So we can inverse telluric current structure of medium according to the response, that is, the resistivity and distribution of underground rock and mineral.

电法勘探的理论基础是不同岩石矿物的电阻率不同，不同地电结构的场响应不同，因此我们可以由观测的场响应反演出介质的地电结构，即地下岩石矿物的电阻率及分布。

The theoretical foundation of electrical prospecting is that the resistivity of different rocks and minerals are different, and different fields have different responses to telluric current structure. So we can inverse telluric current structure of medium according to the response, that is, the resistivity and distribution of underground rock and mineral.

电法勘探的理论基础是不同岩石矿物的电阻率不同，不同地电结构的场响应不同，因此我们可以由观测的场响应反演出介质的地电结构，即地下岩石矿物的电阻率及分布。

For in 14 other time periods upon other dimensions going back billions and billions of years, earth was a terrarium that sustained interesting plants, animals and minerals not found anywhere else in creation.

因为追溯到亿万年前、在其他密度的另外14个时期中，地球曾是一个维系有趣植物、动物和矿物的生物培育器，这些动植物、矿物是在造物的任何其他地方都不能找到的。

Such derivatives are prepared by reacting a kaolin group mineral with a reagent, such as, an alkali metal halide or an ammonium halide which converts the majority of the octahedrally coordinated aluminum in the kaolin group mineral to tetrahedrally coordinated aluminum.

这种衍生物是通过将高岭族矿物与一种试剂，例如一种碱金属卤化物或一种卤化铵进行反应，从而将高岭族矿物中的大部分六配位铝转化为四配位铝而制备的。

Moreover, copper and silver in silver sulphosalts of the tetrahedrite group show negative correlation, and their high or low silver content bears no relation to at atomic proportion and Sb/ ratio.

这些矿床的矿石矿物组合和银硫盐矿物多在主要硫化物之后晶出的产状特征及其化学成分的近似性，反映出成矿溶液成分及成矿作用演化的相似性。

The gold ores have mineral association of pyrite, tetrahedrite, chalcopyrite, galena, sphalerite and Au-Ag mineral series, and element association of Au-Cu-Ag-Pb-As-Sb-Bi, which show certain vertical zonal regularity.

矿石矿物组合为黄铁矿、黝铜矿、黄铜矿、方铅矿、闪锌矿和Au-Ag系列矿物，具Au-Cu-Ag-Pb-As-Sb-Bi的元素组合，并显示一定的垂直分带规律。其成因类型为地下热卤水型。

Quartz thermoluminescence method is one of them.

利用石英矿物的375℃热释光峰的等温衰退特性，探讨其应用于石英矿物受热历史的实验研究，就是这样一种尝试。

This study shows thermomagnetic analyses, petrographic measurements and soil chemistry methods can be combined to obtain a better understanding of the sequence of magnetic mineral alterations during thermal treatment and of the pedogenic mechanism responsible for the susceptibility enhancement.

本文以热磁分析手段为主，结合土壤化学和X射线衍射等非磁学方法，系统研究了黄土高原全新世风成沉积在热处理过程中磁化率的变化特征和磁性矿物的转化序列，讨论了主要磁性矿物的成因，并探讨了特定温度范围内磁化率变化特征的古气候意义。

Ages of such minerals as muscovite, quartz, tourmaline and beryl from the Lushui tungsten-tin deposit in western Yunnan were determined by 40Ar-39Ar method. The trace K minerals all form saddle-shaped age spectra of excess 40Ar.

中文摘要：采用40Ar-39Ar计时方法测定滇西泸水钨锡矿床的白云母、石英、电气石和绿柱石等矿物的年龄，其中微量K矿物均形成含过剩40Ar的马鞍形年龄谱。

It is found that,through sliding zone soil mineral component and water-soil interaction analysis,the principle reason of landslide is that coal measure strata turves soil contains certain proportional hydrophilic mineral ,and its mechanical index will fall greatly after water-soil interaction.

以京珠高速粤境北段k18+170~k18+225滑坡为例，研究了煤系地层滑坡机理，通过对滑动带土的矿物组成及其物理力学性质分析，发现该类边坡滑坡的主要原因是煤系地层中的泥炭土含有一定比例的亲水矿物，在水的作用下力学性质发生大幅度降低。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
