探讨汉语语音史分期,最好只使用一种同质的语料。根据诗文用韵,可以将隋唐五代汉语韵部史分成隋初唐、盛中唐和晚唐五代三个时期。从隋初唐音系到盛中唐音系、晚唐五代音系,诗文韵部的发展趋势是逐渐简化,但韵部的合并限制在同摄之内,阳声韵部始终维持与入声韵部相配的格局。到五代时期才在入声韵中出现一些跨摄混押的现象。盛中唐是汉语语音急剧变化的时期,晚唐五代的诗文韵部系统基本上还是盛中唐的格局。所以,如果仅仅着眼于韵部系统的话,也可以将隋唐五代汉语语音史划分为隋—初唐和盛唐—五代两个时期。 To explore the staging of Chinese phonetics, it is best to use only one homogeneous corpus. According to the rhyming of poems, the history of Chinese rhyme divisions in the Sui, Tang and Five Dynasties can be divided into three periods: Sui Dynasty Tang Dynasty, Shengzhong Tang Dynasty and Late Tang Dynasty Five Dynasties. From the early Tang Dynasty Sui Dynasty tonal system to Shengzhong Tang phonology, Late Tang and Five Dynasties phonology, Poetry and Romance Department of the development trend is gradually simplified, but the rhyme of the merger is limited within the same photo, positive rhyme rhyme Department has maintained and into the rhyme Department of the pattern match. Until the Five Dynasties period, some cross-photographing and confrontation appeared in the rhyme. Sheng and Tang dynasties are periods of drastic change in Chinese speech. The system of poetry and rhyme in the late Tang and Five Dynasties is basically the pattern of Shengzhong Tang. Therefore, if we only focus on the rhyme system, we can also divide the history of Chinese phonetics of the Sui, Tang and Five Dynasties into two periods: the Sui Dynasty, the early Tang Dynasty and the Tang Dynasty - the Five Dynasties.
