High-quality Mongolian to Chinese machine translation is of great significance to the development of IT in minority areas .To deal with the word alignment ,which is a key issue in SMT ,this paper proposes a Mongolian seg-mentation based on stems and affixes .To achieve this kind of basic unit of Mongolian Chinese word alignment ,we use stems and affixes table and reverse maximum matching algorithm .The experiment results indicate that the pro-posed method can significantly improve the alignment quality .
