Phonology Research On The Theory And System Of Episodic Phonology

"Phonology Occurrence" is a widely spread collection of phonology at that time,the author Guo Shigu combined his dialect to judge the right and wrong of the ancient sound problem,changed 36 letters to 30 letters,arranged the letter cut character map,the picture reflects some phonological characteristics and modern Yongxin dialect is basically the same.This paper mainly studies the phonological duality from the following four aspects.First,the analysis of the version of "Phonological Occurrence ",it is concluded that there are three versions seen today,namely Tongzhi twelve years of living characters,Tongzhi twelve years of engraving,Guang Xu twelve years of engraving.The following is to compare the phonological contents of Tongzhi Ben and Guang Xu Ben,which include "four-tone theory "," anti-theory "," sound rheology theory ","letter theory ".Through comparison,it is found that Guang Xu Ben is actually a reduction of the same root,and the content of the same root is more complete and systematic.Second,the problems of phonology theory in "phonology occasional existence" are dredged,mainly by combing "four-tone theory "," anti-shear theory "," sound rheology theory "," letter theory "," entering sound non-ancient theory" and "entering sound theory ".It is concluded that the four-tone should be yin-ping,up sound,go-sound,yang-ping;entering sound into yang-ping;and the consonant should be 30 consonants.Thirdly,the consonant system,the rhyme system and the tone system are obtained through the study of the rhyme map and the letter cutting diagram attached to the same treatment.Then the phonological features of Tongzhi’s Phonology and Guang Xu’s Phonology are compared,which is mainly to analyze the correspondence between rhyme parts.Fourth,the phonetic features reflected in the Alphabet Chart are compared with those reflected in the Yongxin Dialect Research,and the rules of phonetic evolution are obtained.
