测定了3种不同氧化层厚度的氘化钛在873～1073K范围内的热解吸反应速率常数，得到673K下氧化5、2h的氘化钛和未经氧化处理的氘化钛热解吸氘的活化能分别为29。

The deuterium thermal desorption behavior of titanium deuteride with or without anodic oxide layer on the surface in a constant volume system has been investigated in the temperature range of 600℃ to 800℃.

A novel carbonyl transposition led by anilines'nucleophilic addition to methyl 2-keto α-D-glucopyranoside was discovered. And the mechanism of the reaction concerned to an enol rearrangment was provided through tracing the change of 〓H-NMR and 〓C-NMR of a hemiacetal intermediate which was obtained in the reaction of o-phenylene diamine with 2-keto glycoside. Both the intermediate and the converting product were identified by 〓H-NMR,〓C-NMR,〓H-〓H COSY and HMQC.

一、发现了2-位氧化α-甲基D-葡萄糖苷的芳胺亲核加成引起羰基转位的新方法，利用核磁共振氢谱及碳谱对邻苯二胺与2-位氧化α-甲基D-葡萄糖苷加成生成的稳定中间体半缩酮化合物在氘代丙酮中的变化进行跟踪，结合对转化产物的氢氢相关谱和HMQC结构确证，提出了该反应中2-位羰基通过烯醇化互变而转至3-位的机理并得到了验证。

Arata used pressure to force deuterium gas into an evacuated cell that contained a palladium and zirconium oxide mix(ZrO2-Pd).

arata使用的压力，迫使氘气进入一疏散细胞载有钯和氧化锆的组合。

The photodegradation rate of M-PPV 1 was constrained by DABCO that quenches the triplet state of M-PPV; 2increased when the solvent changed from benzene to deuterated benzene in whichthe lifetime of triplet state is longer than that in benzene; 3 was improveddramatically with high concentration of M-PPV triplet state was generated by energytrasfer from biacetyl.

发现：1能猝灭M-PPV的三重态的1，4-二氮二环[2.2.2]辛烷也能有效地抑制光氧化反应的进行；2能提高M-PPV三重态寿命的氘代溶剂也能使M-PPV光氧化降解速率加快，3丁二酮和M-PPV间的能量传递能够提高M-PPV三重态的浓度，这和丁二酮作三重态敏化剂敏化光氧化M-PPV时，M-PPV的光降解速率大大增加也是一致的。

"Water from most natural sources contains about 0.015% deuterium oxide; this can be enriched or purified by distillation, electrolysis, or chemical processing."

大多数来自天然水源的普通水约含有0.015%的氧化氘，可透过蒸馏、电解或化学过程来提高或去除其含量。
