In the present paper we shall consider that the HII complexes observed in galaxies may be interpreted as the resulting Strömgren volume produced by a cluster or association of exciting stars. If ρH is the density of the hydrogen surrounding the cluster or association and I the number of ionizing quanta (λ < 912 å) emitted by the stars, the ionized volume becomes
