| 摘 要： | 为更好了解污染物在复杂地形条件下的湍流扩散规律,2010年9月开展了一系列SF6示踪扩散试验,获取了SF6浓度数据,以此实验数据为基础,计算出SF6浓度分布在水平和垂直方向的扩散标准差、地面峰值浓度等参数,并与P-T-C扩散参数进行对比,总结得出了污染物在山区和平原连接处中性、稳定、强稳定等气象条件下湍流扩散规律。

| Abstract: | To better understand the turbulent diffusion law of the pollutants in complex terrains,a series of SF6 tracing diffusion experiments were carried out in September 2010 in the mountains and plains borders so as to retrieve SF6 concentration data.Based on the experimental data,the parameters of SF6 concentration in the horizontal and vertical proliferation of standard deviation and ground peak concentration etc.were calculated and compared with the P-T-C proliferation parameters.The turbulent diffusion laws in mountains and plains borders under neutral,stable and strong stable atmospheric conditions were summarized. |
