| 摘 要： | 本文利用在湖南省耒阳地区和山西省神头电厂大气测试中获得资料,计算并比较了几种大气稳定度分类结果,分析讨论了这些分类方法的特点和适用性。建议取整层的平均稳定度代入高斯系污染物扩散模式,以表征自有效源高直至地面的整个扩散区域内的大气的湍流扩散能力。提出了将△T/△z分类法及P-T分类法用于高架源时的修正意见。

| Abstract: | Atmospheric stability determined by several classification schemes have been compared and analysed with the data obtained from the observations in Hunan and Shanxi. Applicability of these schemes was discussed in the paper. It is an proposal that average stability of layer from effective stack high to ground, which describe the turblent characteristics of the layer, may be used in Gaussian dispersion model in view of assumes of Gaussian. Two modified methods of gradient temperature and P-T were pretented for tall stack. |
