There's water and there's sulphur dioxide.

这水分子，这硫分子。

And that sulphuric acid is made by sulphur dioxide coming out of volcanoes on the surface.

这些硫酸来源于硫产生于地表的火山。

But there was no incentive for the power plants to stop emitting sulphur dioxide.

但发电厂没有动力停止排放硫。

Sulphur dioxide and nitrogen oxide combine to form acid rain.

【form】硫和氮物结合形成酸雨。

The sulphur dioxide level in the air was 32 parts per billion.

【part】空气中硫的含量十亿分之三十。

The rest of the gas is nitrogen, carbon dioxide, sulphur dioxide, methane, ammonia and hydrogen.

剩下的气氮气、碳等气。

They're carrying devices that measure gases, especially sulphur dioxide, which can pose a danger to health and even be fatal.

他们携带测量气​​的设备，尤其硫， 这可能对健康构成威胁， 致命的。

Fumigants such as hydrogen cyanide, sulphur dioxide and DDT itself are now regarded in most places as too toxic to use.

氰氢、硫和滴滴涕等熏蒸剂本身现在在大多数地方都被认为毒性太大而无法使用。

Sulphur dioxide is particularly influential because of how it combines with water to form sulphuric aerosols—a light-scattering haze which hangs in the sky.

硫的影响尤其大，因为它与水结合形成硫磺气溶胶——一种悬浮在天空中的光散射薄雾。

Gas-fired stations emit much less carbon dioxide, per unit of electricity, than coal, which also gives off all sorts of other nasties when burned, from sulphur dioxide to mercury.

生产同一单位的电，燃气发电厂排放的碳比燃煤发电厂排放的少。除此之外，煤在燃烧时也会产生各种有害气，包括硫和汞。

This would involve using sulphur or hydrogen sulphide aerosols so that sulphur dioxide would form clouds, which would, in turn, lead to a global dimming.

气雾剂的成分主要硫或氢硫，这样一来硫就会形成云层，因而就会实现全球变暗。

Older volcanic rocks tend to emit less infrared, say the researchers, because carbon dioxide and sulphur dioxide in the planet's atmosphere weather the rocks and change their composition.

研究人员说，较旧的火山岩往往发出较少的红外线，因为碳和硫在地球大气中使岩石风并改变它们的成分。

For years, its power stations had been emitting large amounts of sulphur dioxide, which was falling back to Earth as acid rain, causing harm to plants, aquatic animals and infrastructure.

多年来，它的发电站一直在排放大量硫，这些硫以酸雨的形式回落到地球上，对植物、水生动物和基础设施造成伤害。

The idea is to inject sulphur dioxide—or perhaps other chemicals such as calcium carbonate or powders made of aluminium or diamonds—not into the troposphere, but the stratosphere, which begins up to 20km above the surface.

这个想法将硫——或者可能其他学物质， 如碳酸钙或由铝或钻石制成的粉末——不注入对流层，而注入平流层， 平流层开始于距地表 20 公里处。
