四川大气颗粒物对酸沉降的缓冲作用

The Buffer Effect of Air Particulates on Acid Precipitation

本文主要是根据四川的具体情况,采集了不同地区的大气颗粒物,研究了颗粒物溶样的初始 PH 值及其对酸性降雨的缓冲能力,并与其它省市进行了对比。实验得出各地颗粒物缓冲能力的大小,基本上反映了四川酸雨轻重的分布现状,研究结果对了解四川酸雨成因有着重要意义.

The initial pH value of air particulates solution and its buffer capacity have been studied by using the air particulate samples collected from different regions in Si Chuan province,and the result was compared with that of other provinces.The value of the buffer capacity basically reflects the distribution of the acid rain damage in Si Chuan.The result is very important for understanding the cause of acid rain in Si Chuan.
