摘要
通过实际焊接气溶胶粒子谱样品的处理,证实焊接气溶胶存在遵从非正态型分布的粒子群,图估法是处理这类分布简便、适用的方法.本文实测样品数量分布遵从非正态型分布,其体积分布也遵从,不仅它们的标准差σ表达式相同,其σ值也相同.
Particulate groups in the form of non normal distribution are proved to exist in welding aerosols through processing the samples of practical determined welding particulate sizes. The simple, suitable method to process this distribution is of chart estimation. The number and volume of practical determined samples are characterized by non normal distribution. Not only the formulas of its standard deviation are the same but their values are also the same. This is very important to reveal the characteristics of non normal distribution.
