【英文篇名】 Research on concentration distribution of inhalable particles in meeting rooms 【作者中文名】 曹明; 刘刚; 沈恒根; 【作者英文名】 Coo Mong Liu Gang Shen Henggen Donghua University; Shanghai; China; 【作者单位】 东华大学; 【文献出处】 暖通空调, Heating Ventilating 可吸入颗粒物; 影响因素; 【英文关键词】 meeting room; inhalable particle; influencing factor; 【摘要】 在进行了大量实际监测的基础上选择两处有代表性的会议室作为监测对象,分析了室内颗粒物质量浓度分布情况及影响因素。研究结果表明,室内小粒径(小于1μm)颗粒物质量浓度所占比例大且存在状态稳定,大粒径颗粒物的质量浓度波动主要是由室内人员走动等造成的。 【英文摘要】 Based on a great deal of field monitors choosing two typical meeting rooms as supervision objects,analyses the mass concentration distribution and influencing factors of indoor particles.The result indicates that in meeting rooms,smaller size(less than 1μm)particles have higher mass concentration than others and exist stably,and that the fluctuation in mass concentration of bigger size particles is caused by peoples' moving and other factors.
