铵明矾

Below is a new process of synthesizing ammonium alum by means of semifinished aluminium sulfate and the mother liquor from the preparation of sodium carbonate through double decomposition as raw materials.

研究了以芒硝复分解法制碳酸钠的母液和粗品硫酸铝为原料合成铵明矾的工艺，找出最佳工艺条件，产品质量达到国家标

Ultrafine γ-Al 2O 3 particles were prepared by thermal decomposition of ammonium alum .

铵明矾加热分解可制得超细γ－Al2O3粉末，进一步灼烧可制得α－Al2O3微粉。

Prepared the ammonium alum injection, tested it's stability, security, contain of ammonium alum、pH value and osmotic pressure. All results were corresponded with the quality requirement of vein injection. The effect of Ammonium alum injection was similar to alum injection to treatment cyanide poisoned rabbits.

通过铵明矾注射液制备、其稳定性、安全性的试验结果显示铵明矾注射液有效成分、标示量、pH值、渗透压、稳定性等指标符合静脉注射剂的质量要求，铵明矾也有与明矾类似的抗氰效果。

But in the course of internationalization, they meet with misunderstanding and puzzlement.

许多企业已经意识到了这一点，但在国际化的进程中，仍存在一些误区与困惑。

Inorder toaccomplish this goal as quickly as possible, we'll beteamingup with anexperienced group of modelers, skinners, and animatorswhosenames willbe announced in the coming weeks.

为了尽快实现这个目标，我们在未来数周内将公布与一些有经验的模型、皮肤、动画制作小组合作。
