In this paper the problem of the evaluation of the grain-size distribution of a spherical material embedded in a matrix is studied and a solution, based upon the measured distribution of the intercepts upon a random line cut off by the particles, is developed.
There are no limitations on the method, with respect to the type of particle-size distribution involved and, in theory, the grain size distribution may be established to any desired degree of accuracy by the use of a conversion table.
Conversion tables, sufficiently comprehensive for many practical purposes, are provided and the necessary calculations involve only a knowledge of multiplication and addition.
The work suggests that the method based upon the measurement of intercepts is experimentally simpler than is the case when the diameters of the circular intersection figures are measured. Furthermore, since the conversion tables contain fewer terms than is the case for measurements based upon diameters, the labour of application is much less than in the method based upon the measurement of the diameters of the intersection figures.
