Both the a-axis and ab-plane dip towards the downstream , the dip angles of the a-axis are low and concentrated, being 7—8°,the ab-plane dips at 7～21°, and the a-axis has more preferred dip of fabrics than the ab-plane; the peak of the grain-size frequency distribution curve of deposits in the Lushan area is in the range of 4 and 5 φ;The quartz sand grains are subangular and have well-developed conchoidal fractures, parallel striatio ns, upturned cleavage flakes,"V"-shaped holes and siliceous deposits.

摘 要：庐山第四纪泥砾沉积物的砾石组构特征表明，砾石岩性与山体基岩基本一致，砾石的等体积球径较小，加权平均砾径较中值砾径大，分选系数大于1，分选性差，φ值相对较小，平均为0.66，F值相对较大，在2左右，F/φ比值介于2.75～4.75，ρ值集中且较小，为22.75%～37.75%，砾石以棱角、次棱角状为主，磨圆较差；a轴和ab面都倾向沟谷下游，a轴倾角集中且较小，为7～8°，ab面倾角为7～21°，a轴较ab面具有更为优势的组构倾向；沉积物粒度频率曲线在4～5Φ范围内表现为峰；石英砂颗粒为次棱角状，贝壳状断口发育，具平行擦痕、上翻解理片、V形坑和硅质沉淀。

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

Granitic rocks mainly consist of quartz, plagioclase and alkaline feldspar and hence have lower densities.

花岗质岩石主要由石英、斜长石和碱性长石组成，并因此具有较低的密度。

The microstructure of an uvarovite sample was analyzed using SEM methods. Tiny quartz and chromite inclusions, calcite filling in microfractures and grossularite that forms a solid solution with uvarovite were discovered in the sample. This demonstrates that the uvarovite of eastern Tibet is of skarn origin. The spectral characteristics of the uvarovite were investigated using UV-VIS absorption spectrometry.

采用扫描电镜观察钙铬榴石样品的显微结构并进行能谱分析，结果表明其内部含有颗粒很小的铬铁矿和石英包裹体，以及裂隙中充填的方解石和与钙铬榴石为类质同象连续关系的钙铝榴石，从而为该钙铬榴石的夕卡岩成因和产状提供了佐证。

Because of detection limitation, the gold particles are not found independently in pyrite, scheelite, quartz, and other minerals. So it is believed that submicroscopic gold can be found in gold-bearing minerals as micro-inclusions or isomorphous atoms.

由于受检测手段所限，在含金黄铁矿、白钨矿、石英等矿物中未发现独立金颗粒，所以寨上金矿次显微金呈微包裹体形式存在于载金矿物中或呈类质同象替代的原子形式存在。

Because of detection limit the gold particles are not found independently in pyrite scheelite quartz and other minerals. So it is believed that submicroscopic gold are occurred in gold-bearing minerals as micro-inclusions or isomorphous atoms.

受检测手段所限在含金黄铁矿、白钨矿、石英等矿物中未发现独立金颗粒，所以我们倾向于寨上金矿次显微金呈微包裹体形式存在于载金矿物中或呈类质同象替代的原子形式存在。

Lipid bilayer membrane containing monomeric bovine cytochrome c oxidase was successfully immobilized in gold quartz crystal microbalance electrodes.

含有单体牛细胞色素c氧化酶的脂质双层膜，被成功地固定在金石英晶体微平衡电极上。
