二〇〇九年初，北京大学受赠获得一批从海外回归的西汉竹简。从内容上看，这批汉简全部属于古代书籍，不见文书类文献，因而称之为“西汉竹书”。竹书含有近二十种古代文献，其中包括《赵正书》。北京大学藏西汉竹书《赵正书》是一部已亡佚的汉代文献。本文将通过笔画、结构、章法和风格等四个方面来对北京大学藏西汉竹书《赵正书》的书体特征进行分析。

At the beginning of 2009, Peking University received a batch of bamboo slips of the Western Han Dynasty returned from overseas. In terms of content, these Han bamboo slips belong to ancient books, and there are no documents, so they are called "bamboo books of the Western Han Dynasty". Bamboo calligraphy contains nearly 20 kinds of ancient documents, including Zhao Zhengshu. Zhao Zhengshu, a bamboo book of the Western Han Dynasty collected by Peking University, is a lost document of the Han Dynasty. This paper will analyze the stylistic characteristics of Zhao Zhengshu, a bamboo book of the Western Han Dynasty collected by Peking University, from four aspects: stroke, structure, composition and style.
