In this paper, we shall calculate the Boltzmann conductivity in the k·p scheme and explore effects of AB flux on transport properties of nanotubes in the diffusive region. In §2, the k·p scheme is reviewed very briefly. Some examples of explicit results of the conductivity in the presence of flux are presented in §3 for impurity scatterings and in §4 for the electron-phonon scattering, demonstrating a possibility to directly determine a small gap present in metallic nanotubes experimentally. The results are discussed in §5 and summarized in §6.
