The specific heat of the super carbon nanotube (ST) was investigated by the molecular structure mechanics method. At given temperature, it was found that the specific heat of the ST is a fixed value and is almost independent both of the length, diameter and of chirality of the ST. By comparing the influences of the chirality of the ST on its mechanical properties, electronic properties and thermal properties as well, we find that the chirality effects on the physical properties of STs can be neglected. This result may be regarded as a universal law for the physical properties of STs. (C) 2008 Elsevier B.V. All rights reserved.
