1·The rate of iron recovery of pyrite cinders is up to 90% by maturation treatment after pyrite cinders mixing with sulfur acid.

将硫铁矿烧渣与硫酸混合后，经过熟化处理可使烧渣中铁的回收率达到90%以上。

2·The wet process consisted of roasting, sulfur acid pretreatment and chlorination leaching of gold is examined. The results show that gold leaching rate is 97.95% and silver leaching rate is 79.86%.

本研究采用焙烧-硫酸预处理-氯化湿法工艺从其中回收金，金浸出率为97.95%，银浸出率为79.86%，效果令人满意。

3·Sulfur dioxide, a major contributor to acid rain, is an especially serious pollutant because it diminishes the respiratory system's ability to deal with all other pollutants.

二氧化硫是酸雨的主要成因之一，它是一种特别严重的污染物，因为它会降低呼吸系统处理其他污染物的能力。

4·Look for cleansers with salicylic acid, glycolic acid, benzoyl peroxide or sulfur.

寻找含有水杨酸，乙醇酸，过氧化苯甲酰或硫的洗面奶。

5·Although not covered by the rules, sulfur dioxide also could drop up to 90 percent because it would be filtered out by the same technology that controls hydrochloric acid.

尽管二氧化硫没有被纳入到此项法规中，但是由于控制氯化氢的技术也会去除二氧化硫，因此二氧化硫的排放量也会下降达90%。

6·Vegetation in the surrounding area has been destroyed by acid rain due to high sulfur dioxide emissions.

二氧化硫的高排放引起的酸雨使得周围的植物遭到大面积破坏。

7·Cremation puts harmful gasses into the air including dioxins, mercury vapor from dental fillings, hydrochloric acid, carbon dioxide and sulfur dioxide.

火葬向大气排放的有害物质有：二恶英、水银蒸汽(如果死者有假牙的话)、盐酸、二氧化碳和二氧化硫。

8·Huge amounts of sulfur dioxide added to the atmosphere created acid rain, disrupted regional climate and left a lingering fog shrouding parts of the Northern Hemisphere.

大量的二氧化硫进入大气中形成酸雨，扰乱局地气候，在北半球形成了一个雾气笼罩的区域。

9·Finally, Marsulex will install a new scrubber at Chemtrade’s sulfuric acid plant in Cairo, Ohio, to meet lower sulfur dioxide limits by July 2011.

最后，马苏莱将在俄亥俄州开罗市的硫酸厂安装上新的脱硫器，以在2011年7月前达到降低二氧化硫的目的。

10·A fresh supply of yellow froth (probably the same type of elemental sulfur found in the cool acid-brine crater lake at Kawa Ijen) is brought up by the plume and pushed out toward the crater wall.

一个新的黄色气泡(与在Kawa Ijen“冷酸海水”火山湖中的元素硫是同一类)是由热烟柱带出湖面，并推向岩壁。
