摘要：

The performance of an ejector type dilution system has been investigated for mono- and polydisperse DES-particles in the size range between 0.1-mu-m and 2-mu-m using a Condensation Nuclei Counter and a Laser Particle Counter. By cascading up to four stages with a dilution factor of 10, overall dilution factors of up to 10,000 could be achieved. Within the accuracy of the measurement techniques used and within the statistical limits given by the rather low particle concentration downstream of the fourth dilution stage the dilution systems proved to work very well.
