“敦煌学”即“敦煌吐鲁番学”,是一门综合性学科,也是一门国际性学科。因此不论是研究文史的还是研究科技的,也不论是中国的还是外国的,都可以进入这块宝地。我们杭大就有许多研究者进入了这块宝地,而且前辈已在这块宝地上开拓了一条道路。这条道路就是“敦煌语言文字学”——具体地说,这门学科包括文字、音韵、训诂等专门学科。例如姜亮夫先生的《敦煌瀛涯韵辑》就是一部音韵学著作;该书最后一卷《俗字谱》,又是文字学著作。又如蒋礼鸿先生的《敦煌变文字义通释》,旁引博辨,考释了一大批敦煌变文中出现的字和词,就同时是文字学和训诂学著作。再如郭在贻先生的《训诂丛稿》、《训诂学》以及一批单篇论文,使大多是考释俗字、俗语词的,有不少是属敦煌学的。这三位先生的著述代表了 “Dunhuang Studies” or “Dunhuang Turpan Studies” is a comprehensive discipline, but also an international discipline.
