石英的

Once the gold-bearing rocks were brought to the surface, the rocks were crushed, and the gold was separated out, or leached out, typically by using arsenic or mercury (another source of environmental contamination).

这主要通过顺着含有金子的石英的纹路进行挖掘和爆破，一旦这些含有金子的矿石裸露出来，它们就会被碾碎，流水冲刷之下，金子就会被分离出来，也有人利用砷和水银(这是环境污染的另一来源)将金子过滤出来。

Of rocks consisting of porphyry or containing large crystals in a fine groundmass of minerals.

由斑岩组成的，或在一团光滑的矿石中含有相对量较大的石英的。

Relating to or containing a group of light-colored silicate minerals that occur in igneous rocks .

由斑岩组成的，或在一团光滑的矿石中含有相对量较大的石英的。

Crystals of pure quartz, usually called rock crystal, are coarseness, colorless, and transparent.

参考译文：纯净石英的结晶，通常称为岩石水晶，是粗糙的，无色的，透明的。

Adding fused MnO2-CaF2 Mineralizer into fine silicon powder can change its cryst al structure and improve the amount of tridymite,thus can improve the kiln furni ture's high temperature properties and prolong its lifetime.

MnO2-CaF2混合矿化剂能改善硅微粉析晶结构，增加磷石英的含量，从而改善窑具的高温性能，延长使用寿命；采用XRD法测定析晶结构，并测定窑具的抗折强度、抗折强度保持率、气孔率、吸水率等各项性能指标，综合分析得出MnO2-CaF2混合矿化剂的最佳加入量为2%。

Formation of augen fabrics is decided by the ductile deference between the porphyroblast and matrix in deformation rock.

长石眼球构造的形成主要是由长石与石英的韧性差决定的，塑性变形首先从斑晶的周围部分开始，逐渐向斑晶发展，脆性残斑核不断减小，这与剪切带内糜棱岩化强度分带相一致。

Crystals of pure quartz, usually called rock crystal, are coarseness, colorless, and transparent.

答案：D分析及考点：平行对称结构，词性不对称，所以coarseness名词应改成coarse参考译文：纯净石英的结晶，通常称为岩石水晶，是粗糙的，无色的，透明的。

It′s easy to control the thickness of the spacer of the device when employing the fused quartz as the material of the spacer,so the thin film interleaver can satisfiedly meet the demand of the narrow wavelength gap for the DWDM system.

采用间隔层为熔融石英的薄膜法布里-珀罗滤光片作为基本结构的光学梳状滤波器可以比较容易地控制各腔的厚度，因而能精确地达到波分复用系统中波长间隔非常窄的要求。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
