光和热的

Nanoscale titanium dioxide（TiO2）,a noncombustible and odorless white powder,was widely used in the fields of paints,waste water treatment,sterilization,cosmetics,food additive,and bio-medical ceramic materials,etc.,because of its inherent advantages of the photocatalysis,anticorrosion and high stability. Therefore,it is unavoidable for nanoscale TiO2 to enter the environment and ecological system and to induce the potential biological effects.

纳米二氧化钛（TiO2）因具有良好的光催化特性、耐化学腐蚀性和热稳定性，而被广泛应用于涂料、废水处理、杀菌、化妆品、食品添加剂和生物医用陶瓷材料等与日常生活紧密相关的领域，因此，其将不可避免地进入环境和生态系统中引起相应的生物学效应。

With too much exposure to UV light, your skin overheats and becomes red and painful, and may later peel or blister.

过多暴露于紫外线光，你的皮肤过热而成为红色和痛苦，以及稍后可能会剥离或生殖器疱疹。

The photophysical property of the complex is investigated by means of IR spectra, Raman spectrum and laser excited, high-resolved luminescence spectra which indicates one kind of Eu site with local symmetry of C 2v in the complex.

合成了植物生长素对氯苯氧乙酸和 1，10 邻菲罗林与铕的三元配合物Eu 3·Phen 。对所合成化合物进行了元素分析和热谱分析。通过测定配合物的红外光谱、拉曼光谱和激光激发高分辨荧光光谱研究了配合物的光物理性质。荧光光谱表明配合物中Eu离子只具有一种化学环境，Eu格位的局部对称性是C2v

TiO2/zeolite composite photocatalysts were prepared in the water with natural zaolite and TiCl4, and the structure characterization was carried out by X-ray, IR and TG-DTA. Their photcatalytic reactivity was studied by the methyl orange and methylene blue solution decomposition effect under the sun.

利用天然沸石作载体制备TiO2/沸石复合物光催化材料，从晶相分析和热分析证实以TiCl4为钛源，锐钛矿在水相体系中可直接在沸石表面生成，并牢固结合，同时引起沸石矿物结构的调整。

He respected the knowledge and opinions of other PTG greats such as Owen Jorgensen RPT and Jim Coleman, Sr. RPT who contributed to the capabilities his device and all other devices and software have today.

他尊重知识和意见的其他光敏热成像伟人，如欧文约根森快速成形技术和吉姆科尔曼，快速成形技术谁老作出贡献的能力他的设备和所有其他设备和软件的今天。

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.

交际能力和语法的关系应该是目标与途径的关系。
