一再版说明拙著《中古音论》(河南大学出版社2006年)出版近一年以来,其中所收的《1900—2006年上半年国内中古汉语语音论著目录》受到读者的欢迎和同行的重视,我陆续收到一些鼓励、肯定和好评的来信,也收到一些非常有益的改进建议。由于这个目录的编写周期达十八年之久,体例是逐渐完备的。1991年9月以前我所编的论文条目,有相当一部分没有注明页码,有些论文条目的出处还有待进一步核实,有些条目失收,需要增补。 Repetition shows my clumsy “Middle Ancient Sound Theory” (Henan University Press, 2006) Published nearly a year, which received the “1900-2006 first half of Chinese medieval Chinese phonetics directory” by the readers and counterparts attention, I have received some letters of encouragement, affirmation and praise, and I have received some very helpful suggestions for improvement. Since the preparation of this directory for eighteen years, the system is gradually complete. Before September 1991, there were a large number of essay entries that I did not include page numbers. Some essay entries have yet to be verified. Some entries have been lost and need to be supplemented.
