摘要：

The diffusional growth of polydisperse aerosol was calculated as a function of expansion time, i.e.; time in which the temperature drop necessary for supersaturation-induced condensational growth is produced. At high nuclei concentrations and/or long expansion time only fractions of the ideal supersaturation (produced with small concentrations and fast expansion) are obtained. Large nuclei are activated earlier than smaller ones and consume so much vapor that smaller nuclei cannot possibly grow. This may cause a strong influence on the particle size detection limit. Therefore, great care is necessary to interpret condensation nuclei counter (CNC) measurements with concentrated polydisperse aerosols correctly. © 1979.
