| Abstract: | The radio luminosities of pulsars are given as functions of their period and the time variation of the period. The parameters
of that dependence are calculated and independent distances are determined for pulsars. The average electron densities toward
the pulsars are determined from the known dispersion measures. The results obtained are used to study the large-scale electron
density distribution in the Galaxy. The distribution maximum lies in the vicinity of the Sagittarius spiral arm. The electron
density falls off exponentially in the regions between spiral arms.
