AbstractWe study the properties of the heavy-element absorption systems and their evolution with redshift based on the distribution of the free paths (FPs) of the light rays which come from QSOs and are intercepted by absorbers. We find that the mean free path (MFP) regularly varies with the cosmic time and has a definite periodic component, which shows a marked evolution of the absorbers. For the MFP calculated by the catalog of the absorption-line redshifts of Junkkarinen et al. (1991), an useful fitting function is
