\n\u984c\u76ee: Multifractal multiscale intermittency
\n in fully developed turbulence<\/p>\n
\u6982\u8981\uff1a We consider a question of multifractality based
\n on an extended self-similarity that depends on scale.
\n We look into this concept of a multiscale multifractality
\n in the context of scaling properties of intermittent
\n turbulence in space plasmas. We analyze time series of
\n plasma parameters of the slow and fast speed streams of
\n the solar wind plasma measured in situ by Helios 2 and
\n Advanced Composition Explorer spacecraft during solar
\n minimum and maximum. To quantify scaling of this turbulence,
\n we use a generalized weighted Cantor set with two different
\n rescaling parameters describing with various probabilities
\n nonuniform intermittent multiplicative process of distribution
\n of the kinetic energy between cascading eddies of various sizes1.<\/p>\n
We show that the universal shape of the multifractal spectrum
\n results not only from the nonuniform probability of the energy
\n transfer rate but also from the multiscale nature of the cascade.
\n It is worth noting that only in the case of the two-scale cascade
\n one can reproduce the entire experimental multifractal spectrum,
\n especially for the negative index of generalized dimensions2.
\n It appears that intermittent pulses are stronger for the model
\n with two different scales, where the singularity spectrum is often
\n asymmetric3. Therefore, we argue that there is a need to use the
\n multi-scale cascade model. Hence we hope that our new more general
\n asymmetric multifractal model could shed light on the nature of
\n turbulence and we propose this model as a useful tool for analysis
\n of intermittent turbulence in various environments.<\/p>\n
