The forming, diffusion and momentum transfer of the red phosphorus smokescreens and the kinetic characteristic of the different scale particles in smoke cloud are researched in this paper.
本文研究了赤磷基烟幕云团的形成、扩散规律和动量输运，及其烟幕云团中不同尺度微粒的运动性质。

The releasing characteristic of soil phosphorus can be exactly depicted by parabolic diffusion equation.
抛物线扩散公式能很好地拟和土壤磷素释放特征。
