Mesoporous zincum sulfide is synthesized by gentle wet chemosynthesis method, with DDA as templates and Zinc acetate and TAA as precursors. The effect to the synthesis of the ratio of reactive components, the volume of pH, reactive time and reactive temperature has been dicussed systematically, and structures of the as-synthesized samples have been characterized by X-ray diffraction, N2 adsorption-desorption, scanning electron microscopy, Fourier transform-infrared spectra, UV-vis diffuse reflectance spectroscopy, transmission electron microscopy.

以十二胺为模板，醋酸锌及硫代乙酰胺为前驱体，温和湿化学法合成了硫化锌无序介孔结构，系统研究了反应物配比、pH值、反应温度、反应时间对材料合成的影响，运用X射线衍射、N2吸附-脱附、扫描电镜、红外光谱、紫外-可见吸收光谱、透射电镜等分析手段对介孔材料的结构进行了详细的表征。

The results were analyzed statistically.Results The incidence of post obturation pain after 1 day in zink oxide paste group was significantly higher than that two groups. The pain occurrence happened 5 or 30 days root canal filling were no difference on them. No statistical difference was observed in success rate on them after 1 year.

结果 Vitapex组和新型根管糊剂组术后1天的疼痛反应较氧化锌组糊剂少，且有显著性差异；5天、30天的疼痛反应则无明显差异；1年后氧化锌组的尖周愈合程度较Vitapex组和新型根管糊剂组差，但已无统计学差异。

At first,the amino group of amino acid esters interacts with the carboxyl group of the amino acid residue of this porphyrinatozinc to form 1:1 adducts.

氨基酸酯的氨基首先与氨基酸残基的羧基作用形成1：1的加合物，然后与锌卟啉的中央锌原子配位形成1：2的加合物，客体分子与主体分子上的氨基酸残基之间的排斥作用以及主客体之间的色散力作用是主体分子能识别客体分子的另外两种作用。

Co-doped ZnO was prepared at the base of the successful synthesis of ZnO. They were charactered and their properties were studied.

Secondly, if you have larger chewing parrots - Asiatics, Conures, Cockatoos etc - do not allow them access to tie wire.

第二，中大型鹦鹉-不可让他们接触那些含高量铅或锌的金属线网//容器，他们有可能因啜咬而吸入或吞下过量的铅或锌。

Comparing with the coppered tubes, the zinced tubes have some important characters, such as low cost, long life and no pollution.

涂锌线管材大量用于制冷和空调设备，与镀铜线管材相比，涂锌线管材具有成本低、使用寿命长和无环境污染等特点。

The results were as follows: Compared with natural growth, defoliating and shielding photosynthesis organs decreased the contents of starch, fat and iron in wheat grains and yields of starch, fat, protein, ash, phosphorus, potassium, zinc, iron and calcium in a single ear.

结果表明，剪叶遮光后小麦籽粒中淀粉、脂肪、铁含量比正常生长降低，灰分、磷、钾、锌、钙含量提高，而对蛋白质含量影响很小；剪叶遮光后小麦籽粒淀粉、脂肪、蛋白质、灰分、磷、钾、锌、铁、钙单穗产量均比正常生长降低。

However, it is organic zinc instead of disassociating inorganic zinc ion that makes effect in the body of animal .
