Renormalization-group equations are solved to study phase diagrams of nearly-half-filled one-dimensional conductors interacting with phonons. A spin-gap charge density wave phase exists between a gapless density wave phase and a spin-gap superconductor phase. On-site and intersite electron-phonon couplings show large differences near half-filling in the presence of on-site electron repulsion.
