钛酸盐

The calculation method represented in this paper is very simple and convenient. By comparing the relative errors, the method is better than other methods. Moreover, it can be used to calculate molar Gibbs free energy and molar enthalpy of formation of all complex oxysalt minerals including a series of titanate whiskers that author's group has studied for many years. The thermodynamic data for the series of titanate whiskers provide necessary fundamentals to their preparation.

本文提出的方法计算步骤十分简单，从相对误差来看，本方法和其他方法相比精度较好，可以计算包含本课题组长期研究的钛酸盐系列晶须的所有复杂含氧盐矿物的摩尔生成Gibbs自由能和摩尔生成焓，为热力学在钛酸盐系列晶须制备中的应用提供理论支持。

A method of increasing the lifetime of a hydro-oxidation catalyst comprising, preferably, gold, silver, or mixtures thereof, and optionally one or more promoters, on a titanium-containing support, such as a titanosilicate or titanium dispersed on silica.

一种延长加氢-氧化催化剂寿命期的方法，该催化剂在比如硅钛酸盐或分散在氧化硅上的钛的上面优选含有金、银或它们的混合物，以及任选的一种或几种促进剂。

These results above indicated that ordered mesoporous titanosilicate with different Si/Ti molar ratio could be obtained using trimeric surfactant C_(14-2-14-2-14) as templating agent and the Si/Ti ratio could be as low as 5 without the losing of mesostructure ordering.

上述结果说明以自组装能力强的三聚表面活性剂C_(14-2-14-2-14)为模板剂可以制得不同钛含量的介孔硅钛酸盐材料，尤其是可以得到Si／Ti比低至5的高钛含量介孔硅钛酸盐材料，这对于提高此类材料的氧化催化性能有重要意义。

Treatment at a high temperature would bring big changes to the structures of titanate nanotubes. When the calcination temperature was higher than 450℃, the tubulous structure of titanate nanotubes was destroyed and transformed into anatase phase.

高温煅烧处理对钛酸盐纳米管的结构影响较大，当温度高于450 ℃后，纳米管的层状结构被破坏，晶体结构转化为锐钛矿相的TiO2结构。

These specific absorption bands are in relation to the special energy levels.

人们经过十多年的时间，对钛酸盐纳米管的组成、形成机理和物理化学性能进行了大量的研究，但是到目前为止，研究者对其形成机理、可见光吸收等特殊光电性质的来源、结构稳定性等方面的认识尚不清楚，因此本论文对这些方面开展了如下研究：在第二章中我们从热力学的角度系统地研究了煅烧温度对钛酸盐纳米管形貌、结构稳定性和光学性能的影响，发现钛酸钠纳米管是热力学稳定的，而钛酸纳米管是热力学不稳定的。

After the sodium in titantes was substituted completely by hydrogen ion in dilute acid and annealed, nanostructured titanium dioxides anatase, TiO2(B and rutile retained the morphologies in titante state were obtained.

将产物以稀酸溶液进行完全的氢离子取代并加以热处理后，可得到维持原来钛酸盐阶段形貌的二氧化钛(锐钛矿、B型二氧化钛或金红石相)奈米结构。

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。
