For examples, in field trials, the plant alpine pennycress removed zinc and cadmium from soils near a zinc smelter, and Indian mustard, native to Pakistan and India, has been effective in reducing levels of selenium salts by 50 percent in contaminated soils.

举例来说，在实地试验中，高山菥蓂从靠近一个锌冶炼厂的土壤中去除了锌和镉，原产自巴基斯坦和印度的印度芥菜可以将染土壤中硒的水平有效地降低50%。

Silver has two forms in its occurrence:mainly in the form of silver-bear iug sulfosalts(pyrargyrite,freibergite and Ag,Zn-bearing tetrahedrite and others) discovered for the first time;secondary,in the form of impurities scattered in the memllic sulfides.

银主要以首次发现的含银硫盐矿物（深红银矿、银黝铜矿和含银锌黝铜矿等）产出，其次是杂质元素分散在金属硫化物中，银的含量按方铅矿、黄铜矿、闪锌矿、黄铁矿的顺序依次降低。

So it usually needs to roughen the surface toimprove the bonding strength. But the coarseness was not used in this paper. The technique ofarc spraying zinc in advance and then arc spraying copper was put forward to solve the problemof bonding strength.

而本研究根据锌喷涂层具有较好的附着性，提出了在电铸层上先喷涂锌后喷涂铜的工艺路线，较好地解决了铜喷涂层与电铸层结合强度偏低的问题。

The results show that the diameter of nanosphere is about 20 nm, and it has obviously blue shif compared with the conventional bulk material zinc selenium, which indicate that the synthesis of zinc selenide nanoparticles has excellent optical properties.

结果表明，所得纳米球体直径约20nm，与常规体材料硒化锌相比发生明显的蓝移现象，说明所合成的硒化锌纳米球具有优异的光学性能。

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。

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。

Therelationship between solution rate of Al/TiC alloy in rotating Zn melting and thetemperature of Zn melting, rotating rate of axis and uniformization time wascalculated.

分析了各工艺参数对Al／TiC预制合金在锌液中溶解速度的影响，建立了Al／TiC合金在锌液中的溶解率与各参数间的关系式。
