The X-ray diffraction results of corrosion products and scanning electron microscopy analysis of corrosion surface were used to comparatively investigate the corrosion properties of Zn/Al coatings, and to study the self-sealing mechanism.

研究表明，与纯锌、纯铝涂层相比，对于钢基体，锌铝复合涂层具有更加合适的阴极保护电位，可以大大提高防护寿命；海水环境中涂层表面会形成一层致密稳定的腐蚀产物膜，能有效阻止腐蚀介质向涂层内部的渗透，涂层会保持在一个较低的腐蚀速度。

To introduce the control principle,spelter pot structure and its characteristics,the property characteristics of IPC6500 oil burning spelter pot for galvanizing by dipping.

介绍IPC6 5 0 0型热镀锌燃油锌锅的控制原理、炉型结构及特点，设备的性能特点，给出了控制电路图和燃油机结构示意图，指出该设备的油耗仅为 6～ 12kg/h ，是电加热方式生产费用的 2 0 %～ 30 %，并且能有效防止钢丝过热，延长锌锅寿命

Organozinc reagents can react with a variety of α,β-acetylenic ketones and aldehydes in the absence of any catalyst. The one-pot reaction affords β-branched Baylis-Hillman type adducts, the multifunctionalized alkenes, in excellent yields with high stereoselectivity.

这种顺式亲核加成反应的发生是由于该类有机锌试剂既具有较强的亲核性，又具有Lewis酸的特性，使有机锌中R基团从同位进攻中心碳原子而形成新的碳碳键。

An experiment was conducted to evaluate excretive tendency of zinc in feces and urine with 8 goats groups fed with diet Ⅰ(basal diet+ 65 Zn Met) and diet Ⅱ(basal diet+ 65 ZnSO 4) respectively.

8只体重为9kg左右的健康浏阳黑公山羊，分成两组，单独关在代谢笼内，分别喂以含65Zn蛋氨酸（65ZnMet）和65Zn硫酸锌（65ZnSO4）的饲料，比较研究锌蛋氨酸螯合物的中锌在山羊粪、尿中的排泄动态。

The results show that the maximum growth quantity of Nocardia can be achieved after culturing 120 h and obvious selective adsorption of Nocardia on the surface of pyrite and sphalerite can be detected. The maximum adsorption rate on the surface of pyrite is 96.99%, whereas it is less than 20% in the case of sphalerite. Adsorption equilibrium can be attained within 20 min on the surfaces of the two minerals. pH value is the key factor influencing upon selective adsorption, and the difference of adsorption quantity on the surfaces of two minerals is apparent when pH is between 4 and 10. Slurry concentration over 6 g/L is favorable to selective adsorption. Nocardia cell concentration, stirring speed and temperature have no obviously effect on selective adsorption.

结果表明：培养120 h后诺卡氏菌达到最大生长量；诺卡氏菌在黄铁矿和闪锌矿表面发生明显的选择性吸附，在黄铁矿表面的最大吸附率可达到96.99％，而在闪锌矿表面的吸附率大都在20％以下；诺卡氏菌在两种矿物表面于20 min内即可达到吸附平衡； pH值是影响诺卡氏菌在两种矿物表面发生选择性吸附的关键因素， pH在4～10之间时，选择性吸附现象明显；矿浆浓度超过6 g/L时有利于发生选择性吸附；细胞悬浊液浓度、搅拌速度和温度对吸附效果影响不大，均可产生选择性吸附。

Through this research,we extended the appliacation of organozinc reagents in organic synthesis.

通过这些研究，我们扩展了有机锌试剂的应用范围，提供了高产率的合成γ-羰基酯化合物的有效方法在第三章中，我们研究了有机锌试剂在Baylis-Hillman类型反应中的应用。

If you have diabetes or if your pancreas is overworked or weak, you will not be excreting enough picolinic acid and will not be providing enough zinc to your brain and you will need to supplement your diet with zinc.

如果你有糖尿病或如果你是胰腺过度或弱，你不会分泌足够的烟酸，而不会提供足够的锌，你的大脑和你将需要补充您的饮食与锌。

A clean production technology of sodium sulfoxylate formaldehyde by one-step process with sodium pyrosulfite ,zinc powder and formaldehyde as raw materials was studied in detail.

详细研究了以焦亚硫酸钠、锌粉和甲醛为原料，一步法合成甲醛合次硫酸氢钠的清洁生产工艺，其最佳操作条件为：焦亚硫酸钠与锌粉物质的量比约1∶2.5，焦亚硫酸钠与甲醛物质的量比约1∶2.1，亚硫酸氢钠溶液的pH 3.3~3.6，活化温度≤45℃，最高温度97~102℃，高温反应时间
