However, the spinel LiMn〓O〓 and olivine LiFePO〓 are very hopeful material with low price and few toxic and higher specific capacity, etc.

本文从降低锂离子电池的生产成本和提高材料的稳定性出发，主要研究尖晶石LiMn〓O〓和橄榄石LiFePO〓的合成制备方法，以及掺杂提高电池材料的稳定性等问题。

This suggests that the secondary orthopyroxene formed at the expense of olivine and clinopyroxene during the metasomatism by an evolved Tirich melt.

与含石榴石橄榄岩中的斜方辉石相比，这种次生的斜方辉石以高TiO2、中等含量的Al2O3以及低Mg＃为特征，表明它是在一种高度分异演化的富Ti熔体交代作用下通过消耗橄榄石和单斜辉石方式形成的。

So, we suggest people to employ these phases to detect metastable olivine in subduction zones.

因此，可以尝试用这组震相来探测俯冲带亚稳态橄榄石的存在状态。

Factors including pH, concentrations of heavy metals, dosages of minerals, ionic strength and temperature were studied and the results indicated that nepheline syenite and olivine had significantly higher capacity of absorbing heavy metal ions than glacimarine clay since they possessed stronger neutralization ability to acidic solution.

考察的因素包括溶液pH值、重金属离子浓度、矿物用量、离子强度、温度等，并得出结论，霞石正长岩和橄榄石吸附重金属离子的能力明显强于冰海粘土。通过理论分析表明，导致这一现象的原因为霞石正长岩和橄榄石对酸性溶液具有更强的中和能力。

On the basis of the study on the petrology, Trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. One is the basanite-alkaline basalt-Olivine tholeiite magma series, which are generated by partial melting from spinel Iherzolite; the other is nephelinite magma-alkaline picritic basalt magma, which are generated by partial melting of the garnet Iherzolite.

岩石化学、微量元素、同位素地球化学证据都表明，华北、华南地区的火山岩根据源岩和局部熔融程度的不同，可以分为两个原生岩浆系列：一个是源岩为尖晶石二辉橄榄岩，随着局部熔融程度的增加，形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆；另一个是源岩为石榴石二辉橄榄岩，随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。

Based on this modification and the experimental data, we first evaluate the nucleation of olivine.

在此基础上，根据已有的实验资料，首次对橄榄石相变的形核率进行了估计。
