金属物质

In the system of surfactant with ethoxyl groups, it is believed that ethoxyl groups can form hydroperoxides, and these hydroperoxides endow the surfactant the ability of reduction.

实际上，在许多体系中，有机试剂具有同时作为还原剂、稳定剂和反应介质的功效，在这些物质的存在下， Ag＋很容易被还原成金属 Ag。

Take some of the recent academic research: computer graphics allow us to predict whether small molecules will fit into or react with larger ones - this could lead to a whole new generation of drugs to control disease; chemists are also studying the use of chemicals to trap the sun's energy and to purify sea water; they are also investigating the possibility of using new ceramic materials to replace metals which can corrode.

以一些近来的学术研究为例，计算机呈像技术使我们能预言是否小的分子能与大分子匹配结合或反应？这可能会导致一种全新的制造控制疾病的药物的技术；化学家们也正在研究利用化学物质来获取太阳能和对海水进行纯化；他们也正在研究用新的陶瓷材料来替代易腐蚀的金属材料的可能性。

Thermodynamic process of direct aluminium extraction from aluminium sub-sulphide, which is unstable and easily decomposed into Al and Al2O3 at a low temperature, was analytically studied. The temperature, at which alumina, FeS and carbon react to form aluminium sub-sulphide in different pressure, was evaluated with "Substance Gibbs' Free Energy Functional Determinant" method.

本文利用铝的低价硫化物在高温下存在，低温下不稳定容易分解得到金属铝的特性，从热力学角度引入"物质吉布斯自由能函数法"讨论在不同压力下，氧化铝、硫化亚铁与还原剂碳的反应生成低价硫化物的条件。

Attention should be paid to the mineralization of some dispersed elements such as Ga, Ge and Tl in Langshan polymetallic mining field. The Wulashan-Daqingshan is the favorable area for prospecting greenstone type gold deposit.

调查结果显示，河套地区土壤主要富集Mg、Ca等碱性物质，西部狼山一带的多金属矿区应重视Ga、Ge、Tl等分散元素矿床的研究，乌拉山到大青山一带是寻找绿岩型金矿的有利地区。

And electricity conduction, malleability, ductility, high light reflectivity , and capacity to form positive ions

金属： 具有高电导率、高热导率以及可塑性、延展性和高反光性的物质，在溶解时可以形成正离子和氢氧化物，其氧化物在遇水时并不产生酸。

The foamy substances cover foam protein, polypeptide, isohumulone, melanoid, metal ions, amylase, alcohol and barm etc.

使啤酒形成泡沫的物质有泡沫蛋白和多肽、异律草酮、类黑素、金属离子、多糖、酒精、二氧化碳及酵母等。

Because the main material composition of most industry product is,the metal is mixed metalloid mineral, because this studies mineral products resource,the zoology package of development has important sense.

由于大多数工业产品的主要物质组成是金属和非金属矿物，因此研究矿产资源开发的生态包袱具有重要意义。

When we use metals , it is important to know how they react with different substances.

当我们使用金属时，知道它们与不同的物质是如何反应的是很重要的。

Speaking in the primordially feminine, somatic language of maternity, a celebratory sense of amplitude and gratitude runs through these delectably plump, formal variations with their particular embellishments: one subtly incised with huge butterflies, another sporting a gold-metal bikini, the third, nakedly milk-white (and in fact partly comprised of literal milk powder in the work's constituent material).

从女性最原始的、身体上的母性语言来说，在这些洋溢着快乐的略显肥胖的身体上，流动着一种满满的幸福和感恩之情。她们各自有着自己的独特装饰：其中一个被精心雕刻上了巨大的蝴蝶，另一个则穿着金属色的比基尼，第三个什么都没有穿，全身上下都是乳白色（事实上，这幅作品的组成物质中，部分是精装的奶粉。

The investigators have also taken measurements of neurotoxic metals and antioxidants in blood, because those could also affect child development.

研究者也测量了血液中会毒害神经的金属毒物与抗氧化剂，因为这些物质也可能影响儿童发育。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
