沉降硫 的英文怎麼說
中文拼音 [chénjiàngliú]
沉降硫
英文
precipitated sulfur-
According to the thermodynamics analysis of spontaneous mineral of iron, we assumed : when sewage disposal, if sulphur is eliminated prior, this makes the consistency of iron ' s ion keep high relatively, it will react with phosphorus, produce heterosite, vivianite precipitate. this will decrease the interior load of the phosphorus in sediment, and reduce the consistency of the phosphorus in the dianchi lake

礦床地質特徵以及常微量元素、稀土元素、同位素、成礦流體等地球化學特徵的研究表明,礦床成礦物質是多來源的,天寶山礦床成礦物質主要來自上部地殼和造山帶各種沉積巖,大樑子礦床成礦物質主要來自震旦系燈影組地層;兩個礦床成礦溶液主要來自大氣降水;硫大部分來源於同時期的海相沉積地層(震旦系燈影組)中被細菌還原的海水硫酸鹽。Study on s input via atmospheric dry deposition into agroecosystem
大氣干沉降向農田生態系統輸入硫素通量研究The experimental results of the flow characteristics of the mmc heat sink indicate that the critical reynolds number signifying the transition from laminar flow to turbulent flow is in advance ; under the same experimental conditions, the variation in entrance direction of the microchannel inlet and outlet has little effect on the microchannel ; the experimental values of the friction factor of the de - ionized water in a microchannel agree well with those calculated using the theoretical laminar formula ; furthermore, a comparison of the experimental results and simulation results shows that navier - stokes equation and rng - turbulence model can be used to model the laminar and turbulence flow regions in a microchannel ; meanwhile, the correlations of the flow resistance in the turbulent flow regions for the de - ionized water as the working fluids are obtained from experiments
對歧管式單通道熱沉流動特性的研究結果表明,微通道內流體流態由層流向紊流轉變的臨界雷諾數提前;改變流體的進出口方向對熱沉總壓降造成的影響很小;摩擦系數的實驗值與理論值較接近;數值模擬結果能夠與實驗值較好吻合;並由實驗給出了紊流區流動阻力的實驗關聯式。此外,選用十二烷基硫酸鈉( sodiumdodecylsulphate , sds )以及烷基多糖苷( alkylpolyglycoside , apg )作為減阻添加劑,研究了表面活性劑添加對微通道流動特性的影響。The effect of the electric field on the morphology of cds prepared by the route of chemical deposition
電場對化學沉降制備的硫化鎘納米顆粒的影響Gas - solid two - phase flow is existed widely in multiphase flow system, for example, desert sand in nature, fuel transportation in field of chemical industry, metallurgy, energy sources and foodstuff, and so on, as well as pneumatic conveying and dust treatment of materiel in bulk ( i. e. sands, corn and plastic granula etc. ). in addition, sulfureted bed, whirlwind dust - exhaustion, sedimentation room and filtration process are involved with gas - solid two - phase flow
氣固兩相流在多相流體系中普遍存在,例如,自然界的大漠揚沙,化工、冶金、能源和糧食等領域的燃料配送,散裝物料(如沙子、穀物、塑料粒)的氣力輸送和粉塵處理等,硫化床、旋風除塵、沉降室及過濾過程中也會涉及到氣固兩相流。Estimation of atmospheric sulfur and nitrogen deposition over east china using sub - grid simulation scheme
利用次網格技術模擬華東地區大氣硫氮沉降The epd s long - term monitoring data indicates that the electrochemical potential of the sediment at sam ka tsuen typhoon shelter which reflects its oxygen content was substantially raised became less negative as a result of the bio - remediation programme, and the total sulphide level hydrogen sulphide gas, the source of the bad odour was significantly reduced
環保署的長期監測數據顯示,三家村避風塘的沉積物經生化處理后,其電化學勢反映水含氧量大幅提高負數值降低,而總硫化物水平導致臭味的硫化氫氣體來源則明顯下降。Dispersed elements like cd, ge, and ga were transported in the form of chlorine complexes or adsorbed by chlorine complexes of pb and zn. thermal degradation of organic materials resulted in the generation of ch4 which further initiated the reduction of sulfates and the precipitation of sulfides
Cd 、 ge 、 ga等分散元素可能形成了部分氯化物絡合物或者被pb 、 zn的絡合物吸附而隨之一起遷移;含礦熱液帶來的熱能使礦化圍巖中有機質發生熱降解作用產生甲烷,從而導致硫酸鹽的還原和金屬硫化物的沉澱。分享友人
