SOME FEATURES IN THE DISTRIBUTIONS OF PUL SAR PARAMETERS

The distributions of a number of parameters of 558 known pulsars are a nalyzed. The period distribution reveals the presence of two pulsar gr oups (with periods P greater than or equal to 0.1 s and P < 0.1 s) dif fering in evolution. There are no objects at distances larger than z = 700 pc from the Galactic plane among the pulsars with P < 0.1 s that are not members of globular clusters. At the same time, a few dozen lo ng-period pulsars have z = 1 - 2 kpc, corresponding to kinematic ages more than 10 Myr. A high correlation between luminosity and power of l osses due to magnetic-dipole radiation (L proportional to(3) root W-md ) is observed. The constructed luminosity function shows that no pulsa rs md with L < 10(26) erg s(-1) appear to be present in the Galaxy. Th e total number of active Galactic pulsars reaches 2.4 x 10(5), corresp onding to a pulsar birthrate of order one object every 40 yr.
