空气微生物采样技术的发展，至今已有百余的历史。世界各国对空气细菌的监测多使用裂隙式的撞击法作为采样技术，采集悬浮在空气中的微生物尘粒，而这种微生物尘粒又可随人体呼吸运动进入人体呼吸道内，因此具有重要的卫生学意义。此外这种采样仪器不受气流影响，采样量准... The development of airborne microorganism sampling technology has so far had over a hundred years of history. The airborne bacteria surveillance in many countries in the world uses the fissure-type collision method as a sampling technique to collect the microbial dust suspended in the air. The microbial dust particles can also enter the human respiratory tract with the respiratory motion of the human body and therefore have important health Significance of learning. In addition this sampling device is not affected by the air flow, the sample volume is ...
