| 摘 要： | 逆温破坏型熏烟(以下简称熏烟)模式的传统计算过程忽视其非定常性特征,计算结果与监测值通常有较大偏离,与环评技术导则的要求不符。通过分析各种参数及变量的相互关系,厘定Cf(熏烟浓度)和Xf(发生熏烟距离)的算法并通过计算机编程进行计算,探求了熏烟计算过程中纳入非定常性特征的解决方法。实例对比计算表明新算法符合指数d为0.68,传统算法符合指数d为0.34和0.44。

Study on Computational Method for Inversion Break up Fumigation |
| |
| Abstract: | The abnormity of inversion break up Fumigation(IBF) is commonly ignored during its calculation,resulting in imprecise result and failng to satisfy to the requirement of Guide of Environmental Assessment.Based on analyzing the relative relationship between each parameters and variables,a computational method for determining C_f(concentration of IBF) and X_f(extent of IBF) is suggested combining with iterative arithmetic and program for the calculation.Purposely,it gives a solving way for the feature of abnormity in IBF.An example of contrastive calculation gave coincidence indexed was 0.68 for rendered method,and 0.34 or 0.44 for traditional ways. |
