摘要
Crab-like supernova remnants (plerions) are a kind of SNR which has a central neutron star or pulsar. It is generally believed that the central pulsar drives the evolution of the plerion. A statistical relation between the soft X-ray (0.2—4 keV )luminosity L_x of the synchrotron nebula (including the pulsar)and the pulsar rotating energy loss rate
