E. the activation of amino acid, the elongation of peptide chain and the termination of the chain reaction, among which the activation of amino acid—the formation of imino acetoxyphosphoranes was the key step.

在这三步中，氨基酸的活化即氨基酸磷烷的形成是整个自组装成肽反应的最重要一步。

Good ordinal nevertheless sense has the content of this 10 paces bit of problem, some does not have correlation between each pace fluctuation for example script language, SQL still has regrettablly is a few links of hair resource is English, meet many people create certain obstacle|||Is these learned that inapproachable god?

这十步的内容不错不过顺序感觉有点问题，每一步上下之间有的没有关联例如脚本语言、SQL还有可惜的是发的一些链接资源都是英文的，会给不少人造成一定的障碍|||这些都学好了那不是无敌神人了么？

Chiral centers of C5 and C8 are directly constructed in the key step of the diastereoselective propargylation from D--tartrate. The methylation and subsequent methoxycarbonylation result in desymmetrization of the terminal dialkynes. The α,β-unsaturated δ-lactone is synthesized after partial hydrogenation and lactonization.

由非天然酒石酸出发，利用双向非对映选择性的炔丙基化反应，在一步反应中同时构建C5和C8手性中心；然后通过末端炔基的甲基化、甲酯基化，延长碳链并对分子去对称化；内酯化得到关键中间体α，β-不饱和六元内酯，再经多步反应转化得到8-epi--Boronolide。

But climbing Pacaya is no easy job: it is 2560 metres high, and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements.

攀登Pacaya的But是没有容易的工作：它是2560米高，并且到达山顶采取二个到三个小时表面上一步向前和二步运动。

The resultsshowed that one electron was photochemically transfered from rich electron part inside the C〓 derivatives to C〓 football. On the other hand,two step PET took place between C〓 and additional electron donor Et〓N, and so C〓anion as well as C〓 dianion could be detected in C〓/ Et〓N system.

结果表明：C〓衍生物分子内的富电子部分与C〓区域间发生分子内光诱导的一步单电子转移过程，对比而言，C〓分子与外加给体Et〓N间可相继发生两步光诱导电子转移反应，依次生成C〓和C〓阴离子自由基。

How to forget a rainy day on the path of mire her's thins smalling figure, one-step 2 moveing the heavy bicycle...

怎么能忘记阴雨天在泥泞的小路上她瘦小的身影，一步两步的挪动着沉重的自行车。。。

But at relatively high temperatures, the alloy exhibits complete superelastic characteristics, and only one-step martensitic transformation is observed.

在较低的形变温度下，沿单晶母相［001］方向的压应力诱发的是两步马氏体相变，材料表现出赝弹性；在较高的形变温度下，只能观察到一步马氏体相变，材料展现出完全超弹性特性。

It is urgent to solve how to produce it efficiently and economically.In this paper, with the guidance of precision forming complex components, basing on the forming theory of obturated-extrusion, combining the technique of hot extrusion, considering the characteristics of steering knuckle, so the one-step precision obturated lateral-bend extrusion forming method and the two-step forming method are presented.

本文以复杂零件的精密成形为指导思想，根据闭塞挤压成形理论，结合热挤压技术，针对轿车转向节零件的自身特点，提出轿车转向节零件的闭塞侧弯挤压精密一步成形法和闭塞侧弯挤压精密预制坯与开式终锻相结合的两步成形法两种工艺。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
