Each component of an assemblage, whether of subject or isolates is called Phase , and the bond or relation of the components is called Phase relation. The well-defined concept of distinctive phase relations and their notational representations have enabled CC to assign homonym-free specific class numbers to complex subjects and complex isolates , indicating their phase relations.
