《中原音韵》中两韵并收字的读音性质；一直是北音学界探讨的难点问题之一，本文作者在将蒙元大都曲家所有杂剧（包括残剧）的用的作了穷尽式的研究之后，钩稽出其中的两韵并收字作独立的考察，并进行了多项统计。论文在更为科学的方法论基础上补充和修正了前人的结论，如文中证实东庚组并收字确实是很少兼押入两韵的，但否定了该组并收字是以叶入庚青为常的看法等。大都杂剧的用韵在元代最具代表性，更能反映《中原音韵》音系，因此摆脱就《中原》本身而研究《中原》的研究模式，而改从大都剧韵的角度探讨《中原》两韵并收字，由此得出的结论将是很有意义的。论文并且特别指出，并收字研究必须充分考虑曲韵宽窄等因素的潜在影响。 The nature of phonetic transcription of two rhyme and collected words in Zhongyuan rhyme has always been one of the most difficult problems to be explored in the North sound field. The author of this article exhausted all the dramas (including the dramas) After the study, Hutchison out of which two rhyme and received word for independent inspection, and carried out a number of statistics. Based on a more scientific methodology, the thesis complements and corrects the conclusions of the predecessors. For instance, it is confirmed in the paper that the collection of DongGeng Group is indeed rarely incorporated into the two rhymes. However, Green for the usual view. Most verses use the rhyme in the Yuan Dynasty is the most representative, more able to reflect the “Central Plains rhyme” phonology, so get rid of “Central Plains” itself and the study of “Central Plains” research mode, but from the perspective of most dramas rhyme of the “Central Plains ”Two rhymes and received word, the conclusion drawn therefrom will be very significant. In particular, the essay also points out that the study of word collection must take full account of the potential impact of such factors as the width and width of the rhyme.
