《周易》本经卦爻辞的研究是易学研究的前沿课题之一。本文充分利用新出土文献资料及其相关成果，以卦爻辞的考释为主要任务，同时根据考释活动所获得的一系列新见解，来探索并提炼《周易》本经文本的新解释体例。在研究的基础上，完成《周易》本经简帛及传统文献的异文汇校。在研究方法上，坚持出土文献与传世文献的双重互证，立足于字词文例研究和卦义释例研究的相互结合。这五组卦爻辞分别代表了卦爻辞的五类解释方式。第一类是单条材料的新证，选择了三条材料。《旅》卦初六爻辞的“取灾”当读为“取与”，这一发现得之于简帛文献的文例对照分析。《兑》卦辞当据帛本补出“小”字，九五爻辞“孚于剥”其实是“名词+于+动词”的被动句式。《屯》六三爻辞的“君子几”当训为“君子危”，这一新解得之于“不如”的句法分析和训诂。第二类属于特殊语汇的贯通考释，本经“小”字句读及其语义功能的重新发现，引起一系列卦爻辞的重新解释，给本经卦义研究、易例研究带来一定影响，也以此深入把握了本经特殊语汇诸如“亨”、“贞”、“有悔”、“有言”的语义性质及其功能。第三类属于思想概念的类证分析，通过对《坎》卦辞“维心”、《益》九五“惠心”、《随》上六爻辞“维之”的考释，认为它们是本经“心”义最重要的三条材料，共同体现了周初“维心”的民本思想。第四类属于单卦卦义的考释分析，以《丰》卦为案例，考察本经每卦的卦爻辞之间具有内在统一的语义特征。第五类属于传统的注释方式，选择本经十八卦的文本给予了新校释，这类注疏体的特点是多于综合吸收，少于批评辨析。通过以上这一系列的新释，归纳概括出《周易》本经文本两条重要的解释体例。（1）对于卦爻辞的考释来说，文献语言是基础与核心，它由四个语义要素组成：物象、事类、说理辞和判断辞（断辞）。（2）语义自洽性，即卦内各条卦爻辞的语义是有完整的语义结构和句内逻辑。这条两条体例直接决定了卦爻辞的性质，即：卦爻辞具有说理性；本经文本具有思想性质。

Since the early twentieth century, the newly unearthed documents have provided a great deal of raw materials about Zhouyi, which has produced a far-reaching effect on the research of Zhouyi. The research of Gua Yao Ci of the original Zhouyi is one of the frontier projects in this field. This paper mainly focuses on the textual research of Gua Yao Ci with the deployment of these materials and their relative research findings. And at the same time, in light of a series of new ideas obtained in the process of the textual research, this paper explores and refines the styles of the new explanations of original Zhouyi texts, in the hope of due contributions to the researches of Zhouyi and the history of Chinese ideology. On the research basis, this paper completes the collection and collation of different Zhouyi characters, the systematic collation of the materials of Zhouyi noted and quoted in Han and Tang Dynasties and the comprehensive carding of references to the different characters of Gua Yao Ci in the modern notes of Zhouyi. As for the research method, this study holds the double mutual proof of unearthed documents and ancient documents, based on the combined study of character examples and the explanatory examples of the meanings of divinatory symbols, and this paper also completes the collations and explanations of the total sixty-four Gua of Zhouyi. In light of the above studies, it chooses and refines the new explanations of five pairs of Gua Yao Ci, from which comes the generalization of the styles of new explanations attained.With the above new explanations, this paper conducts the induction and generalization of two explanatory styles of Zhouyi texts. （1）The new idea of the textual compositon of the Zhouyi, which consists of three basic parts: document language, semiotic language and textual forms. As for the textual research of Gua Yao Ci, document language is the basis and core, which is composed of the following four semantic elements: object image, matter, reasoning and deducible. （2）Semantic self-consistency, which means the semantics of each Gua Yao Ci has complete semantic structure and sentential logic. The above two rules of styles directly determines the nature of Gua Yao Ci, namely Gua Yao Ci has inferior reasons and Zhouyi texts has ideological contents.
