摘要

Mass and size of the particles of the most refined fraction in aerosol systems with limited volume are determined via measuring the cinematic viscosity. The measurements of the latter have been performed when the system is left to stay after forming for a period of time, called delay time. The results for different aerosol volumes have been extrapolated at delay time tending to infinity, when there are left only the finest in size particles of the aerosol. They are interpretive as Aitken's nuclei of condensation in the atmosphere.
