自宋代張有《復古編》以來，聯綿詞一直就是漢語史中受關注的研究主題，尤其是在性質上的探討。近來更多的研究指出，聯綿詞上下二音節之間有密切的合諧性。聯綿詞的音節之間既有求諧的質性，那麼，有無可能出現為了因應不同的歷史階段的音韻事實，而對組合成份有所更動的情形？尤其魏晉以來反切的流行，音節成份被進行了較細緻的切割，於是也使得人們在更容易掌握聯綿詞音節間的和諧性的情況下，進而依據實際音感改造切語。近來已有學者指出其間的可能性，並且這些研究觀點也提醒我們，可以藉著聯綿詞考察語音的實際表現，尤其是反切大量流行以後的歷史階段。本文以澤存堂本《大廣益會玉篇》當中五百多筆的聯綿詞做為考察材料，除了藉以驗證隨著時代的往後推延，聯綿詞音節之間的聲音關係愈受重視的說法之外，並且也嚐試以這些材料加以考察《玉篇》韻系中的細節問題。

Lian-Mian-word（聯綿詞）has been an important subject in the study of Mandarin Chinese since Chang Yu’s work（張有）in Sung Dynasty. Many scholars have already pointed out the tight connection between the syllables of Lian-Mian-word and their sounds. Moreover, the fact that the sound of Lian- Mian-word changed throughout the time is drawing some scholars’ attentions. Since Fanqie（反切）was popularly used in the analysis of the sound by the literati in Wei（魏）and Ch’in（晉）dynasties, the ingredients of syllables of Lian-Mian-word is affected to have to make changed so that it could go along with the change of the sound. Two aspects will be discussed in this paper: I will, first, explain the phenomenon that the harmonious characteristics among Lian-Mian-word’s syllables would become more and more important to their development over the time by examining more than 00 Lian-Mian-words, which are selected from Ze- Cun Tang’s U-Pian（澤存堂大廣益會玉篇）. Then, I will discuss the rhyme system of U-Pian（玉篇） on the basis of my examination of Lian-Mian-word.
