| 摘 要： | 对1986年春季广州地区酸雨综合观测的雨滴谱和离子成分资料表明:春季有频繁的酸雨出现，其中SO2-4, NO-3、NH+4和Ca2+四种离子成分是影响雨水酸性的主要因素。由于春季降雨常是间歇性小雨，雨滴谱型窄，雨滴均方直径仅0.5mm左右，这种降雨类型有利于冲洗大气中的气溶胶粒子和污染气体。雨水酸度和电导率随降雨过程的延续而呈下降趋势。

| Abstract: | A Synthetic observation of acid rain was done in Guangzhou Area in spring,1986.The data of spectrum of raindrops and ionic components showed as following There were acid rain in spring frequently in this region, SO2-4、NO-3、NH+4、and Ca2+ had an effect on acidity of rain and were main factors. The spectrum of raindrops is narrow and the ■=0.5mm. This kind of precipitation was useful for aerosol and pollutant gases to be washed out. Acidity and conductance of rain decreased with the time of precipitation process. |
