摘　　要：从碳纳米管中Kondo效应的影响出发,在有限温度下采用Anderson模型表征碳纳米管/磁杂质系统,利用Landauer公式对磁杂质碳纳米管的电导和热电势进行研究,得出和实验结果一致结论.Based on the influence of Kondo effect in carbon nanotubes, the Anderson model was used to characterize the system of carbon nanotubes/ magnetic impurity at a finite temperature. The electric conductivity and the thermopower in the system of carbon nanotubes/ magnetic impurity were researched by using the Landauer formula. The results of theoretical calculation agree well with that of experimental research.
