镁

The planet is probably well supplied with minerals containing combinations of magnesium, iron, silicon and oxygen ferromagnesian silicates , and combinations of iron and sulfur (troilite There may .

火星可能蕴藏了大量的含有镁，铁，硅和氧的化合物以及硫铁化合物的矿物质，可能还有一些游离铁。

Calculation on phase equilibria in the KFMASH and NCKFMASH systems indicates that the phase relations of ferromagnesian minerals are controlled by the KFMASH.

在模拟泥质岩石的KFMASH体系和NCKFMASH体系中的相平衡计算表明，NCKFMASH体系中铁镁矿物的相平衡关系受KFMASH亚体系中矿物相平衡关系的控制，但KFMASH亚体系中固相线位置要比实际的高50-60℃。

Firstly, the process of magnesium sulfate from the sulfuric acid leaching filtrate of serpentine is described.

研究了制备条件对镁盐晶须产品的结构和性质的影响。

In order to find the best processing parameter, we simulate vaccum die casting process with the help of orthogonal experiment for magnesium alloy AZ91D shell part with finite element emulation software.

运用有限元模拟仿真软件对镁合金AZ91D壳形件进行多组正交试验真空压铸过程的数值模拟，找出最佳的压铸工艺参数。

The first metamaterial is described as like a nanoscale fishnet stacked with layers of silver and non-conducting magnesium fluoride.

第一metamaterial被称为纳米鱼网一样堆满了层层银和不导电的氟化镁。

All of the samples were investigated by XRD, TEM, BET methods, and were added into in flexible PVC to test the flame retardancy and mechanical properties.

结果表明，在上述水热方法中，氢氧化钠环境水热与引入晶种水热法制得的氢氧化镁超细粉体比表面积低、极性小、分散性好，改性后添加于软质PVC中得到良好的应用效果，且引入晶种水热法易于工业化生产。

That magnesium lamp of the flash , Not photographed In the camera; Stay in the breasts, the Yan Yuan for many years for the fans dream of.

那镁灯下的一闪，不是拍照，是在摄像；停留于双乳间，为圆粉丝多年的艳梦。

Meanwhile, the released H2 can make up the flotage loss of submarines and can be used for combustion battery of dynamic systems.

本文研究了应用机械合金化制备不同成分的铁-镁合金，并在不同的盐溶液条件下，对合金的电偶腐蚀行为进行了研究。

The replacement of SF6 by refrigerant is under development. For example, R143a by AMC and FK by 3M Co. used as protection gas are both classified as HFC with short atmospheric lifetime and are easily to be decomposed into hydrofluoric acid, carbon monoxide and fluoric carbon monoxide at room temperature.

目前发展中的替代性保护气体以冷媒类为主，如澳洲AMC所采用的R134a及美国3M公司所开发的FK气体，两者都属於氟氢碳化合物，不过其半衰期短，即使在常温下，仍极易分解成氢氟酸、CO、COF2等，其中氢氟酸为有害物质，但因含量很少，且在高温下易与镁液反应，故对人体的为害很小。

The process of preparating potassium fluosilicate from the mother liquor of magnessium fluoride has been studied.

研究了以氟化镁母液为原料制取氟硅酸钾的工艺过程，通过试验获得了最佳工艺条件。

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。
