摘　　要：雾霾天气对人类生产生活的影响受到越来越多的重视,然而实际雾霾天气的不确定性限制了研究工作的开展。结合雾霾组成特点,根据溯源法得出雾霾的人工模拟方法,设计并搭建了一套人工模拟雾霾的实验装置,该装置由模拟燃煤排放、模拟交通排放(如汽车尾气)、粉尘扬尘及含有一定雾水电导率的盐雾发生器等4个单元部分组成。设计一个高3.2 m、直径4 m的圆柱有机玻璃模拟腔体,在腔体不同位置设置5个监测点,采用粒径谱仪,粒子计数仪、温湿度传感器等对形成的雾霾环境进行颗粒物粒径分布和浓度监测。通过调试实验,该系统最终可实现稳定的高浓度雾霾环境,可用于研究材料在雾霾环境下的加速老化实验。Effect of fog-haze on the work and human life was received more and more attention,however the research work was limited by the uncertainty of the actual fog-haze weather. To overcome this difficulty,this paper analyzed the haze ingredients in the typical regions,and got the haze formation method by tracing the roots,designed four unit simulation apparatuses of generating haze-fog,such as emissions of burning coal,emissions of burning oil（for example of motor vehicle exhaust）,earth and dust,humidity of certain conductivity. A cylindrical chamber made of plexiglass was produced,which is three point two meters high and four meters in diameter.Six monitors were set up at different positions of chamber. Temperature,humidity,particle distribution and concentration were monitored by temperature and humidity sensors,particle spectromter,airborne particle counter and so on. In short,the system could achieve haze environments of different concentrations through adjusting simulation parameters,and could be used to the accelerated aging test.
