"Half-water-hydrolysis"method is used to modify the preaminolysis of phenylenediamine in"step coupling polymerization". First, dehydrochlorination polycondensation between Si-OH and Si-Cl group during polycondensation reaction is employed instead of dehydration reaction between Si-OH groups before, which avoids the disconnection of Si-N bond destreyed by isolated water and improves the H-bonding template effect of the bridged-phenylenediamine.

探索用&半水水解-脱氯化氢缩聚&法对我组过去提出的&全水水解法&的预胺解法加以改进，经&半水水解&得到的含硅羟基和硅氯基的单体再以脱氯化氢代替脱水的方法减少了极性溶剂存在下游离水断裂梯撑模板的硅-氮键的可能性，有效地提高了对苯二胺梯撑中氢键的模板作用。

The effect of silicon atom in substrate on the reaction rate and the stereoselectivity of enzymatic reactions was revealed by comparison of horse liver alcohol dehydrogenase-catalyzed stereoselective dehydrogenation of the three isomers of acetyltrimethyl propanone and their carbon analogues in aqueous/organic biphasic systems.

本项目通过对比在水－有机溶剂两相系统中，马肝醇脱氢酶催化三甲基硅烷丙酮的三个异构体及其碳类似物的光学选择性脱氢反应，揭示了底物中的硅原子对酶反应速度、立体选择性的影响规律，成功地合成了高对映体纯度的手性有机硅醇，并实现了辅酶的再生。

While the keratinocytes adhered well on the surface of silicone membrane with pseudopodia formation after 1 week under scanning electron microscope, and the cells kept normal morphological and proliferative properties 2 weeks later.

种植于生物硅膜上的表皮细胞，1周时扫描电镜下见表皮细胞在生物硅膜表面贴附较好，有伪足形成，提示细胞生长良好；2周时光镜下见生物硅膜上的表皮细胞形态仍正常，增殖良好。

Use D4 or DMC,vinyl di-blocking agent,ringy vinyl,hexamethyl-disiloxane as raw materials,tetramethyl hydroxyl ammonium as catalyst,we synthesized a vinyl silicone oil.

以D4，乙烯基双封头，乙烯基环体，六甲基二硅氧烷等为原料，四甲基氢氧化铵为催化剂合成了摩尔质量和乙烯基含量不同的乙烯基硅油；以高含氢硅油，含氢双封头，D4合成实验所需的含氢硅油；以白碳黑为填料通过密炼等工序制备了医用高透明液体注射硅橡胶。

And the Si peak value and content of 91SP\'s leaf sheath inside were more than those of Lemont obviously. After being inoculated with R.solani, the sheath blight occurrenced in 91SP and Lemont, but hypha on surface of siliceous cells were few, the hypha number of 91SP\'s leaf sheath inside were obviously less than Lemont, and sclerenchymatous cell\'s wall thickness of Lemont leaf in Si+ rice plants was about 2 times to Si- rice plants.

接种纹枯病菌后，两个水稻品种91SP和Lemont均发病，但两个品种硅化细胞表面菌丝却很少，抗病品种91SP叶鞘内侧菌丝数目明显比感病品种Lemont少，Lemont施硅处理的叶片厚壁细胞的胞壁厚度是缺硅处理的2倍左右。

Silicons are the most in the earth's crust, silicon oxidize the silicon form and exist by two more, is rich in two high-temperature karst which oxidize the silicon, under the function of the pressure, and soak trunks outside gradually inside, there is a crystallization course, it is the silication course.

地壳中硅是最多的，硅多以二氧化硅形式存在，富含二氧化硅的高温岩溶，在压力的作用下，从外及内逐渐浸润树干，并有个结晶过程，便是硅化过程。

The silanol groups of silica, is reacted with various silane reagents to produce covalently bound silyl derivatives covering a varying number of active sites on the surface of the support.

担体的表面，如，硅胶的硅烷醇基团，和不同的甲硅烷试剂反应制备共价键甲硅烷基衍生物，此衍生物在担体表面覆盖了许多不同的活性点。

Results The main reason for the extraction and complications of silicon oil tamponade were similar in both groups.

儿童硅油眼内填充术后硅油的眼内反应与成人基本相同；年龄因素对取出硅油的手术效果无明确影响。

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。

The split between the two groups can hardly be papered over.
