Carbamide reacting with H2SO4 forms aminosulfonic acid. Allantoin is prepared by oxidation of the aqueous solution of glyoxal into glyoxylic acid which is then used to synthesize allantoin.

氨基磺酸的合成是用尿素和发烟硫酸反应；尿囊素的合成是用硝酸氧化乙二醛溶液制得乙醛酸后，再加入氢氧化钙和氯化钙，使乙醛酸以钙盐形式析出，然后在盐酸介质中与尿素缩合而成。

On the other hand, the use of isobutyraldehyde would cause the decomposition of porphyrin complex.

另外，若此反应再加入异丁醛与之共催化，则会造成催化剂降解。

The formulation development is based on preformulation results. Prefomulation studies including spectral analysis, solubility, stability and excipient compatibility were conducted.

本实验经由处方前研究，包含T1-11的光谱分析、溶解度、安定性试验、以及与赋形剂相容性，从中挑选合适的赋形剂，再加入不同比例赋形剂，使用直接打锭法制成锭剂并做处方测试。

After the accesssion to wto, our Financial market have to open to world Gradually so the Opposite and mature of mixed managing mode in Western country is must to be a Huge threat to our Financial market ,the Financial department's mixed managing mode has become a Inevitable Trend in our country , author intent to Analyze the research the Present condition of the Financial industry and the reportion of the International situation to Certificate the Necessity of the mixed managing mode and suggest the Measures to it's problem .

在国际经济一体化和金融国际化的浪潮下，我国分业模式下的金融体制日益暴露了整体竞争力不足的缺陷，再加入WTO以后我国金融行业逐步对外开放的背景下，西方国家相对成熟的混业经营模式必然对我国金融市场形成巨大的威胁，我国金融业的混业经营已成为不可扭转的历史趋势，本文旨在通过对我国金融市场现状的分析研究以及对国际金融形势的总结报告论证混业的必要性并对其可能带来的问题及解决措施提出一己之见，希望能够对&混业经营&有所帮助

Silicofluoride acid radical of the mother liquor will be transformed into sodium silicofluoride if excess sodium chloride was added,and the mother liquor was refined.The refined hydrofluoric acid and various aluminum can compose the by-product-cryolite,which can improve the collection rate of fluorin,aluminum and silicon.

其关键技术为氯化钠脱硅：投入过量氯化钠，使母液中氟硅酸根转化成副产品氟硅酸钠，母液被精制；再加入精制氢氟酸与各形态铝合成冰晶石副产品，从而有效地提高了氟、铝和硅的收率。

CNTs were first pre-treated using acid solution (HNO3) to obtain CNTs functionalized with carboxylic groups. Subsequently, the stearyl alcohol was grafted onto CNT with the assistance of dehydrating agent, N,N'-dicyclohexyl-carbodiimide. Excellent dispersion in organic solvents such as acetone, THF, and chloroform was found for the modified CNTs (CNT-C18). In addition, the PBS/CNTs nanocomposites were then prepared through simple melt-blending. Mechanical properties, thermal behavior, conductivity of resultant polymer/CNT composites were investigated. The results show that excellent dispersion of nanotubes in the PBS matrices was achieved.

为了增加多壁奈米碳管在复合材料中的分散性，将碳管表面进行化学修饰，首先将多壁奈米碳管浸入HNO3溶液中，进行酸化，使碳管表面带有羧酸的官能基，然后再加入十八烷醇，在温和的条件下，藉由N，N'-二环己基碳二亚胺(N，N'-dicyclohexyl- carbodiimide，DCC)脱水剂脱水，使碳管和十八烷醇之间产生酯基的化学键结，改质后的碳管可以分散在acetone、THF、chloroform…等有机溶剂中，结果显示成功的利用DCC脱水剂完成碳管的改质。
