A general model is suggested for the kinetics of clustering processes. It is considered that cluster species are composed of units of specific composition. Arbitrary combinations occur between the species. The association rate constant depends on the cluster size and the structural feature. The dissociation rate constant mainly depend on the number of bonds broken during dissociation. Thus the small fragments are easier to be cleavaged. The master equations for the kinetic model are given. They can be used for the numercial calculation of the cluster distribution at various time. Finally, the clustering processes during laser ablation and arc discharge are discussed.
