摘　　要：选取北京城区和郊区24户住宅，对室内和室外空气中PM:。进行同步数据采集，并结合《时间活动模式调查问卷》研究室内外PM:。污染特征。研究结果表明，2/3的居室在测试时间内PM:。曰平均浓度超标；室内外PM:。具有显著正相关性；室内外温差和室外风速与室内PM:。均呈显著负相关，室外相对湿度与室内PM:。呈显著正相关。室内吸烟、手工打扫、机械打扫、蒸（焖）、炒（炸）和炖（熬）时段的1/〇(室内/室外）比分别是夜间无明显活动时段的1.56~3.05倍，是白天无明显活动时段的1.02~1.49倍。应综合考虑室外污染状态、气象条件及室内人员活动状态采取措施降低居住建筑室内PM:。污染。Indoor PM10 concentration was monitored continually in 24 households located in Beijing urban and suburban areas, and the time activity pattern questionnaire was filled in by family member. Outdoor PM10 concentration was collected simultaneously. The study results showed that indoor daily average of PM10 concentration were up to the standards in 2 /3 of households. Indoor and outdoor PM10 concentration has a significant positive correlation; indoor and outdoor temperature difference and outdoor wind speed are significantly negatively correlated withindoor PM10 ; outdoor relative humidity is significantly positively correlated with indoor PM10. 1 /0 ratio of the smoking,manual cleaning, machinery cleaning, steam, fry, and stew period is 1. 56 ~ 3. 05 times of no apparent activityperiod at night, and 1 ? 02 ?1 ? 49 times of no obvious activity period in the day. Therefore, to reduce indoor PM10 pollution in the households, the appropriate methods should be used on the basis of comprehensively considering outdoor PM10 pollution, outdoor meteorological conditions and indoor personnel activity state.
