It is shown that the multifractal spectra of GSR are obviously different in inter- and intra- plate regions. Moreover, though Japan and New Zealand are all located at the boundary of plates, West and East China are all characterized of continental tectonic structure, the multifractal spectra of GSR for both the two regions are also different. Further analysis shows that the natures of multifractal spectra of GSR are somehow related to the complexity of tectonics.展开更多

The multifractal analyses for three films were made using height from a depth of thickness of film B and q from 55 to -55. The scale- invariance is very good for all lncq(e)~lne plots and t(q)~q plots at least close to three orders of magnitude. But the multifractal spectra f(a) of the films are quite distinct due to their different height distribution.展开更多
