Microfracturing processes of sandstone and Oshima granites soakedin air, water, chemical solutions DTAB and PEO, have nonlinearevolution properties. Their temporal fractal properties vary assoaking environments. At most of cases it seems to be possible todefine two or three fractal subranges (multi fractal structure).Whatever variations are present in fractal properties (from a singlefractal structure to multi-fractal structure with D_l > D_2 or D_l 展开▼
