The shear moduli of single-walled carbon nanotubes(SWCNT) are investigated by using energy theory.
利用能量方法研究了单壁碳纳米管（SWCNT）的剪切模量。

Based on the principle of molecular mechanics, the total system potential energy of SWCNT, subjected to torsion only, is obtained.
基于分子力学的原理，系统总势能的单壁碳纳米管，进行扭转唯一，被获得。

As the effect of external perturbation of SWCNT rope, a pseudogap of about 0.1 eV at the Fermi level appears, and it makes a deep valley in the transmission probability curve.
