Pulsar glitches are the sudden increase in their spin frequency, most accompanied with a long timescale recovery process. A permanent shift would be remained in the first order derivative of spin frequency with time. Relevant data fitting research about this persistent shift was performed in this essay, we have found a more suitable fitting strategy by choosing a fitting function form kln(ax + b) and demonstrated that would be more meaningful in pure mathematical aspect in describe the correlation between the time scale of Delayed-Spin-Up τd (so as the persistent shift Δνp) and glitch size Δν.Some possible physical ideas about this fitting also have been presented while the clear physical mechanism behind this strategy still remain unknown.
