本文以无水乙醇作为溶剂，以钛酸四丁脂为钛源，采用溶剂热法制备氧化钛纳米粒子、钛酸纳米管，讨论了产品的形成机理。

The TiO2particles are anatase crystal form with 10-20 nm in diameter, and the SiO2 particlesare uncrystallized. The TiO2 nanoparticles have good photocatalysis degradationproperties, and the kinetics is the first-order to methylene blue.

二氧化钛粒子为锐钛矿晶型，直径10-20nm，但二氧化硅粒子不呈晶态；制备的二氧化钛纳米粒子具有很好的光催化活性，对亚甲基蓝光催化降解符合一级反应动力学方程规律。

Fe-ion doped TiO2 was immobilized on solid support stubstrates-SiOa using sol-gel method. The photocatalytic efficiency of the TiO2 coating was compared with nanosize powders using the degradation of benzophenol in a aqueous solution as a standard test system, the photocatalytic efficiency was found to markedly increase.

采用溶胶凝胶法制备了硅胶附载的掺杂不同量铁离子的二氧化钛薄膜，用XRD，Raman，SEM的手段进行了表征，证明该条件下制备的二氧化钛为锐钛矿相，薄膜在硅胶表面的成膜效果较好，但有一定程度的龟裂，通过光催化实验发现催化效率与纳米粉相比有明显的提高。

Titanium Yellow is a transformation of environmental inorganic pigments, which is consist of titanium dioxide (TiO2), chromium oxide (Cr2O3) antimony oxide (Sb2O5), formed by high temperature calcination.

钛黄是一种转型的环保无机颜料，它是由二氧化钛（TiO2），氧化铬（Cr2O3）氧化锑（Sb2O5），经高温煅烧而成。

The 1%-Ni-doped TiO_2 calcined at 400℃has the best photocatalic ability.An indigo carmine solution of 10 mg/L was completely photodegraded in 50 minutes in the presence of as-obtained photocatalyst under visible light.A series of structure analysis,such as XPS,TEM,are employed to investigate the structure of the Ni/TiO_2 composite in details.The results indicate that at the lower temperature,instead of the simple interface compounding reported by some references,the Ni ions could be inserted into the crystal lattice of TiO_2,and form the innovative material.

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。
