氧化钛

The titanium dioxide is one kind of important industrial chemicals, mainly has the brookite, Rutile and anatase three crystal seeds.

二氧化钛是一种重要的化工原料，主要有板钛矿、金红石和锐钛矿三种晶型。

1The nanocrystalline TiO2 film is prepared by sol-gel and appearance of the film is observed by SEM. The X-ray graph shows the film has lots of anatase and a few rutile TiO2, but does not have brookite TiO2. The average diameter of particle is 25nm according to Scherrer formula.

采用溶胶-凝胶法制备了纳米晶二氧化钛薄膜，通过扫描电镜观察了其形貌，X射线衍射表征显示出制备的薄膜具有大量的锐钛矿晶型和少量的金红石晶型，不含有板钛矿晶型，根据Scherrer公式计算出薄膜的晶粒的平均尺寸为25nm。

Nanosized titania particles consisting of anatase, rutile and brookite phases were synthesized under solvothermal conditions with different alcohols as solvents, hexamethylene tetramine as precipitant as well as precursor of titanium trichloride.

采用不同的醇溶剂，以六亚甲基四胺为沉淀剂，以TiCl3为前驱体，通过溶剂热的方法控制合成出纳米级的锐钛矿型、金红石型和板钛矿型的二氧化钛。

Titanium white used in synthetic fiber is a titanium dioxide of anatase with especial performance and usage.

化纤钛白是一种具有特殊性能和用途的锐钛型二氧化钛。

In general, TiO2 synthesis used precursors for the titanium alkoxide or titanium metal salt which are hydrolyzed and thermal treatment to obtain TiO2 crystals.

传统二氧化钛合成是利用含钛的金属烷氧化物或含钛的金属盐类为前驱体，加以水解及热处理。

Due to this, our goal is to develop a new method to functionalize implant surface by plasma treatment. Argon plasma removes all chemical traces such as adsorbed contaminates and impurities. Oxidation in oxygen plasmas by ion bombardment results in a dense oxide layer.

因此，本研究利用低温电浆来发展一植体表面处理技术，先以氩气电浆清洁钛金属表面，再以氧电浆让钛金属表面产生一层致密的二氧化钛层。

The applications of membrane in the recovery of TiO2 and metatitanic acid particles were described.

本文介绍了国内钛白废液处理的现状，综述了膜法回收偏钛酸粒子和二氧化钛颗粒的应用情况，重

The Ti-enriched slag up to 90--98% TiO_2 may be producedby prereduction of the LUDA ilmenite with plasma smelting.

结果表明，预还原钛铁矿经等离于熔练，可得到含二氧化钛90—98％的富钛渣。

It is concluded that the relative high Al 2O 3 content in titaniferous iron ore leads to increasing of the viscosity and the melting-point of high titanium slag, irregularity in furnace operation and technical-and-economic indexes depression.

认为当钛铁矿中Al2 O3 含量偏高时会导致高钛渣粘度增加，熔点升高、炉况恶化以及指标变坏，同时还会影响二氧化钛的富集及氯化工序的正常生产。

The existence of titanium dioxide and titanyl sulfate reduces the corrosion of zinc deposits.

结果发现：钛的加入能明显提高钝化膜的耐蚀性，这是由于钝化膜中形成二氧化钛和硫酸氧钛，它们掺杂在钝化膜及其腐蚀产物中，有效抑制了锌镀层的腐蚀。

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。
