Popis: The existing models describing growth rate dispersion don't consider a healing process of crystal damages or surface defects. In this paper a model is presented which takes into account such a healing process. With regard to the new model formulas, characterizing the crystal size distribution, are derived from the population balance and discussed. The considerations are extended to continuous crystallizers. Les modeles existants qui decrivent la dispersion des vitesses de croissance ne tiennet pas compte d'un processus de guerison de cristaux endommages ou de defets de surface. Dans la publication presente un modele es presente qui tient compte d'un tel processus de guerison. En consideration du noveau modele des formules characterisant la distribution de la grandeur des cristaux sont derivees du bilan de population et ensuite discutees. Les considerations sont etendues aux cristalliseurs continus.
