本次论文的研究目的是描述露头砂岩和岩芯砂岩岩石学特征并判断其岩石类型，比较露头砂岩与岩芯砂岩在自生矿物、成岩作用类型、共生序列、成岩相、成岩阶段以及成岩流体演化方面的异同，为研究区有利储层的研究提供理论前提条件。

Based on the field surveys on a wide scale, the systematic studies were made on soil acid properties, particle fractions, exchangeable performances, saturated base, free feeric properties, clay chemical components, clay mineral types and their properties of genesis.

在大量野外调查的基础上，系统地研究了土壤的酸性特征、颗粒组成、交换性能、盐基饱和度、铁的游离度、粘粒化学组成及粘土矿物类型等发生学性质。

Along with the development of the natural science people deepen the color knowledge gradually, for example, written language description is not contented to the needs in some field, and the need is quantitative analysis. Color index can show the characteristics of color exactly. For adapting the development, the authors use the metal-bearing ore's color index analysis for the first time through reflectance determining and the color-imetry theory, and analyses 4 turquoises' color index in various color. So the color of turquoise is quantitated successfully.

随着自然科学的发展，对颜色的认识不断加深，从定性到定量颜色指数可以准确地描述颜色特征，笔者利用色度学原理，通过反射率测定，首次把金属矿物颜色指数分析方法应用于绿松石，分析了4个不同颜色绿松石的颜色指数，成功地实现了绿松石颜色的定量表示。

Urologists often suggest drinking plenty of water to help flush minerals from the kidneys to prevent stones from forming.

泌尿学医师经常建议患者多饮水，这样有助于冲掉肾脏中的矿物，阻止结石的形成。

In this thesis, I sample fifty-two pottery sherds from the Yusnshan and Zhiwuyuan Culture at the Tianwentai Site, and apply petrographic analyses and X-ray diffraction analyses to learn the mineral components and source of raw materials.
