| 摘 要： | 讨论了逆温破坏型熏烟（以下简称熏烟）过程及其浓度预测中的几个问题，介绍了熏烟地面浓度最大值（Ｃｆｍ）及其空间分布的正确计算方法。分析了对其影响的各种因素和高浓度区的延伸范围，Ｃｆｍ比最大地面浓度Ｃｍ大几倍，Ｃｆｍ〉Ｃｍ的范围可延伸到有效源高的７０倍。

| Abstract: | The mechanism and some questions in the concentration prediction of inversion break up fumigation(IBF)are studied.The correct algorithum for the maximum ground concentrat ion of IBF(Cfm)and the isoplet h of ground concentration of IBF is present ed.Various f actor that the Cfm depended on and t he ext ents of high concentrat ion are analysed.The Cfm is several times as large as the maximum ground concent rat ion of normal(Cm)and th e range of CfmCm is ext ended about 70 t imes as long as th e ef fect ive height of emission. |

| Keywords: | inversion break up fumigation(IBF) maximum ground concetration extent of high concentration of IBF |
