钛

At the same time, because of ilmenite content in the ore is relative higher, that is advantageous to recovery of titanium and high recovery could be obtained.

同时，矿石中钛铁矿含量相对较高，有利于钛的回收，可获得较高回收率。

Main useful minerals in these two ore belts include anatase, rutile and ilmenite.

这2个矿带的主要有用矿物为锐钛矿、金红石及钛铁矿。

The decomposing kinetics of ilmenite in KOH sub-molten salt was investigated. The effects of factors, such as reaction temperature and particle size of the ore, on the decomposition rate of ilmenite were also studied.

摘 要：对钛铁矿在氢氧化钾亚熔盐体系中的分解动力学进行研究，考察反应温度及矿粒粒径对钛铁矿分解率的影响。

One of the most favorite titanium jewelry pieces in the market are titanium rings.

最喜爱的钛市场的珠宝作品之一是钛环。

The substituted half-sandwich titaconece with bulky alkoxyl group [CpTiC1〓 or CpTi 〓] or indene ring can not be fluorinated by BF〓·Et〓O under the selected condition, but still coordinates with the BF〓, this coordination then enhances the steric effect that stabilizes the precursor and hinders the reduction of the Ti to the Ti species, reflected in the decrease in polymerization activity.

但是这个转化受主催化剂分子的空间位阻和聚合反应温度的影响，当主催化剂为大位阻的烷氧基取代茂钛络合物或茚钛络合物时，在一般的聚合温度下BF〓不能对它们进行氟化，但可以和其中的OR配位，这种配位进一步加剧了空间位阻，从而阻碍了活性中心的形成，导致催化活性的下降。

Zaarin sent his own Interdictor, the Maelstrom, as well as several squadrons of TIE Advanced and Defender craft to eradicate Thrawn's task force, while he assaulted the second Missile Boat convoy.

扎林在进攻第二支飞弹艇运输队的同时，派出了自己的阻绝者舰"大漩涡"号以及另外数支先进型钛战机、钛防御机中队消灭索龙的特遣部队。

Microplates has stable property and easy to reconstruct. It is stable and practicable. Surgical treatment can avoid intermaxillary elastic traction or reduce traction time, it is a good method for treating condylar fracture.

微型钛板性能稳定、改建成形容易，钛板内固定稳定可靠，手术治疗可免除颌间牵引或缩短颌间牵引时间，是治疗髁突骨折的良好方法。

Methods: We exposured the location of the fractures (except mandibular ramus and condylar fracture) through intraoral incision approach, then using titanium neil to reposition the fractures as an anchorage. After restitution the occluding relation, we used minitype titanium board for rigid internal fixation without intermaxillary wiring.

18例患者均采用口内入路暴露下颌骨骨折部位，用钛钉作支抗复位下颌骨骨折，恢复其咬合关系后，用小型钛板作坚固内固定，术后不行颌间结扎。

A plausible charge distribution of Fe and Mo valence states is proposed, and the stability of the compounds is discussed. Polycrystalline samples of 〓(0.8≤x≤1. 5) are prepared by solid-state reaction at high temperature. The alteration of the relative content between Fe and Mo in 〓 exhibits a significant effect on the crystal structure and the ionic ordering of the compounds.

采用传统高温固相烧结反应法合成了非化学配比的双钙钛矿型〓系列化合物。X射线粉末衍射数据分析结果表明，非化学配比的双钙钛矿结构〓（0.8≤x≤1.5）系列化合物的晶体结构随着Fe含量x的变化在x=1.2附近有一个由四方14/mmm对称向立方Fm〓m对称的结构结构相变发生。

By means of X-ray diffraction, nitrogen adsorption, UV-Vis diffuse reflectance, a successful isomorphous substitution of titanium in the silica framework of SBA-15 samples with Si/Ti = 50, 25, 20 has been proved, the substitution of Ti for Si does not change the highly ordered two-dimensional hexagonal mesostructure of SBA-15. Titanium is totally tetrahedral and highly dispersed.

通过X射线衍射、N2气吸附脱附、紫外—可见漫反射等表征手段，证明在Si/Ti＝50，25，20时，钛原子成功地取代了SBA-15中的硅原子而没有改变SBA-15高度有序的介孔二维六角结构，其中钛全部以四配位状态存在，而且高度分散。

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。
