We explore possible effects of a magnetar burst on the radio, X-ray, and gamma-ray flux of a pulsar wind nebula (PWN). We assume that the burst injects electron-positron pairs or powers the magnetic field and explore the total energy at injection and the spectral index needed in order to increase the X-ray flux by about one order of magnitude, as well as its decay time until reaching quiescence. We also explore magnetically powered phenomenology that could explain a temporary increase of the PWN synchrotron emitted flux and perhaps the relatively common lack of PWNe surrounding magnetars. This phenomenological study is of interest for fast radio bursts (FRBs) as well, given that the connection between magnetars and this kind of systems have been recently established observationally.

我们探索了磁脉冲爆发对脉冲星云（PWN）的无线电，X射线和伽马射线通量的可能影响。我们假设该脉冲串注入电子-正电子对或为磁场供电，并探索注入时的总能量以及使X射线通量增加大约一个数量级所需的光谱指数，以及其衰减时间，直到达到静止状态。我们还探索了磁动力现象学，该现象可以解释PWN同步加速器发射通量的暂时增加，以及可能相对普遍缺乏的PWNe周围的磁星。这种现象学研究也对快速无线电脉冲串（FRB）感兴趣，因为最近在观测上已经建立了磁星与这种系统之间的联系。
