The rehybridization of electronic orbitals in carbon nanotubes

Rehybridization of electronic orbitals in carbon nanotubes contains tilting angles of \pi orbital, electrons wavefunctions of \pi orbital and \sigma orbital, degrees of hybridization, etc. In this paper, we have obtained analytical formulas of tilting angle of \pi orbital relative to tube surface, electrons wavefunctions of \pi orbital and \sigma orbital, degrees of hybridization, separately, as well as the numerical results.
