The response has been to try to remove sulfide from sewage water.

一直以来，人们都在试图将硫化物从污水中分离出来。

Turns out much of it is from drinking water treatment.

调查结果显示，大部分的硫化物都产生于饮用水的处理。

That process is the source of more than half the resulting sulfates in the sewage.

污水中大部分的硫化物均来自一处理过程。

The crew found that sulphide particles had stuck to the tape head and open-heart surgery was needed.

工作人员发现硫化物的微粒粘在了，现在必须拆机。

Last year, KoBold announced its discovery of a rich deposit of chalcocite, a sulphide of copper, in Zambia.

去年，KoBold宣布在赞比亚发现了丰富的辉铜矿(一种铜的硫化物)矿床。

And if it did, that would change the sulfide into another molecule: sulfate.

如果实如此的话，那将使硫化物变成另一种分子：硫酸盐。

But researchers in Australia asked a different question: where does the original sulfate come from?

然而，澳大利亚研究人员却转化了路：些硫化物来自哪里？

One, the accumulation of the toxic chemical sulfide, created when bacteria decomposes dead plant matter.

第一，有毒化学硫化物的积累，当细菌分解死亡的植物物质时产生。

They found higher concentrations of sulfide in the center samples than on the rings and margins.

他们发现中心样本中的硫化物浓度高于圆环和边缘样本。

In a suede suitcase, the police found some sulfate, sulfide and sulfur.

警方在一个麂皮小提箱里发现了一些硫酸盐、硫化物和硫磺。

Quantum dots are usually made from semiconductor materials, such as graphene, selenite or metal sulfides, Pecourt says.

Pecourt 表示，量子点通常由半导体材料制成，例如石墨烯、亚硒酸盐或金属硫化物。

John knew about Stan's work with titanium disulfide cathodes and predicted that a metal oxide cathode, instead of a metal sulfide one, would enable more powerful batteries.

约翰知道斯坦利有关阴极使用二硫化钛的研究，并预测用金属氧化物代替金属硫化物作阴极会产生更强劲的电池。

For example, the island of Cyprus has 30 of these massive sulfide deposits that were once under the sea, and that's where the Ancient Romans got their copper.

例如，塞浦路斯岛有 30 个曾经位于海底的块状硫化物矿床，古罗马人就是在那里获得铜的。

Using the serial analysis method, researchers obtained space weathering information of silicates, oxides, phosphates and sulfides on the surface of a single particle of lunar soil collected by Chang'e-5.

利用系列分析方法，研究人员获得了嫦娥五号采集的月球土壤单个颗粒表面硅酸盐、氧化物、磷酸盐和硫化物的空间风化信息。

Another option was that small, burrowing animals were helping to move oxygen directly to the sulfide, except, the researchers had removed all of those before starting their experiment.

另一个选择是，挖洞的小动物可以帮助将氧气直接移动到硫化物中，不过研究人员在开始实验之前已将所有氧气都去除了。

Patients also seem to have a higher proportion of gut bacteria that produce sulfides, and often high sulfide production is correlated with periods of active inflammation as opposed to remission.

患者肠道内的产硫菌比例较正常人高，而肠道内硫化物产量的高低通常与炎症的活动期长短相关，但与缓解期无关。

Sometimes the chimneys are called white or black smokers because the erupting fluids full of minerals look like smoke rising out of the towers, but the whole accumulations are known more formally as massive sulfide deposits.

有时烟囱被称为海底白烟囱或黑烟囱，因为充满矿物质的喷发流体看起来像从塔中升起的烟雾，但整个堆积物更正式的名字是块状硫化物矿床。

These can only form under the ocean, but these days, when we mine for zinc, copper, or silver on land, we're often mining massive sulfide deposits that originally formed on the ocean floor millions of years ago.

它们只能在海底形成，但如今，当我们在陆地开采锌、铜或银时，我们开采的经常是数百万年前最初在海底形成的块状硫化物矿床。
