A Note on the Anti-glitch of Magnetar SGR 1935+2154

The magnetar SGR 1935+2154 is reported to have an anti-glitch,accompanied by fast radio bursts,and transient pulsed radio emission.In the wind braking model,this triplet event tells people that(1) SGR 1935+2154 does not have a strong particle wind and can be approximated by magnetic dipole braking in the persistent state;(2) its antiglitch is due to an enhanced particle wind,similar to the first anti-glitch in magnetars;(3) its transient pulsed radio emission may be due to a decreasing emission beam during the outburst;(4) the enhanced particle acceleration potential and pulsar death line may not be the dominate factor.
