查询词典 vacancy

It is found that adatom yields, vacancy yields and sputtering yields will all increase along with the energy of incident atoms getting higher. Meanwhile, the quantities as well as distribution of adatom and vacancy play an important role in film growth.

表面吸附原子、空位缺陷以及溅射产额均随入射原子能量的增加而增加；表面吸附原子与空位缺陷的数量与分布，对于薄膜生长模式起着重要作用。

From the results of XPS, ESR and coloration feature, it was inferred that N was embedded into TiO_2 powders to form interstitial and substitutional N doping,and N doped in the part of oxygen vacancy was crucial to emerge visible-light activity. Moreover, N doping played a significant role in restraining reoxidation of oxygen vacancy.

XPS、ESR测试结果和粉体的显色特性表明：N元素可以由沉淀剂直接引入到TiO_2粉体中，形成间隙型和置换型N掺杂；N占据氧空位的位置对粉体的可见光吸收特性是必要的，同时氮掺杂还可抑制氧空位的再氧化。

The analyses of electronic structures shows that the catalytic reactivities for H2 adsorption of the different surfaces are dependent on the numbers of s orbital bonding electrons around Fermi level for the uppermost layer metal atoms which interact directly with H2. It is easy to form vacancy for hydrogen atoms next to iron atom, which indicates that hydrogen atom cannot be escaped, but it is difficult to from vacancy for hydrogen atoms next to magnesium atom, which indicates that hydrogen atom can be escaped. Hence it is thought that the change of dehydrogenating properties of MgH2 with or without a little iron addition attributes to the weakened bonding between magnesium and hydrogen.

分析电子结构发现：空位缺陷有助H2吸附于Mg表面，与Mg(0001)表面最上层与H2直接产生吸附作用的金属原子在费米能级附近s轨道的成键电子数密切相关；在Fe合金化MgH2体系中，与合金化元素Fe近邻的H原子形成空位的难度增加，H原子较难释放；与Mg近邻的H原子形成空位的难度减少，H原子容易释放；Fe合金化导致Mg-H之间存在较弱的成键作用，因此，MgH2体系的解氢性能得到提高。

The critical shear stress unpinning the 60 dislocation from the ring-shaped hexagonal vacancy defect decreases as the temperature increases in the models, and approaches a stable value of 0.6GPa as the temperature is higher than 300K, bellow the misfit stress in common SiGe heterostructures, which indicates that the 60 dislocation can not be pinned by the ring-shaped hexagonal vacancy defects in this case.

模拟结果表明：使位错不被钉扎住的临界外加剪应力随着温度的上升而减小，在上述模型中当温度达到300K以上就稳定于0.6GPa附近，小于SiGe体系中的失配应力，说明空位缺陷不会成为60位错的钉扎点，仅会对其运动产生迟滞。

The electron location function shows the electronic density changes at both the atomic vacancies and antisites. There is an obvious absence of electronic areas where the vacancy of Ga has the dangling bonds of N, which are favourable for the sdsorption of metal atoms. In contrast, at the vacancy of N, there is more electron distribution(ELF:0.16-0.45), forming lone electron pairs which are profitably available to combine electronegative atoms.

电子局域函数显示了表面空位和替位处的电子密度变化，表面Ga原子空缺处有非常明显的缺电子区域，悬挂键临近N的电子密度增大，有利于对金属原子的吸附；N原子空位处的ELF值为0.16-0.45，有利于同电负性较大的原子结合。

This article starts with the comprehensive understanding of the housing vacancy rate and in-depth comparison of domestic index system with foreign countries'. The article than moves on to the still yet rising housing vacancy situation and the so-caused reason .

本文根据目前我国房地产市场飞速发展同时该领域关于房地产市场是否过热是否存在泡沫等争议不断的现状出发，从国外很好反映房地产行业状况的住宅空置率这一角度切入，试图对我国的房地产市场存在的相关问题和争论进行这一角度的分析。

Education of the speech after the article still discussed a student to enter a college is short of basically miss an appearance, put forward university English speech to receive education into academic rank this one link nots allow to ignore, should fill to differ; and point out it is good to do for student fill a vacancy the key that receives education into academic rank depends on university English teacher wanting to have the concept that values speech education.

文章还讨论了学生进入高校后语音教学基本缺失现象，提出大学英语语音入学衔接教学这一环节不容忽视，要为学生补缺补差；并指出做好入学衔接教学的关键在于大学英语教师要有重视语音教学的理念。

It emphasizes that it is both readers and authors who create the significance and value of literary works together. With the view that literary works have "vacancy" and "suspense", it sums up that there is aesthetic distance somewhat between readers" anticipating horizon and works , and furthermore, Rezeptieasaesthetic will be developed into text-a new theory of readers" mutual communication and conversation.

它强调了文学作品的意义和价值是读者与作者一起创造的，提出文学作品具有"空白"和"未定点"的观点，总结出读者的阅读期待视野与作品之间具有一定审美距离的规律，进而将接受美学发展为文本--读者相互交流与对话的新理论。

NBTI effects can also be influenced by ratio of signal and vacancy. The dynamic characteristics in NBTI degradation was revealed under action of negative and positive gate voltage, degradation can be recovered by positive gate voltage stress.

在负-正-负栅压交替作用下PMOSFET器件中会呈现退化-钝化-退化的动态作用过程，正栅压作用下的PMOSFET器件特性退化会有一定程度的恢复，这是由于在正栅压作用下NBTI反应产物逆向向Si／SiO〓界面处运动从而发生钝化作用造成的。

Results showed that expansion coefficient exhibited anomalous behaviours, which at the -80℃ transition phase point temperature that are caused by Jahn Teller of "Ti—Ba—Ti—"on Barium Titanate, at same time, we also discussed that dielectric constant affected by the rate of vacancy on barium titanate.

结果表明在钛酸钡的三个相变温度点（120℃、8℃、－80℃）处，热膨胀系数反常变化，我们认为相变温度为－80℃处的热膨胀反常是因钛酸钡BaTiO3中对称元"Ti—Ba—Ti"的静态畸变造成。同时本文讨论了BaTiO3中空隙对其介电常数的影响。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
