The performance of spinel ferrite is found to be related to their stoichiometric compositions and microstructures,which are predestined by the preparation processes.

尖晶石铁氧体的性质与其化学配比和微结构有着密切的联系，而这些又与其制备过程密不可分。

So the spectacular "rubies" owned by Tamerlane, the Mongol conqueror, Henry VIII of England, and Peter the Great of Russia are all spinels.

Aenigmatite , like sodium amphiboles and sodium pyroxenes, is also a kind of alk.

钠铁非石是一种三斜晶系的富钛、铁、铀的单链非辉石类硅酸盐矿物，通常和钠质辉石共生。

Ironically red spinels, often referred to in ancient texts as balas rubies , are actually more rare than ruby but, unlike ruby, they can sometimes be found in very large sizes.

讽刺的红色尖晶石，通常称为远古课文balas红宝石、更为难得的是红宝石而不是像红宝石，他们有时会发现大小非常大。

Balas , or Balascia , refers to Badakshan in northern Afghanistan, an active gem-producing region during the Middle Ages whose big and beautiful red to pink spinels were considered the best rubies of their time.

balas，或者balascia，指在阿富汗北部巴达赫尚、积极宝石生产区在中世纪的美丽海滩，以大粉红尖晶石当做最好红宝石的时间。

With the increase of calcination temperature, the interaction between cobalt phase and support becomes stronger, and Co3O4 gradually changes to CoxAl(8/3-2x/3)O4 spinel.

随着焙烧温度提高，活性组分与载体的相互作用加强， Co3O4相逐步向CoxAl(8/3-2x/3)O4尖晶石相转化，这可能是样品氧化活性下降和选择还原活性升高的主要原因。

In other words, the colour shift is not like alexandrite, colour change sapphire, spinel, or garnets where the effect is immediate.

换句话说，就是把不喜欢的颜色宝石、蓝宝石的颜色变化，尖晶石、如果是即时生效或石榴石。

XRD and SEM were used to analyze the phrases and microcosmic structure of the hercynite in different temperatures in N2 atmosphere, and the effects of sintering temperature and Fe content on the sintering performance were also studied.

通过XRD和SEM分析在N2气氛中不同热处理温度制备铁铝尖晶石材料的相组成及其显微结构，研究了烧结温度和铁加入量对试样烧结性能的影响。

Pair of sample that add Al and Si fall in two kinds of temperature, magnesian olivine (Mg2SiO4) and pointed spar (MgAl2O4) shows similar action.

在两种温度下对添加Al和Si的试样，镁橄榄石(Mg2SiO4)和尖晶石(MgAl2O4)显示出相似的功能。

With a strong technical research and develop team, our company has developed four generations of microlite product during five years and is recognized by the end market.

我公司拥有技术力量雄厚的研发队伍，历经五年，共开发了四代微晶石产品，并得到了终端市场的肯定。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
