The spinel LiMn2O4 is synthesized by the citrous acid method. The X-ray diffraction pattern of LiMn2O4 show that the product is a spinel phase with a=0.824nm cubic unit cell.

论文首先采用柠檬酸配位法制备尖晶石型LiMn2O4，X射线衍射证实了产物的结构，晶胞参数a=0.824nm。

Spinel is a cubic system and should show 4 ray star, from crystalographical point of view.

但实际上尖晶石是等轴晶系，应该具有四条十字型的星线。

There are alexandrite like color change and cymophane spinels. Color change spinels are discovered in Srilanka and Umba river of Tanzania.

变色尖晶石是在斯里兰卡和坦桑尼亚的文巴河流域发现的，自然光下呈石蓝紫色，白炽光下呈紫红色。

The exoplanet's atmosphere condenses out minerals such as enstatite, corundum, spinel, and wollastonite.

这颗系外行星的大气冷凝后产生矿物，如：顽火辉石、刚玉、尖晶石和硅灰石。

The oxides with spinel and peroskite structure are the key active components for phenol hydroxylation, and higher contents of them have the higher reaction activity.

形成的尖晶石或钙钛矿结构为苯酚羟基化反应的活性相，具有良好晶态的复合氧化物催化剂的反应活性较高。

For example, if you like blue, there are sapphires, blue topaz, iolite, blue spinel, blue tourmaline, tanzanite and even blue diamonds.

举例来说，如果你喜欢蓝色，还有蓝宝石、蓝黄玉、iolite、蓝色尖晶石、蓝色电气石、Tanzanite甚至蓝色钻石。

The lattice constant of MgAl2O4 increases with the increment of MgO content.

随氧化镁含量的增加，尖晶石的晶格常数逐渐变大。

According to the radius of doping metal ions and lattice parameter of doping samples, it was confirmed that doping metal ions replaced the Mn〓 of spinel LiMn〓O〓.

根据掺杂阳离子的半径和掺杂对尖晶石LiMn〓O〓晶格常数的影响规律确定了掺杂阳离子是进入到原来Mn〓占据的位置。

We have found in chapter 3 that LiMn〓O〓 appeared on the surface of LiMnBO glass particales by long time annealing at glass transition temperature have rather good cycling ability.

我们的实验发现，在玻璃转变温度附近长时间退火后，在LiMnBO玻璃微粒表面层生成的尖晶石LiMn〓O〓具有很好的循环特性，这促使我们开展了在晶态LiMn〓O〓表面包覆玻璃态材料，进行表面修饰的研究。
