heal.abstract	This work deals with a detailed study of the multiplicity of relaxation times of the dielectric relaxation of water molecules in dispersed ice microcrystals at different stages of evolution with time, by means of the thermally stimulated depolarization (TSD) current method. Independently of the stage of evolution, the relaxation mechanism is multiple due to a continuous distribution of both the activation energy W and the pre-exponential factor τ0. A linear relationship exists between W and ln τ0, the socalled compensation law. With advancing evolution the distribution becomes broader, while the relaxation process becomes faster. The compensation temperature is, on the contrary, independent of the stage of evolution. Some aspects of the dielectric-relaxation mechanism in ice emulsions are discussed in the light of these results. © 1987 Società Italiana di Fisica.	en
