《经典释文》陆氏反切唇音声母考

On the labial initials of LU Deming's fanqie system in Jindian Shiwen

本文运用统计法,对《经典释文》一书的唇音反切做了穷尽式的统计。从统计结果看,《经典释文》陆氏唇音的帮、非组反切中,音和切占了95%以上,类隔切不到5%;明、微组反切中,音和切与类隔切比例相当。通过与书中所录徐刘诸氏唇音以及陆氏又音等的对比,本文认为轻唇音非、敷、奉三母在陆氏唇音中已经出现,明、微母则尚未分化。陆氏帮、非组唇音的类隔切在当时存在着异读现象。

An exhaustive statistical survey of the labial initials in fanqie in Jingdian Shiwen shows that in LU Deming's labial initial system 95% of the fanqie of bang(帮) and fei(非) groups are harmonious fanqie (音和切) whereas only 5% are fanqie with inherited sound change(类隔切); in the ming (明) and wei(微) groups,the two fanqie types are almost a fifty-fifty split.With a comparison of the pronunciation of labial initials in Lu's system with his Another Pronunciation and also with other phonetic systems such as Xu's and Liu's in the same book,the paper concludes that the three labiodental initials of fei,fu(敷),feng (奉) have been differentiated in Lu's system,but not ming and wei.Furthermore,fanqie with inherited sound change of the bang and fei groups in Lu's system had variant pronunciations back then.
