摘要
We consider a generalized quintom （GQ） dark energy model for changing the equal weight of the negative-kinetic scalar field （phantom） and the normal scalar field （quintessence） in quintom dark energy. Though the phantomdominated scaling solution is a stable late-time attractor, the early evolution of GQ is different from that of the quintom model and the adjustability of the dark energy state equation in the model is improved.
