摘　　要：为了解教室室内颗粒物浓度变化规律和分布情况,本文采用了调查、实验监测、模拟的方式对教室内门窗开启方式,室内颗粒物浓度变化规律和分布进行研究。研究表明:秋冬季节,仅开内门、廊窗频率最高。室内无明显污染源时,室内外PM2.5浓度变化规律呈现明显的一致性。擦黑板和扫地对室内的颗粒物污染程度和由此产生的粒径呈现差异化。室内PM2.5浓度分布呈阶梯性衰减。In order to understand the variation and distribution of indoor particulate matter concentration in the classroom,investigation,experimental monitoring and simulation are used to study the opening method of doors and windows in the classroom,and the variation and distribution of indoor particulate matter concentration.Opening the inner door and the corridor window frequency is highest,in autumn and winter.The researches show that http://dict.youdao.com/javascript:void(0);the outdoor and indoor variation of PM2.5 concentration showed obvious consistency without obvious pollution source.Erasing blackboards and sweeping floors vary in the degree and size of indoor particulate matter pollution.The concentration distribution of indoor PM2.5 tends to decrease step by step.
