随机分布多分散重叠球模型
The model of randomly distributed polydisperse overlapping spheres
摘要：
随机分布的不同半径的重叠球的模型来描述一个非均匀的多孔介质。计算了介质空间中不同半径孔隙相对位置的双粒子关联函数，并进行了详细的分析。该模型允许表征无序多孔介质的最近邻居的数量，所有的口连接孔隙与相邻孔隙的面积。这些参数除了取决于比表面积、孔隙率、逾渗阈值和孔径分布函数外，还取决于孔径和孔隙率。
英文摘要：
A model of randomly distributed overlapping spheres of different radii is represented to describe a heterogeneous porous medium. Two-particle correlation function of the relative position of pores of different radii in the medium space was calculated and detailed analysis was carried out. The model allows to characterize the disordered porous medium with the number of nearest neighbors, the area of all mouths that connect pore with the neighboring pores. These paramaters depend on the pore size and porosity and --- in addition to the specific surface area, porosity, and percolation threshold and the distribution function of pore size.
