查询词典 alkali

Stone is from rock, and rock is consist of the mineral, the mineral contain iron is the source of the iron in stone products , iron element spread widely in natural world, but most of them appear to be compound, iron element is belong to medium activity metal, under high temperature is easily to be strongly acted with oxygen, sulfur, chlorine, and easily dissolve in abio-weak acid solution and strong hydrochloric acid solution, at the same time, the strong alkali solution also corrade the iron.

石材是岩石经加工后所产生的制品，岩石是由矿物组成的，其中含铁矿物是石材中铁质的来源。铁元素在自然界中分布甚广，但大多以化合物的方式出现，由于铁元素属中等活泼性的金属，在高温下易和氧、硫、氯等元素发生强烈反应，并易溶于无机稀酸和浓盐酸的溶液中，同时浓碱溶液也易侵蚀铁。

There is an old saying in our field --"No dam is not crackable" The crack is mainly because of the bad dilationafter "alkali aggregate reaction", the temperature traverse inside and outsidethe concrete with the happening of heat evolution and the shrink of volume dueto the cooling of concrete.

水电行业有句&无坝不裂&的俗话，产生裂缝的原因主要有&碱集料反应&造成的破坏性膨胀，水泥水化过程中放出的热量出现的混凝土内外温度梯度和水泥石硬化后由于后期降温发生的体积收缩等造成。

UV-B absorbing capacities of methanol and cell-bound alkali extractable phenolics were measured in leaves of potted one-year-old seedlings of Pinus massoniana, Schima superba, Cryptocarya concinna, Castanopsis fissa and Castanopsis chinensis to investigate the UV-B protecting strategy in plants exposed to full sunlight.

通过测定马尾松和荷木，及黄果厚壳桂、藜蒴和锥树叶片中甲醇提取物和细胞壁碱性酚类提取物中UV-B吸收物质的含量，以及叶片叶绿素含量和比叶面积，研究全日光强下植物对UV-B的防护策略。

After SBF solution cultivation for some days, the Ca/P coating was very easily deposited on the porous surface that was constituted of cystiform polygon made up with irregular nanometer circles like honeycomb. The energy spectrum showed that n/n atom ratio is about 1.61:1 which is very similar to that of HA and human bone. The active surface of the porous titanium after acid-alkali treatment and SBF solution condition which calcium-phosphorus ions was supersaturated induced the formation of Ca/P deposition layer.

SBF溶液培养后发现沉积层由蜂巢状多边形胞状物组成，这些胞状物是由网状纳米环无规则排列构成，能谱测定钙、磷元素原子比n／n约为1.61∶1，与HA和人骨中的钙磷原子比很接近；通过对沉积机理的分析，认为微孔钛的活性表面和SBF溶液过饱和离子浓度的环境造成了液相中钙磷盐的沉积。

Key words: Dasyatis akajei cartilage, Muco polysaccharide, Alkali extracting, enzyme issolution

赤魟软骨；粘多糖；碱浸提；酶解

Compared with prozyme A, alkali enzyme was a powerful enzyme for the hydrolysis of corn protein, but it could result deamidation, that was another reason for selecting prozyme A as the first enzyme.

与复合酶A相比，碱性蛋白酶也能较好地作用于黄粉蛋白，但它对酰胺基有较强的水解作用，这是选择复合酶A作为第一次水解用酶的又一个主要原因。

The process and solution of degrease, alkali erosion, brightening pretreatment and pre-electroplating were introduced.

介绍了铝及其合金制件的脱脂、碱蚀、出光及预镀等预处理工艺和配方，探讨了浸锌-镍合金溶液的配制、温度及时间对镀层性能的影响。

The effects of alkali charge,temperature,pressure and time on oxygen delignification were studied.

研究了用碱量、温度、氧压和时间对桉木硫酸盐浆(卡伯值为17.1)氧脱木素的影响。

The chemical activating mechanism of UA is that CG can stimulate pozzolanicity more effective than gypsum because of higher solubility and looser crystal structure; but CG has poor property on retardation setting, and this shortage can be solved by mixing with gypsum; CS can offer alkali activity, which can depolymerize silica and aluminum glass, and benefit for other activity methods and overcome the disadvantage of HF on setting time; Sodium sulfate improves early strength greatly but loses the final strength. NF can improve both early and final strengths.

联合激发技术的化学激发机理是，煅烧石膏溶解度高及晶体结构松弛，比天然石膏的活性激发效率高，但降低石膏的缓凝作用，与天然石膏混合既可提高活性又能保持缓凝作用；干法电石渣提供碱激发，促进高钙灰中硅、铝玻璃体解聚，并克服高钙灰对凝结时间的不利影响；硫酸钠虽然早强作用明显，但使后期强度倒缩，NF使各龄期活性都得到提高；磨细的物理激发使高钙灰大颗粒中的CaO和富集碳组分被磨细、分散，活性增加而危害性降低。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。
