Heterogeneous condensation on several types of centers in dynamic   conditions
  A system of a metastable phase with several sorts of the heterogeneous centers is considered. An analytical theory for the process of condensation in such a system is constructed in dynamic conditions. The free energy of formation of the critical embryo is assumed to be known in the macroscopic approach as well as the energy of solvatation. The recurrent procedure of the establishing of the characteristic times and lengths is presented. The semiempirical method of the description of the period of essential formation of new phase embryos on the heterogeneous centers of some sort is given.
