Generic three-phase systems of types I and II, described in detail in the Introduction. (a) The type I structure is shown on the left: region 2 is embedded in region 1. The sample consists of a macroscopic number of these spatially uncorrelated structures, which are embedded in a solvent or solid matrix (right). The number of objects 1 and 2 is equal and hence their concentrations over the sample coincide. (b) The type II structure: regions 1 and 2 do not overlap and their positions are uncorrelated in the sample. The concentrations of objects 1 and 2 are different in general. |
