衍生

Chapter 1 focuses on the basic introductions about the background, definition, category, characters, economic function, and the specialized aleatory of the credit derivatives.

第一章主要对信用衍生产品产生发展的背景情况、定义、分类、特点、经济作用以及特有的射倖性做了基本介绍，并分析探讨了信用衍生产品与其他具有替代性经济功能的金融产品之间的差异。

The result shows that all two-part allegorical sayings are motivated with three stages of derivation as the common schema.

分析的结果显示，所有的歇后语之语意皆可衍生，且三层的衍生为最普遍的基型。

To avoid the influence of ammonolysis, alcoholysis and hydrolysis on molecular structure identification, in this paper, derivational estimation is utilized to confirm molecular structures ofβ-naphthol-containing sulfonyl chloride intermediates. Then the structures of corresponding sulfonamide dyes are also confirmed by FTIR,~1H NMR and mass spectrometry.

为了避免磺酰氯化合物发生水解、醇解和胺解等衍生化反应影响磺酰氯化合物分子结构表征，本文采用衍生化反推法证明了β-萘酚结构磺酰氯化合物的分子结构，并利用红外光谱、核磁共振氢谱、质谱表征了含β-萘酚结构磺酰胺染料的分子结构。

But in the face of this year the international financial crisis intensified, the market will be targeted at derivatives, and this grave crisis due to excessive derivatives innovation.

但在今年的国际金融危机加剧的压力，市场将针对衍生产品，这严重的危机由于衍生品过度创新。

The bank supports a proposal to send standard derivatives contracts through an industrywide clearinghouse that can be monitored by regulators. J.P. Morgan, however, opposes a requirement that the trades should be moved onto an exchange, in part, because it would inhibit the use of customized derivatives that clients require.

政府提出，针对整个行业设置受监管机构监控的票据交换所，通过这类票据交换所发送标准的衍生产品合约，摩根大通对此表示支持，但反对将衍生品交易转到交易所进行的要求，部分原因在于这种做法将会限制客户要求的定制衍生产品的应用。

Methods: Streptomycin and the derivatization reagent o-phthalaldehyde occur Amine Acetalization generating derivative product with UV absorption and determined the absorbance in special wave length, obtained streptomycin residues in samples then compare with high-performance liquid chromatography.

将试样与衍生化试剂邻苯二甲醛进行胺缩醛反应，即化学衍生处理，生成具有特定波长的紫外吸收的衍生产物，测定其吸光度，求出样品中链霉素残留量，并与高效液相色谱法比较。

The molar ratio of sulfate ions to carboxylate ions is determined by conductometric titration method and the molecular weight is tested by high performance gel permeation chromatography. The precision of these two methods is also studied. To improve the detection sensitivity, guanidine hydrochloride is used as the best derivation reagent of 911. A systematic research is done on the optimum derivatization condition of 911 and Guanidine hydrochloride. The M /G ratio of 911 has direct relation to its biological activity.

论文首先对911的基本理化性质进行了系统的分析，以电导滴定法和高效凝胶渗透色谱法分别测定了分子中硫酸根羧酸根的比值和911的分子量，并探讨了两种分析方法的精密度。911分子没有紫外吸收，为提高检测灵敏度，本文采用荧光标记法，通过对三种荧光试剂与几种寡糖和多糖衍生效果的综合比较，最终确定了盐酸胍为最佳衍生试剂，并以911为代表详细探讨了衍生化反应的最优条件。911糖链结构与褐藻胶主链结构类似，以甘露糖醛酸和古罗糖醛酸的嵌段形式存在，分子中M/G比值与911的物理化学性质和生物活性有直接关系。

A sample-pretreated method of ether-extraction-precolumn-derivation was established, and the chromatographic conditions, which was used for determinating the derivant of extracted UDCA, were decided to be Hypersil C_(18) column(250×4.6mm, 10μm), acetonitrile-methol-0.005mol·L~(-1) phosphoric buffer-triethylamine(50:27:42:0.25, adjusted to pH3.0±0.1 by phosphoric acid) as mobile phase with detective UV wavelength at 247nm and column temperature at 35℃.

建立了乙醚提取-柱前衍生化血浆样品预处理方法，采用Hypersil C_(18)柱(250×4.6mm，10μm)，乙腈-甲醇-0.005mol·L~(-1)NaH_2PO_4缓冲液-三乙胺(50：27：42：0.25，磷酸调节pH3.0±0.1)为流动相的HPLC法，以溴苯乙酮为衍生化试剂，在247nm处测定家兔血浆中熊去氧胆酸衍生化产物。

Firstly synoptically realize the credit derivatives, then analysis the innovation of credit derivatives, and point out the impetus of credit derivatives innovation.

首先对信用衍生产品做了概括了解，然后在金融创新理论框架下分析信用衍生产品创新，并指出信用衍生产品创新的动因。

" The adjective m 33lis} derived from m 3 a only meant "of or concerned with subject matter" in Classical Latin, but its descendant in Late and Medieval Latin and its descendants in Old French and Middle English developed other meanings, such as "consisting of matter.

形容词materalis 是由在古典拉丁语中仅仅意味着&和主题有关的& materia 衍变而来的，但它在中古拉丁语和后期拉丁语中的衍生词和古法语中的衍生词以及中古英语中的衍生词继续发展有了其他的意思，如&由物质组成的&。
