沉澱富集 的英文怎麼說
中文拼音 [chéndiànfùjí]
沉澱富集
英文
concentration by precipitation-
According to the analysis on the lithogeochemical features and the carbon and oxygen isotopes of calcareous sandstones, it is realized that there some genetic relation between the formation of calcareous sandstone and uranium mineralization in the oxidation - deoxidation transitional belt, that is the precipitation and enrichment of uranium is accompanied by the deposition of carbonate and formation of calcareous sandstone
根據鈣質砂巖的巖石地球化學特徵，結合碳、氧同位素分析認為，氧化還原過渡帶中鈣質砂巖的發育與鈾礦化的形成具有一定的成因聯系，即在鈾沉澱富集成礦的同時，伴隨著碳酸鹽的析出作用，形成鈣質砂巖。This process was propitious to enrich, activate, transport the copper. in different alteration granodiorite porphyry, sio2, k2o, cu, mo are depleted in the fresh and weakly altered rock, and are enriched in the strongly altered rock, cl is also enriched in the strongly altered rock. but na2o and fe are extracted from the porphyry into the ore - forming fluid, especially the presence of fe is in favor of cu deposition
在銅廠巖體不同的蝕變帶中， sio _ 2 、 k _ 2o 、 cu 、 mo等從新鮮斑巖甚至弱蝕變帶中帶出，而在強蝕變帶強烈富集， cl同樣有在強蝕變巖石中富集的趨勢；而na _ 2o 、 fe從斑巖體中帶出，進入流體相中，流體中大量fe的存在，有利於銅的沉澱、富集成礦。The study of cadmium concentration mechanisms under supergene weathering action can offer countermeasures in preventing cadmium pollution from the mining of phosphate rock
研究福元素在表生風化作用下的活化遷移沉澱富集機理可以為防治磷礦山開采中可能產生的鎘污染提供對策。All hi all, the coat layer distribute unevenly. with the increase of al2 ( so4 ) 3. 18h20 amount, the flaky coat layer grow up and thicken
並且隨覆層前驅物加入量的增加，沉澱法改性石墨表面局部富集的絮狀覆層物質增多，覆層變厚。Thus precipitations of cadmium outside and inside the cell were considered to be important mechanisms of cadmium resistance and accumulation of f2, and it is possibly related to alkali produced by f2 during growth
所以認為胞內外沉澱物的形成可能在該菌的抗鎘和富集鎘機制中起了重要作用。 f2生長過程中培養基ph值明顯上升，推測沉澱物的形成可能與該菌產生堿性物質有關。Determination of trace nickel and cobalt in potable water by flame absorption spectrometry - preconcentration of coprecipitation
用共沉澱富集分離火焰原子吸收分光光度法Analysis of water used in boiler and cooling system. determination of chloride. coprecipitation concentration and spectrophotomenry
鍋爐用水和冷卻水分析方法氯化物的測定共沉澱富集分光光度法In regard of the deposition coating way, the results of experiments show that ph value have no influence on the coat layer forming. under different ph value in these experiments, graphite surface ca n ' t be coated mostly. just on some surface of graphite, is there the flaky coat layer deposited
沉澱包覆工藝改性研究結果則表明：沉澱法對ph值的選擇性較小，在本試驗選擇的ph值范圍內，石墨表面大部分沒有被包覆，只有小部分表面有局部富集的絮狀覆層物質沉積，包覆均勻性差。分享友人
