氧化锌

But water and air have been conspiring to convert it to zinc oxide.

但是在水和空气的共同作用下，锌开始氧化。

Permethylation analysis, periodate oxidation,Smith degradation, acetolysis and partial acid bydrolysis revealed the main chains of XP as mannose of (1-6)-linkages and its side chains were mannose of (1-2)linkages.

甲基化分析、过碘酸盐氧化、Smith降解、乙酰解和部分酸水解显示XP的主链是1→6连接的甘露糖，侧链是1→2连接的甘露糖。1H及13CNMR谱表明所有糖苷键均为a型，结合元素分析XP基本是酵母甘露多糖和蛋白质以及锌的络合物。

Objective: To study the effect of excessive VitA and Zn intake respectively or unitedly on antioxygenic capability, cell cycle and apoptosis protein in the rat spleen. The study wants to confirm the interaction between VitA and Zn, and provide reasonable foundation for the supplement of VitA and Zn.

目的：研究单独及联合过量摄入维生素A、锌对大鼠脾脏抗氧化功能、细胞周期及凋亡相关蛋白的影响，研究VitA和Zn之间的相互作用，为VitA和Zn的合理补充提供实验依据。

The first battery company-Wanli B attery(600874) was public listed in Shanghai Stock Exchange in 1994.In recent te n years, there were about 90 public listed companies invested in battery and its related projects in China including the investment in raw material such as zinc, electrolytic manganese dioxide and investment in lead acid storage battery ,Ni-MH battery,Li-ion battery and fuel cell.

在最近10年中，深圳和上海至少已经有90家上市公司投资过电池及其相关行业，投资的领域涉及各种原材料和电池等，例如锌、电解二氧化锰等，例如铅酸蓄电池、镍氢电池、锂离子电池和燃料电池等，投资的规模达到至少达到60亿元人民币，是中国传统的电池企业无法相比的。

In this thesis, we synthesize eight new compounds 5, 11, 12, 16, 5-Zn, 11-Zn, 12-Zn, 16-Zn, which can be absorbed on the surface of nanometer size semiconductors (TiO_2) with four ester groups on the bipyridyl ligands.

本文合成了八个新化合物5，11，12和16以及它们的金属锌的络合物5-Zn，11-Zn，12-Zn和16-Zn。这些化合物可以通过联吡啶配体的酯基吸附在纳米二氧化钛表面。

AIM: To inverstigate the effects of exogenous Znmetallothionein on antioxidative function and gene expression of SOD in weaning piglets. METHODS: Eighteen piglets (Duroc×Landrace×Yorkshire) were selected and divided into 3 groups (1, 2 and 3) randomly.

目的：用仔猪作模型，研究经锌元素诱导的外源性金属硫蛋白对机体抗氧化功能和超氧化物歧化酶基因表达的影响。

There is a close relationship between AMs morphological and enzymic damage and the production of oxygen free radicals.

其作用机制可能与锌增强AMs抗氧化作用有关，给临床用药提供了理论指导。

The graphite and acetylene black are added to a anode material in making Zn-Mn battery, therefore the sample solution prepared appears as feculency and the titration end point of the solution is difficult to judge when active manganese in the battery is determined by iodimetry with starch as a indicator.

在测定锌锰干电池锰粉中活性二氧化锰含量时，由于制备电池时正极锰粉中添加了乙炔黑、石墨等导电材料，使制得的样品溶液显色且混浊，影响用淀粉作为指示剂进行碘量法滴定终点的判断。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
