Spectral analysis mobility of atmospheric particles

There is analytical approach for estimate of spectral distribution of mobility of atmospheric particles considered in the article. The known laboratory practice of the analysis of ranges with use of volt-ampere characteristics of aspiration counters is taken as a basis. Because at such measurements there is no statistical material (sampling), the expedient assumption concerning nature of function of distribution becomes. As the most general analytical form of function of density of probability gamma distribution is chosen. Values of electric charge and mobility of particles in the range from 0.001 to 1.46 cm 2·V -1·s -1 are proved and systematized. The analytical receptions allowing to determine distribution parameters on the basis of the volt-ampere characteristic are proved.
