sulphide

音標(biāo)發(fā)音

Similarly, in the world of seabed geology, if a sulphide deposit is massive, it is not necessarily big, but formless and rich in metals.
同樣，海底地質(zhì)認(rèn)為，如果硫化物礦床是巨大的，并不需要其體積大，只需其不定型和其金屬含量高。
The author even regrets the removal from the paintbox of rich greens based on arsenic and flame-red vermilion formed from powdered mercuric sulphide.
甚至讓筆者感到遺憾的是含砷的濃綠色和粉狀硫化汞制成的火焰般紅色的朱砂從顏料盒中消失了。
For a start, there is a glut of copper, the metal that probably has to cover the cost of any massive-sulphide mine, leaving gold or some other more valuable metal to provide the profit.
首先，任何大型硫化物礦或許都要靠出售提煉出來的銅來收回開發(fā)成本，這樣一來，出售黃金和其他更加值錢金屬的獲利就能作為利潤。

The bacteria are sprayed on to heaps of sulphide ore, along with some acid.
ECONOMIST: A cleaner and cheaper way of refining ore is to use bacteria
Low doses of hydrogen sulphide, a gas which smells like rotten egg, can safely reduce the metabolism of mice, putting them into a state of suspended animation.
ECONOMIST: Researchers find hydrogen sulphide can lower metabolism

硫化物
Sulphide stress-corrosion cracking is very urgent problem in oil and chenical indus- try,gas division.
由硫化物引起的碳鋼和低合金鋼應(yīng)力腐蝕破裂是當(dāng)前以原油、天然氣和煤為原料的煉油、石油化工、煤氣生產(chǎn)單位最為突出的問題，尤以含硫化氫的液化氣球罐的腐蝕最為嚴(yán)重。

The chemical and toxicological characteristic of heavy metals, which association with the organic matter and sulphide, is different. The two different speciations of heavy metals have different influences on the migration, conversion and toxicity of metals.
重金屬有機(jī)結(jié)合態(tài)與硫化物結(jié)合態(tài)具有不同的化學(xué)特性與毒理特點(diǎn)，這兩類物質(zhì)對重金屬元素的遷移、轉(zhuǎn)化和毒性有著各自不同的影響。
