飞沫气溶胶污染源特性研究现状
Research situation of characteristics of aerosol droplet pollution sources
摘要：
综述了近年来关于飞沫气溶胶污染源特性的实验研究。给出了飞沫气溶胶污染物被以如打喷嚏、咳嗽、说话和呼吸等不同方式射入室内时的速度与流量、角度与开口面积、温度、粒径分布与浓度等特性参数。分析了特性参数的影响因素，为研究气溶胶污染物在室内的传播提供参考依据。指出了目前污染源特性实验研究存在的不足。
Abstract：
Reviews the experimental studies on the characteristics of the aerosol droplet pollution sources in recent years. Presents the characteristic parameters of aerosol droplet pollution sources, including velocity and flow rate, angle and opening area, temperature, particle size distribution and concentration, when being injected into the room in different ways such as sneezing, coughing, talking and breathing. Analyses the influencing factors of the characteristic parameters, providing references for studying the propagation characteristics of aerosol contaminants in the room. Points out the current deficiencies of the experimental study on pollution source characteristics.
