变导的

Amukhin et al.,and convert it into an effective1D chain with particular distribution of equivalent coupling bonds.Then we use the single-electron Schrodinger equation to calculatewave functions of electrons in the chain by transfer matrix method,without using the assumption of Samukhin et al.On variable hoppingmechanism and critical percolation condition.From this calculationwe obtain the dc conductance directly from Landauer-Buttikarformula.

mukhin提出的多层次等级分形结构模型，将其简化为耦合键强度t具有特殊分布的等效一维链，舍弃前人假设的变程跳跃机制与临界渗流条件，从单电子薛定谔方程出发，用转移矩阵方法计算一维链的透射系数，再利用Landauer-Buttickar公式直接求出直流电导。
