摘　　要：本文通过建立质量平衡方程对西安市某办公建筑室内颗粒物浓度进行了理论分析,并对该建筑室内外PM10和PM2.5的质量浓度进行了实时监测。结合线性回归方程、室内外监测浓度线性拟合曲线及室内浓度随时间的指数拟合曲线,对该普通办公房间室内颗粒排放源及室内颗粒浓度变化特征进行了研究。结果表明,该建筑室内PM10的平均发尘为7.93～12.48 mg/h,室内PM2.5的平均发尘为2.89～4.08 mg/h;室内PM10和PM2.5呈现指数变化且随时间呈下降趋势。This paper conducts a theoretical analysis on the indoor particle matter concentration of a certain office building in Xi＇an through establishing a mass balance equation and conducts real-time monitoring of indoor and outdoor mass concentrations of PM10 and PM2.5 for the building.In combination with equation of linear regression,linear fitting curve of indoor and outdoor monitoring concentration as well as exponent fitting curve of indoor concentration along with time,researches are conducted on indoor particulate emission source and indoor particulate concentration change feature of common office buildings.The results show that average dust emission at PM10 in the building is 7.93~12.48 mg/h,average dust emission at PM2.5 in the building is 2.89~4.08 mg/h;indoor PM10 and PM2.5 take on exponent change and are on a declining curve along with time.
