在de Sitter引力规范理论模型的基础上，提出了一个新的暗能量引力模型。在该模型中，除了宇宙常数外，均匀各向同性的挠率及其与曲率的耦合对暗能量起着重要的作用。这个模型可以提供宇宙从减速膨胀到加速膨胀的自然过渡。
A new gravitational model for dark energy is presented based on the model of de Sitter gauge theory of gravity. In the model, in addition to the cosmological constant, the homogeneous and isotropic torsion and its coupling with curvature play an important role for dark energy. The model may supply the universe with a natural transit from decelerating expansion to accelerating expansion.
