摘　　要：大气降水的酸碱性通常认为是受大气中的SOX和NOX的浓度大小控制的,但是通过研究发现,大气降水的pH值与这些物质的浓度大小无明显关系,并且与降水中的阴阳离子组成也无明显关系,但却随大气中的TSP浓度的变化而发生明显且有规律的变化。据此认为大气中的TSP值不仅可以用来表示大气环境的颗粒污染物的污染程度,而且还可以用来反映大气降水的酸碱程度、解释大气降水酸碱性成因以及提前预测预报大气降水的酸碱性。The acidity and alkalinity of atmospheric precipitation are usually considered to be under control of the concentration of SOx and NOx. However, the author found through her studies that PH value in atmospheric precipitation has no clear relation with the concentration of these substances and also no clear relation with the composition of their anions and actions, but it varies clearly and regularly with the change of TSP concentration in atmosphere. The author deems that TSP concentration in atmosphere can not only indicate pollution degree of atmospheric particle contaminants, but also reflect the acidity and alkalinity of atmospheric precipitation, explain the cause of its acidity and alkalinity formation and forecast its acidity and alkalinity in advance.
