%X The stabilities of one-dimensional conducting polymer chains with finte lengths have been studied in the frame work of the SSH tight-binding model.Three kinds of boundary conditions have been proposed to stabilize the dimerized structure of the chains.It was found that the natural boundary condition or the end-fixed boundary condition is applicable for getting a result to fit the observed photo-absorption of polyacetylene with short (N<20) lengths.
