出現逆溫層現象,或者吹微弱北或西北風時,區域內空氣中的污染物(包括氮氧化物及揮發性有機化合物)很容易會被困在大氣的低層,不能有效消散;如再加上強烈的陽光,臭氧濃度便會增高。For instance, hot weather and rising air can help dispersion of air pollutants ; rainfall can wash out certain pollutants in the air ; an occasional phenomenon known as temperature inversion can trap air pollutants in the lower atmosphere ; and still wind conditions can inhibit effective dispersion of air pollutants. moreover, when a weak northerly wind prevails in southern china, the impact of regional air pollution on hong kong will become more serious
例如,炎熱天氣和上升的空氣有助空氣污染物消散;降雨可沖走空氣中部份的污染物;偶爾出現的逆溫層現象能把空氣污染物困在大氣的低層;風靜的情況可引致空氣污染物不能有效消散;及當華南地區吹微弱北風時,整個香港受區域性空氣污染問題影響也會特別嚴重。All of the results indicated the turbulent boundary layer had been turned into the laminar layer. the skin friction coefficient drops rapidly. this result not only proved the phenomenon of reverse transition had occurred, but also showed that this condition was drag - reducing condition
實驗結果表明板面附近的流動已由湍流流動轉變為層流流動,同時平板表面的摩擦系數較沒有溫度梯度時有大幅度下降,不僅證明了邊界層逆轉捩現象的存在,也說明了這種條件起到了減阻的效果。Phenomenon of reverse transition on a heated flat plane with stable temperature stratification
加熱平板表面溫度分層產生的湍流逆轉捩現象As the temperature of pyrolysis and the soak time increasing, the carbon materials become more stacked, the specific surface area reduces, both reversible capacity and irreversible capacity decrease, the initial coulumbic efficiency increases, and the hysteresis in the voltage profile between charge and discharge is cut down
隨著熱處理溫度的升高和恆溫時間的延長,所得炭材料的有序化程度增加,比表面積減小,可逆嵌鋰容量與不可逆容量均減小,首次充放電效率增大,電壓滯后現象得到抑制。When a temperature inversion is formed in the pearl river delta ( prd ) region, or when a weak northerly or northwesterly wind prevails, ambient air pollutants ( including nitrogen oxides ( nox ) and volatile organic compounds ( voc ) ) in the region will be trapped easily in the lower atmosphere and cannot be dispersed effectively. the above factors, if coupled with strong sunlight, will generate ozone under photochemical reaction between nox and voc and lead to the phenomenon of photochemical smog
當珠江三角洲區域一帶出現逆溫層,或者吹微弱北或西北風時,區域內空氣中的污染物(包括氮氧化物及揮發性有機化合物)很容易會被困在大氣的低層,不能有效消散;如再加上強烈的陽光,氮氧化物與揮發性有機化合物便會產生光合化學反應,形成臭氧及引致光合化學煙霧現象。分享友人
