氧化铝

Thermometric titrimetry has had a long association with the production of alumina from bauxite; where it has traditionally been applied to the determination of the caustic and aluminate contents of recirculating "Bayer Process" liquors.

温度滴定测量长期以来都和从矾土中提炼生产氧化铝有关系–传统上被用来测定再循环拜尔法液体中的苛性碱和铝酸盐的含量。

Run: trisodium phosphate 20,000 tons, 10,000 tons of medicinal mirabilite, 100,000 tons of soda ash, caustic soda, 50,000 tons, 10,000 tons of Aluminum Hydroxide, 4A Zeolite 10,000 tons.

兼营：磷酸三钠 2 万吨，药用芒硝 1 万吨，纯碱 10 万吨，烧碱 5 万吨，氢氧化铝 1 万吨，4A 沸石 1 万吨。

Ache with tristearin, sodium or nitrify cotton is coagulating agent, adopt the legal system of two steps Bei technology, in 65 ℃ respond , shell mellow wine: tristearin acid: the best proportion of the sodium of sodium hydroxide is 91: 6.5: 1, compound with two methods solid shell mellow wine, at the same time join stabilizing agent , eliminate smoke dose , restrain volatilizer and fireworks modifier etc., is as hydration alumina eliminate smoke dose, raise the integral performance of solid shell pure fuel.

以硬脂酸钠或硝化棉为凝固剂，采用两步法制备工艺，在65℃时进行反应，甲醇：硬脂酸：氢氧化钠钠的最佳比例为91：6.5：1，用两种方法配制出的固体甲醇，同时加入稳定剂、消烟剂、抑制挥发剂、焰火改性剂等，如水合氧化铝作为消烟剂，来提高固体甲醇燃料的综合性能。

One such crystal is the ruby, which contains trivalent chromium ions dispersed in a matrix of alumina

这样的晶体有一种叫"红宝石"，它包含的三价铬离子弥散在氧化铝的基体中。

The sorption of trivalent Am and Eu onto TiO_2 and Al_2O_3 was studied by using the batch techniques.

本文用静态法研究了锕系元素中的Am及其类比物Eu在氧化钛及氧化铝上的吸附行为及规律。

We believe this unachievable,especially since alumina tightness is nearly over.

但随着氧化铝紧张态势的缓解，这种可能性越来越小

The adsorptive amount of the unbaked adsorbents loaded with Zn2+ isless than the baked obviously, but the adsorbed amount is not enhanced distinctly bythe way of increasing the baking temperature. The desulfurizing capability increasesdue to the Zn2+ impregnated.

对三种载金属离子吸附剂脱硫性能研究表明，负载锌离子的 13X、氧化铝、5A 分子筛，温度升高，吸附剂的吸附容量升高，硫醇去除率也大，温度升高，增大了活化能克服了势能障碍。

This study attempts to make a solution on how to match the color between glass infiltrating alumina core ceramic and the Vitadur Alpha veneering ceramic.

本研究在已经取得的高强度牙科CAD／CAM用多孔氧化铝材料的研究成果基础上，重点解决玻璃渗透铝瓷着色的问题。

It could be concluded that excellent color compatibility exists between alumina core ceramic infiltrated by No. 1～No. 4 glass powder and the Vitadur Alpha veneering ceramic.

实验证明，自行独立研制的4种具有特定颜色的玻璃粉能够有效地配合Vitadur Alpha饰面瓷完成对自然牙颜色的复现，使牙科CAD／CAM用玻璃渗透氧化铝陶瓷的整体性能达到了临床应用水平。

Finally, four kinds of infiltration glass powder with specified color were developed successfully. The color and its stability of infiltration alumina ceramic were tested. The color match between alumina core ceramic and the Vitadur Alpha veneering ceramic were also tested. The physical and mechanical properties of infiltration glass and alumina core ceramic were investigated.

考察了玻璃渗透后铝瓷的颜色及稳定性，并与VitaIn-Ceram作对比，研究了用自行研制的玻璃粉渗透铝瓷后的颜色与VitadurAlpha饰面瓷的颜色匹配性，测试了渗透玻璃及玻璃渗透铝瓷的物理及力学性能，使CAD／CAM用玻璃渗透氧化铝陶瓷达到临床应用水平。

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。
