空穴

When smooth accelerant is shot by illumination, change smooth energy into electron and cavity above all, next with the oxygen in air (O2) and water element (H2O) reaction, the oxyhydrogen that generates a freeboard oxidation capacity is free base and oxygen anion (O2-).

光触媒被光照射时，把光的能量首先转化成电子和空穴，然后与空气中的氧气(O2)和水分子(H2O)反应，产生具超高氧化能力的氢氧自由基和氧负离子(O2-)。

It is found that partial substitution of Sr for La induces the hole carrier evidenced by positive thermoelectric power but no bulk superconductivity is observed.

通过热电势的测量，我们发现在LaFeAsO中用少量的Sr部分取代La所获得的样品热电势为正值，说明体系中被引入了空穴载流子，但是并没有观察到超导电性。

At the same time, the velocity of forming electron-hole pair is more than that of complex and so the photocurrent increases.

这主要是由于它们本身是半导体，也可产生电子-空穴对，并产生的速率大于通过复合中心复合的速率，从而增大光电流。

Chapter 4. Due to their large specific surface area and the photogenerated electron-hole pairs under solar illumination, semiconductor NPs have been used as catalysts in the photodecomposition of organic pollutants.

第四章，半导体纳米粒子由于拥有高的比表面积，且可以吸收太阳光并且发生电子和空穴的分离，是一类高效的有机污染物光降解反应的催化剂。

The experiments show that TiO〓 nanowire arrays have higher photodecomposition efficiency than TiO〓 film. It is due to not only their higher surface area, but also their wider energy gap. 6. Ordered NiO nanowire arrays embedded in anodic alumina membranes have been prepared by using an electrochemical deposition method. Thermogravimetry curve shows that NiOH embedded in AAO decomposed slowly compared to thin film.

可能存在两个原因：氧化钛纳米丝具有比氧化钛纳米膜更大的比表面积；氧化钛纳米丝的光学带隙大于氧化钛纳米膜的，带宽的增加，使得价带电子电位变得更正，导带电位变得更负，这实际上增加了光生电子和空穴的氧化还原能力，提高了半导体光催化氧化有机物的活性。

Compared with the ordinary TiO2 thin film electrode, the metal doping and the superficial gable is helpful for separating the electron and the hole. The solar cell's short circuit photoelectric current enhanced by 16% and the electro-optic transfer efficiency enhanced by 17%.

与改性前的TiO2薄膜电极相比，金属掺杂和表面包覆有助于光生电子和空穴有效地分离，电池的短路光电流提高了16%，光电转换效率提高了17%。

Through photoemission experiments,the 3d- 4s hybridization and very high density of 3d states can be demonstrated clearly.

由于杂化使得3d带的空穴参与了导电过程，而高的态密度使其具有极高的有效质量。

Refractive index is one of fundamental physical constant, which is often related to concentration, temperature, void fraction, internal strain etc.

折射率是一个基本物理量，通过它可以跟浓度、温度、空穴率、内应力等联系起来，因此折射率的测量很重要。

Due to the modulation of the piezoelectricity, a hole well is formed.

表明在栅压和压电极化场的共同作用下，可以形成的空穴聚集。

Hole - Similar to a positive charge, this is caused by the absence of a valence electron.

空穴 -和正电荷类似，是由缺少价电子引起的。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
