选择蒙脱石，高岭石，伊利石等三种在储层中最常见的储层粘土矿物，两两分别按2：0，1：1，0：2质量配比组成复配物系列；在30℃、50℃温度下按1：5，1：8，1：10固/液比分别与1.6%的Na2CO3溶液反应8h、120h、360h；监测反应前后碱液浓度的变化；计算了各条件下各自的绝对碱耗量。

So it is necessary toobtain the excited states data of alkali molecules such as collisionaldepopulation ,predissociation and collisional transfer rates .

所以获得激发态碱分子的碰撞去布居、预离解率及碰撞转移的实验数据是研制这种新型激光器的必要条件。

The hydrolysis of chitin under concentrated alkali conditions would produce double anion because of conjugative effect and steric effect (producing primary amine which had positive ion properties and linear chain macromolecular structure and which has good flocculability and clarification performance).

因共轭效应和空间效应，甲壳质在浓碱条件下水解，能形成双负离子，形成具阳离子性质的伯胺和具有直链高分子结构，具有优良的絮凝性能和澄清作用。

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。
