尖晶石

The results show that the dissolution rate of various minerals in the slag decrease in the following order of spinel, diopside and perovskite.

结果表明：高炉渣中镁铝尖晶石最先浸出，其次是攀钛透辉石和富钛透辉石，钙钛矿的浸出速度最慢。

The meta-peridotite consists of dunite, harzburgite, lherzolite, feldspar-bearing lherzolite and garnet-bearing lherzolite and contains residual spinel with Cr#s [100*Cr/] of 30-57 and Mg#s [100*Mg/(Mg+Fe2+)] of 50-75, indicating an Al- and Mg-rich series.

变质橄榄岩主要为纯橄岩、方辉橄榄岩、二辉橄榄岩、含长二辉橄榄岩和含石榴石二辉橄榄岩，岩石中残余尖晶石的Cr'值=100×Cr/(Cr+Al为30～57，Mg'值=100×Mg/(Mg+Fe2+为50～75，指示一个富Al和Mg成分系列。

Rock types of lithospheric mantle beneath Eastern-North China platform include harzburgite, garnet and/or chromite lherzolite, dunite, wehrlite, pyroxenite, phlogipitite, eclogite, and metasomatic rocks.

华北地台东部古老地幔岩石类型包括方辉橄榄岩、石榴石/铬尖晶石二辉橄榄岩、纯橄榄岩、异剥橄榄岩、各种类型的金云母岩和辉石岩、榴辉岩及交代岩石。

The spinel is emerging today from the shadows to find its own place in the light.

正在形成的尖晶石今天从阴影中找到自己的位置，在光线。

On the insertion of Li with low current density, the crystal structure is keeping original spinel; while with higher current desity or by thermal activation, owing to violent movement of Li~+ ions, part of crystal structure transforms into rock type similar to face—centered cubic structure of ferrous oxide.

结果表明，以较小电流密度嵌锂时，晶体结构保持原来的尖晶石型；当以较大电流密度嵌锂或热激活时，由于Li~+的运动加剧，部分晶体结构转变为类似于氧化亚铁的面心立方结构。

The effect of magnetic field on no-spinel structure ferrite was also investigated.

也研究了磁场对其它非尖晶石结构铁氧体的微结构的影响。

Chapter 2 describes the crystalline structure and magnetic properties of spinel ferrite.

第二章，介绍了尖晶石结构铁氧体的结构及磁性。

This invention relates to method for preparing spinel-type ferrite at mild condition.

本发明提供了一种温和条件下制备尖晶石型铁氧体的方法。

Some studies showed that: if the hot side of the firebrick has a stable coating, it can effectively increase the life span of the firebrick. Luckily, hercynite has good property of adhering coating.

有研究表明：若能在耐火砖的热面形成稳定的窑皮，就能有效地提高耐火砖的使用寿命；而铁铝尖晶石又有很好的挂窑皮能力。

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。
