矿物的

We argue that there are literally thousands of different minerals that formed only because life produced an oxygen-rich atmosphere, says Hazen, whose team reports its results today in American Mineralogist.

我们认为，有数以千计的各种矿物只是由于生物产生的富氧大气层而形成，黑曾说，他的团队今天在《美国矿物学家》报告了他们的研究成果。

Pore structure experiment shows that porosity of high volume fine mineral mixture RPC is about 5%, the pore distribution is uniform and the main pore is small. When the cement content of high volume fine mineral mixture RFC is 300 kg/m^3, its sclerotium hydration products is dense packed by irregular equal Ⅲ style C-S-H gels. The gels are fine, dense, and integrate with the aggregate.

孔结构试验表明，大掺量矿物细粉活性粉末混凝土的孔隙率均在5%左右，孔分布情况很均匀，主要以微小的小孔为主；水泥用量为300 kg/立方公尺的大掺量矿物细粉活性粉末混凝土硬化体水化产物主要由不规则等粒子状的Ⅲ型C-S-H凝胶紧密堆积在一起，凝胶精细、致密，且与骨料融为一体。

Moreover, copper and silver in silver sulphosalts of the tetrahedrite group show negative correlation, and their high or low silver content bears no relation to at atomic proportion and Sb/ ratio.

这些矿床的矿石矿物组合和银硫盐矿物多在主要硫化物之后晶出的产状特征及其化学成分的近似性，反映出成矿溶液成分及成矿作用演化的相似性。

According to petrographic facies test, gravel sample mainly consists of quartz, albite, dolomite, and minor biotite; and sand sample is mainly made up of quartz and albite. As an important ASR active mineral, chalcedonite exists in fractures of dolomite and in matrix of cherty limestone. In rapid mortar bar test, expansion of sand, small gravel and middle gravel at 14 day are less than 0.1%, but keep increasing in long term.

岩相法检测显示卵石样品主要由石英、钠长石及白云石和少量云母类矿物组成，砂样品主要由石英、钠长石等矿物组成，重要的碱活性物质玉髓主要出现在白云岩裂隙和硅质灰岩的基质中；&砂浆棒快速法&检测结果显示砂、小石、中石样品14天的膨胀率均不超过0.1％，为非碱－硅酸反应活性骨料，但卵石样品仍具有一定的碱活性，且后期膨胀率一直持续增长。

The product offers a perfect solution for the problem of color durableness of mineral coating and makes mineral coating really coexist with nature, really a revolution of coating industry.

改性后的硅酸钾不但具有更为良好的化合性，同时与各种氧化无机色素能良好相容，彻底解决了矿物涂料的色泽问题，使得矿物涂料真正与自然共存，成为涂装行业的一次革命。

So when choose the stimulated energy the certain at the same time make sure the characteristic frequency of the eradiate photons, both for a mineral is constant.

所以在选定激发能量的同时确定发射光子的特征频率，两者对于一个矿物来说都是固定不变的，因而用它就可以直接获得矿物在不同激发条件下的释光谱图。

Instead of learning minerals by rote memorization of chemical classes, he says, students can use the new scheme created by Hazen to "put them into a large-scale context that clearly shows how they are part of the history of the Earth and universe around us."

他说，学生可以使用黑曾创立的新方案，&把矿物放在大范围的背景下，清楚显示它们如何成为我们周围的地球和宇宙历史的一部分，&以代替化学课中死记硬背学习矿物。

萨亚说。他说，学生可以使用黑曾创立的新方案，&把矿物放在大范围的背景下，清楚显示它们如何成为我们周围的地球和宇宙历史的一部分，&以代替化学课中死记硬背学习矿物。

The iron in the zinc sulphide concentrates mainly comprises marmatite and pyrite.

本文研究出一种可靠的、确定精矿矿物组成的化学分析方法，着重于测定铁在精矿各矿物中的分布，及铁闪锌矿铁含量的变化规律。

Surfaces of mineral grains investigated by the SEM method demonstrate differences in flocculation. Measured polarization curves allowed to reveal unequal electrochemical processes on surfaces of magnetite, hematite, and martite particles. Xray analysis and Mssbauer data also confirmed the changes in compositions of the ores before and after applying of the electrochemical method.

采用扫描电镜技术研究矿物颗粒表面，发现其在絮化作用中的差异；偏极化曲线的测定可以揭示磁铁矿、赤铁矿和假象赤铁矿等矿物表面的不均等电化学过程； X射线分析和穆斯堡尔谱数据亦可确定电化学处理前后矿粉样品成分的变化。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
