介绍了一种新型气溶胶采样器，该采样器可采集几种粒径较小的气溶胶颗粒物，并给出了操作步骤。该仪器的实验研究表明，(A)壁面损失可以忽略不计，(B)没有细菌颗粒的滑移，(C)该仪器非常灵敏，(D)颗粒大小区分使测定细菌气溶胶的颗粒谱成为可能。该采样器为评价颗粒物污染的健康危害提供了一种合适的手段。
A new type of aerosol sampler that collects airborne particles in several categories of decreasing particle size is described and procedures for its operation are given. Experimental studies with the instrument showed that, (a) wall loss is negligible, (b) there is no slippage of bacterial particles, (c) the instrument is extremely sensitive and (d) particle size discrimation makes it possible to determine the particle size spectrum of bacterial aerosols. It is also suggested that the sampler provides a suitable means of assessing the health hazard in particulate air pollution.
