The result s show that the cerium compounds consist of Ce 3/ Ce 4 and Ce 2O 3/ CeO 2 , exist in the form of particles and are excellently dist ributed on the zinc powder subst rate. The capacity-loss of the zinc elect rodes is evidently suppressed while the discharge capacity and cycle life can be markedly improved due to the application of the zinc-based composite powder as negative materials of the silver-zinc bat tery. Especially , discharge capacity of 231. 4 mAh g-1 is still achieved at the 50th cycle for the zinc elect rode using the composite powder .

结果表明：由 Ce 3/ Ce 4和 Ce 2O 3/ CeO 2组成的铈化合物以颗粒形式良好地分散在锌粉基体上，用这种锌基复合粉作为模拟锌银电池的负极材料，其锌电极的容量衰减得到明显抑制，放电容量和循环寿命得到显著提高，尤其是其锌电极在 50周期的放电容量仍可达到 231。

The concentrate is brought to a temperature of more than 900°C where zinc sulphide converts into the more active zinc oxide.

当锌精矿加热到超过900℃时，硫化锌转变成更活泼的氧化锌。

By using phenolphthalein and methyl orange as indicators, free alkali, zinc and sodium carbonate were titrated with hydrochloric acid and zinc was titrated with EDTA.

提出了EDTA络合滴定和酸碱滴定联合测定碱法炼锌中含锌碱性溶液中游离碱、锌和碳酸钠的新方法。

The good corrosion resistance of hot dip galvanized steel products in nature environments is due to the formation of a protective basic zinc carbonate film on the surface of the zinc coatings.

热浸镀锌表面会生成具良好保护性的碳酸锌膜，保护锌材在一般环境中不致腐蚀太快。
