本文以Na2O－Al2O3－SiO2系统为基础，引入晶核剂和复合澄清剂，经高温熔制和两步热处理制备的霞石微晶玻璃，具有较高的抗压和抗折强度。

The paper presents distribution of nepheline syenites and theirtectonic settings, rock assembladges, mineral associations and geochemisical characteristics, discusses the relationship between the minerological characteristics of main minerals and their host rock.

文摘：介绍了中国霞石正长岩的分布、产出的大地构造环境、岩体的岩石组合、岩石的地球化学和造岩矿物组合特征。

This type of separators can be used for magnetic separation of various fine feebly magnetic impurities from non-metallic minerals, especially in beneficiation of feldsper, kaolin, nepheline etc, and the technical economic effect is good.

介绍了CRIMM型双箱往复式永磁高梯度磁选机的工作原理、结构和技术参数，指出该机可用于非金属矿加工中去除微细粒弱磁性杂质，并已在长石、高岭土、霞石等非金属矿选矿中获得应用，技术经济效果均佳。

Using nepheline syenite as a substitute for feldspar,the batch mixtures were prepared on a composition of float gl ass and are melted into glasses.

以霞石正长岩取代长石，按照浮法玻璃的成份制备配合料并熔制玻璃。

Analysis of K and Na in nepheline were curried out with higher precision and repeatability by means of adding fluohydric acid during sample melting to remove SiO2 ,adjusting the ratio of K and Na in the solution to reduce the mutual interference of the two elements, and adding cesium chloride to eliminate ionization interference.

摘要本方法用于测定霞石中的钾、钠，主要通过在溶样时加入氢氟酸除去二氧化矽，调整溶液中钾、钠的含量，消除互相之间的干扰，加入氯化铯消除电离因素的干扰，提高了分析结果的准确性和重现性，使测定结果更接近化学分析值。

When borax is added into mullite, Na+ as the electron acceptor easily enters into the lattice of mullite, causing a transition from mullite to nepheline.

因此，向莫来石中加入助熔剂硼砂时，硼砂中的Na＋作为电子接受体，非常容易进入莫来石的晶格中，促使莫来石转变为霞石，降低了灰熔融温度。

Most importantly, with analyzing the calcined cinder by X-ray powder diffraction and scanning electron microscope, it was clear that at an appropriate calcination temperature, the activated SiO2 and Al2O3 in alkaline coal-cinder would react with the decomposed fused Na2CO3 to form a new neutral matter nepheline（NaAlSiO4）and other amorphous silicate compounds,causing an obvious reduction of the alkali content in coal-cinder.

采用X射线粉晶衍射及扫描电镜对煅烧后的灰渣进行表征，揭示了含碱灰渣煅烧脱碱过程的实质，即在适宜煅烧温度下，含碱灰渣中被活化的主要矿物质SiO2、Al2O3和熔融并分解的Na2CO3（分解为修饰网络氧化物Na2O）等发生化学反应转变为中性物质霞石（NaAlSiO4）及其他无定形复合硅酸盐，从而降低了灰渣中的碱含量。

On the basis of the study on the petrology, Trace element, and isotopic geochemistry, the primary magma of volcanic rocks can be divided into two series according to their originated rocks and degree of partial melting. One is the basanite-alkaline basalt-Olivine tholeiite magma series, which are generated by partial melting from spinel Iherzolite; the other is nephelinite magma-alkaline picritic basalt magma, which are generated by partial melting of the garnet Iherzolite.

岩石化学、微量元素、同位素地球化学证据都表明，华北、华南地区的火山岩根据源岩和局部熔融程度的不同，可以分为两个原生岩浆系列：一个是源岩为尖晶石二辉橄榄岩，随着局部熔融程度的增加，形成的碧玄岩岩浆-碱性玄武岩岩浆-橄榄拉斑玄武岩岩浆；另一个是源岩为石榴石二辉橄榄岩，随着局部熔融程度的增加形成的霞石岩岩浆-碱性苦橄玄武岩系列。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
