Finally, the influence of various flows on the atmospheric diffusion is analyzed in combination with the characteristics of the turbulence.
最后，结合湍流特征，分析了不同流场对大气扩散的影响。
Results of homogeneous turbulence experiments show that the diffusion coefficient varies with the size and density of sediment particles, just as indicated by the theoretical analysis.
表达式显示出的扩散系数随垂向脉动流速均方根值和颗粒粒径、密度而变化的趋势与实验结果吻合。
In certain locations where atmospheric turbulence is lacking, smoke originating at the surface of the earth is dissipated largely by molecular diffusion.
在某些气体湍流缓慢的区域中，地球表面产生的烟雾很大一部分是通过分子扩散而消散的。
