本文的目的是对亚微米液体颗粒堵塞纤维过滤器过程中发生的现象进行定性描述。同时监测了过滤介质的压降和效率随单位面积产生的气溶胶质量的变化。所描述的不同实验方法收敛于对过滤器堵塞的相同描述，该场景被分为四个步骤。对操作条件的影响进行了研究，强调了过滤速度、过滤器的性质和气溶胶的物理化学特性的重要作用。(C) 2003 Elsevier Ltd.版权所有。
The aim of this article is to contribute to the qualitative description of the phenomena occurring during the clogging of fibre filters by submicron liquid particles. The changes in the pressure drop and efficiency of the filtration media in relation to the generated aerosol mass per unit area were monitored simultaneously. The different experimental approaches described converge on the same description of filter clogging, the scenario being broken down into four steps. A study of the influence of the operating conditions was carried out which highlighted the significant roles of filtration velocity, the nature of the filter, and the physico-chemical characteristics of the aerosol.
