【摘要】 本文介绍了酸雨的概念,分析了自然界S、N循环、大气粒子、气象和地形条件对降水的影响,研究表明仅硫循环就可以使降水的pH值降低至4.5;大气粒子不仅起着降水凝结核的作用,而且还有清除大气中酸性物质,减少酸沉降的作用;气象和地形条件决定酸性物质的迁移扩散和酸雨的地域分布。最后介绍了酸雨的危害及其控制措施和对策。更多还原

【Abstract】 This paper introduces notion of acid rain. Eeffect of the cycle of sulfur and nitrogenin nature, atmospheric aerosols, weather and landform in precipitation were discussed. The study show that the cycle of sulfur alone may make pH of precipitation decrease to the lowest value of 4.5; the atmospheric aerosols acts as core of precipitation, but it also removes acid matter in air and decrease acid sedimentation; the weather and landform decide diffuse of acid mater and distribution of acid rain. Finally, the harms and controlling measures of acid rain were stated.更多还原
