Abstract: | We give some details about the periodic cylindrical
solution found by Zhang and Ou-Yang in 1996 {\em Phys. Rev.} E {\bf
53} 4206] for the general shape equation of vesicle. Three different
kinds of periodic cylindrical surfaces and a special closed
cylindrical surface are obtained. Using the elliptic functions
contained in \emph{mathematic}, we find that this periodic shape has
the minimal total energy for one period when the period--amplitude
ratio $\beta\simeq1.477$, and point out that it is a discontinuous
deformation between plane and this periodic shape. Our results also
are suitable for DNA and multi-walled carbon nanotubes (MWNTs). |
