钱大昕佚文及“地”字古音考

A Lost Article of Qian Da-xin and Rhyme Category of "De"(地)

国家图书馆文津阁所存臧庸《拜经堂集》中收录清朝乾嘉时代经学大师钱大昕的一则书信,未见于目前已出版的钱大昕的各种文集中。书信篇幅虽短,但其中涉及到很多有价值的内容,包括钱大昕与臧庸等人的交游过程以及钱大昕关于"地"字上古音归部问题的观点等等。其中,钱氏关于"地"字古音归部问题的看法集中体现了他考求上古韵部的原则和方法,值得后人借鉴。

A letter written by Qian Da-xin, a master of Confucian classic in Qing Dynasty, is included in the Baijingtangji by Zang Yong in the National Library, but not appears in other published works of Qian Da-xin. This letter involves the Contact of Zang and Qian, and the Rhyme Category of ＂De＂ （地） in Ancient Chinese Pronunciations. What＇s more, Qian＇s idea of Rhyme Category of ＂De＂（地） embodies the principle and methods of judging ancient Chinese pronunciations, which can be reused by scholars today.
