The volume-weighted/volume-number mean particle diameter of the ingredient is applied to the equation of Johnson (1972) as a measure of the mean particle size defining the degree of homogeneity of random mixtures. By introducing the volume shape factor, the applications of this equation are extended to ingredients of nonspherical particle shape.
将该成分的体积加权/体积数平均粒径应用于约翰逊(1972年)的方程,作为定义随机混合物均匀度的平均粒径的一种度量。通过引入体积形状因子,该方程的应用扩展到了非球形颗粒形状的成分。
