It often has specks of pyrite which look like gold.

它常常有斑点黄铁矿它看上去就像黄金。

SEM images show that the dolomite take the shape of the spheric aggregations with the diameter of 1~2μm, associated with the pyrite aggregations at the similar size.

对这些含白云石矿物的湖底沉积物所进行的扫描电镜研究发现了其中呈球状、椭球状，大小1~2μm的白云石集合体及其伴生的草莓状黄铁矿的存在。

Gold ore occurs within the spilite tectonccla-stic belt and bears a close relation to altered pyrite.

金矿化产于细碧岩构造破碎带内，与蚀变黄铁矿关系最为密切。

Bacterial and chemical oxidation of gold-bearing pyrite gives rise to not only ferric sulfate and sulfuric acid but also ferrous sulphate and low-valence oxide of sulfur. The potential in the system is too low to dissolve native gold to form Au(SO4)2- Experiments indicate that gold does not dissolve in sulfatic iron solution.

含金黄铁矿在细菌氧化、化学氧化过程中，除生成高铁的硫酸盐和硫酸外，还生成了亚铁的硫酸盐及硫的低价氧化物，体系中的电位较低，距溶解自然金呈Au(SO_4)_2~-所需电位甚远，实验表明，金不溶于硫酸铁溶液中。

Such was the case withthe two specimens which Cyrus Harding had brought back, one of magneticiron, not carbonated, the other a pyrite, also called sulphuret of iron.

赛勒斯·史密斯上次带回来的两种标本就是这样，一种是没有碳化的磁铁矿，另一种是黄铁矿，也叫做硫化铁。

For organic-poor sediments, pyrite was of syngenetic and diagenetic.

对于低有机质样品，黄铁矿由同生和成岩组分组成。

The results showed that bacterium thiobacillus ferrooxidans plays a decisive role in oxidation of pyrite.

试验结果表明，微生物对黄铁矿氧化，产生矿山酸性废水起决定性的作用。

This clearly showed that Thiobacillus ferrooxidans played a very important role in pyrite oxidation.

可见，用磷酸铁膜法抑制黄铁矿氧化在野外矿区微生物作用不可避免的情况下难以取得预期效果。

The utilization of nitrogen and energy sources by Thiobacillus ferrooxidans was investigated,and the removal of sulfur from coal pyrite exposed to the air for different time was studied.

对不同氮源、能源的利用，研究了空气中氧化不同时间的煤系黄铁矿的脱硫情况。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
