摘　　要：采用示踪气体稀释法对选定的双单元建筑物的换气速度和内部流动进行了测量,以期建立一种实际测量的方法,同时获得一些有用的数据。测量结果表明,选定的建筑物具有令人满意的换气速度,内部流通良好,可满足室内空气质量的要求,但对污染事故的屏蔽能力较差。本工作可以为研究室内空气质量和建筑物屏蔽因子提供一些借鉴。Air exchange rates and interior flowing of a two-units building is determinated using tracer-gas dilution method in this paper in order to creat a actual determinaton method and get some useful data at the same time. The results indicate that the selected building has satisfactiory air exchange rates and interior flowing, however, low shield cability. This work can offer a reference for the studying of indoor air quality and shield factor of building.
