| 摘 要： | 测定了厦门市几个代表点1993年3月至7月间雨样的pH值，并用ICP－AES方法测定了S、Ca、Mg等元素的浓度，实验结果表明，各区域雨样的pH值不仅与致酸污染物的排放(主要表现在S元素浓度上)有关，而且受到该区域的地理条件的影响，体现出酸雨的形成是致酸因素与致碱因素互相平衡制约的结果的一般规律。根据单场雨的分段分析数据，总结出pH值随降雨过程变化的几种模式，并分析了其成因。

| Abstract: | Acid precipitation has been observed in several representative sites in Xiamen city fromMarch to July in 1993. The field distribution and the pH variations as well as the possible mecha-nism are discussed. The experimental results indicate that the pH values of acid rain are con-trolled by both the concentrations of sulfate ions in the samples and the environmental conditionsin the sampling areas. |
