摘要：

We show that the persistent offset in the spin-down rate of the Crab pulsar following the 1975 glitch is difficult to explain by the usually assumed dynamic coupling between the crust and the superfluid interior. One explanation of the observed behavior is an increase in the external torque caused by a rearrangement of the stellar magnetic field.
