尖晶石

There are also purples spinels, and those colors range from purple to blue and blue-green and then move into inky color ranges.

还有紫色尖晶石，这些颜色从蓝色和紫色蓝绿色范围，然后进入漆黑的色彩范围。

The crown, which dates back to 1347, is made of solid gold and is decorated with precious gemstones such as sapphires, emeralds, spinels and pearls.

冠，可追溯到1347年，是由坚实的黄金和装饰有珍贵的宝石，如蓝宝石，祖母绿，尖晶石和珍珠。

Spinels were enriched by compounds of magnesia and alumina.

尖晶石丰富了镁和氧化铝化合物。

Spinels were enriched by compounds of magnesia and alumina.

尖晶石化合物丰富了镁和氧化铝。

Fine spinels are often set in handcrafted one-of-a-kind jewelry by custom goldsmiths, since these gems are too rare to be cut in standardized sizes.

手工订罚款尖晶石往往一-一-样的风俗金银首饰、因为这些都是太稀有宝石规范将裁减大小。

It is called the cobalt spinel which was found in Sri Lanka.

这就是所谓的钴尖晶石被发现在斯里兰卡。

In this group, spinel (MgOAl2O3) and chromium spinel (MgO-Cr2O3) are the most important minerals applied in industry.

镁铝尖晶石耐火材料是目前冶金用耐火材料的重点发展方向之一，对这种材料的理论及应用研究也成为耐火材料研究的热点。

Case in point: the Black Prince's Ruby on the British Imperial State Crown is a magnificent 170-carat red spinel.

例证：黑色太子红宝石英帝国的皇冠是一个宏伟的国家170克拉红色尖晶石。

The results indicate that the cell only doped with Al2O3 (Cell 1) is of the worst output performance at 850 ℃, the output power density being 0. 083 W/cm^2, and that the cell doped with Al2O3 and coated with buffer layer (Cell 2) is of the best output performance at the same temperature, the output power density being 0.120W/cm^2. AC impedance spectroscopy analyses indicate that the interface resistance and Ohmic resistance of Cell 2 are obviously less than those of Cell 1, meaning that insulative nickel aluminum spine1 is generated by the reaction of Al2O3 and NiO during the sintering at a high temperature.

结果表明：850℃时，含Al2O3的电池输出性能最差，输出功率约为0.083 W/平方公分；含Al2O3并具有过渡层的电池输出性能最好，输出功率约为0.120 W/平方公分；交流阻抗谱分析表明，含Al2O3并具有过渡层的电池的欧姆电阻与界面电阻均比不含过渡层的明显减小，说明YSZ中添加的Al2O3在高温烧结过程中，与阳极材料NiO发生反应生成不导电的镍铝尖晶石。

The total precipitation for the law synthetic micrometres belt burr of Tansuanli (Li2CO3) and carbonic acid manganese (MnCO3) ball for damages caused calcine material prepared by a porous spherical type of spinel LiMn2O4 as a lithium-ion batteries positive materials, and through the valuable objects to the modified surface active agent, scattered porous ball into nano particles.

高手帮我翻一下。谢谢本文以共沉淀法合成微米级的带毛刺的碳酸锂（Li2CO3）和碳酸锰（MnCO3）球为前驱物通过高温煅烧而制备出多孔球状的尖晶石型LiMn2O4作为锂离子电池的正极材料，同时通过对前驱物加表面活性剂的改性，分散多孔球而成为纳米粒子。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
