从八思巴字文献材料看《蒙古字韵》的成书时间

The Deduction of the Time When Menggu Ziyun(蒙古字韵) Be Written from the Documents in hP'ags-pa(八思巴) Script

1280年之后的八思巴字蒙古语文献中汉语词的拼写与《蒙古字韵》比较一致,前此的则与之表现出较大的差异;而1275年的八思巴字汉语文献则已经与《蒙古字韵》非常一致。据此可以推断,《蒙古字韵》1275年已经写定,而直到1280年其大力推行才比较彻底。

The spellings of Chinese words in the documents of Mongolian hP＇ags-pa（八思巴） script after 1280 are identical with that of Menggu Ziyun（蒙古字韵）, before 1280 are not. But the Chinese documents in hP＇ags-pa（八思巴） script of 1275 had already been identical with Menggu Ziyun（蒙古字韵）. So we can deduce that Menggu Ziyun（蒙古字韵） had already been written in 1275, but until 1280 it had been pursued vigorously.
