中國古代字書訓釋具有傳承性，源頭性字書對後代字書訓釋有深遠影響。《廣雅》是魏晉時代產生的一部具有代表性的源頭性字書，研究《廣雅》訓釋需由訓釋語境還原入手。本文以《廣雅》訓釋為研究對象，考察探求《廣雅》訓釋的訓釋來源，還原相關訓釋產生的文本語境，總結《廣雅》生成改造訓釋的具體方式。在還原訓釋來源的基礎上，進一步還原張揖編撰《廣雅》的工作步驟、操作原則及改造細節，歸納《廣雅》的編纂體例和訓釋義例，最後對張揖編撰《廣雅》的整體工作做出評述。論文共分為五章：

第一章，宏觀概說《廣雅》成書淵源。以縱橫雙線展開，橫向在張揖個人整體經學-小學學術成就中找尋其“雅學”位置；縱向以張揖《上<廣雅>表》作為切入點，歸納張揖以“古訓是式”的崇古觀念、“近正辨言”的功用觀念和“文約義固”的擇訓觀念等作為《廣雅》纂集訓釋時的指導理念。

第二章，介紹探求《廣雅》訓釋來源的具體方法。考察《廣雅》訓釋來源的基本方法，是進行訓釋對比，訓釋來源的對比單位可分為訓項、訓釋、訓列三級。根據訓釋對比結果，得到一般來源文獻書目，再以“訓條關聯互證法”增強訓釋來源判斷的證據力和可信度，整理得出主要訓釋來源文獻書目。訓釋對比過程中，會遇到用字差異、直接來源和間接來源、單一來源和多向來源、訓釋來源和源出語境等影響因素和相關現象。

第三章，歸納描寫《廣雅》吸收訓釋方式。《廣雅》中所收訓釋究其來源，有承自故訓和自主創制兩支。承自故訓分為原訓繼承和改造吸收兩類，改造吸收又分為易字式、省齊式、置換式、截取式、遞進式、熔裁式六種具體處理方式。由此歸納出《廣雅》吸收改造訓釋的基本條例，即張揖工作編纂過程的操作原則。

第四章，在推求訓源的基礎上，仿照前代雅學著作釋例研究範式，總結《廣雅》的編纂體例、訓釋義例和用字特點。編纂體例，分為纂篇、連訓、屬辭三個層級，從特殊訓釋（如聲訓、雙音詞訓釋）纂集和訓辭次序依據，看《廣雅》對《爾雅》體例的發展和完善。訓釋義例，從訓釋來源的角度重點探求“奇偶相釋”例、“二義同條”例、“連言為訓”例、“一物二名用謂之”例、“名物別”例等五例。

第五章，對張揖編撰《廣雅》的工作過程及成果進行學史地位評述。根據對張揖處理故訓材料過程和方式、原則和標準的整理還原，從張揖學術自覺、《廣雅》訓釋原創性、雅書類聚範式性三方面，肯定《廣雅》在雅學發展過程中的完善之功及其啟示意義。

The explanations in ancient Chinese wordbooks are inheritable. Source wordbooks have a far-reaching influence on the wordbook explanations in future generations. Guangya is a representative source wordbook produced in the Wei and Jin dynasties. The study of Guangya explanations needs to be started from the restoration of the explanation context. This paper takes Guangya explanations as the research object, investigates and explores the sources of Guangya explanations, restores the textual context of relevant explanations, and summarizes the specific ways of formation and transformation of Guangya explanations. Based on the restoration of the explanation sources, this paper will further restore Zhang Yi’s working process, operational strategies, and transformation details when compiling Guangya, and summarize the compiling format and explanation evidences in Guangya, and finally give comments on Zhang Yi's overall work in compiling Guangya. This paper is divided into five chapters:

Chapter One is a macroscopic overview of the origin of Guangya. This chapter makes vertical and horizontal discussions. Horizontally, it seeks for its Yaxue position in Zhang Yi’s academic achievements in his overall study of Confucian classics-Philology (writing, annotation, and exegesis on antient Chinese language). Vertically, taking Zhang Yi’s Shang Guangya Biao as a starting point, it summarizes his antient worship concept of “Following the ancient explanations of previous generations”, the functional concept of “Meeting the ancient standard language”, and the explanation selection concept of “Concise and comprehensive”, etc. as the guiding concepts of compiling Guangya explanations.

Chapter Two introduces specific methods for exploring the sources of Guangya explanations. The basic method for investigating the sources is to make comparisons among explanations, which can be divided into three levels of xunxiang、explanations, and xunlie。According to the comparison result, the bibliography of general sources will be obtained. Their evidential value and credibility will be strengthened through xuntiao correlating cross-proof method, and the bibliography of main explanation sources will be sort out. In the process of comparing the explanations, there will be influencing factors such as differences in characters, direct sources, secondary sources, single sources and multiple sources, etc. and related phenomena such as explanation sources and their context, explanation sources and word sources, etc.

Chapter Three summarizes the way in which Guangya absorbs explanations. The sources of the explanations recorded in Guangya are inherited from ancient explanations or created independently. The inheritance of ancient explanations is divided into two categories: heritage of the original explanations and absorption of transformed explanations, the latter can also be divided into six specific processing methods: change of words, omission, replacement, interception, progressive type, and extraction of common ground. The basic principle of the absorption and transformation of Guangya explanations, which is Zhang Yi’s operating strategy in his compiling process are carried out in this way.

Chapter Four summarizes the compilation style, explanatory laws of explanations and word characteristics in Guangya based on the investigation of explanation sources, following the research paradigm of explanation examples in Yaxue works in the previous generations. Compilation style can be divided into three levels: article, series and word, especially viewed from the development and perfection role of Guangya on Erya’s style on the basis of special explanation compilations and the order of words. Explanatory laws of explanations mainly explore five relevant principles and laws from the point of view of explanation sources.

Chapter Five makes academic and historical comments on Zhang Yi’s working process and academic achievements in compiling Guangya. By sorting out and restoring Zhang Yi’s working process and methods, principles and standards in dealing with ancient explanation materials, from three aspects of Zhang Yi’s academic consciousness, the originality of Guangya explanations, and paradigm of Yashu, this chapter fills more details in the perfecting role of Guangya in the developing process of Yaxue.
