钛辉石

A mass of pyrolite xenolith (such as peridotite andpyroxenide) and high-pressure mineral megacrysts (such as anorthoclase, augite and kaersutite)are found in cone sheets and BS volcanic rocks.

锥状岩席和BS火山岩包含有大量的上地幔岩石包体和高压矿物巨晶(歪长石、普通辉石和钛闪石)。

The static high-pressure experiments show that enstatite transforms to perovskiteSiO〓 at high pressure, so perovskiteSiO〓 is thought to be one of the main compositions of the lower mantle, but if it could keep the perovskite stucture in the whole lower mantle condition, there are still different opinions.

静高压实验研究表明，高压下顽火辉石将转变为钙钛矿型SiO〓，于是人们将钙钛矿型SiO〓列为下地幔的一种主要候选组分，但对于钙钛矿型SiO〓在下地幔压力(24-136GPa)和温度条件(约2000-5000K)是否保持单一相态的问题，目前尚存在不同意见。

The experiment results show that enstatite is transformed into the perovskite structure under the shock compression whereas the perovskite structure is transformed retrogressively into the single-chain structure during the process of pressure release.

对回收样品进行的X射线衍射分析结果表明：两发顽火辉石回收样品的主相均是单链状结构硅酸盐，而非钙钛矿结构；另外，回收样品中均未观察到氧化物SiO2 和(Mg0.92， Fe0.08)O的XRD特征谱线；两发MgO+SiO2回收样品中均观察到SiO2和镁橄榄石(Mg2SiO4)而没有氧化物MgO。

Pyroxene grains in Ti-bearing clasts contain relatively high Al_2O_3(2.79%)and TiO_2(1.57%).

含钛玻屑中辉石含有较高的Al2O3(2.79%)和TiO2(1.57%)含量。

With the decreasing temperature, the solubility of the other components in sillimanite decreased and most of the dissolved components were exsolved, resulting in the formation of the exsolution texture.

南极拉斯曼丘陵长英质片麻岩中的粗粒夕线石可能有内部出溶现象，出溶形成的矿物有磁铁矿、钛铁矿-赤铁矿和石英出溶矿物条纹，并有少量的斜方辉石。

Aenigmatite , like sodium amphiboles and sodium pyroxenes, is also a kind of alk.

钠铁非石是一种三斜晶系的富钛、铁、铀的单链非辉石类硅酸盐矿物，通常和钠质辉石共生。

In this paper, the distribution of clinopyroxene, orthopyroxene, olivine, plagioclase and ilmenite on lunar surface was mapped based on Hapke radioactive transfer model and linear unmixing of spectra using Clementine UV/VIS/NIR data. The result is compared with the results obtained by previous researchers and Apollo sample analysis, and the problems existing in mineral abundance mapping are analyzed preliminarily.

基于Hapke模型与光谱线性分解的矿物提取方法，利用Clementine UV/VIS/NIR数据提取月表单斜辉石、斜方辉石、橄榄石、斜长石及钛铁矿等5类主要矿物的体积百分含量分布，并基于阿波罗月岩矿物分析数据对提取结果进行评价，对方法和提取结果中存在的问题进行分析，提出了进一步改进的措施。

Cu-Fe-Ni sulfides are disseminated both in the core of titaniferous iron ore and in the diallagite pegmatoid.

Cu-Fe-Ni硫化物星散分布于钛磁铁矿核心部分以及易剥辉石似佛晶岩中。

Heat flows derived from garnet, chromite/chromium-spinel and pyroxene of xenoliths, xenocrysts in Mengyin and Fuxian kimberlites are higher than 40mW/m〓 calculated from the pyroxene inclusions in diamonds, and the range of pressure is 20～40kb (equivalent to 65～130km). Metasomatism (as indicated by yimengite and lindsleyite in Mengyin) is very strong in this depth range. Lherzolite, wehrlite, and diamond-free high-Ca harzburigite around the world are derived from this depth also. The observation suggests that the low-Ca harzburigitic environment for diamond stability had been changed significantly when the kimberlitic magmas erupted. This resulted from fluid interaction with harzburigite. The geotherm of the Cenozoic lithospheric mantle beneath Eastern-North China platform is higher than oceanic one. The temperature from the interior of the Tan-Lu faults is higher than that from apart off the fault.

除金刚石中的辉石温压投点落于40m W/m〓占地温线上外，捕虏体及捕虏晶中石榴石，铬尖晶石及单斜辉石的投点均偏离该地温线，显示较高的地温特点，而且捕虏体及捕虏晶的压力范围多在20-40kb(相当于65-130km)间，该深度范围内地幔的交代作用特别发育，如蒙阴大量发育的沂蒙矿、钛钾铬石等就发育于该深度范围，世界范围内不含金刚石的高钙方辉橄榄岩、二辉橄榄岩、异剥橄榄岩也分布于该区中，一方面表明捕虏体的主要取样位置已不在金刚石稳定区中，另一方面也表明金刚石稳定的橄榄岩环境，在金伯利岩侵位并捕虏他们时已发现了明显的改造，这种改造作用主要是通过长期的熔流体与先存的橄榄岩相互作用的结果。

The original alkalic series of basalic magma evolutes into trachybasalt through crystallization differentiation of olivine and pyroxene, and the trachybasalt is transformed into alkalic rhyolite with remarkable Eu, Sr, Ba, Ti, P nagetive abnormalities through strong crystallization differentiation of plagioclase and also pyroxene Ti Fe oxides and apatite, all together leading to the loss of neutral (SiO 2=57%～63%) andesite and trachyandesite in the volcanic rocks in this area and appearance of bimodal volcanic rock combination feature.

原始碱性系列玄武质岩浆经橄榄石、辉石的结晶分异，向粗面玄武岩演化；粗面玄武岩经斜长石强烈的结晶分离作用，还有辉石、钛铁氧化物和磷灰石的分离结晶作用形成具显著Eu、Sr、Ba、Ti、P负异常的碱性流纹岩，导致本区火山岩缺失中性(SiO2=57%～63%)的安山岩和粗安岩，呈现双峰式火山岩组合的特点。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
