[Abstract]:The braking mechanism of neutron stars is a basic problem in the study of neutron stars. The magnetic dipole radiation model shows that the braking index of the neutron star is 3, and the braking index of all the observed neutron stars is less than 3, which indicates that there are other rotational energy loss modes in the neutron star besides the magnetic dipole radiation. The loss of rotational kinetic energy of neutron star is considered from magnetic dipole radiation, particle flow escape caused by unipolar induction and energy loss caused by neutron star and quantum vacuum friction. Based on these three radiation mechanisms, the improved formula for calculating the energy loss power of neutron stars and the dependence of the period on the first derivative of time and the period are given. The relationship between the first derivative of cycle, braking index, surface magnetic field intensity and magnetic dip angle of six neutron stars J1119, 6127, B1509, 58J 1846, 0258N, B0531, 21C, B0540, and B0833, 45) has been investigated. The results show that in the star-wind effect, when the potential difference of vacuum gap is constant, the magnetic inclination can only be obtained in a limited range, while in other cases, the magnetic inclination can be determined continuously in the range of 0 ~ 90 擄.
