In order to overcome these weaknesses, we use quartic B-spline structure the yield curve, which indicates the less node cubic B-spline model is better under the situation that do not use the forward rate curve, if need to make use of forward rate curve to carry on the economy analysis, the suggestion use quartic B-spline method.

为克服这些缺点，我们用四次B-样条构造收益率曲线，实证表明能克服三次B-样条曲线上述缺点。因此，在不使用远期利率曲线情况下较少节点的三次样条模型是较好选择，当需要利用远期利率曲线进行经济分析时，建议使用四次B-样条法。

Second, using DBU as the base for enolization of propargylic esters of unsaturated acids 18e-k, we developed a tandem Ireland-Claisen rearrangement /isomerization reactions. It has been shown that the reaction sequence affords triene molecules 42a-b and 43a-b in moderated to high yields. Interestingly, with allyl hexa-3,5-dienoates 18i-j as the substrate, the rearranged products underwent further aromatization to give uniquely substituted benzyl acids 44a-b.

其次，以含有活泼质子的烯酸炔丙酯18e-k为底物，在DBU为烯醇化碱、TMSCl为硅试剂的条件下，底物18e-h发生了Ireland-Claisen重排/异构化串联反应，得到完全共轭的三烯类化合物42a-b及43a-b；而以己二烯酸炔丙基酯18i-j为底物时，重排/异构化后的产物进一步发生电环化等反应最终得到芳构化产物——取代苯甲酸类化合物44a-b。

When there is plenty of rope available, the following method illustrated in Figure 20-3 is most secure. The best river man goes first belayed by the second best who goes last. When A gets across, he moves upstream and sets up a belay opposite B. and the next wader ties in at B. Then C pendulums across taking about the same path as A.

水性最好的A首先过溪，由水性次佳，同时也是最后一个过溪的B负责确保工作，当A到达对岸之后，走到B的正对岸做好确保，下一个渡溪者C在B点套入胸部绳圈确保，C的渡溪路径与A相同，当C渡溪时B要给出绳子而A要将绳子收紧，如果C失足被冲掉，会被冲到对岸

1 Part B shall represent and warrant that Part B is an expert fully competent in all phase of the work involved in providing the Services and that Part B shall not deny any responsibility or obligation to Part A on the ground that Part A provided recommendations or assistance with regard to any aspect of this Agreement and that the Services performed by its employees will be of the professional standards consistent with generally accepted industry standards for the performance of such Services and that the Services performed under this Agreement will be proceeded with utmost promptness and diligence and executed in a professional and workmanlike manner.

7.1 B方应代表和担保B方是在涉及提供服务工作的所有方面完全胜任的行家，而且B方不应拒绝对A方的任何责任和义务，前提是A方提供关于此协议任何方面的建议或协助，以及由其雇员进行的服务将具有符合有关这些服务效果的一般公认标准的专业标准，而且按此协议进行的服务将以极端的敏捷和勤奋进行和以专业而工作熟练的方式实施。

The results showed that the contents of chlorophyll a and chlorophyll b decreased,and contents of pheophytin a and pheophytin b increased, but chlorophyllide a and chlorophyllide b changed slightly.

After the click reaction of the SCL micelles and azide-terminus PNIPAM homopolymer, the novel PNIPAM-functionalized SCL micelles with pH-responsive cores and outer thermosensitive coronas were prepared, which was investigated act as excellent candidate of nanosized drug delivery vehicles. Finally, two types of novel shell cross-linked micelles in aqueous solution were prepared from these remarkable PMEO_2MA-b-P(DMA-co-QDMA)-b-PDEA triblock copolymers by cross-linking the inner P(DMA-co-QDMA) shell of micelles upon the addition of diazide tetra derivative in the presence of copper catalyst using click chemistry.

另外，还可以使用溴丙炔对ATRP聚合出的PMEO_2MA-b-PDMA-b-PDEA三嵌段的中间PDMA嵌段进行部分季胺化，这样可以利用两端叠氮化的四甘醇来交联由PMEO_2MA-b-PDMA-b-PDEA在不同条件下形成的两种分别以PMEO_2MA或PDEA为核的胶束，从而实现了从同一个聚合物直接在水溶液中得到两种内核不同敏感的壳交联胶束。
