This is caused by the tidal diffusion asymmetry in which the vertical turbulencediffusion in the ebb tides is weaker than the one in the flood tides.
动力分析表明这是由潮扩散的不对称性造成的，即落潮期间垂向湍流扩散比涨潮期间弱。

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.
