内容	Rapid fluctuation with a frequency dependence of 1/f (with ' 1-2) is characteristic of radiationfrom black-hole objects. Its origin remains poorly understood. We examine the three-dimensional mag-netohydrodynamical (MHD) simulation data, finding that a magnetized accretion disk exhibits both 1/ffluctuation (with '2) and a fractal magnetic structure (with the fractal dimension of D1.9). The frac-tal field configuration leads reconnection events with a variety of released energy and of duration, therebyproducing 1/f fluctuations.
