浮懸塵埃 的英文怎麼說
中文拼音 [fúxuánchénāi]
浮懸塵埃
英文
suspended dust-
The dust charging associated with the electron beams including the secondary emission of dust can dominate the dust surface potential in the close cathode region. in this case, dust of the same size can levitate at two different positions in the cathode
另外還發現：在考慮極板有強電子束發射和塵埃粒子本身的二次電子發射時，同一大小的塵埃粒子能夠懸浮在鞘層中兩個不同的位置。Most of the ac systems in the fehd public markets are equipped with disinfection units and filters to disinfect and remove particulate matters, dust and odour from the recirculated air
（二）食環署轄下公眾街市的空調系統大都設有空氣凈化系統和過濾器，為循環的空氣消毒、清除懸浮粒子、塵埃和臭味。( iii ) dust charging and levitation in cathode sheath of glow discharges with energetic electron beam. the dust charging and levitation in a collisionless cathode sheath of dc glow discharges with energetic electron beams released from a plane cathode are investigated with a self - consistent theoretic model
（ ）塵埃粒子在極板有高能電子束發射輝光放電鞘層中的充電與懸浮採用自洽的鞘層模型和塵埃粒子充電模型，我們研究了在極板有高能電子束發射輝光放電鞘層中塵埃粒子的充電與懸浮。They are equipped with continuous monitoring instruments for measuring sulphurdioxide, nitrogen oxides, photochemical oxidants and carbon monoxide. respirable and total suspended particulates ( dust ) and lead concentrations are also measured
站內的監察儀器，不斷測量本港空氣中二氧化硫、氧化氮、光化學氧化劑及一氧化碳含量，同時也測量可吸入懸浮粒子、總懸浮粒子（塵埃）和鉛的含量。The human source includes emissions from motor vehicles and industrial processes, e. g., power stations, fugitive dust from cement works, construction and demolition activities. the natural source includes soil, salt and pollens
空氣中總懸浮粒子有兩大來源，人為的來源包括車輛廢氣發電廠排出的廢氣以及在製造水泥或建築工程中產生的塵埃，而天然的來源包括泥土鹽及花粉等等。Standard practice for continuous sizing and counting of airborne particles in dust - controlled areas and clean rooms using instruments capable of detecting single sub - micrometre and larger particles
使用能檢測單個亞測微計及較大粒子的儀器在控制塵埃區域及無菌區中連續測定空氣中懸浮粒子的大小及計數In the same way, under stable and dry conditions, dust particles suspended in the air are not easily dispersed, resulting in haze
同樣，在大氣穩定而又乾燥的情況下，近地面的懸浮塵埃微粒不容易擴散，形成煙霞。分享友人
