摘要：采用不同纤维滤材,对9.31～22.1 nm及25.1～604 nm粒径范围的气溶胶粒子的收集效率进行了初步探索,实验结果表明,在9.31～22.1 nm粒径范围内滤材的收集效率呈缓慢下降趋势,结果与经典的过滤理论一致,与文献结果存在差异,其原因有待进一步研究。

Abstract: The collection efficiency of aerosol particles at range of 9.31～ 22.1 nm and 25.1～604 nm is preliminarily explored by using different fibrous filters.The experimental results show that the collection efficiency of filters slowly decline with increasing of particle diameter at range of 9.31～22.1 nm. Good agreement is obtained between experimental results and classical filtration theory, and there is some difference from conclusion of literature. As for possible reason. The continuous experimental study is needed to explain the possible reason.
