Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.

同时结合Ti-ZSM-5催化选择性氧化苯乙烯反应的产物分布结果，提出苯乙烯环氧化反应可能是通过金属有机环机理进行；Ti-ZSM-5同时具有催化环氧化和酸催化两种功能，其骨架钛可催化苯乙烯环氧化生成环氧苯乙烷，而骨架钛和骨架铝等可提供Lewis酸位使环氧苯乙烷迅速发生重排生成苯乙醛从而使其成为反应的主要产物，同时还可发生加成以及碳碳键的裂解等副反应：Ti-ZSM-5也提供Bronsted酸位，它也是生成加成产物的活性中心。

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。

The aim of this study was to investigate the effect of oxygen diffusion on the hardness and oxide layer thickness of titanium when the different applying methods of ceramic bonders were used under varies argon supplying conditions.

本篇研究的目的是探讨不同陶瓷黏结剂的使用方式在不同氩气供应的烧瓷环境下氧的扩散对钛金属硬度及氧化层厚度的影响，以期能发现一种可适当控制钛氧化行为的陶瓷烧付程序以利於临床上钛金属-陶瓷赝复物的使用。

The results show that T225NG Ti-alloy has good property of resisting hydrogen brittleness in atmosphere and in loop water. Hydrogen brittleness of T225NG Ti-alloy is hydride brittleness. This is due to the forming of hydride caused by a large amount of hydrogen dissolved in and oxide film on the surface of T225NG ...

研究结果表明：T225NG钛合金在空气和高温高压高纯水的环境下具有良好的抗氢脆性能； T225NG 钛合金的氢脆属于氢化物脆性，这是由于T225NG钛合金中渗入的氢导致氢化物的析出引起的；T225NG钛合金表面氧化膜对它优良的抗氢脆性能起了决定性的作用。

外部层是二氧化钛，然后铁，尼龙和内部的最后一层是由钕。

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。
