Some Statistical Analysis about Radiant Characters and Space Distribution of Pulsars

Using the catalogue of 330 pulsars,further disscussions are made about the problem of the evolutional regularities of some important characters of pulsars in this paper.The main results are as follows.1.With the increasing of age,the energy loss rate Ė,radio luminosity L_R,magnetic energy and angle of the radiational cone decay rapidly.It indicates that the energy and radiation of pulsars gradually decrease.2.The radio transformation efficiency increases with age t.This shows that the maximum value of the frequency spectrum of radiation of pulsar evolves toward the radio wave band gradually.3.The distance from Galactic plane|Z|increases with age.This means that probably pulsars are migrating away from the plane.
