【 摘 要 】

This paper provides a method for judging growth or decay of the magnetic field of pulsar by using pulse period 𝑃, or frequency 𝑣, and its first and second derivatives $dot{P}$, $ddot{P}$ or $dot{v}$, $ddot{v}$. The author uses this method to judge the growth or decay of the magnetic field of Crab pulsar. The judged result for Crab pulsar is that the magnetic field of Crab pulsar is growing now, but it is not decaying. The result corresponds with the actual case of Crab pulsar.
