摘      要：The different timing results of the magnetar Swift J1822.3—1606 are analyzed and understood *** is noted that different timing solutions are caused not only by timing noise,but also because the period derivative is decreasing after the *** the decreasing period derivative and the large timing noise may originate from wind braking associated with the *** timing of Swift J1822.3—1606 will help clarify whether or not its period derivative is decreasing with time.
