AI Technical Summary
Existing two-dimensional particle size measurement methods cannot accurately obtain particle size information of specific phases or components in non-dispersed samples, and three-dimensional measurement equipment is expensive and time-consuming, resulting in measurement errors.
By dividing the particle size distribution into equidistant intervals in a two-dimensional direction, the initial measured values are obtained and then fitted and interpolated. Combined with the particle size probability distribution coefficient, the particle size probability distribution in three-dimensional space is determined, and a general software algorithm is used for correction.
It enables accurate measurement of particle size distribution in non-dispersed samples, reduces costs and measurement errors, and is applicable to both spherical and non-spherical particles.
