尖晶石

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。

The crystallographic parameter and electrochemical performance of the LiyCrxMn2-xO4 are influenced by the amount of lithium and chrome.

实验结果显示，对于尖晶石 Li1.05Cr0.05Mn1.95O4的最佳热合成温度是 750℃，而合成LiyCrxMn2-xO4样品的晶体学参数和电化学性能在很大程度上受锂和铬的含量的影响。

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。

The equilibrium P-T conditions of the spinel lherzolite xenoliths in the study area are: T=913~1045℃, P=13~22kb corresponding to depths of 45~83 km. The P-T conditions suggest that the geothermal gradient of the upper mantle beneath the study area is approximately similar to oceanic geotherm which may be caused by asthenosphere upwelling.

本研究尖晶石二辉橄榄岩之平衡温度大致介於913℃1045℃之间，平衡压力则介於13kb~22kb，深度大约介於 45km~75km 之间，其温压范围大多接近於大洋地区之地温梯度，此相对较高之地温梯度可能与软流圈之上涌有关。

We also report the exsolution texture of Crspinel in orthopyroxene in the studied harzburgite, and suggest that it is the result of a metamorphic reaction induced by the drastic increase of oxygen fugacity during the rapid emplacement of Darbut ophiolite.

方辉橄榄岩中的斜方辉石发育铬尖晶石出溶结构，出溶棒的成分特点表明，该结构是达拉布特蛇绿岩在快速就位过程中环境氧逸度突然升高诱发变质反应的结果。

In technological condition at 1400℃, its main phase was synthetic hercynite.

在工艺条件下，在热处理温度为1400℃时，其产物的主要相为铁铝尖晶石

In technological condition at 1300℃, its main phase was synthetic hercynite.

在工艺条件下，热处理温度为1300℃时，其产物的主要相为铁铝尖晶石。

Just for this purpose, we did the experiment of synthesizing hercynite.

所以本试验就是基于此目的而对铁铝尖晶石的合成进行研究。

This is a development of a new generation of "heavy duty" magnesia brick based on HERCYNITE SPINEL and special burning technology.

该产品是基于铁铝尖晶石和特殊烧结技术而发展的新一代&重型&镁质砖。

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。
