本文属于汉语学史的研究范围。论文以段玉裁的《说文解字注》为材料范围，以“本义”、“引申义”及“本义”“引申义”之间的关系为考察内容，以对“本义”进行“造意”“实义”二分和引申义有关理论为指导，全面分析《段注》“本义”、“引申义”，探讨段玉裁的“本义”观、“引申”观，并对“本义”“引申义”之间的关系进行梳理。第1章是本文的绪论部分。从目前学术界对《段注》的研究来看，“本义”的研究还相对比较薄弱，“引申义”的研究还有待深化，“本义”“引申义”之间的关系还有待于彻底清理。因此，我们有必要对《段注》中的“本义”“引申义”以及二者的关系加以考察分析。本文主要以“本义”及“引申义”的相关理论为指导，运用定量与定性相结合的方法、统计法、归纳法、比较法等研究方法，分4个步骤实现本文的预期目标。这一部分还对本文相关问题的研究现状进行了简要综述。第2章以《段注》中的“本义”为分析对象，考察其材料特点、与字形分析相贴切的程度、在文献中的使用情况等。经考察，不论是段玉裁遵从《说文》还是校改《说文》的字形分析，《段注》“本义”与字形分析都体现出高度的一致性；在“本义”的文献使用方面，段玉裁有些给出文献例证，有些没有，有些我们未能为其找到文献使用例。我们认为，《段注》“本义”实质就是字形义。在“本义”文献使用这一问题上，段玉裁“本义”并不要求一定要有文献例证。这就是段玉裁的“本义”观。第3章以《段注》中的“引申义”为分析对象，考察其材料特点、引申理据的情况、在文献中的使用情况等。经考察，《段注》的“引申义”内容比较广泛，并且能够给读者提供一定的引申理据。对于“引申义”文献使用的这一问题，段玉裁也没有一定要有文献例证的要求。这就是段玉裁的“引申”观。第4章以《段注》中“本义”“引申”同时出现的材料为分析对象，考察《段注》“本义”内部的各种关系、“本义”“引申义”之间正常关系与非正常关系等。“本义”“引申义”之间的正常关系从引申规律的角度对引申条目进行归类分析，非正常关系则要对各种关系进行归纳，以求对《段注》“本义”“引申义”的关系有一个全面认识。第5章是本文的结论部分。这一部分主要对《段注》在词义系统研究方面所做的贡献、“本义”“引申义”存在的问题进行总结。段玉裁在《段注》中使用了“本义”“引申”两个术语，并用大量的语言事实对其进行阐述与论证，而且提供了大量的“本义”“引申义”的文献材料。《段注》“本义”“引申义”毕竟不是现代意义上的概念，因此，我们应该区别对待段玉裁所讲的“本义”与“引申义”。最后是论文的结语部分，对整篇文章的结论进行总结。

This thesis belongs to the study of Chinese history. Based on the DuanZhu written by DUAN Yu-cai, this thesis mainly studies original meaning, extending meaning and their relationship with theories of the twos. So we can draw a conclusion of the twos, and thesis analyses their relationship.Chapter 1 is the introduction of this thesis. It is necessary for us to study on original meaning, extending meaning and their relation because of weak study on it. We handle materials on the base of theories of original meaning and extending meaning. And we achieve the objective by using four research methods such as Quantitative and qualitative combined method, statistical method, inductive method, comparative methods etc, and by four steps. Chapter 2 takes original meaning as the material, and studies its characteristics, the degree of the relation between original meaning and graphic analysis and using in the literature. We find that the relation between original meaning and graphic analysis shows a high degree of consistency. Therefore, original meaning in DuanZhu is the graphic meaning. And it is not necessary for original meaning to be used in literature. This is DUAN Yu-cai’s original meaning concept. Chapter 3 takes extending meaning as the material, and studies its characteristic, explanation of it and the using in the literature. We find that extending meaning is not the only content, and DUAN Yu-cai provided the explanation of extending meaning definitely. It is not necessary for extending meaning to be used in literature. This is the extended concept.Chapter 4 studies the relationship between original meaning and extending meaning including normal and abnormal relationship。The normal relationship is analyzed from aspect of regulation, and the abnormal relationship is concluded. So we can have a comprehensive understanding of the relationship between original meaning and extending meaning.Chapter 5 is the conclusion of this thesis. This part makes a conclusion of contribution of DUAN Yu-cai in the study of meaning’s system and provides the questions of original meaning and extending meaning. In the last part, thesis sums up the conclusion of the entire article.
