中文摘要: 分析了1985—1991一年冬季雨雪的酸度及化学组份资料。结果表明,降雪的酸雪频率各年均有不同,但都比同季中降雨的酸雨频率低;降雪酸度也比降雨低;降雪中弱酸性的酸雪出现次数最多,占总次数的4成;在酸雪中酸度值与电导率呈现显著的负相关。分析降雪的化学组份发现,降雪中SO2-4含量越来越高,Cl-含量呈下降趋势。阳离子中以NH+4为主。
Abstract:The data of the rain and snow acidity and the chemical components in winter from 1985 to 1991 are analysed.The results show that the frequence of acid snow is different every year,but.it is loWer than that of the acid f rain iii the same season.The snow acidity is less than that of the rain.The negative relationship between the snow acidity and the cond.uctivity is very clear.The analysis of the chemical components of snow suggest f that the SO2-4 content is becoming more and more the Cl- level tends to disctease,the NH+4 is of in4inly positive irans.
