发现污染物在土壤中的质量浓度分布与渗流速度、作用时间、扩散系数等有关。

The results showed that the intensity distribution had relation with the velocity of percolation, time, coefficient of convection and diffusion.

结合风速等气象要素对污染物扩散、 传输和清除进行的分析可知， 监测期间风速对污染物浓度分布起主导作用， 气压等其它气象状况对污染物浓度分布也有一定的影响。

Wind speed played a leading role and other meteorological factors also have some effect, which resulted from the influence of the meteorology on diffusion, transmission, elimination of air pollutants.

该模型能定量地描述气体扩散地面浓度分布场，能快捷和科学地预测浓度和源强、风速、大气稳定度以及时间空间等的关系。

The model could describe the concentration field quantitatively, and predict the relationships between concentration and source strength, wind velocity, atmospheric stability, space-time and so on.
