Many values of the observed conductivity percolation exponent t cannot be explained by the classical universal theory or by the existing nonuniversal theories. In particular, the 1.3≤t≤4.0 clustering of t values, in both composite materials and porous media has not been accounted for. In this work we were concerned with a pseudononuniversal percolation behavior that, unlike the genuine nonuniversal behavior, explains the statistics of the experimentally observed percolation conductivity exponents in continuum systems.
许多观测到的电导率逾渗指数t的值无法用经典通用理论或现有的非通用理论来解释。特别是，复合材料和多孔介质中t值在1.3≤t≤4.0范围内的聚类现象尚未得到解释。在这项工作中，我们关注一种准非通用逾渗行为，与真正的非通用行为不同，它解释了连续介质系统中实验观测到的逾渗电导率指数的统计情况。
