氢氧化钛

The basic mechanism of titanium dioxide photocatalytic water-splitting for hydrogen production is introduced.

简单介绍了二氧化钛光催化分解水制氢的基本原理。

Given the current complexity of industrial recovery of 3'-methyl-2'-butenyl 3, 3-dimethyl-pentenoate and the decomposition problems with 2-methyl-1-butene, research was conducted on a process for direct recycling of MBDP involving an ester exchange reaction of MBDP with either methanol, trimethyl orthoacetate, or solutions of methanol and trimethyl orthoacetate.

针对目前工业上回收3，3-二甲基－4-戊烯酸－3'-甲基－2'-丁烯酯工艺复杂、异戊烯大量分解问题，研究了MBDP直接返回循环使用工艺，MBDP与甲醇、原乙酸三甲酯或与甲醇原乙酸三甲酯混合溶液进行酯交换反应的回收新工艺，比较了四异丙基钛酸酯、甲醇钠、氢氧化钾用作酯交换催化剂的效果，筛选出回收MBDP&一锅煮&最佳工艺：按照n：n：n：n＝1.0：9.8：9.2：0.05物质的量比投料，74℃~78℃反应21h，MBDP转化为贲亭酸甲酯和异戊烯醇，单程转化率87.7%，用85%的磷酸中和甲醇钠，蒸出甲醇，直接用于合成贲亭酸甲酯。

The uniform nano-sized titanic oxide mesoporous thin film which can be coated repeatedly was prepared by adding tetrahydrofuran which acts as dispersant to micro-emulsion system consisting of water,cyclohexane,hexadecyl trimethyl ammonium bromide and butyl alcohol.

通过在水、环己烷、十六烷基三甲基溴化铵、正丁醇4组分构成的微乳液体系中加入起分散作用的四氢呋喃，制备出均匀、可重复成膜的纳米氧化钛介孔薄膜。

Transesterification between dimethyl sebacate and 1,2,2,6,6-pentamethyl-4-piperidinol was studied with tetraisopropyl orthotitanate ,lithium amide and di-n-octyltin oxide used separately as catalysts.

对癸二酸二甲酯与1，2，2，6，6-五甲基哌啶醇的酯交换反应进行了研究；分别考察了四异丙基钛酸酯、氨基锂、氧化二辛基锡3种催化剂的性能；采用氢核磁共振确定了产物的结构；考察了以四异丙基钛酸酯为催化剂时反应温度、反应时间、原料配比和催化剂用量对反应的影响。

The reflective coating was prepared with glass bubbles and Al 〓 coated glass bubbles used as pigments. The naked glass bubble went together during the coating drying because its'low density. When the Al 〓 coated glass bubbles used as pigments, the bubbles can be dispersed very well in the dry coating.

空心玻璃微球和氢氧化铝涂层玻璃微球作为填料时，涂料在400nm-2500nm范围内都具有较大反射率；纳米二氧化钛作填料时，在可见光区域具有较大反射，红外区域反射率较小；以纳米二氧化硅作为填料的涂料在整个紫外-可见-近红外区域反射率都很低。

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。

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。
