摘要: 本文研究的是Scalar-tensor引力理论中暗能量模型在宇宙不同时期的演化行为。我们对这种超出广义相对论框架的暗能量模型的特征进行了推导和分析，并比较了它和广义相对论框架下单标量场暗能量模型的差别。最后，我们在现有观测数据的限制下选取了其中的一类模型进行了数值计算，得到了在广义相对论框架下，普通的单标量场暗能量模型难以得到的物理图像。
Abstract: In this paper, we aim to discuss the evolvement of the dark energy that is assumed to be in the Scalar-tensor gravity. We derive and analyze the characteristics of this kind of dark energy model which exceed the general relativity framework, and compare the difference between the Sca-lar-tensor dark energy models and the general dark energy models. At last, with the current observational constraints, we choose a special model from the Scalar-tensor models to get the nu-merical calculation, and obtain results which is difficult for the general single scalar field model in the general relativity framework.
