摘要
探讨了描述焊接气溶胶粒子谱非正态型分布的数学模型，以及将实测样本模型化的简明方法—图估法；给出了其分布函数的表达式，根据极限粒径参数ｄｍ，又可分为Ａ型、Ｂ型和Ｒ型分布，但它们的标准差σ却具有完全相同的表达式．
Two points are discussed. One of which is the mathematical model of non normal distribution of the particulate size, the other is a simple method estimated with the aid of a diagram modeling practical specimen. The expression of distribution function is given. Accor ding to the limit particulate diameter d m, distribution can be classified as A, B and R types. Formulas of their standard deviations are something in common.
