| 摘 要： | 简要介绍了2001年-2007年南通市区降水中硫酸根占比44．21％，硝酸根占比15．74％，氟离子占比7．89％；铵离子占比12．26％，钙离子占比11．51%，钠离子占比3．85％；多年阴、阳离子平均占比呈双曲线对称管道，1～4月管道中酸雨频率由高向低，5～9月管道中酸雨频率波动不大，10～12月管道中酸雨频率由低向高；同时酸雨频率由2001年升高到2007年的程度，与阳离子占比下降6．9个百分点，阴离子占比上升6．9个百分点相关。

| Abstract: | This paper introduces the ions' percentage of rainfall in Nantong City from 2001 to 2007,which SO2-4 is 44.21%,NO-3 is 15.74%,Cl-is 7.89%,NH+4 is 12.26%,Ca2+ is 11.51%,Na+ is 3.85%.the hyperbola of average percentage of anion and cation is symmetrical and it showes that the frequency of acid rain decreases from January to April,while it is on the contrary from October to December,the variation of the frequency is small from May to September.The increased frequency from 2001 to 2007 is related to 6.9 cation ... |
