用 ANDERSEN生物粒子采样器观测了北京市传染病院病区室内外空气微生物粒子浓度及浓度分布。结果表明 ,北京市传染病院病区空气微生物粒子浓度室内高于室外 ,室内清洁区高于半污染区和污染区 ,室内春、秋季高于夏、冬季 ,室外秋、冬季高于春、夏季。病区室内空气微生物粒子浓度分布的高峰在第 3级 (3.3～ 4 .7μm)和第 5级 (1.1～ 2 .1μm) ,病区室外空气微生物粒子浓度分布的高峰在第1级 (>7.0μm)和第 5级
Using ANDERSEN biological particle sampler to observe the indoor and outdoor airborne microorganisms particle concentration and concentration distribution in infectious disease hospital of Beijing. The results showed that the airborne microorganism particle concentration in the infectious disease hospital in Beijing was higher than that in the outdoor. The indoor cleaning area was higher than the semi-contaminated and contaminated areas. The indoor spring and autumn were higher than those in summer, winter, outdoor and winter. The peak of indoor air microbial concentration distribution in the ward was at the third level (3.3-4.7μm) and the fifth level (1.1-2.1μm). The peak of outdoor airborne microorganism particle concentration distribution was in the first level (> 7.0) μm) and Level 5
