英文摘要We find that the expansion of the universe is accelerating by analyzing the recent observation data of type Ia supernova ( SN- Ia). It indicates that the equation of state of the dark energy might be smaller than - 1, which leads to the introduction of phantom models featured by its negative kinetic energy to account for the regime of equation of state parameter w < - 1. In this paper the possibility of using a non- minimally coupled real scalar field as phantom to realize the equation of state parameter w < - 1 is discussed. The main equations which govern the evolution of the universe are obtained. Then we rewrite them with the observable quantities.
