橄榄石

The chemical evolution of the LT1, LT2 (in central Tianshan and Baishan of Gansu), LT4 (in western Tianshan, Jungar and Baishan of Xinjiang) and LT3, HT lavas is controlled by an olivine + clinopyroxene fractionation, but gabbroic fractionation accounts for the chemical variation of the LT4 lavas from eastern Tianshan.

LT1、LT2、LT4（天山西段、新疆北山和准噶尔）和LT3、HT熔岩的化学演化系受控于橄榄石+单斜辉石结晶分离作用；而天山东段的的LT4熔岩的化学变异则是经受了辉长岩质结晶分离作用。

Any of a group of igneous rocks composed mainly of olivine and various pyroxenes and having a granitelike texture.

These processes resulted i n the formation of peculiar dunites in the hyperbasite complexes ,development of low-sulfide horizons and hortonolite dunites in the basite-hyp erbasite layered intrusions (platinum-group metal deposits),and specific proces ses of transmagmatic sulfurization of the iron-rich igneous differentiates (Cu -Ni sulfide and Cu-Zn-Pb sulfide ores).

这些作用导致产在超基性杂岩中的特殊纯橄榄岩、基性超基性层状侵入体中的低硫层和铁镁橄榄石纯橄榄岩的形成，以及富铁火成分异岩的透岩浆硫化作用(Cu-Ni硫化物和Cu-Zn-Pb硫化物矿石)。

The electron microprobe analyses show that there are distinct differences between two types of olivine in the aspects of the FeO/MnO ratio, the species of inclusion minerals, the concentrations of Fe an Ni in kamacite and taenite inclusions.

电子探针成分分析结果表明，两种橄榄石中的 Fe O和 Mn O比值，包体矿物种类，包体铁纹石和镍纹石中 Fe，Ni的含量等，均有较大区别。

Following evidences indicate that lherzolite and garnet pyroxenite xenoliths in basalts are captures of mantle fragments when host magma ascending: crystallizing temperatures and pressures of cpx megacrysts and some phenocrysts in host magmas are greater than equilibrium temperatures and pressures of xenoliths; calculated REE partition pattern of assumed equilibrium melts is not comparable with that of studied host basalt rocks; olivine in xenoliths is not in equilibrium with basalt rocks.

寄主玄武岩的单斜辉石斑晶—熔体平衡温度高于石榴石二辉橄榄岩和石榴石辉石岩包体的平衡温度，单斜辉石巨晶和部分斑晶—熔体平衡压力大于包体平衡压力，寄主碱性玄武岩的稀土配分型式和所计算的与尖晶石二辉橄榄岩包体平衡的熔体的稀土配分型式不同，包体橄榄石与寄主岩浆之间的Fe-Mg交换系数低于0.30，均表明包体与寄主玄武岩浆之间不存在平衡关系，因此，包体是被寄主玄武岩浆捕虏的上地幔碎块。

Pair of sample that add Al and Si fall in two kinds of temperature, magnesian olivine (Mg2SiO4) and pointed spar (MgAl2O4) shows similar action.

在两种温度下对添加Al和Si的试样，镁橄榄石(Mg2SiO4)和尖晶石(MgAl2O4)显示出相似的功能。

An investigation to the microstructure of worn sample of dry vibratable materials for tundish working lining after using 40 hours shows that the materials changes the properties of slag by the chemical filter, increases the viscosity of slag, forms a dense layer at slag/refactories interface, then blocks the more slag penetrate in it. The complex phase formed at the interface, such as magnesiowusite and complex spinel et al, would absorb in more low-melting point minerals, then degrade its melting point and dissolve into slag, which forms low-melting point silicate phase, penetrates into dry vibratable materials along with Monticellite and Merwinite bonding phase by diffusion.

根据使用40小时后的中间包工作层残衬结构分析，其侵蚀机理为：干式料对渗入熔渣产生化学过滤作用，增大熔渣粘度，在干式料/熔渣界面形成致密结构，阻碍熔渣的进一步渗透；随着反应的进行复合矿物中熔剂含量的增多，熔点降低，溶于熔渣形成低熔点的硅酸盐相，并沿着干式料中的钙镁橄榄石和镁蔷薇辉石等结合相向干式料基质中扩散渗透。

The rheological behavior of garnet and omphacite have attracted great attentions in recent years.

橄榄石和石英作为分别代表地幔和地壳流变学状态的典型矿物，近二十年来已经积累了大量的实验和天然变形资料可供对比；石榴子石和辉石的流变学性质近年来也已引起人们的注意和重视。

The ophitic and subophitic textures, elongated apatite crystals, low Al(superscript Ⅵ)/Al(superscript Ⅳ) ratios (0.00-0.28, 0.12 on average) in clinopyroxene, and low Cao content in olivine (0.04%~0.24%, average 0.12%) indicate that the gabbrowas crystallized at a low pressure.

辉长岩所具有的辉绿辉长结构、大量细长针状磷灰石、单斜辉石中较低的Al/Al值（0.00~0.28，平均为0.12）及橄榄石中较低的CaO含量（0.04%~0.24%，平均为0.12%），均体现出浅成侵入岩的特点。

The ophitic and subophitic textures, elongated apatite crystals, low AlⅥ/AlⅣ ratios (0.00 ～0.28, 0.12 on average) in clinopyroxene, and low CaO content in olivine (0.04%～0.24%, average 0.12%) indicate that the gabbro was crystallized at a low pressure.

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.
