复杂地形条件下大气扩散六氟化硫示踪实验研究

Sulfur Hexafluoride-based Atmosphere Diffusion Trace Experimental Study in Complex Topography

介绍了在复杂地形条件下为求取烟羽轨迹和扩散参数而进行的 SF6示踪实验。SF6从塔顶处释放 ,采用居民区面源布点与可能的弧线布点相结合的方法确定取样点 ,气相色谱 -电子捕获检测法分析样品 ,并用最小二乘法计算每次实验的扩散参数。

This paper presents a sulfur hexafluoride based experimental study that was made under complex topographical conditions for the purpose of availability of plume trajectory and diffusion parameters.The study was completed through release of SF 6 from the top of a 100 m tower,and combined sample collection both in residential area and along curve.Sample analysis was made by gas chromatography electron capture method,with diffusion parameter calculated with the minimum square for each experiment.
