《中原音韻》是元代周德清所著，完成於泰定甲子(西元一三二四)中。《中原音韻》的內容主要分兩個部分；前半部份是提供北曲創作的韻譜，以東鍾始，以廉纖終，凡十九韻部；每個韻部有陰平、陽平、上聲、聲四個部分，而入聲則是派入三聲；後半部份則是正語作詞起候包括字音的辨別、用字的方法、宮調和曲牌…等。日在韻部簡化成十九個韻部，變更了自切韻系統來韻書的體例，後代的劇曲創作，也都以此書作為準繩，因此無論從聲韻或戲曲的角度來看，此書都具有極高的研究價值。也因此，「版本」的研究，就不可不謂重要，除了可以幫助我們盡量尋求此書曘真實的原貌之外，對於各「版本」之間流變的情形也較能掌握，故本文就先以《中原音韻》目前可見的各種版本，稍加比對，以作為將來研究的基石。

“Central Plains Phonology” was composed by Zhou de quin in tai ding jia zi (1324A.D.) in the Yuan dynasty. It contains two major parts. The fore-body is about the rhyming of composing Bei qu. There are totally 19 rhymes. The rhymes aobut form deng zhueng yun and end up with lain xiam yun. Every rhyme contains four sections—in ping, iang ping, shang shen, qu sheng and ri shen is put into the three tones-ping, shang and sheng. The meta-body is “Zheng yu zou ci qi li” disouesing about phone discrimination, method of using characters, kueng dian, qu pai, and etc. “central Plains Phonology” reduces rhymes to 19 ones and changes the layout of rhyme books in qie yun system. Later, it becomes a rhyme canon of composing xi qu. No matter in the aspect of shen yun or in the aspect of xj qu, the look rewarded high value. Due to this the study of the edition of “Central Plains Phonology” is quite important. Through the study of the edition of “Central Plains Phonology”, we could get the original appearance of “Central Plains Phonology”, we could get now in my article. I hope that my studying result could become the foundation of the coming research.
