摘要

We examine the theory of generation order parameters.Three kinds of generation order parameters are introduced, which describe the production of high-energy y photons in a cascade process scenario.We find acorrelation between the average power-law photon index Г and spin-down rate P in 38 common FERMI -γ-raypulsars, and find that the third generation order parameter, which implies that the magnetic field may have themost significant effect on the higy-energy γ photon absorption in the cascade processes, is the best one.Thestatistical work shows that the theory of generation order parameters can be applied to describe the the -y-raypulsar radiation mechanisms in the cascade processes.
