花斑岩一种细晶的花斑岩，带有不规则交生的石英和长石的基质

In the paper the author has researched the influence of the such main raw materials as quartz and orthoclase, which are used to produce the glazed brick, on the expansion coefficient of the porcelain basement and the bottom enamel and has tested the expansion coefficient of the variety of raw materials, the porcelain basement and the bottom enamel.

本文探讨了生产釉面砖主要原料石英、长石等对素坏和釉底料膨胀系数的影响，并对各原料、素坏和釉底料的膨胀系数进行了测试。

In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

本文重点以老厂矿田中的接触带锡铜矿床和脉状矿床为研究对象，采用化学分析、ICP-MS、X射线粉晶衍射分析、电子探针等测试手段，对本区与成矿相关的基性-超基性火山岩、花岗岩、夕卡岩、电气石-石榴石等进行了系统的地质地球化学研究，研究表明：个旧矿区中三叠纪个旧组地层中的火山岩为钙碱性玄武岩-拉斑玄武岩系列，岩石为辉石-角闪石-长石-绿泥石-金云母组合；本区的花岗岩为过铝质花岗岩，主要与燕山期碰撞造山作用有关，锡多金属成矿与形成时代最晚、分异较好的花岗岩关系密切；本区夕卡岩中的有用共生组份随着夕卡岩类型及其矿物组合的不同具有明显的分带性。

These two ores have contrasting mineral associations: anthothyllite + plagioclase + rutile + magnesiohornblende + alkline fledspar for red ore and anthothyllite + phlogopite + epsode + Rutile for black ore.

根据岩相学观察，认为红色金红石矿中存在如下方向的反应：镁角闪石+碱性长石→直闪石+／-斜长石+／-金云母，斜长石很可能只是过渡相，反应最终将形成直闪石+金云母。

Results of X-ray diffractogram and the photogram of SEMVerified that the crystal lattice of feldspar could be destroyed by the strain NBT,releasing the potassium in the lattice for rice.

当矿物基质速效性钾为75.6mg/kg时接种硅酸盐细菌的钾长石受到NBT菌株破坏的程度最大，其次是速效性钾为104.7mg/kg的营养液组。

Granite consists of 20 or more percent quartz, more alkali feldspar than plagioclase.

花岗岩含20%以上的石英，碱性长石多于斜长石。

Any of a group of abundant rock-forming minerals occurring principally in igneous , plutonic, and some metamorphic rocks, and consisting of silicates of aluminum with potassium, sodium, calcium, and, rarely, barium.

"任何一组由大量岩石形成的矿物，主要存在于火成岩、深成岩以及一些变性的岩石中，含有钾、钠、钙及极少的钠的铝硅酸盐，地球的外层地壳中约百分之六十是长石。"

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
