When using urea-hydroperoxide as oxygent, just the trimethylphosphine adsorbed on the Lewis acid sites in TS-1 zeolite was oxidized. It further confirmed that the hydroperoxo-titanium species formed by the interaction between the titanium in Lewis acid sites and urea-hydroperoxide are the active oxidation center, and the titanium in the framework as Lewis acid sites enhances the oxidation ability of hydroperoxide. 3. Phenylacetaldehyde and benzaldehyde are found to be the major products in the catalytic oxidation of styrene over TS-1 zeolite, and styrene epoxide is not as speculated detected.

当以过氧化氢尿素为氧化剂时，室温条件下吸附在TS-1分子筛Lewis酸性位的三甲基膦即能被氧化，由此进一步证明，TS-1分子筛中由Lewis酸性位的骨架钛与过氧化氢相互作用形成的过氧化钛物种是三甲基膦氧化反应的活性中心，骨架钛作为Lewis酸中心提高了过氧化氢的氧化能力。

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。

Quadridentate Titanium was detected in the samples with 5% at the low temperature. However, absorption peak of Sexadentate Titanium was not detected at the high temperature. it might not be detected by IR Spectra because of too little Titanium phase.

结果表明，未添加的样品中主要检测到的是硅氧链的变化；添加5%的样品，低温检测到有四配位的钛存在，但是高温时却未检测到六配位的钛离子的吸收峰，这可能是由于生成的含钛晶相太少，红外光谱未能敏感的检测到。

The results show that the water glass has a good selective depression for titanaugite in a weakly acidic medium with pH of 5.5-7.0, which is attributed to the strong action intensity between the water glass and titanaugite, hindering the adsorption of sodium oleate on the surface of titanaugite.

结果表明：在pH=5.5~7.0的弱酸性环境下，水玻璃对钛铁矿与钛辉石的抑制表现出良好的选择性，这是因为水玻璃与钦辉石间的强烈作用阻碍油酸钠在钛辉石表面的吸附，起到抑制作用。

The basic principle for electric smelting of titaniferous slag is introduced and the behaviors of titanium element in DC furnace are analyzed.

介绍了电炉冶炼钛渣的基本原理，分析了直流电炉冶炼钛渣时，钛元素的行为。

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。

In 1973 the Institute of Chemical Metallurgy was engaged to carry out research on fluidizcd roasting of titaniferous iron ore containing vanadium, with the special objective of utilizing the local resources of natural gas and hydraulic electric power, by reduction of the ore with a hydrogen-rich gas followed by melting of the reduced cinder in an electric furnace in order to separate the iron from a slag rich in vanadium and titanium.

化工冶金研究所于1973年接受了&流态化焙烧还原钒钛铁矿&的任务，要求结合当地资源，用天然气还原铁精矿，用水力发电熔化焙砂，再从熔渣中提取钒和钛。我们对流态化还原的若干方面开展了试验研究，包括铁精矿还原反应数据的获得和有关分析，以及可供应用的两种流态化反应器的工程研究。第一种是气控式多层流态化床，第二种是快速流态化反应器。此外，对于流态化还原中的失流以及熔砂的渣～铁分离和从熔渣中提取钒钛，也进行了试验研究。

On the basis of the above,aiming at its characteristics and improving recovery rates of elements,the developing direction of comprehensive utilization of vanadium-bearing titanomagnetite is put forward to realizing the recoveries of iron,vanadium,and titanium all together.

在此基础上，针对钒钛磁铁矿特点和提高元素回收率的目标，提出了今后实现铁、钒、钛全面回收利用的钒钛磁铁矿资源综合利用发展方向。

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。
