| 摘 要： | 本文讨论了脉冲星磁偶极辐射模型所取得的成就和存在的困难，针对不足之处对磁偶极模型进行修正。从统计上得到修正因子与周期变率的幂律关系。由修正后的磁场强度得出其衰减时标大于１０８年，这与有关的理论研究结果一致。修正后的磁偶极模型给出周期变率和周期的新关系为р∝Ｐ－３，这恰好和р－Ｐ图中加速线以上的资料的统计拟合方程一致。

| Abstract: | The successes and shortcomings of the magnetic-dipole emission model for pulsars are reviewed here and a modification of this model is presented. There is a power law relation between the modificatory factor and the time derivative of the period. The decaying time scale of the modified magnetic field is greater than 108 years which is consistent with the theoretical results.The new relation between P and P derived from the modified model is, which is similar to the result of the statistical analysis. |
