6.has been no repart on the reaction of magnesium with alkali Solve documentS[3-6] said:"Magnesium can not react with alkali. " in this essay, the calculation daal of thermodrnamics and the experimental factS have Proved that magnesium can react with Solid alkali and the chemical reaction on equation is: 2NaOH (s) +Mg(s) = MgO(s) + Na2O(s) + H.
镁同碱反应未见有报道．文献［3～6］认为：“镁不能跟碱反应”．本文的热力学计算数据和实验事实都证明，镁能和固体碱反应，反应的化学方程式是：2NaOH（s）＋Mg（s）＝MgO（s）＋Na2O（s）＋H2（g）↑．
7.Abstract: Controlling AAR with high quality I grade fly ash has been researched.The result shows that the content is more important than the quality for the effect on controlling AAR.The solubility of the fly ash contained alkali is inquired in differ alkali concentration solution.The mechanism of low content accelerating swell and yet high content controlling swell is discussed when controlling AAR with the fly ash contained high alkali content.
文摘:研究优质Ⅰ级粉煤灰对碱骨料反应的抑制效果，结果表明，用粉煤灰抑制碱骨料反应，其掺量因素的影响大于品质因素的影响；探讨了粉煤灰中的碱在不同浓度碱溶液中的溶出情况及用高碱含量粉煤灰抑制碱骨料反应时，低掺量促进膨胀，高掺量抑制膨胀的机理。
8.The effect of the dosages of alkali treatment agent NaOH and promoter1227 on the rate of weight reduction and strength of the fabric during the weight reduction treatment of wool-like polyester fabric with alkali was examined. Alkali weight reduction treatment has improved the gas permeability, hygroscopicity, brilliancy, drape of the fabric and rendered it the style of smooth and crispy handle and full brilliancy of the wool fabric.
探讨了涤纶仿毛织物碱减量处理中碱剂NaOH、促进剂1227用量对减量率、织物强力的影响,碱减量处理改善了涤纶仿毛织物的透气性、吸湿性、光泽、手感、悬垂性,使其具有毛织物的滑、挺、糯风格,色泽丰满
9.The results show that, compared with CWQ coke, the properties of CDQ coke is much better in mean grain size, grain size uniformity, mechanical strength, thermal properties etc. , the ash content, catalytic index (MCI), optical texture index (OTI) etc. are unchanged basically, and its alkali absorptance is strong, alkali resistance is weak, but its thermal properties are still superior to CWQ coke after alkali absorption, its boron absorptance is weak, passivetion effect is bad, thus its thermal propetties is somewhat inferior to CWQ coke after boron absorption.
研究结果表明：与湿法熄焦焦炭相比，干法熄焦焦炭在平均粒度、粒度均匀系数、机械强度、热性能等方面均有明显改善；灰成分催化指数MCI、光学组织指数OTI基本不变；而吸碱能力强，抗碱能力弱，但是吸碱后的热性能仍优于湿法熄焦焦炭；吸硼能力弱、钝化效果差，钝化后干法熄焦焦炭的热性能稍低于湿法熄焦焦炭。
10.5) Corrosion behavior of alloy coating was studied by IM6 electrochemistry workstation. The results showed that oxidation potential(OP) and anticorrosion of Fe-Co-Ni alloy coating in acid, alkali, salt had respective relation as below:alkali>salt>acid and acid
