对磁星雨燕J1822.3-1606的不同授时结果进行了理论分析和理解。需要注意的是，不同的定时解决方案不仅由定时噪声引起，还因为在突发之后周期导数减小。减小的周期导数和较大的定时噪声都可能源于与磁星有关的风制动。SWIFT J1822.3-1606的未来时间将有助于澄清其周期导数是否随着时间的推移而减少。
The different timing results of the magnetar Swift J1822.3–1606 are analyzed and understood theoretically. It is noted that different timing solutions are caused not only by timing noise, but also because the period derivative is decreasing after the outburst. Both the decreasing period derivative and the large timing noise may originate from wind braking associated with the magnetar. Future timing of Swift J1822.3–1606 will help clarify whether or not its period derivative is decreasing with time.
