镁的

It mainly reaches the following achievements:1 Through the research of petrology and geochemistry, it is found that dunite takes over 85 percent in ultramafic intrusion, which largely contains Mg(39.66%-47.20%) and Fe(733%-11.17%). The containing of Mn. K. Na, P and Ti is less than 0.1 percent respectively. So it has typical characteristic of leaving of mantle rocks, while it doesnt have partly characteristic of melting.

The results showed that the technology of smelting magnesium with Pidgeon process in China is leading to a large amount of materials input. While China is contributing to up to 70 percent of market share in the international magnesium output, 80 percent of the ecological pressures are left at home, creating severe impact on the environment in China.

物质流分析结果表明，我国原镁生产阶段的物质投入量巨大，在为世界镁产量提供70%份额的同时，却将80%以上的生态压力留在了国内，对我国的环境造成了严重的冲击。

Fertilizing date presented obvious effects on root growth and distribution. Fertilization after watering was more primitive to the root in up-soil layers than before watering. Fertilization of Ca-Mg was positive to the increase of root in 5-15cm soil layer, but negative to that in the surface layer. Both fertilization date and Ca-Mg fertilizer affected root vigor obviously.

施肥时期对根系也具有明显的影响，与灌水前施肥相比，灌水后施肥有利于促进根系在上层土壤中的生长和分布；钙镁肥的施用能增加5~15cm土层根重，但对表层根的生长不利，施肥时期和钙镁肥施用与否对根系活力的影响也较大。

The results of weight-loss tests of many magnesium alloys containing different concentration Al and Rare earth elements showed that the effect by only adding aluminum to improve the corrosion resistance of magnesium alloys in sodium chloride solution was unstable.

不同铝和稀土元素含量的镁合金的失重实验结果发现铝元素对于改善镁合金在NaCl溶液中耐腐蚀性能的作用是不稳定的。

It includes the following steps: extract trivalent iron ion and divalent iron ion in water phase through organic extractant, get predecessor of; absterge it with secondary distilled water for2-3 times and get pure load metal predecessor of organic phase; mix organic phase of Mg2 and Fe3 with mol rate of 1:2 and introduce them into autoclave, add distilled water according to the rate of 3:1 or 4:1 of organic phase and water phase and airproof it, and then mix it fiercely, stripping with hydrothermal method at temperature between 200 degree C and 300 degree C and make them react for 2.5 hours; cool it to the room temperature under natural condition, separate liquid and centrifugalize it, absterge it with absolute alcohol for 2-3 times and dry it at temperature of 50 degree C for 30-180 minutes, then get product of magnesium ferrite.

包括如下步骤：通过有机萃取剂来萃取水相中的三价铁离子和二价镁离子，制得有机相前驱物；用二次蒸馏水洗涤2-3次，获得纯净的负载金属有机相前驱物；按照Mg 2 和Fe 3 摩尔比1∶2将有机相混合均匀后引入高压釜中，按照有机相与水相的比例为3∶1或4∶1加入蒸馏水，密封后，对溶液进行强力搅拌，水热反萃的温度在200-300℃之间反应2.5小时；自然冷却至室温，分液，离心分离，用无水乙醇洗涤2-3次，在50℃下干燥30-180分钟，得铁酸镁产品。

Advance in the study of Neoproterzoic mafic-ultramafic rocks in the western margin of the Yangtze craton has been reviewed in this paper. These rocks consists of 0.95—0.90 Ga orogenic rocks and 0.86-0.74Ga anorogenic rocks, which reflect Neoproterozoic tectonic evolution from arc to intra-continental rift in the area.

RESULTS:In the Chenxiang Lubailu table,the identification of bismuthic salt positive result with dilute nitric acid instead of hydrochloric acid and the white precepitation formed in identification of magnesian was bismuth hydroxide sediments,it was easy and accurate to identify bismuthic salt by adding ascorbic acid.

结果：该片中的铋盐碘化钾鉴别反应，用稀硝酸代替盐酸做溶剂，呈正反应；镁盐氯化铵-磷酸氢二钠鉴别反应，加氨试液后，析出的白色沉淀不是Mg2，而是Bi3，该沉淀在氯化铵试液中不溶，干扰镁盐鉴别；铋盐含量测定项，用加抗坏血酸掩蔽剂的方法，排除Fe3+的干扰，使终点颜色稳定，易于准确判断。

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。
