中文摘要：

以生物学的相关知识为背景，在国内外对DNA计算与DNA计算机研究的基础上。利用DNA分子链具有的Watson-Crick互补结构和其巨大的并行性这两大生物特征所呈现的数学特征，在经典自动机的基础上定义了DNA自动机、DNA正则语言及DNA正则文法，并证明DNA正则语言与DNA正则文法的对应关系．

英文摘要：

On the background of biological knowledge, based on the research of DNA computing and DNA computer at domestic and overseas, we define DNA automation based on the classic automation made use of Watson-Crick complementary structure and the parallelism of DNA molecular. At the same time, we propose DNA regular languages and DNA regular grammars. Finally, we discuss the corresponding relation of DNA regular languages and DNA regular grammars.
