本文所做的主要工作包括以下几个内容：一、选取了常见的热膨胀系数大的材料制作封装元件，经过多次一80℃到80℃反复测试，封装元件没有出现老化开裂、封装裂纹、空洞、离层等缺陷，封装材料具有良好的温敏稳定性及复用性，与光纤相容性较好；二、对光纤光栅进行简单、实用的封装处理，就封装效果的优劣性、波长测量的准确度、重复性和封装时产生的波长损失等方面进行了一系列的实验，得出了初步的结论；三、对温敏和温度补偿式封装的实验数据进行了详细的分析和对比，从数字上对温变过程中光纤光栅中心波长的改变及温变曲线进行了定量的分析，在大量实验数据分析结果的基础上，总结出哪种材料封装效果更好，以及如何有效的减小实验误差。

The last but not least, it is also owning to the rapid development in computer science and information technology. Such as, some computational task, which previously must be executed by using super-computer, now can be carried out by personal computer, and at the same time, the network speed and band width of data bus and input/output equipment have increased several times. In addition, the improvement of the high quality graphic displaying is available. All these provide strong support for cryoEM high-resolution reconstruction study.

目前，在低电子剂量的情况下，冷冻电镜照片可以记录到3-4 〓的信息，使用冷冻电子显微镜进行高分辨三维重构工作，已经获得6.5-8〓高分辨率水平的结果，可以分辨出蛋白质的α螺旋、识别出蛋白质的β折叠等蛋白质二级结构；其次是，三维重构算法效能的不断提高，使得对二十面体取向和中心参数计算的可靠性大大提高；再次是，由于计算机和信息技术迅猛发展，例如，以往需要使用大型计算机的计算任务已经可以被一般的个人电脑完成，网络速度、数据总线和硬盘等I／O设备的带宽成倍增长，以及图像显示能力的提高都为冷冻电子显微镜高分辨三维重构技术提供了强有力的支持。

Now the core conflict is once again becoming entangled in a bigger one—perhaps even more dangerous this time because Iran is more eager than were the secular Arab states of the 1950s and 1960s to put Islam at the centre of the anti-Zionist cause.

目前，冲突的核心再次同更大的利益冲突相纠缠，而这一次也许更为危险，因为较之二十世纪五十年代到六十年代的非宗教的阿拉伯国家，伊朗更渴望将伊斯兰教置于反犹他复国运动的中心。

This Sm-catalyzed reaction firstly efficiently realized the catalytic cycle in the tandem rearrangement/reduction reaction of α-hydroxy epoxides, and moreover the diastereoselective amplification could be distinctly observed when two C1 epimers in substrate were subjected to this catalytic tandem reaction.

该催化的多功能串联反应，高度非对映选择性地一步控制了含有季碳的三个相邻立体中心，有效地构建了&2-季碳1，3-二醇&结构单元，首次实现了此类重排—还原过程的催化循环，其中对于两个C1位的差向异构体底物，此反应具有明显的非对映选择性放大特点。

The stretching influence on the near trusses should be considered when using the stretching-twice method, and the construction is hard to be controlled. The Harbin exhibition sports center with a 128m support span, attached to a deep design calculation of the super-large span prestress truss string structure, stretching once in tension bed method is brought forward for the bottom cable of the single truss string structure. From calculation research on the friction force between the tension bed and the truss string structure, the friction influence is considered for the displacement method of the middle of span, with the action of the fixed cable stress. This method, with vertical displacement of the middle of span as its main control target for prestress stretching, is successfully applied in the prestress stretching construction of the project.

二次张拉需考虑张拉对相邻桁架的影响，施工控制难度大，本文结合哈尔滨会展体育中心支座跨度128m的超大跨度预应力张弦桁架结构的深化设计计算，提出了单榀张弦桁架下弦拉索胎架一次张拉法施工方法，通过对张拉阶段胎架与张弦桁架间摩擦力的计算研究，定量索力下跨中位移法考虑摩擦力影响，以跨中竖向位移作为预应力张拉的主要控制指标，成功地完成了该工程预应力张拉施工。

The positive peptide cleavage promoted by complex, CuⅡL and the negative response of CuⅡ/dien complex suggest the merely hydroxy pendant in complex have no ability to attack the peptide bond. The synergic carbonyl activation by metal coordination is essential for the cleavage of peptide bond promoted by CuⅡL.

比较相应铜配合物及二乙烯三胺铜配合物的切割性能，提示羟乙基侧臂单独难以实现相邻肽键的切割，高配位数金属中心对肽键羰基的活化与羟基的协同进攻是该类配合物切割多肽的可能机制。

徐小瑜Concord的董事长对记者说，过去的贸易中心之一，集体会员制度现在已经转化为股份制公司，重组后的公司登记册中的份额更雄厚的实力，资金500.0万元从原来的增加二千点零零零万元。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
