AndLeptochlorite in Goutouling mine, chamoisite in Bailashui mine and brunsvigite inWuchangping and Shanmenkou mines are concluded by Electron-probe analysis .The content ofFe is richer in this field, which demonstrates forming environment is relatively acid andFe/ of different stages of mineralization is regular.

对其电子探针分析表明，绿泥石的种类分别是狗头岭矿区的鳞绿泥石、白腊水矿区的鲕绿泥石、山门口和白腊水屋场坪矿区的铁镁绿泥石和辉绿泥石，说明芙蓉锡矿田中绿泥石都为富含铁的绿泥石，铁取代镁，铁含量增大，表征其形成于相对酸性环境，且不同成矿期Fe/有一定规律性。

The thermal shock resistance of the brick is expected to improve as a result of bigger bulk density, lower thermal expansion coefficient, phase transformation of fused MgO-ZrO2 eutectic powder, formation of magnesiaalumina spinel and forsterite.

材料性能的变化主要与电熔MgO-ZrO2共晶砂的体积密度大、热膨胀系数小、氧化锆的相变、镁铝尖晶石和镁橄榄石等物相的生成相关。

Hundreds of mafic volcanoes scattered through the Three Sisters region are part of a much longer zone along the High Cascades of Oregon in which birth of new mafic volcanoes is possible.

散布在三姐妹山区的数百座铁镁质火山是沿着俄勒冈高台的更大区域的一部分，在那里，可能会产生新的铁镁质火山。

Recent studies suggest that the Mesozoic granitoids and the contemporary mafic and ultra-mafic rocks from the North China block and Dabie-Sulu orogenic belt have the similar Sr, Nd isotopic characteristics, and many of the granitoids and volcanic rocks exhibit some features of adakites.

近年来的研究证实，华北地台和大别—苏鲁造山带的中生代花岗岩与同时代的镁铁质超镁铁质岩有类似的Sr、Nd同位素特点，许多花岗岩和火山岩还具有类似埃达克岩的地球化学性质。

Petrographic and petrologic characters of granitoids and its mafic microgranular enclaves in middle Gangdis〓 belt show that both of them are of magma origin, coexisting marie and felsic magmas, which may be represented by microgranular enclaves and granitoids respeetely, favour magma mixing model.

冈底斯带中段花岗岩及其中铁镁质微粒包体的岩相学、岩石学特征表明花岗岩及其中的包体都是岩浆成因的，两者所代表的长英质、镁铁质岩浆表现为岩浆混合关系。

The authors have summarized relevant data studied by overseas scientists and suggested the definition of chalky texture formation as "Chalky texture formation refers to that magnesium calcite and aragonite are transformed into the framework of micrite and microspar of low-magnesium calcite via neomorphism, and result in and maintain intercrystalline pore and throat networks in it; enhanced chalky texture formation refers to that the micrite and microspar are successively subjected to dissolution and leaching, so that the secondary network of solution voids is formed".

综合各国学者的有关研究资料，建议将白垩状结构化定义为：&碳酸盐沉积物和碳酸盐岩中的镁方解石和文石在不同成岩阶段通过新生变形而转变成低镁方解石微晶和微亮晶格架，并在其中产生和保存晶间孔喉网络的作用；强化白垩状结构化是指微晶和微亮晶格架受到进一步溶蚀和淋滤，从而形成次生溶蚀孔隙网络的作用&。

The dust around PG 2112+059 contains large quantities of rock-forming minerals, including crystalline forms of silica, a form of aluminium oxide called corundum (better known on Earth as the principal ingredient of rubies and sapphires) and a form of magnesium oxide called periclase.

PG 2112+059类星体周围的尘埃含有大量形成岩石的矿物，包括硅晶石，被称作刚玉的铝氧化物（更为通俗易懂的说法是红宝石和蓝宝石的主要成分），以及镁氧化物——方镁石。

The absorption bands observed for Pb-pheophytin a at 462nm and 673nm , while for Pb-pheophytin b at 480nm and 662nm . Compared with pheophytin a and pheophytin b, all these bands red shifted more or less. Among the reported metallochlorophylls, the degree of red shift of Pb-pheophytin in Soret band was the largest by 54nm and 44nm for Pb-pheophytin a and Pb-pheophytin b, respectively.

实验表明：对铅叶绿素a和b系列来说，它们在Soret带、Q带的特征吸收峰分别在462nm，673nm和480nm，662nm；与脱镁叶绿素a，b相比，铅叶绿素a，b在Soret带和Q带吸收峰均有不同程度的红移；与现已报道的金属叶绿素相比，铅叶绿素a，b在Soret带的红移程度最大，分别为54和44nm；铅叶绿素不具有荧光活性，并能猝灭脱镁叶绿素的荧光。

Our experience confirms the complete resolution of hypomagnesaemia within 2 months of stopping, and the feasibility of rechallenge with cetuximab when magnesium concentrations return to normal.

我们的试验证明了使低镁血症终止两个月以内是完全可以的，并且当镁浓度回到正常水平的时候，利用西妥昔单抗二次给药也是可行的。

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。
