In my opinion, Cu complexes with unsaturated alcohol to form a complex compound; the nitrogenous compound introduced serves as the complex compound's stabilizing agent and reduces activation energy of reaction; TMPO serves as oxygen carrier and displays it's selective oxidation function. This new method and mechanism also demonstrates significance to other similar organic reactions.3 In the chlorohydrin reaction, NaCIO is replaced by Ca2see Chapter4.4.3.4(2 .A, this method hasn't been reported in previous literature,which exerts more buffer action to the react system, the yield increased from 52% to 88.6%; at the same time it solve the problem of poor stability and low percentage composition of NaCIO.

认为：CuD与烯醇形成络合物：含氮有机物的引入起到稳定络合物，降低活化能的作用：而TMPO则充当携氧子起传递氧的作用，并具有选择氧化功能：这种新的方法和理论对类似的反应(不饱和醇类在络合体系下选择性催化氧化为对应的醛也具有重要的指导作用。3在异戊二烯的氯醇化反应中，用次氯酸钙代替次氯酸钠见第4章4.3.4(2.A，本方法未见文献报道，使反应系统更加温和，收率由52%提高到88.6%：并解决了次氯酸钠稳定性差、有效氯含量低的实际问题，具有重要的实用意义。

In the first place, an American court is often enabled or compelled to adjudicate wholly foreign cases by virtue of a" transient" service of process , or by virtue of an in rem or quasi in rem jurisdiction that is based merely on a fictious situs.

首先，一个美国法院经常能够甚至必须对纯属外国案件作出判决；这种判决是完全依据属地送达法律令状的"过境的"属人管辖权或者是完全依据假定情况的对物或类似对物诉讼管辖权。

This is a public beach, so everyone can come here. Each walked on the beach with bare feet. If there are iron cans or nails on the beach, people may get hurt. Thus, I saw volunteers detecting the beach back and forth with metal detectors and detectaphones and taking away any hurtful ironware. This is American "humanity"-"Love me, love my dog";"do to others what you want to be done to you," which is the spirit to make the US powerful.

由於是公共沙滩，任何人都可以来玩，每个人都是光脚走在沙滩上玩耍，要是有铁罐、钉子，则会伤害到人，因此，我看到有义工用类似军队用的地雷侦测器，头戴侦听耳机在沙滩上来回扫瞄，将会伤人的铁器带走，这是美国的「人道精神」、「爱己及人，爱物及物」，这是美国所以强大的精神支柱。

The thermal stability of diindenyl lanthanidealkoxides is inferior to that of analogous cyclopentadienyl lanthanide complexes.

但是该类配合物的热稳定性相对低于类似的茂基配合物。

In our study,two important lepidopteron pests,beet armyworm and cotton bollworm were surveyed for their endogenous piggyBac.As a result,endogenous piggyBac elements were found in these two insects,and one of the piggyBac elements isolated from the genome of cotton bollworm was intact and thought to be potentially active.1 Clonging and sequence analysis of piggyBac from beet armywormUsing PCR technique,with degenerate primers,a DNA fragment of piggyBac-like element was cloned from the genome of beet armyworm,spodoptera exigua hubner.The DNA fragment was 456bp in length,and the deduced amino acid sequence shares 50%- 78% similarity with other piggyBac elements from insects.But one stop code was found in this DNA fragment.

由于转座子很难用常规的RT-PCR和RACE技术进行克隆鉴定，故本研究在兼并引物PCR的基础上，利用inverse PCR和vectorret PCR技术，不仅调查了鳞翅目两种重要的农业害虫甜菜夜蛾和棉铃虫的內源piggyBac存在情况，同时克隆到了內源性的piggyBac转座子，并且从棉铃虫中获得了一个结构完整、具有潜在活性的piggyBac转座子HaPLE1.1甜菜夜蛾piggyBac转座子基因的克隆与序列分析采用PCR技术，利用兼并引物，从甜菜夜蛾基因组中克隆出一个內源性piggyBac类似因子的DNA片段，并命名为SePLE。

Telocentric lenses work with a wide depth of field. With a telocentric lens, you can image objects of different distances from the lens and the objects stay in focus.

具端着丝粒的镜头(注：我猜是类似于针孔镜头吧)具有宽阔之景深，以具端着丝粒的镜头，你能够将由镜头不同距离之目标物成像和保持目标物在焦。

Moreover, the influence of carbonate on the adsorption process was also studied. Under the anoxic condition, the AVS in Guanting Reservoir sediments controlled the partitioning of most of the metal ions between sediments and pore water.

对于渭河潼关沉积物，由于在组成上和黄土有很大的相似性，本文建立了与黄土类似的表面络合模型，并成功的模拟了潼关沉积物的表面酸碱反应特性及其对铜和镉的吸附特性，同时探讨了碳酸盐在吸附中的影响。

Sand, stone, earth and similar materials: If sand, stone, earth, garden-use turf, moss and other similar material are needed, a layer of leak-proof protective matter must be laid on the floor. The exhibitor must take all preventive measures to keep the above-mentioned materials from sticking to and staining any part of the exhibition hall.

沙石，泥土及类似材料：如果需要使用沙石，泥土，花园用泥炭，苔及其他类似材料，必须在地板上铺贴一层防漏保护物，参展单位必须保证采取了所有的预防措施以免使上述材料粘污展馆的任何部位。

It is not known how rare this resemblance is,or whether it is most often seen in inclusions of silicates such as garnet,whose crystallography is generally somewhat similar to that of diamond;?

现在尚不知这种类似稀少到何种地步，也不知道是否它最常见于象石榴石一类的硅酸盐内含物中，而这类物质的晶体结构普遍地在某种程度上类似于金刚石的晶体结构。

It is not known how rare this resemblance is,or whether it is most often seen in inclusions of silicates such as garnet,whose crystallography is generally somewhat similar to that of diamond; but when present,the resemblance is regarded as compelling evidence that the diamonds and

现在尚不知这种类似稀少到何种地步，也不知道是否它最常见于象石榴石一类的酸盐内含物中，而这类物质的晶体结构普遍地在某种程度上类似于金刚石的晶体结构。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
