摘　　要：基于联邦德国卡尔斯鲁厄核研究中心19次高架(H=160m)大气猕散实验资料,应用相关分析和符合指数d对轴向归一化扩散因子的预测值X_p和观测值X_o进行了统计比较,以检验高斯烟羽模式在高架源、大粗糙度地形条件下的有效性,研究中采用了四类稳定度分类方法和两组扩散参数系,结果表明符合指数d的预测性能好于相关系数。Based on correlation analysis and index of agreement d and used the information of 19 atmospheric dispersion experiments with releases at 160 m height at Karlsruhe Nuclear Research Center, the axial normalized diffusion factors Xp and X0 predicted and observed have been statistically compared so as to examine the validation of the Gaussion Plume Model for elevated releases over a terrain of major roughness. This paper presents 4 stability classifications and 2 diffusion parameter systems. The result shows that the prediction performance of d is better than correlation coefficient r.
