How to Interpret a CDF

A CDF is interpreted in the same way as a CLD or an IDF. All these functions exhibit the probability distributions of domain size and arrangement. Clearer than a CLD is the IDF, because it does not contain an orientation average but exhibits the topology in a selected direction. Clearer than an IDF is the CDF, because it visualizes the nanodomain topology in space, i.e., in more than one direction. 

The results of these considerations are readily extended from cylinders to lamellae in the latter case the strong triangular peaks are wider, but closer to each other. 

Arrangement of Particles and the Corresponding Peaks. If a CDF shows only positive peaks, the particles in the material are distributed at random . There is no arrangement. Growing correlations are indicated by one or more triplets of peaks 

From a practical point of view the sign of a peak in CLD, IDF, or CDF is described by the character of surface contact between particle and ghost if they contact each other in the normal way, the peak is positive it is negative if they penetrate each other at the considered surface. Thus, positive peaks describe the size of par-
