摘要介紹了石煤提釩傳統工藝的改進以及酸法萃取、無鹽焙燒酸浸萃取、氧化焙燒堿浸等幾種從石煤無污染提取五氧化二釩的工藝流程，上述工藝不但生產過程無環境污染，釩的回收率還大有提高，是很有前途的清潔生產工藝。Effects of diverse environmental factors on the growth rate ( od4oo ) and nitrogenase activity ( ara ) of the strain w12 hi nitrogen - free culture were investigated in our experiments. the results implied that the strain w12 could easily adapt to different cultural conditions : it could use various carbon sources ( especially glucose, sucrose, malic acid, mannitol ), propagate quickly and fix nitrogen at a temperature range of 15 ? to 40 ? and at 25 - 35 ? for optimum, at a ph range of 4 to 8. 5, at a saline concentration range of 0. 01 % to 1. 5 % ; low nlv " concentration had little effect on its nitrogenase activity. ara could also be detected when it grow in the culture media with 5mmol / l ntv "
W12菌株對環境因子的適應性研究：無氮培養條件下，測定溫度、碳源、酸堿度、滲透壓對w12生長及固氮能力的影響，結果表明，在15 - 40下均能生長並表達固氮酶活性，其最適生長及固氮的溫度為25 - 35 ；能利用葡萄糖、蔗糖、蘋果酸、甘露醇等多種碳源生長並固氮，當培養基中同時存在蔗糖和蘋果酸時，細菌生長和固氮活性最強；在偏酸和偏堿的條件下（ ph4 . 5 - 8 . 5 ）均能保持較強的生長勢和較高的固氮酶活性，並能通過調節自身代謝平衡並適應環境的酸、堿性變化，使培養液趨于中性：能耐受較高的滲透壓，培養液中卜、 5 naci濃度對其生長和固氮酶活性影響不大，當naci濃度升至2時，菌株的生長勢及固氮酶活性才有所下降：低濃度的鉸對其固氮酶活性影響不大，在01enviromental protection neutral oil cleaning technology : european general - purpose neutral oil treatment technology is used for cleaning before spray coating instead of using acid o alkali agents. this pollution - free cleaning technology ensures that no acid or alkali substances are left on plate surtace after cleaning, and further guarantees the quality of later spray coating for stronger powder adhesion without blistering or coming off
1環保中性塗油清洗技術：在噴塗前的清洗技術，採用歐洲通用的中性塗油處理技術杜絕使用酸堿類試劑，對環境無污染，並保證清洗后的板面無酸堿殘留，保證后續噴塗質量，使粉末附著力更強，不易起泡不易脫落。Due to their high oxidation, multiple electron transfer, and high intrinsic energy, we refer to the cells containing fe ( vi ) compounds as " super - iron " batteries with more energy capacity compared to conventional alkaline batteries. the three charge reduction of fe ( vi ) represents a high energy and capacity source of cathodes, and the products ( ferric oxide ) have been considered as an environmentally benign substance
如果fe （ ）化合物作為電池的陰極材料時，其氧化反應為3電子過程，且反應產物為fe _ 2o _ 3 （鐵銹） ，與一般傳統堿性電池相比，它是一種高能，而且放電產物對環境無污染的綠色電池，目前，它的研究已成為電池研究領域的一個熱點。Particular wires, can be used for long time under the condition of - 65 200 anti strong acid and alkali, durable usage range : be used with intercoms and access control systems. can be installed onto wooden door, metal door, glass door, fireproof door function : working voltage : 12vdc working current : 0. 53a working condition : 40 50 holding force : 280kgs working mode : cut off power to open when the door is being locked, the led turn green, and when the door is open, the led turn red. with network signal output insulated test : dc500v absolutely insulated in 1 minute dimension of the magnet board : 80x24x3mm dimension : 230x40x25mm weight : 1780g
