目的 挖掘汉代铜镜纹样文化性内涵及中国传统纹样再设计价值，并将之创新应用于现代产品包装设计中。方法 首先，分析汉代铜镜纹样的社会属性和艺术属性，运用可拓语义分析的设计方法，提取纹样意向词汇并建构可拓表征模型，获得铜镜纹样文化语义设计区间;其次，辅助图解思维，将词汇语义转换为图解语义，进行语义表达分析和量值获取;最后，形状文法代入图解获得新纹样，与铜镜单元纹样结合生成有辨识度和设计价值的新纹样因子，并展开新纹样因子在产品包装上的设计实践。结论 可拓学相关理论可以将隐性知识转化为可显性表示和理性评价的文化基元，该方法为汉代铜镜纹样文化性内涵的内挖与外显提供可行路径，为中国传统纹样在现代产品包装设计领域中的再现提供一种延续性方法。

The work aims to explore the cultural connotation of bronze mirror patterns of the Han Dynasty and the redesign value of Chinese traditional patterns, and apply the patterns to modern product packaging design in an innovative way. Firstly, the social and artistic attributes of the bronze mirror patterns of the Han Dynasty were analyzed and the design method of extended semantic analysis was used to extract the intended vocabulary of patterns and construct an extension representation model to obtain the cultural semantic design interval of the bronze mirror patterns. Secondly, combined with the graphic thinking, the lexical semantics were converted into graphic semantics to carry out semantic expression analysis and quantitative value acquisition. Finally, the shape grammar was integrated with diagrams to obtain new patterns. Combined with bronze mirror unit pattern, a new pattern factor with recognition and design value was generated, and the design practice of new pattern factor was developed on product packaging. The extension theory can transform the tacit knowledge into the cultural primitive that can be expressed and evaluated rationally, and provide a feasible path for the inner and outer cultural connotation of the bronze mirror pattern of the Han Dynasty, and provide a continuity method for the representation of traditional Chinese pattern in the field of modern product packaging design.
