摘　　要：综述了纳米金丝电导量子效应的基本概念,介绍了金丝电导研究背景及现状,并从理论上分析了电导量子效应的机理。介绍了用STM和MCBJ等工具对纳米金丝的原子基链进行的研究。纳米金丝原子基链的电导是量子化的,量子电导受到包括电场、磁场、温度等各种因素的影响。在综述的基础之上,提出了该领域未解决的科学问题并指出了该领域未来的发展方向。The basic concept of quantum properties of gold nanowire was presented in this paper. The research background and the present situation is introduced, and the mechanics of conductance by theory is analyzed. The research of the nanocontact of gold wire by STM and MCBJ is also introduced. The conductance of nanocontact of gold wire is quantum, and the quantum properties is under the influence of the electrical field, magnetic field and temperatures, et, al. On the base of experiment results, the unsolved scientific problems are pointed out and the future development direction of this field is predicted.
