摘要：

Aerosol refers to an assembly of liquid or solid particles suspended in a gaseous medium long enough to enable observation or measurement. Aerosol concentration is one of index for evaluating environmental quality. Filtration by filter media is usually used to collect aerosols, where the efficiency of the filter should be known. A convenience method has been developed for determination of the filter efficiency as aerosol size and air velocity.
