摘要
建立了一个点源排出的活性污染物以及其在大气中化学转化形成的次生物扩散方程。对阶函数分布排放源求得了活性污染物及其次生物浓度解析解。以某光气源事故泄漏为例对影响光气和它的次生物氯化氢地面浓度的重要参数进行了灵敏度分析。
The sets of diffusion equations are presented for reactive pollutant from a time -varied point source and secondary pollutant formed by the transformation. Three-dimensional concentrations of the reactive pollutant and its secondary pollutant are analytically given for step function type source. As an example, the results of the analysis have been applied to estimate the ground level concentrations of COC12, released accidentally to the atmosphere and its secondary pollutant, HCI, and sensitivity-analysis of some important parameters have conducted.
