| 摘 要： | 根据2010年9月,在北京某试验场开展的一系列SF6示踪扩散试验,以及获取的SF6浓度空间分布数据,以高斯模式和计算机拟合为基础,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,分析、总结出了在典型地理(山区和平原连接处)和边界层条件下燃烧对SF6扩散的影响。通过试验及分析可知,燃油对试验区域气流产生了明显扰动,但具体原理有待于进一步分析。

| Abstract: | A series of SF6 tracing diffusion experiments were carried out in September 2010 in Beijing and SF6 concentration data were retrieved.Based on the experimental data,parameters,including the standard deviation for horizontal and vertical SF6 concentration,ground peak concentration etc were calculated by Gaussian mode and computer fitting.The effects of combustion for SF6 diffusion in typical geographic（mountains and plains connections）and boundary layer conditions were analyzed and summarized.Results show that the fuel gas flow of the test area is in obvious disturbance,but the exact mechanism needs further analysis. |
