次硫酸鈉 的英文怎麼說
中文拼音 [cìliúsuānnà]
次硫酸鈉
英文
sodium dithionite-
The experimental results showed that in the condition of this experiment four algaecides all had strong removing rate on algae, and their removing rate increased with dose increasing, and decreased with algae density increasing. according to the removing rate on algae and cost value or so, the sequence of four algaecides from good to bad were potassium permanganate, copper sulfate, hydrogen peroxide and sodium hypochlorite. in the condition of this experiment, the suitable dose of potassium permanganate was 0. 8mg / l, the algal removing rate was beyond 90 % and the cost of this algaecide was only 0. 0068 / m3. the efficiency of algae removal by four algaecides for huanghe river water was studied. the results showed that the majority of huanghe river water was bacillaroiphyta, and the dominant genera was melosira, which reached 78 % ~ 94 %
結果表明，在實驗條件下，四種殺藻劑均具有一定的殺藻效果，藻類去除率均隨藥劑投量的增加而提高；原水藻類數量影響殺藻劑殺藻效果，四種殺藻劑的藻類去除率均隨原水藻類數量的增加而降低；通過殺藻效果、經濟性以及安全性等方面的綜合比較，對于以有毒藍藻為優勢藻屬的引灤水，四種殺藻劑的優劣程度從優到劣排序為：高錳酸鉀硫酸銅過氧化氫次氯酸鈉；在實驗條件下，高錳酸鉀適宜投加量為0 . 8mg l ，藻類去除率高於90 ，所需的藥劑費用僅為0 . 0068元m ~ 3 。The result of sds - page certificated the method 6 % octanoic acid combined with ammonium sulfate got the highest purity, the next was alginic acid sodium combined ammonium sulfate
Sds - page和低壓層析的結果證明，用6辛酸?硫酸銨法提取igy的純度最好，其次是海藻酸鈉?硫酸銨法。Except the igy got from by the method 6 % octanoic acid combined with ammonium sulfate, there were over two tape in others sds - page electrophoretogram
獲得igy產量以海藻酸鈉?硫酸銨法最高，可達5 . 69mg ml ，其次是用3辛酸?硫酸銨和聚乙二醇法。The algae removing rate of four algaecides increased with dose increasing, and the sequence of four algaecides " removing rate on algae from high to low were potassium permanganate, sodium hypochlorite or copper sulfate and hydrogen peroxide. the suitable contact time of four algaecides was also given. the paper compared with the rate of algae removal by any one of three algaecides for two source water
結果表明，實驗期間，引黃水中藻類絕大多數為硅藻，優勢藻屬為硅藻門的直鏈藻屬，占藻類總數的78 94 ；四種殺藻劑的藻類去除率隨殺藻劑投加量的增加而提高，實驗條件下，四種殺藻劑的藻類去除率由大到小依次為：高錳酸鉀次氯酸鈉或硫酸銅過氧化氫。Othogonal testing method was employed to screen electroless nickel bath composition producing deposits with phosphorus content of wtl. 5 %. the paper also discussed the effects of ni2 + concentration, h2po2 - concentration, triethanolamine concentration and bath temperature on phosphorus content of electroless nickel deposits respectively
本研究採用正交試驗方法，篩選並確定了鍍層磷含量為1 . 5的最佳低磷化學鍍鎳配方，並研究了硫酸鎳濃度、次磷酸鈉濃度、三乙醇胺濃度和溫度對鍍層磷含量的影響。Chemical industry : sodium carbonate ( the production of hydrochloric acid, hypo - fluoric acid and secondary chemicals ) ; the production of fluoride and chemical fertilizers ; circulation of reaction liquid in gas absorption tower ; grease extraction ( sulfuric acid ) ; reclamation and regeneration system of waste acid ; transportation of strong acids between chemical plants and vehicles

次硫酸氫鈉含量的快速測定Sodium formaldehyde sulphoxylate
甲醛合次硫酸氫鈉With the increasing of knac4h4o6 * 4h2o and naacehso ? ? 2h2o, the speed of plating was increasing when the concentration of them was low
鍍液的ph值與次亞磷酸鈉和硫酸鈷的摩爾比對鍍層成分、及相結構的影響較為顯著。" induction period " was reflected the quality of electroless plating solution, and affected the efficiency of electroless plating, " induction period " was shortened with the increase of the concentration of nah2 ? o2 ? i - ho and coso4. it was shortened by increasing the ph and the loading of powder
硫酸鈷和次亞磷酸鈉濃度的增加，鍍液的ph值升高，裝載量的增大，反應的孕育期變短；鍍速是反應時間與增重綜合作用的結果。If phosphorus was adequacy in composite powder, co - p alloy coating becomes non - crystalline. the quality of composite powder was better, and the stabilization of solution is improved with the increase of the ph from 9. 5 to 11. 0
硫酸鈷濃度18 40g / l ，次亞磷酸鈉濃度20 40g / l ，可以得到鍍覆均勻、分散性好的復合粉末；增加其濃度，復合粉體的鍍覆質量得以提高。分享友人
