摘　　要：本文根据Ｒ－Ｓ模型讨论脉冲星的γ辐射，在讨论光子被电磁场吸收时，我们把中子星磁层分成两部分，一部分以电场吸收为主，另一部分以磁场吸收为主。本文以电子在电磁场中的级联过程为基础，计算了Ｃｒａｂ、Ｖｅｌａ等六个已知γ射线脉冲星的一些物理量，发现与观测基本相符。另外我们还预言了一些很可能是γ射线脉冲星的候选者。We calculate the γ-ray emission from pulsars based on the R-S model.We divide the magnetosphere of the neutron star into two parts,in one part the photons are absorbed by the electric field and in another the photons are absorbed by the magnetic field.According to the cascade process,we calculate some quantities of γ-ray pulsars and compare it with the observation,we find that the theoretical results are in agreement with the observation and we predict that some pulsars may beγ-ray pulsars.
