摘要
Based on the hypothesis that in all states of flux (including demographic flux), as in all liquids, the phenomenon of cavitation appears when the local (or demographic) pressure decreases below the vaporization value (the demographic point of survival) respectively, under the saturation pressure (defined by the fertility rate), at the given temperature of gases (general demographic conditions), dissolved in the liquid. This paper presents and analyses cavitation phenomenon as a powerful, rather than merely a potential, demographic model. The structure of this paper could be considered as a succinct three-section solution to describe the evolution from the demographical explosion of the entire world to the demographical implosion of the whole of Europe during the next three or four decades, in a number of population trends. Some final remarks underline the importance of cavitation model and its applied version in demographic implosion, as well as evaluation of the risk of cavitation and computation of cavitation coefficients in demography.
