| 摘 要： | 利用数值模拟确定致病微生物浓度的时空分布,建立了基于瞬时浓度判据和积累浓度判据的污染物暴露评价模型,得到了建筑群内瞬时风险区域和人们在污染区域的最大停留时间。结果显示:瞬时风险区域面积基本与微生物生长曲线一致,即在2000s时达到最大,然后逐渐减小,至6000s后基本不变;最大停留时间与微生物的增长率有关,增长率大,最大停留时间变小。

| Abstract: | Based on the space-time concentration of pathogenic microorganisms of numerical simulation,the evaluation model of exposure risk in a building group was established.In the model,the instantaneous risk area and the largest resident time for person were obtained by introducing the instantaneous concentration criterion and the accumulated concentration criterion,respectively.The results shown that the change of instantaneous risk area was consisitent to the growth curve of virus.It increases to its peak value ... |
