China's soaring energy needs and reliance on coal have made it the world's biggest emitter of sulphur dioxide, which causes acid rain and respiratory problems.
中国飙升的能源需求以及对煤炭的依赖，已使其成为全球最大的二氧化硫排放国——二氧化硫能导致酸雨和呼吸道疾病。
According to Liu, the population controls have kept sulphur dioxide emissions down by 17.6% and the main source of water pollution by 30.8%.

The cheapest option could be to use giant mid-air refuelling aircraft, such as the US air force's KC-10 Extender, filled with sulphur dioxide or hydrogen sulphide gas.
最便宜的方案是使用巨型空中加油飞机——例如美国空军的KC-10“补充者”空中加油机（KC-10Extender），装满二氧化硫和硫化氢气体。
Up to now, sulphur dioxide has been regarded as one of the most serious of these pollutants.
到目前为止，二氧化硫一直被看作是这些污染物中最严重的一种。
