Research results indicate that the pore geometry of the rock and soil shows the fractal behavior over the range from atom scale to grain size.

大量的研究表明，岩土介质的孔隙几何从原子尺度到晶粒尺寸范围内均表现出分形特征。

The macroscopic properties of the rock are associated with its microstructure parameters by the model in which the parameters reflect the pore-size distribution and microstructure characteristics.

该模型将介质的微观结构参数和宏观性质相联系，其中的参数反映了介质的孔隙特征和结构特征。
