For the strongly correlated electron systems, we constructed more accurate effective models and investigated physical properties quantitatively. In particular, we focus on the rare earth materials which are well known as the typical strongly correlated systems. Some physical quantities were calculated based on the constructed effective models. The obtained results were in good agreement with the experimental ones. We could propose the quantitative theoretical method to study the strongly correlated electron systems.

对于强关联电子系统，我们构造了更精确的有效模型，并定量研究了其物理性质。特别地，我们将重点放在稀土材料，这是众所周知的典型强关联系统。根据所建立的有效模型计算了一些物理量。所得结果与实验结果吻合较好。为强关联电子系统的研究提供了定量的理论方法。
