The system is composed of polysilicic ions and polyaluminous ion s with the participation of polyaluminous ion s, the Si-O specific line which is inherent in the examination of infrared spectrum is gradually reducing and becoming a broad belt, the non-ion bond reactions between polysilicic ion and polyaluminous ion is proved by observasion with electron microscopy.

稳定胶体态的硫硅聚铝和氯硅聚铝是性能优良的絮凝剂，体系中含有聚硅离子和聚铝离子。红外光谱测试固有的Si—O特征峰随聚铝离子的引入逐渐衰减，变成较宽的带，聚硅离子与聚铝离子间存在着一种非离子性的健合作用，电镜摄像观察证实了这一结论

Ettringite is not stable in concrete, however,it always tends to recrystallize.

文章摘要：钙矾石是水泥重要的水化产物之一，也是铝酸盐类膨胀剂产生膨胀的主要物质，但它在混凝土中并不稳定，容易发生重结晶。

METHODS: For 35 eyes of 31 cases of complicated cataract in uveitis with small pupil, the posterior synechia was separated with the help of viscoelastics or papillary collar resection of iris.

对葡萄膜炎并发性白内障小瞳孔患者31例35眼，在葡萄膜炎控制稳定，炎症消退3mo后，借助粘弹剂分离虹膜后粘连或施行虹膜环形切除，再行白内障超声乳化或囊外摘出及人工晶状体植入。

The experimental results shows, if the ratio between MS-1 and OP-10 rangs from 1:1 to 3:l,and the total dosage of them is about 20% of Octamethylcyclotetrasiloxane (D4 ) in quality, we can obtain a kind of stable seeded emulsion of organic silicone modified acrylic ester emulsion. At the same time, if the ratio between MS-1 and Tetramethylammonium Chlorideis l:1.7,the total dosage is about 50% of D4 in quality; the ratio between MS-1 and Cetyltrimethylammonium Chlorineis 7:1, the total dosage is about 25% of D4 in quality,we can also obtain stable seeded emulsions. But if the complex emulsifier system is made of TMAC and OP-10, MS-1 and Peregal O or CTAC and Span-80, we can not synthesize any kind of satisfactory seeded emulsions.

实验结果表明：当MS-1与OP-10的质量比为1：1～3：1，总用量为八甲基环四硅氧烷(D_4)的20％左右时，可合成稳定性良好的硅丙种子乳液；MS-1与四甲基氯化铵的质量比为1：1.7，总用量为D_4的50％左右，MS-1与十六烷基三甲基氯化铵的质量比为7：1，总用量为D_4的25％左右时，亦能得到稳定的硅丙种子乳液；而TMAC与OP-10、MS-1与Peregal O以及CTAC与Span-80的复合体系作为乳化剂时均不能得到满意的硅丙种子乳液。

Some additives that could enhance the enzyme stability were screened through single factor experiments, such as 5 mmolL^(-1) Ca(superscript 2+), 20 mgmL^(-1) trimethylene glycol-single methyl ether, 0.01% 4-formyl phenyl-boron dihydroxide, 1% glycerine.

EDTA was used as masking agent, and trisodium citrate as total ion strength adjustment buffer was added to stabilize the ionic activity coefficient. The pH was controlled at about 5, the results were directly obtained by Gran graphing method.

以EDTA做掩蔽剂，加入柠檬酸三钠为总离子强度调节剂，使离子活度系数相对稳定，pH值控制在5左右，用Gran氏作图法直接查得结果。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
