• 摘要：文章利用大气边界层风速廓线的理论和实验研究结果,重新推导了高斯扩散沉积模式中烟轴高度、地面反射系数及输送因子表达式,从而导出了能描述风速随高度变化的新的高斯扩散沉积模式。 文章还利用数值计算的结果讨论了风速廓线对地面相对浓度的影响。

• Abstract：In this paper; the expressions of plume axis height, reflecting coefficient and transporting factor in Gaussian Diffusion-Deposition Model are derived by using theoretical and experimental results in planetary boundary layer in order to obtain a new Gaussian Diffusion-Deposition Model that could be used to describe variation of wind speed with height.The effects of wind speed profile on relative ground-level concentrations are also discussed by using the calculated results obtained.
