We have studied the transport properties of disordered one-dimensional two-bandsystems. The model includes a narrow d band hybridised with an s band. The Landauerformula was used in the case of a very narrow d band or in the case of short chains. Theresults were compared with the localisation length of the wavefunctions calculated by thetransfer matrix method, which allows the use of very long chains, and an excellent agreementwas obtained.
