灰尘在空气中的分布规律研究

The Distribution Regularity of Atmospheric Dust

应用概率统计理论,对目前人们普遍关注的"扬灰层"问题构建模型,给出了在高层建筑附近,灰尘浓度随着高度变化的分布规律,并由此得出"扬灰层"存在的结论。

With the application of probability theory,we made up a model as to the widely concerned'dust-floating-layer' problem.And in so doing,we found out the distribution regularity of the dust density around the high building as its height increases.Also we can prove the existence of 'dust-floating-layer' and figure out the height it appears.
