We consider a simple model of a quasi-one-dimensional conductor in which two order parameters (OP) may coexist, i.e., the superconducting OP delta and the OPW that characterize the amplitude of a charge-density wave (CDW). The considered model can be applied to high-Tsubc superconductors where the parts of the Fermi surface near the "hot" spots may be regarded as the considered two Fermi sheets. We also discuss relation of the considered model to the simplest model for Fe-based pnictides.
