摘要：

We consider the multifractal spectra of fluctuations of the interplanetary magnetic field strength before and after shock crossing by Voyager 1 near 85 and 95 AU from the Sun, correspondingly. We show that the multifractal scaling of magnetic fields is asymmetric in the outer heliosphere, in contrast to the symmetric spectrum observed in the heliosheath. Moreover, we show that the degree of multifractality of the solar wind before shock crossing is greater than that in the heliosheath, where the turbulence may become roughly monofractal.
