摘要
文章依据常用的三种粉尘粒度分布规律（对数分布、对数正态分布和罗森分布），研究并编制了计算三种分布规律的计算机程序，同时引入相关系数检验法对模拟结果进行效果检验，从而求出近似度最高的分布规律。
The computer programs for calculating three dust distributions are studied and compiled in accordance with the three dust distributions(logarithmic distribution,logarithmic-normal distribution and Rosen distribution),and tke examination method of correlation coefficient is introduced for the effect examin-atiol1 of the simulated results,thus calculating the ditribution with high degree of pproximation.
