依据介观物理学的基本概念、半经典电子输运理论和碳纳米管的电子结构，对非掺杂直状金属型单层碳纳米管（ＳＷＮＴｓ）的电导特性进行理论研究，计算表明；ＳＷＮＴｓ的电导是量子化的．
According to the fundamental concept of mesoscopic physics, semi-classical electronic transport theory and the electronic structure of carbon nanotube, the conductance property of undoping metallic single-wall carbon nanotubes(SWNTs) was studied theoretically. Calculations show that the conductance of SWNT is quantized.
