低气阻稳流型空气微生物采样器陈烈贤周淑玉鲁波空气微生物污染程度是评价环境空气质量的重要指标之一。采集空气微生物的采样器，种类较多，性能各异。笔者在此介绍能够同时测定可吸入与非可吸入生物微粒的两级筛孔撞击式空气采样器的原理、结构及流量控制。１原理撞击式... Low Air Resistance Steady Flow Airborne Sampler CHEN Lie-Xian ZHOU Shu-Yu LUBO The degree of air microbial contamination is one of the important indexes to evaluate the ambient air quality. Collection of air samples of microorganisms, more types, different performance. The author here introduces the principle, structure and flow control of a two-stage sieve impact air sampler that can simultaneously measure inhalable and non-inhalable biological particles. 1 principle impact type ...
