一、设计目的《医用基础化学》第4章第90面“阅读材料:酸雨”中,介绍了酸雨产生的原因是汽油、柴油等含硫化合物燃烧及金属冶炼时释放出二氧化硫等所致,强调了二氧化硫和二氧化氮是主要的大气污染物,是形成酸雨的主要物质。酸雨有很大的危害,能直接破坏农作物、森林、草原,使土壤、湖泊酸化,还会加速建筑物、桥梁、工业设备、运输工具及电信电缆的腐蚀。在人教版普通高中课程标准实验教科书《化学1(必修)》第4章第3节“硫和氮的氧化物”、义务教育教科书《化学》第2单元课题1 First, the design purpose of “Medical Fundamentals of Chemistry,” the first 90 in Chapter “reading material: acid rain ”, describes the acid rain is caused by gasoline, diesel and other sulfur compounds combustion and metal smelting caused by the release of sulfur dioxide , Stressing that sulfur dioxide and nitrogen dioxide are the main air pollutants and the main substances that form acid rain. Acid rain can be very damaging, destroying crops, forests and grasslands directly, acidifying soils and lakes, and accelerating the erosion of buildings, bridges, industrial equipment, vehicles and telecom cables. In the PEP ordinary high school curriculum standard experimental textbook “Chemistry 1 (compulsory)” Chapter 4, Section 3 “sulfur and nitrogen oxides ”, compulsory education textbook “chemistry”
