The deep origin of Kangjinla podiform chromitite is suggested by: that for the Kangjinla chromitite and the mantle peridotite rocks, the compositions of the chrome spinel, olivine and clinopyroxene are rather different, which indicates that the chrome spinel in the chromitite is neither the simple concentration of that in the host rocks nor with certain genic relation with mantle peridotite. Though the chromitite might be exotic for host rocks, both of them were carried from deep mantle to the shallow place by mantle plum.

康金拉铬铁矿石与矿体围岩地幔橄榄岩的铬尖晶石、橄榄石和单斜辉石等成分方面明显不同，认为矿石铬尖晶石并非是由副矿物铬尖晶石富集而成，与地幔橄榄岩也不存在成因联系，认为豆荚状铬铁矿床对于近矿围岩地幔橄榄岩而言为外来体，但两者可能均是由地幔深部被地幔柱带到上部。

The performace of material was tested by DSC,XRD,SEM,EIS and charge-discharge cycles . The influences of various synthesized condition , sintering time and the amount of F were studied and correlative technics parameter to improve performance of material were optimized. DSC shows that three endotherimc peaks and one large exothermic peak are observed in the temperature range 150-400℃, which is because of the removal of water,the decomposition of the organic constituents and the formation of spinel. Only the citrate precursor is sintered at least 450℃, the crystallinity of spinel phase could be formed intactly.

通过DSC、XRD、SEM、EIS和充放电循环等手段对材料进行性能测试，比较了不同合成温度、烧结时间和不同掺杂元素量等条件对材料性能的影响，优选出提高材料性能的相关工艺参数， DSC表明，采用溶胶-凝胶-络合法制备的前驱体在150-400℃中有三个小的吸热峰和一个大的放热峰，这是前驱体中的水分、柠酸酸及其盐和醋酸及其盐在蒸发及分解，柠檬酸前驱体至少需在450℃以上才可能形成完整的尖晶石材料。

The upper part of lithospheric mantle in western Liaoning could be composed of the spinel harzbergite and minor spinel lherzolite.

辽西区岩石圈地幔的底部为含有弥漫型角闪石的尖晶石二辉橄榄岩；上地幔顶部为尖晶石方辉橄榄岩和少量尖晶石二辉橄榄岩；莫霍面附近为一岩石学上的过渡层，由一套辉石岩类的堆积体组成。

The spinel-garnet lherzolites locate at the depth about 60 km, right in the transition from spinel lherzolite to garnet lherzolite.

上地幔则以尖晶石二辉橄榄岩为主，在其接近莫霍面的42-45km处存在尖晶石辉石岩层，在55-65km之间则存在石榴子石辉石岩层，尖晶石-石榴子石二辉橄榄岩出现于60km处。

The synthesis of the NiFe〓O〓 spinel matrix material, the utility of grain composition of the spinel ingredients when synthesizing the inert anode, and the synthesis of the inert anode was studied essentially in this thesis.

本文重点研究了镍铁尖晶石原料的合成，合成惰性阳极制品时原料的粒度配比和惰性阳极制品的合成。

The experiment results showed that MnO〓 and TiO〓 could accelerate the sintering reaction of the NiFe〓O〓 spinel, improve the density and the intensity of the spinel ceramic, and drop the sintering temperature as well.

研究结果表明，添加MnO〓和TiO〓可以促进尖晶石陶瓷相的烧结，提高尖晶石的密度和强度，降低烧结温度。

In the course of selecting oxide additives material in the nickel-ferric spinel based inert anode, both the solubility in the cryolite molted salt of oxide additives and the whole thermodynamics action in electrolyte of oxide additives are discussed in this article, thus to have a comparatively reasonable selection of the nickel-ferric spinel based inert anode material.

在选择镍铁尖晶石基惰性阳极材料氧化物添加剂过程中，不仅探讨了氧化物添加剂在冰晶石熔盐中的溶解度，而且还探讨了氧化物添加剂在电解液中的整个热力学行为，从而对镍铁尖晶石基惰性阳极材料做出了较为合理的选择。

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 deep-seated xenoliths entrained by the Cenozoic Hannuoba basalts can be divided into three groups according to their mineral assemblages:Ⅰ Granulites, including felsic granulites, noritic granulites, and dominantly, two-pyroxene granulites,Ⅱ Pyroxenites, including websterites, spinel pyroxenites, and garnet pyroxenites;Ⅲ Peridotites, including spinel lherzolites and spinelgarnet lherzolites.

根据新生代汉诺坝玄武岩中深源岩石捕掳体的矿物组合类型，将其分为主要的三大类：麻粒岩类中包括长英质麻粒岩、苏长质麻粒岩和二辉麻粒岩，辉石岩类包括二辉石岩、尖晶石辉石岩和石榴子石辉石岩，橄榄岩类则包括尖晶石二辉橄榄岩和尖晶石-石榴子石二辉橄榄岩。
