氮氧化物的污染控制对策

详细地介绍了日本针对不同的排放源－－固定源和流动源－－所采取的氮氧化物污染控制对策。对固定源，在实施全国统一的排放标准的基础上，对于一些工厂相对集中、污染问题严重的地区实施总量控制，同时积极促进技术革新以及降低氮氧化物的排放；对流动源所采取的措施有，确定不同车型汽车排放尾气递减的短期目标和长期目标，实施汽车氮氧化物法，积极推进低公害车的普及。通过采取上述措施，在日本，固定源排放的氮氧化物得到了较好

Controlling Measurementsof Nitrogen Oxydes Pollution

The article introduced in detail the controlling measurements in Japan for nitrogen oxydes pollution from stationary and mobile sources. For stationary sources, on the basis of national discharge standard, totalamount control is carried out and technical reform for decreasing nitrogen oxydes is promoted in areas of more plants and heavier pollution; For mobile sources, different types of autos are limited with different shortterm and long term standards, law of auto nitrogen oxydes is executed, and low pollution autos are promoted. With the measurements, nitrogen oxydes from stationary sources are well controlled, while nitrogen oxydes pollution from mobile sourcesis still serious in big cities. The article also analysed the situation of nitrogen oxydes pollution in China and presented the controlling suggestion.
