尖晶石

These systematic studies can contribute to the study of the applications of NiZn ferrite.Meanwhile,the research methods employed in this thesis can also be applied to other kind of similar ferrites and even other ceramics.

以上系统的工作，对NiZn铁氧体的实际应用具有一定的参考和借鉴价值，同时本论文中的研究方法对其它尖晶石铁氧体的研究也具有一定的指导意义。

For the TN process ladles are lined with dolomite, and for the SL process both fire clay and magnesia brick are suitable.

经钢包喷粉处理，可使钢中S.002～0.005％，P.005%，O.0015％，消除MnS型夹杂，形成不易变形的钙铝尖晶石型夹杂物。

In this research, waste activated alumina and basic magnesium carbonate were used as raw materials to synthesize magnesium aluminate spinel by double step firing process.

本研究利用废活性氧化铝与碱式碳酸镁为主要原料，二步煅烧法制备镁铝尖晶石材料。

Basaltic underplating has deepened the CMB from 32 km to 42 km. The lower crust beneath Hannuoba consists mainly of two-pyroxene granulites, with minor felsic granulites, noritic granulites, spinel pyroxenites and spinel lherzolites.

该地温梯度线表明，华北克拉通北缘的岩石学壳幔边界很可能位于约42km处，与地震莫霍面近于一致。32-35km处的尖晶石二辉橄榄岩层可能反映了古岩石学壳幔边界的位置，玄武质底垫作用造成岩石学壳幔边界的深移。

The cathode is generally one of three materials: a layered oxide, such as lithium cobalt oxide, one based on a polyanion, such as lithium iron phosphate, or a spinel, such as lithium manganese oxide, although materials such as TiS2 were originally used.

阴极通常是以下三类材料：一种层氧化物，例如钴酸锂、一种阴离子聚合物，例如磷酸锂铁，或者是一种尖晶石，例如锰酸锂，象例如二硫化钛之类材料曾经是最初使用的材料。

A dark-colored spinel containing iron.

一种含铁的黑色尖晶石。

Jasper was green or dark green, sometimes shows a black dirty points, including minerals and other impurities such as chromium spinels due.

碧玉呈绿或暗绿色，有时可见黑色脏点，是含杂质如铬尖晶石矿物等所致。

The light-weight magnesite-alumina spinel refractories was synthesized by the way of one step sintering, and the effect of the light magnesia powder and the alumina powder addition on its sinterability was studied.

According to the characteristics of element distribution, the spinel compositional zonings were formed by the chemical equilibrium between the crystals and magma during magma crystallization, not by ion diffusion in the processes of subsolidus equilibrium.

从尖晶石成分分带的元素分布特征判断，其形成不是固溶体相平衡过程中的离子扩散，而可能是化学平衡过程中结晶矿物与熔浆之间化学成分平衡的结果，属于化学平衡导致的成分分带。

The color of the spinels are related to Al,Mg and Cr,Fe contents.

尖晶石的颜色与Al、Mg、Cr、Fe含量有关。

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。
