英文摘要	We model the evolution of the magnetic fields of neutron stars as consisting of a long term power-law decay modulated by short term small amplitude oscillations. Our model predictions on the timing noise <(nu)double over dot> of neutron stars agree well with the observed statistical properties and correlations of normal radio pulsars. Fitting the model predictions to the observed data, we found that their initial parameter implies their initial surface magnetic dipole magnetic field strength B-0 similar to 5 x 10(14) G when t(0) = 0.4 yr and that the oscillations have amplitude K similar to 10(-8) to 10(-5) and period T on the order of years. For individual pulsars our model can effectively reduce their timing residuals, thus offering the potential of more sensitive detections of gravitational waves with pulsar timing arrays. Finally our model can also re-produce their observed correlation and oscillations of <(nu)double over dot>, as well as the "slow glitch" phenomenon.
