A Study Of The Different Words In Song

We have two methods to study the variation,one is judge the value of variation from the perspective of Philology,one is studing the system of variation from the perspective of Linguistics. We mainly make use of the latter one.The system of variation of Songshu(宋书) is relative with the studing of the variation.This paper collect the variation from the published work,the valueable version that no one uses,the Song Dynasty which the studier has not used,and research the problems from the perspective of Linguistics.The scope of collecting variation and the depth of studing variation gets more useful conclusions,there are innovation points below:First,reveal the variation from some important version,totall5000.Second,we fing the dates to check out the conclusions of predecessor,about20.Third,we discuss the questions need to be modified,about17.Fourth,we reveal and study the variation which no one has found,about7.Fiveth,we reveal the valuable,questionable variation,about4.By doing this job,there are three meanings that:First,do some job for the History of Chinese(汉语史) relating the variation.The research of variation is essentially judging the text.If we lack of research of variation,the study of History of Chinese would be get the wrong conclusions,Second,this research promotes the revision of Songshu.Third,there are some meaningsfor the synthetic study between Philology and ancient Chinese,concluding the collation of ancient books and Compilation of dictionary.
