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。

The results showed that at the onset of this disease, the serum zinc concentration of 20 patients was lower than the limit of the normal value, and the mean concentration of serum zinc in patients was significantly lower than that of the control group.

在 4 1例白血病患儿和 3 3例正常对照儿童中，观察到在明确诊断化疗前，4 1例白血病患儿中有 2 0例患儿的血清锌浓度低于正常低限，他们的平均血清锌浓度为 1 2 3± 3 4 μmol/L ，明显低于对照组 1 8 3± 4 0 μmol/L。

The mineralization of gold and silver is zoned and closely related to silicification of carbonate and clastic rocks, so siliceous ore dominates in the deposit.

矿化温度主要在300～170 C之间，成矿流体的主要成分为K~-、Na~-、Ca~(2+)、Mg~(2+)、Cl~。金属配合物的分配计算显示，金在成矿热液中主要以疏氢配合物迁移，而银、铁、铅、锌则以氯配合物为主，铁、铅、锌在成矿后期的中性-弱碱性环境下可转变为羟基和硫氢配合物。

The experiments show that Zn〓 play a role of cathode depressant on natural siver flotation.

通过研究锌离子对自然银-捕收剂作用的影响，发现锌离子起阴极型抑制作用。

Pure Zn refined from spelter in Pb and Zn production is a very complex technical process, which needs series work. There is every probability of appearing fault because of the large quantity of facility in production, so that it causes serious effect to the production and security.

铅锌生产中将粗锌精炼成为精锌是一个需要连续作业的复杂工艺过程，所涉及的生产设备较多，发生故障的可能性增大，以至对生产或安全造成严重影响。

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

Marmatite was much easier to be oxidized through electrochemistry than sphalerite.

与闪锌矿相比，铁闪锌矿更易发生电化学氧化。

The modified sphalerite particles were characterized by dispersion experiments, determination of adsorption rate of oil, FT-IR spectra and X-ray photoelectron spectra.

为了克服锌精矿颗粒在浸出液中的聚团问题，减少有机溶剂的夹带损失，采用表面活性剂海藻酸钠对锌精矿进行表面改性研究。

The simulation of Fe doped sphalerite (110) surface and Cu adsorption on the sphalerite surface were performed by using plane wave-pseudopotential approach based on density-functional theory.

摘 要：采用基于密度泛函理论的平面波赝势法对含铁杂质闪锌矿(110)表面电子结构及铜在闪锌矿表面的吸附进行模拟。

The properties of zinc stannate and zinc hydroxystannate as flame retardant and smoke suppression agents are briefly introduced.

简要介绍了阻燃抑烟剂锡酸锌和羟基锡酸锌的性质，综述了它们的制备方法、应用范围及阻燃和抑烟机理的研究进展。

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。
