摘要
对我国大气环境界普遍采用的模式计算方法进行了分析，指出了模式计算结果的多样性，地面平均风速、最大地面浓度公式、面源模式、多次反射计算、熏烟模式和静风公式的影响，分析了烟气抬升公式的问题，推荐一个新的烟气抬升公式。对采样时间和布点也进行了分析。最后对这些问题的产生和解决办法提出了建议。
The model calculation methods commonly used by the Chinese atmospheric environment scientists were analyzed,and the diversity of the calculation results pointed out. The impacts of the average surface wind velocity,the equation of maximum surface concentration,the surface resource model,the multi\|reflection calculation,the fumigation model and the equation of calm wind condition were also analyzed. The problem of the fume elevation equation was analyzed and a new equation recommended. The choosing of sampling sites and time was also analyzed. In the conclusion,the reason for the above problems was analyzed and the solutions recommended.
