摘要
本文探讨了大气颗粒物对酸的缓冲能力的参数化方法,提出了具有明确参数意义的缓冲方程,并用滴定实验进行了检验.结果表明,指数加线性形式的参数化方程对于描述大气颗粒物的缓冲能力及其时变关系是可以接受的.本文还初步讨论了大气颗粒物参数化方法的应用,表明这种参数化方法在数值模拟酸沉降下洗脱过程中大气颗粒物的缓冲作用可能比较合适.
A parametrization method for the acid-buffering capacity of airborne particu-lateS is discussed. The parametrization equations, in exponential plus linear form, and explanation of their parameters are given. Experiments showed that the form of the equation is acceptable in fitting the feature of the acid-buffering curves. Some aspects of this method in application to acid deposition models are also discussed briefly.
