DOES THE RADIO LUMINOSITY OF PULSAR GROW UP IN ITS LATER STAGE?

In usual statistical analyses, because of diversities of proper parameters of pulsars, some interesting features might be smeared. In order to remove these diversities, we use the mean values for all quantities of pulsars, instead of values of individual one to do statistical analyses. Logp/p³- log τ and LogL-log τ have been plotted. The most interesting feature is that the radio luminosity of pulsar evidently appears to regrow up after its initial dropping. This feature is difficult to understand in usual models. Two tentatlive interpretations have been given.
