摘要：

Experiments were carried out in order to measure the collection efficiencies, E, with which small-sized water drops (of radii between 400 and 500 mum) carrying electrical charge, Q(a) (from 5 x 10(-14) to 2 x 10(-11) C), collect monodisperse aerosol particles of radii between 0.35 and 0.88 mum. The measured values of collection efficiency were within the range 1-6% and were in good agreement with previous results. The measurements show an increase in E with increase in aerosol particle radius, drop radius and drop charge.
