《经典释文》中的《春秋左氏音义》、《春秋公羊音义》和《春秋谷梁音义》所录的少量音切与《经典释文》所引《春秋三传》异文存在密切的关系。有些音切是用来辨异文的无效音切;有些音切不是为字头注音,而是为异文注音。 The minor syllables recorded in “The Sound and the Meaning of the Spring and Autumn Zhaoshi”, “The Sounds of the Spring and Autumn Ram” and “The Sounds of the Spring and Autumn Guiliang” in The Classic Interpretations are closely related to the foreign languages ​​in “The Spring and Autumn Period and the Three Cloths” . Some syllables are used to identify invalid syllables; some syllables are not for head phonetic, but for the foreign phonetic.
