研究了疏水性添加剂脂肪酸类阴离子表面活性剂与21-碳烷不同配比对铝酸钠溶液分解产生氢氧化铝和氧化铝的粒度、强度及分解率的影响，考察了产物Al3和Al2O3的强度和粒度之间的关系，探讨了添加剂影响铝酸钠溶液晶种分解的相关机理。

The effect of hydrophobic additive on the seed precipitation from sodium aluminate solution was studied by adding fatty acid and heneicosane at different proportions. The results show that when the mass fraction of fatty acid is in the range of 32%-49% and the additive concentration in sodium aluminate solution is 150×10-6 g/L, the rate of precipitation increases, but the particle size of Al3 and Al2O3 reduces.

The quality is a burnt magnesia spinel brick made from fused magnesia, low iron sintered magnesia and fused hercynite.This synthetic hercynite is a patent by RHI Refractories.

它由电熔镁砂、低铁烧结镁砂和电熔铁铝尖晶石制成的烧结镁铁尖晶石砖，这种人工合成的铁铝尖晶石是RHI奥镁公司的专利。

We assumed that after the PACl〓 was dosed into water, its hydrolysis-aggregation-precipitation process combined the most popular"core-link"or hexameric ring scheme and the more recent model of polynuclear formation involving a typical specie of tridecameric,〓. The integrate pattern can nicely explained the phenomena.

另外，研究表明，PACl中预制的Alb形态和铝盐在混凝过程投加入水后形成的Alb形态在稳定性上有很大的区别，这无疑是由于它们的化学结构上的不同造成的，推测铝盐在投加入水后，其水解聚合过程按&六元环&模式〓和&核环&模式〓结合进行，这种综合模式可以很好的解释实验中的现象。

The experimental result shows that the resonance line w,the magnetic quadrupole M2 line,the intercombination line y and the forbidden line z of He-like Al are obtained with PET crystal in the direction of horizontal.

实验结果表明，PET晶体分光效果理想，获得了铝的类He共振线、磁四级M2跃迁x线、互组合跃迁y线以及禁戒谱线z线，适合于研究X射线极化光谱学；云母晶体得到铝的类He共振线，其伴线光谱不明显。

Secondary growth of silicalite-1-seeded industrial CuO-ZnO-Al2O3 in alkaline solution with silica and alumina source produced intergrown ZSM-5 zeolite shells. After the shells were changed into HZSM-5, we compared the catalytical performance of the core/shell composite catalyst with a non-core/shell structured composite catalyst with the same component.

铜锌铝催化剂（CuO-ZnO-Al2O3）是工业上制备二甲醚的良好催化剂，我们将其表面预先包覆纳米沸石silicalite-1晶种，水热环境下二次生长后吸收硅源、铝源后形成ZSM-5膜，转换成氢型后形成CuO-ZnO-Al2O3/HZSM-5的核/壳结构复合催化剂。

Research results of phase equilibrium for the KOH—K〓CrO〓—H〓O system, the KOH—KAlO〓—H〓O system and the KOH—K〓CrO〓—KAlO〓—H〓O system revealed that lower concentration of KOH was beneficial for the crystallization of KAlO〓, and within a certain range, higher concentration of KOH was favorable for the crystallization of K〓CrO〓.

KOH—K〓CrO〓—H〓O体系，KOH—KAlO〓—H〓O体系和KOH—K〓CrO〓—KAlO〓—H〓O体系相平衡研究结果表明，较低的氢氧化钾浓度有利于铝酸钾结晶析出，一定范围内，较高的氢氧化钾浓度有利于铬酸钾结晶析出，因此，通过控制氢氧化钾浓度可以使铬酸钾—铝酸钾—氢氧化钾得以分离。
