碑刻文字作为出土文献的一种，是研究古代语言文字、历史文化的重要资料。俗字是正字系统的补充和后备力量。承接汉魏六朝之势，北周及隋代俗字依然繁芜，是汉字史研究的宝贵材料。正因文字俗体纷杂，造型奇异，导致这一时期的碑志释读困难，已有碑志整理成果常常存在误释俗字的现象。文章择取其中十二则俗字进行疏证，以此校正已有释读错误，亦为近代汉字及汉字史研究提供参考。

As a type of unearthed documents, inscriptions are important materials for the study of ancient languages, history, and culture. Characters of popular forms are the supplement and reserve force of the orthographic system. Following the trend of the Han, Wei and Six Dynasties, the characters of popular forms in the Northern Zhou and Sui dynasties are still complex, which is a valuable material for the study of Chinese character history. It is the variety of styles and strange shapes that make it difficult to interpret the stele inscriptions during this period, and the collections of the inscriptions often misinterpret the characters of popular forms. This paper selects twelve characters of popular forms among them and corrects with evidence their faulty interpretation, providing reference for the study of modern Chinese characters and the history of Chinese characters.
