根据对以《礼部韵略》进行增修的两部韵书、以《礼部韵略》为基础加以编排的两部辞书和目前能见到的最早《礼部韵略》的版本——日本真福寺藏本的麻韵各小韵的排列次第的考察,可以看出:平声麻遮分韵始自《礼部韵略》(1037年)、上声马写、去声祃藉分韵始自毛晃增注、毛居正重增的《增修互注礼部韵略》(1162-1223年)。又根据麻遮分韵的发生地点,我们认为近代音初期的“中原”可能是以“汴京(开封)为中心的中原地区”。 According to the two rhyme books, the two rhyme books based on the “Rites of the Ministry of Rhyme” and the earliest version of “Rituals of the Rite”, which are two rhyme books, Ma Yun Yun Xiaoyun ranked second in the inspection, we can see: Ping Ma Ma sub-rhyme rhyme from the beginning of the “Propriety Ritual” (1037), wrote on the sound horse, Is the weight of the “increase the rebuke rhyme rhyme” (1162-1223). According to the location where Ma Fen is divided, we think the “Central Plains” in the early modern period may be the Central Plains region centered on Kaifeng (Kaifeng).
