Determination of size distribution of spherical polydispersions using scattered radiation data.

摘要: Results of a numerical experiment are presented to show that measurements the monochromatic light scattered by typical atmospheric aerosols (assumed spherical) can be used obtain meaningful information about variations particle number density with radius. Simulated three significant figure reliability taken at 1° intervals in range 80–180° analyzed using well-known least-square method retrieve as many twenty subintervals. For this purpose, it is necessary have some priori largest and smallest particles present polydispersion also refractive index material. The results showed components radiation parallel perpendicular plane scattering, i.e., polarization measurements, rarely contained extra size distribution. inverting Setzer’s [ Appl.
