使失去

We are collaborating with researchers in Seattle and at the NIH to try to develop a vaccine for HIV.

Nanomaterials have many new characterizes which different from the normal materials for their small size, big surface area ratio and quanta dimension domino effect, for examples, the metal with good conductor will be turned into nonmetal when the size is reduced tonanometer levels; the resistance of originally nonconductor will be descended greatly when its size is reduced several nanometers or so, and loss the nonconductor property; the general solid is steady under certain conditions, while under nanometer conditions, the capabilities will be effected greatly by the granule sizes, the newness characteristics made nanomaterials have great appliance foreground on catalyze, optics, and industry produce and so on, therefore the nanomaterials have been the hotspot for materials science, chemistry science and so on.

纳米材料由于尺寸小、比表面积大和量子尺寸效应使它具有不同于常规固体材料的新的特征，如原来是良导体的金属，当尺寸减小到纳米量级时就变成非金属型；原来是绝缘体的物质，当尺寸减小到几纳米或几十纳米时电阻大大下降，失去了绝缘体特性；常规固体在一定条件下物理性能是稳定的，在纳米状态下，颗粒尺寸对性能产生强烈的影响等等，这些新奇的特点使得纳米材料在催化、光学、工业生产等各个方面都有着广阔的应用前景，因此，纳米材料目前已经成为材料科学、物理学及化学等学科的前沿热点。1990年7月在美国巴尔基摩召开了国际第一届纳米科学技术会议，正式把纳米材料科学作为材料科学的一个新的分支公布于世。

Because of the nondirectional property of ionic bond and the fully delocalized property of pi electrons on carbon layers, translation will not change the electronic structure of carbon layers, resulting in that A-GIC and AE-GIC hare quite good lubrication as well. The electrons come from metals mainly transfer to the delocalized pi orbitals of carbon layers, and the increase of delocalized electrons will make metal graphite intercalation compound more electro-conductive than graphite itself. Because ionic bond between metals and carbon layers is weaker and its lattice energy is much less than that of typical NaCl crystal, so metals could be left from interlayers. The Mulliken populations of C-C in intercalation compounds are smaller than that of graphite, and the HOMO energy level of GIC is higher than that of graphite too. These Lead to that GIC will easier be oxidized.

由于离子键没有方向性，又由于碳层中的π电子是充分离域的，所以碳层不会由于平移而改变其电子结构，金属石墨层间化合物仍具有很好的润滑性；金属失去的电子主要转移到碳层的离域π轨道中，碳层离域电子增多使金属石墨层间化合物的导电性比石墨增强；金属与碳层间的离子键强度比较弱，其晶格能远小于典型的离子晶体，因而金属易从石墨层中脱出；金属石墨层间化合物中的C-C间Mulliken布居值小于石墨中C-C间的值，且金属石墨层间化合物的HOMO能级也高于石墨的HOMO能级，所以石墨层间化合物中的碳原子较石墨更易被氧化。

What a storm it was! The "Northeaster" they called it, winds of hurricane force creating massive waves, driving the ship before it.

飓风的威力在海中抓起大浪，使他们的船失去控制，船上的人都慌了手脚。

Scientists are searching for ways to destroy nuclear weapons in space to make nuclear weapons powerless and no longer useful.

科学家们正寻找在太空中摧毁核武器的方法，以使其失去战斗力且无法再用。

His purpose was to throw us off guard.

他的目的是想使我们失去警惕。

So pricing of A-share will be different from foreign share's pricing. Policy intervened is an important factor of unusually fluctuates on the stock market of China, and exert a great influence on the skew of the market price. The arrangement of market system and market assured by government make the market up and down caused by policy.

七、政策干预是中国股票市场异常波动的一个重要因素，并对市场定价偏移产生重大影响，我国股市制度安排和政府为股市隐形担保导致政府时刻受制于股市的涨跌，而频繁调控股市又造成股市的政策依赖性较强、市场系统风险加大等不良后果，最终使政策稳定市场能力逐步减弱，甚至失去效用。

There is no such opposite relationship of possessing each other or depriving each other of their independence in the legal sense of husband and wife , and even less the relationship of oppositeness that neither can seize the benefits of the other in the legal sense of property between husband and wife .

比如，男人与女人的关系纯粹只有生命健康需求的互补关系，没有夫和妻在法律意义上互相占有对方使对方失去独立的对立关系，更没有夫妻在财产的法律意义上互相不能侵占对方利益的对立关系。

The lack of land and hunger made the neighboring landlords' opulence and luxury especially intolerable.

饥饿和失去土地的苦痛，使他们更难容忍地主老财的骄奢淫逸。

The thought of grinning politicians telling people how happy they are is truly Orwellian.

露齿微笑的政治家们告诉人们有多幸福的思想事实上是赞成严格统治而使人失去人性的。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
