摘要
用ＤＭＰＳ方法测定了大量焊接气溶胶粒子谱，按其分布特征，可归纳为正态型和非正态型两大类．本文主要探讨焊接气溶胶的正态型分布模型及其适用性，以及用图估法处理实测粒子谱的方法．模型与粒子谱实例取得了较好的一致性．
A large number of particulate sizes of welding aerosols is measured by means of DMPS method. They can be classified into two categories of normal and non normal distributions. It discusses mainly the normal distribution model of welding aerosols and its adaptability, and the method of dealing with practically measured particulate sizes by means of the method estimated by diagram. The model is well verified sample of practical particulate size.
