石英

Roscopic survey technology uses dynamical tuning velocity gyro to measure the angular speed component of earth rotation; the quartz accelerometer measures the acceleration component of earth, the dip angle, azimuth angle, instrument side angle and some other parameters of well bore are calculated.

陀螺测斜技术以动力调谐速率陀螺测量地球自转角速率分量和石英加速计测量地球加速度分量为基础，经计算得出井筒的倾斜角、方位角、工具面角等参数。

As the heating temperature increases, the content of quartz, anhydrite and portlandite in coal ash decreases in reducing conditions and some new mineral phases are formed.

在还原性气氛下，随着温度的升高，煤灰中的石英、硬石膏、氢氧钙石等结晶矿物含量逐渐减少，生成新的矿物质。

The paragenetic sequence are in the order of calcite-kaolinite, secondary quartz overgrowths-illite-dawsonite and ankerite.

成岩共生序列依次为方解石-自生高岭石、次生加大石英-伊利石-片钠铝石、铁白云石。

For example, the secondary overgrowth quartz, authigenic illite, and authigenic ankerite on the cementation was inhibited by oil emplacement, but pyrite was mainly distributed in oil layer and oil water layer, particularly rich in oil water layer.

由于烃类的侵位，使石英的次生加大、自生铁白云石的生长受到抑制，同时也对自生伊利石生长有抑制作用，黄铁矿由于烃类侵位分布在油层、油水层，尤其在油水层中较为发育。

The dominant cements and authigenic minerals include dawsonite, ankerite, calcite, secondary quartz oergrowths and authigenic clay mineral.

胶结物与自生矿物主要为片钠铝石、铁白云石、方解石、次生加大石英、自生粘土矿物。

The authigenic minerals formed before CO2 charging include multi-stages of calcite assemblages, kaolinite and secondary quartz overgrowths assemblages. While the main cements formed after CO2 charging are dawsonite and ankerite.

CO2注入前形成的自生矿物组合主要为多期方解石组合，高岭石、次生加大石英组合；CO2注入之后形成了片钠铝石和铁白云石组合。

High salinity fluid inclusionscontaining daughter minerals have been found in quartz and ankerite of main mineralizingstages, Taibai and Baguamiao gold deposits of Shaanxi province, located in South Qinling.Both deposits occur in Devonian low-grade metamorphic rocks. Daughter minerals weredetected as pyrite, ankerite, halite and arsenopyrite by SEM/EDS and EPMA.

对赋存于南秦岭泥盆系浅变质碎屑岩中的陕西太白金矿、凤县八卦庙金矿主成矿阶段的石英和含铁白云石中的流体包裹体进行研究，发现局部富含高盐度、含子矿物的流体包裹体，通过光学显微镜、电子探针、扫描电镜/能谱发现子矿物主要为黄铁矿、铁白云石、石盐、毒砂及一些成分复杂的子矿物。

The paragenetic sequence of outcrop sandstones may induce to ealy compaction diagenetic facies、carbonate cementation diagenetic facies and feldspar dissolving diagenetic facies, the diagenetic facies of core sandstones are ealy compaction diagenetic facies、ankerite diagenetic facies、authigenetic quarze and kaolinite filling diagenetic facies.

露头砂岩的成岩组合可归纳为早期压实成岩相、碳酸盐胶结成岩相和长石溶解成岩相，岩芯砂岩成岩相为早期压实成岩相、铁白云石胶结成岩相、自生石英与高岭石充填成岩相。

The main paragenetic minerales are: uranophane, uranium blacks, autunite, meta-torbernite, microquartz, quartz, ankerite, calcite, fluorite, hydromica, pyrite, galena, sphalerite, and chalcopyrite.

矿化作用共可分为八个阶段，同位素研究结果表明，矿床中的铀主要来自岩浆溶液，部分轴来自围岩——侏罗系长石石英砂岩。沥青铀矿的同位素年龄为108—109百万年。

As the temperature increases, content of quartz, anhydrite, and hematite in coal ash decrease in reducing conditions and some new mineral phases are formed during heating process. The content of mullite formed in the heating process is the mayor reason of high melting temperature of the ash. Anorthite at high temperature lowers the ash fusion temperature.

随着温度的升高，煤灰中石英、硬石膏、赤铁矿等结晶矿物含量逐渐减少，生成新的矿物质，莫来石的生成是导致淮南煤灰熔点高的主要原因，钙长石起到降低灰熔点的作用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
