摘要： 利用南票地区野外平衡球观测资料分别计算了不同稳定度下的大气扩散参数,并将不同稳定度下的结果与其他扩散参数进行了比较。结果表明:在不同条件下,由于南票地区地形相对复杂,该地区的σy和σz值均大于同级Briggs公式给出的结果;试验结果仅适用于远距离的高架源排烟扩散计算,而对于近距离(如2 km以内),则需采用其他试验结果。

Abstract: According to the observational data from a field balance-ball in Nanpiao area,a series of air diffusing parameters in different stabilization were calculated.These parameters obtained in different atmospheric stabilization were compared with other material values.As a result,the values of σ_y and σ_z in different atmospheric conditions were higher than those from Briggs expressions in the same rank for the comparatively complex topographty in Nanpiao area.It indicated that the result of this experiment only can be used in calculating the letting smoke pervasion of far distant and high headstream.When the distance was within 2 kilometers,other experiment results ought to be used.
