Figure 3: Time dependencies of the concentration (a) of a unipolarlycharged aerosol with the average unit elementary charge per particle under electrostatic scattering conditions and (b) of the ratio of the change in the total particle concentration N in the medium, which experiences coagulation and precipitation, to the change in the concentration of the particles which remain in the medium after electrostatic scattering, plotted as a function of the average size of the particles participating in these processes, calculated for q = e (dashed curve), l.l e (dotted curve), and 1.3 e (chain curve).
