摘要
对 2 0 0 2年 2月～ 2 0 0 3年 3月抚顺市的降水化学组份及时空分布特征进行了分析。抚顺地区降水是以硫酸型污染为主。抚顺市降水中主要阳离子组份是Ca2 + 、NH4 + ,主要阴离子组份是SO4 2 - 和NO3- 。由多元逐步回归分析可知抚顺市降水中NO3- 是酸化剂 ,Ca2 + 是碱化剂 ,对方程起作用的因子大小顺序是Ca2 + >Na+ >NO3- 。
This article analyses the chemical components of the of rain(snow) and features of time and space in Fushun during the period of Feb. 2002 to Mar. 2003.the main pollution caused by the rain(snow ) fall in Fushun area is sulphunic acid type .the main cation components in Fushun rain(snow) fall are Ca2+ and NH4+,while the main anion components are SO42- and NO3-.it is possible to get to know that NO3- in Fushun rain(snow) fall is sour turn ,as well as Ca2+ is in alkali turn ,by way of diverse gradual return analysis. the factor order from min to max is Ca2+>Na+>NO3- ,which effects on chemical formalas.
