    Wpływ kształtu ziaren na łączny rozkład ich wielkości wyznaczony metodą licznika Coultera
    (Wydawnictwa AGH, 2009) Peszko, Barbara; Niedoba, Tomasz
    Coulter Counter is one of the most common devices applied to counting ultrafine particles. Because of its construction, this device is able to count particles of sizes from 10% till 60% of the diameter of installed diaphragm. To obtain the full particle size distribution it is necessary to combine given partial distribution functions. To approximate the partial distribution functions given by various installed diaphragms, the Weibull distribution function was applied. For the researched material, which was diabase, the set of shape coefficients was calculated, which may be taken into consideration by individual partial distribution functions combination. The shape coefficients were calculated on the basis of image analysis method and of particle size distribution results. The given joined distribution functions, with and without application of shape coefficient, were compared and evaluated.
