Imitations of gold, silver or electrum

金，银或金银仿制品

It is common that minerals of electrum and native gold present in the gold deposits in Eastern Shandong contain Sb, Se and Hg; while those in Western Shandong contain Bi,...

这些矿物的颜色、比重、硬度、反射率以及晶胞参数等物理特征与金银含量比变化有明显关系。

So anatase titanium oxide can separate electrum and cavity more effectively. At the same time, anatase has better photoactivity than rutile. Therefore it is significant to research how to prepare stable anatase titanium oxide film. On the other hand, titanium oxide absorbs ultraviolet light strongly (absorption edge is at 380nm) but visible light weakly.

在光催化方面TiO_2的激发必须在高能量的紫外光下才能进行，而到达地面的太阳能中只有3-4%的紫外光，人工紫外光又价格昂贵，所以将光激发红移到可见光区，可降低成本、节省能源。

"The first Western coinage, possibly begun by King Gyges of Lydia (7th century BC), consisted of irregular ingots of electrum bearing his stamp as a guarantee of negotiability at a predetermined value."

西方造币最早可能由公元前7世纪里底亚盖吉兹国王开始的，货币由不规则的银金矿锭组成，其上有国王的印记，以保证它按事先规定好的价值流动。

"The first Western coinage, possibly begun by King Gyges of Lydia (7th century BC), consisted of irregular ingots of electrum bearing his stamp as a guarantee of negotiability at a predetermine d value."

西方造币最早可能由公元前7世纪里底亚盖吉兹国王开始的，货币由不规则的银金矿锭组成，其上有国王的印记，以保证它按事先规定好的价值流动。

Taking Au-Ag intergrowth compounds as an example this paper has reached the following conclusions. In the Au-Ag compounds of differem types of gold deposits as sequemially replaces Au, making up a continuous isomorphous series. The content of Au and Ag in native gold forms a regular pattern. The development of native gold and that of electrum have something to do with different types of gold deposits respectively. Abundances of trace elements in Au-Ag minerals are controlled by geological settings and geochemical fields. The above study provides new geological information and a new method for the study and exploration of gold deposits.

本文以金银互化物的研究为例，讨论了在不同在因类型矿床中，金－银构成一个连续的类质同象系列，且变化是有规律可循，其微量元素的含量与该矿床成矿地质环境和相应的地球化学场有关，从而为找矿提供了新的地质信息，拓宽了寻找同类伴生元素矿床或发现新类型矿床的途径。

In the ores there exist a low-temperature mineral assemblage of arsenopyrite, stibnite, jamesonite, silver fahlerz,berthierite, and electrum, which is consistent with the measurement result of the ore temperature. It can be seen that one the outstanding features of the Sawaya''erdun gold deposit is low-temperature metallogenesis.

在矿床中发现的一套由针状毒砂-辉锑矿-脆硫锑铅矿-银黝铜矿-辉锑铁矿-自然银-单斜磁黄铁矿等组成的低温矿物组合，与成矿温度的测定结果(主阶段100-230℃)相当吻合，显示出该矿床的成矿特殊性-低温成矿作用。

There are 2-3 group metallogenic temperatures, highest 355-395℃ lowest 135-155℃. Gold occurs in nature gold, electrum and isomorph.

金星独立矿物自然金、银金矿和类质同象存在。

The datum that 40 lumbars had been scanned by Electrum Beam CT were converted into the soft Mimics 8.1 and reconstructed 3D lumbar image. The distance from the entrance point to pedicle axis and the inserting safe range of transverse section angle were measured.

在40例腰椎CT三维重建图像上应用人字嵴顶点法、Magerl法及Roy-Camille法模拟置钉，测量进钉点至椎弓根轴线的距离及置钉水平面角的安全范围，比较三种方法在腰椎各节段安全性的差异。

Located in the eastern side of the large-scale silver deposit in Yindonggou, the Yindongyan electrum deposit is nearly the same as the silverr deposit in metallogenetic geological background and ore-controlling structures.

摘要银洞岩银金矿床位于竹山银洞沟大型银矿东侧，且二者在成矿地质背景、矿构造条件等诸方面极为相似。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
