Recent progress on surface modifications of TiO2 doped by metal cation and metalloid anion has been summarized,based on the findings reported in the present literatures.

早期的研究主要集中在悬浮体系即TIO：粉末上，但目前悬浮相TIO：光催化剂在水中易凝聚、易失活、且使光的穿透力受阻，尤其是处理后的光催化剂分离与回收的难题已成为该项技术能否工业化的关键。

This does not obligatory mean existence of independent metastability of these traps or their deactivation , but is mainly related with new positions of quasi-Fermi levels when the sample becomes slightly p-type.

观察的过程是：（1）EL2的光淬灭，（2）光致恢复，该过程导致TSC谱中大多数空穴峰的改变，但在PQ前没有TSC峰的再现，（3）用PQ光重照射。

Then, the mechanism and rate constant of the photocatalytic degradation of the methylene blue solution were investigated.

结果显示，反相微乳液法制备的纳米TIO：具有较高的光催化活性，但负载型光催化剂MCM一TIOZ显示更好的光催化活性。

The authors made a group of diagrams which contained the information of minority carrier diffusion lengths in the epitaxial layer and the substrate according to the theoretical analysis.

What could make their skin shine moon-bright like that, or their white-gold hair fan out behind them without wind..

她们的皮肤为什么像月亮一样泛着皎洁的柔光，她们的头发为什么没有风也在脑后飘扬……（她们的皮肤为什么像月亮一样泛着皎洁的柔光，她们闪着白光的金发为什么没有风也在脑后飘扬

The yield and the utilization rate of solar energy and heat increased by more than 20%. It showed that this new multiple cropping pattern is an effective way to further increase yield in this region.

该模式实现高产的关键是充分利用间套作复合群体高强度的纳密功能，并形成一个高光效的群体结构，使复合群体的受光改善和截光能力增强。

Taking the Kubelka-Munk laws as foundation,the light interaction of ink and paper by existing models has been analyzed,including surface reflection of ink and multiple intemal reflection of paper,and light absorption and scattering and so on,the Clapper-Yule color prediction model has been modified aiming at the two possibilities of long and short distance of light scattering in newspaper.

以Kubelka-Munk定律为基础，研究了油墨、新闻纸在印刷中墨层的表面反射、承印物纸张内的多重内反射、墨层内光的吸收和散射，针对其中的光散射距离的长短两种可能，修正了Clapper-Yule颜色预测模型，引入代表长短光散射距离的比例系数h，建立了新的颜色预测模型，计算得到h=0.43。

It has been widely used for the transient light property measurement of different explosive and shells, the light property parameters measurement of plane obstacle avoidance light and ship navigation mark lamp, pulsed Xenon lamp, camera flash light and various luminotrons in solid luminescence. It can also be used to measure source or flames, where are difficultly approached by means of fiber optic guidance. In addition, it finds wide use In medical treatment, biology and chemistry.

如军事上的各种火炸药、各种弹的瞬态光性测量；飞机防撞灯、轮船航标灯的瞬态光性参数测量；脉冲氙灯、照相机闪光灯光性参数测量、以及固体发光学中的各种发光管测量，还可对难以近距离测量的光源或火焰，采用光纤导光的手段进行测量，此外还在医疗、生物、化学等领域有着广泛的应用。

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.
