On the basis of a study and elaboration of data, some important conclusions are presented:(1) ruby deposits in marbles occur in the plutonic metamorphic zones of orogens where deep fault structure is developed;(2) ruby-bearing rocks are calcic crystalline marbles, rather than magnesian marbles;(3) amphiboles in ruby-bearing rocks are not tremolites, but silica-poor, alumina-rich and chrome-bearing calcic amphiboles, such as chrome-bearing magnesio-sadanagaites; and (4) the deposits are genetically of thermodynamical metamorphism type, rather than of pneumatolito-hydrothermal type or skarn type.

目前，对于与此类型矿床找矿相关的若干成因问题的认识，还相当模糊，主要表现在以下几方面：①对此类型矿床的产出构造背景认识不清；②认为含矿岩石为镁质大理岩或镁质夕卡岩；③认为含矿岩石中与红宝石共生的角闪石为透闪石；④认为此类矿床的成因类型为"气成一热液型"或"夕卡岩型"。本文在实际研究(王礼胜，1996)和文献资料整理的基础上，分别对这些问题给予了澄

The total amount of Mg and Fe ions in the equilibrium solution depends on the solubility of resulting double salts. The reaction speed is decided by the speeds of ionization of ammonia salts and brucite together.

平衡溶液中镁、铁离子的总量取决于生成复盐的溶解度，反应的速度是由铵盐电离的速度和水镁石电离的速度共同决定的。

Conclusion］Magnesium alloys showed good biocompatibility to L929 mouse fibroblasts, and had no cacoethic effect to test animals, so the magnesium alloys is possible to be a new type and potential of bone surgery implant materials.

结论］镁合金对L929小鼠成纤维细胞有良好的生物相容性，对植入的动物也未见不良的影响，具有良好的生物安全性。因此可以初步认为镁合金作为一种新型的，有潜力的骨科内置物材料是可行的。

Experimental results revealed that triethanolamine has remarkable effect on arc restraining,which ...

实验结果表明：三乙醇胺可以有效抑制火花放电，增加膜层的厚度，使表面孔隙变小，提高表面光洁度；当三乙醇胺浓度为30g.dm-3时，膜层耐蚀性能最好；在阳极氧化过程中，三乙醇胺化学吸附于镁合金表面，从而改变微弧氧化过程中氧气气泡在镁合金表面的吸附强度和氧气气泡的大小，降低了微弧氧化陶瓷层孔隙率，提高了阳极氧化膜的致密性和耐蚀性。

In order to radically improve the present silicothermic reduction process for magnesium smelting, this paper started with the idea of taking liquid calcium as reductant and studied the feasibility of the new magnesium reduction process deoxidizing by liquid calcium .

This product not only contains the various nutrients in the carrot such as vitamins,β-carotene (converting to vitamin A in vivo), protein, active enzymes, minerals (potassium, sodium, calcium, magnesium, iron and zinc) but also is replenished with concentrated carrot essence and red tomato (containing abundant vitamin A, B, C, potassium, sodium and magnesium), which makes it more nutritious and easier to be absorbed by the body. It is the indispensable natural healthy food for the modern.

胡萝卜素不仅保留了胡萝卜所含有的多种维生素、β-胡萝卜素（在体内可转化为维生素A）、蛋白质、活性酶和矿物质（钾、钠、钙、镁、铁、锌）等营养成分，而且因添加了适量的胡萝卜浓缩素、红番茄（含丰富的维生素A、B、C及矿物质磷、钾、钠、镁等营养成分），使其营养成分更加丰富并且更容易被人体均衡吸收，是现代人不可缺少的健康食品。

The SiO2 content of the dike swarms varies from 50.22% to 61.10% and they are basic-intermediate rock series, mainly basic. The Al2O3 content is generally higher than 15% and they are high aluminum basaltic rocks. The lower magnesium index (Mg#=42.77~62.28) and TiO2 content (0.97~2.41%) illuminate that they suffered magnesium-iron minerals' fractional crystallization and that they did not crystallize from original basaltic magma. The values of Na2O/K2O are all above 1, indicating lower K character. Chemically discriminated, these dike swarms are sub-alkaline rock series.

岩墙群的SiO2含量为50.22~61.10%，属于基性和中基性岩类，以基性为主；它们的A12O3含量普遍高于15%，属高铝玄武岩类；具有较低的镁指数（Mg#=42.77~62.28）及TiO2含量（0.97~2.41%），说明它们经历了镁铁质矿物的结晶分异作用，也指示它们不是由原始玄武岩浆结晶；Na2O/K2O都大于1，显示出低钾的特点；岩石化学判别，岩墙群岩石属亚碱性系列。

Re-sults:it was shown that Nano MgO had excellent germicidal efficacy to the Escherichia coli and Staphylococcus aureus.To such spore as Bacillus subtilis var.niger spore,Nano MgO also produced good germicidal effect.It was proposed that abrasiveness,alka-linity,electrostatic attraction,and oxidizing power of nano MgO all combined to promote these biocidal properties.

结果： ①纳米氧化镁能有效杀灭大肠杆菌，对枯草杆菌黑色变种芽孢也有显著的杀灭效果；②纳米氧化镁对金黄色葡萄球菌和枯草杆菌黑色变种芽孢有很好的抑菌作用；③纳米氧化物的磨蚀性、碱性、氧化性以及对微生物的静电吸附使它具有抑菌和杀菌作用。

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.
