一般的凝聚态系统由于自由度众多，很难精确求解。因此针对具体的凝聚态系统，采取各种近似，建立不同模型，是目前凝聚态理论研究的主要手段。本论文以晶体中的电子模型为例，讨论了四个在凝聚态领域的研究和计算中常用的理论模型。

Condensed matter systems with many degrees of freedom, it is difficult to calculated precisely. So for specific system of condensed matter, take all kinds of approximation to establish different models, is a major means of condensed matter theory research. Crystals in electronic model, for example, this paper discusses the four research in the field of condensed matter and the theoretical model is commonly used in computing.
