摘　　要： 在中子星表面磁场起源于自旋的有序极化的假定下,利用后牛顿挠率近似.由于挠率对自旋进动影响是坐标相关的,这将导致中子星磁场的变化,计算结果表明:脉冲星磁场倾向于转动方向,其演化尺度是10~6年至10~7年.在初始磁倾均匀假定下,我们得到的脉冲星磁倾角分布与天文观测分布和理论统计分析完全符合.本文是自脉冲星发现以来首次给出的磁场演化模型,也是为引力规范理论提供的首次间接证据. Under the assumption of Neutron star's surface magnetic field originated from the net Polarized spin of neutrons,the post-Newtonian approximation is used.Since the spin motion arised from torsion is coordinate dependent, which influences the change of magnetic field of Neutron star.The calculating conchtsions are:the magnetic field of pulsars inclines to its rotating direct- ion at the age of 10~6-10~7yr.Under the assumption of initial magnetic inclin- ation is homogeneous,we get the distribution of Pulsars inclination is in good agreement with the astronomy observational distribution and the theoretical statistics analysis.This paper gives the first magnetic field evolution mould, since the discovery of pulsars,and it's also the first direct evidence presented by the gravitational gauge theory.
