The simthsonite name derives from English mineralogist James Smithson(1765-1829), who identified two different minerals smithsonite from hemimorphite in 1807, both have long been confused as same mineral, called calamine, used to produce brass, mixed with cupper.

When the concentration of zinc nitrite is lower than 0.1 M,(002) is the prior face for zinc oxide. As the concentration raise, the other kinds of crystal face would appear. Among those data,(002) grows the best when the concentration of zinc nitrite is 0.06 M. We add lactic acid and citric acid respectively; there is an carboxyl group on the lactic acid and three carboxyl groups on the citric acid. The monodentate of lactic acid helps the growth of zinc oxide, compared to the tridentate of citric acid which can only produce zinc oxide film under very low concentration, but the growth of (002) face is not that stable as adding the lactic acid and zinc will electrodeposit to substrate.

实验中，当硝酸锌浓度低於0.1 M 时，氧化锌以(002)面为优选位相，当浓度提高，其他晶面将会出现，当硝酸锌为0.06 M，(002)晶面成长最佳，分别加入乳酸和柠檬酸，乳酸结构上有一羧基团而柠檬酸有三个羧基团，单芽基的乳酸有助於氧化锌成长，对照於三芽基的柠檬酸，则必须在极低的浓度下才能制备氧化锌薄膜，但(002)面成长却没有添加乳酸来的稳定而金属锌也会电沉积到基板上。

Adopting cathode protection of the zinc materials as an effective protection method, which already applied more and more in many field. For example, Hot-dip galvanisation, galvanization, electric arc spray zinc 、sherardizing, etc. But that method are with lots of shortcomings. For example, hard to apply

采用锌材料阴极防护的方式，作为一种有效的钢铁防护手段，已经得到越来越多的应用，诸如热浸镀锌、电镀锌、电弧喷锌、热喷锌等工艺手段，但鉴于这些工艺存在施工难度大、环境污染重、能耗高、锌层受损难修复等弊端，使得发展受限。

通过试验验证了采用锌蒸气压蒸发提纯热浸镀锌渣冷凝后可以直接形成金属锌粉，说明热浸镀锌渣制备金属锌粉的工艺理论是可行的

Zinc sulfide nanoparticles with different sizes were synthesized by a unique precipitate dissolution method using zinc alkyl xanthate and sodium sulfide as zinc and sulfur sources, respectively. The samples synthesized were characterized by low temperature nitrogen adsorption and desorption, Transmission Electron Microscope, powder X-ray Diffraction and Fourier Transform Infrared Spectroscopy techniques.

以烷基黄原酸锌和硫化钠分别为锌源和硫源，采用烷基黄原酸锌沉淀溶解法制备了粒度可调、粒径分布比较窄的面心硫化锌纳米粒子，利用比表面积测定、透射电镜、粉末X射线衍射、傅里叶转换红外光谱等方法对合成的硫化锌纳米粒子进行了表征。

Zinc oxide raw materials and zinc oxide ores, containing high fluorine, chloride and iron, can 't be treated to produces electrowinned zinc by routine process. High-purity zinc using in non-mercury zinc powders is prepared only by using vacuum distillation or rectify process from zinc of the zero grade.

本文针对目前氟、氯、铁等杂质元素高的氧化锌物料、氧化锌矿常规方法难以处理以及无汞合金锌粉用高纯锌必须由0号锌用真空蒸馏或精馏法生产的问题。

A method for the analysis of zinc oxide phase content in sulfide ore was studied. On the basis of the characteristics of each phase component, the sulfide ore sample was leached twice with NaOH and acetic acid-ascorbic acid, respectively, so that the oxide mineral and zinc oxide were dissolved completely. The leaching rate of zinc oxide phase was up to 98 Vo. Moreover, the dissolution of zinc sulfide phase was effectively inhibited, solving the problems of selective leaching and determination for zinc oxide.

研究了硫化矿中氧化锌相含量的分析方法，根据硫化矿中各物相组分特点，提出了用氢氧化钠溶液和乙酸－抗坏血酸溶液二次浸取硫化矿，使锌氧化矿、氧化锌充分溶解，氧化锌相的浸取率达到98%以上，同时有效地抑制了硫化锌相的溶解，较好地解决了氧化锌相选择溶解测定的问题。
