摘　　要：汉代博局镜是具有皇权象征的一种国家礼器,搞清楚博局镜的设计原理与数学结构,或可以提供一种有效的鉴定博局镜真伪的标准。运用数理考古的方法,通过对现代出土的几乎所有博局镜之核心结构的设计蓝图的复原和分析,确认TLV符号完整的汉代博局镜,均蕴含三圆三方的结构;同时证明,TLV符号不完整的汉代博局镜,基本上不存在三圆三方的结构。这一结果提供了鉴别博局镜真伪、区分博局镜究竟是皇室礼器抑或民间用品的一种标准。The Bo Ju mirrors of the Han Dynasty were national ceremonial vessels that symbolize imperial authority.Understanding the design principles and mathematical structure of the these mirrors can provide an effective criterion for authenticating their genuineness.Using the method of mathematical archaeology,and through restoration and analysis of the design blueprints of the core structures of almost all recently unearthed Bo Ju mirrors,it is confirmed that Han Dynastry Bo Ju mirrors with complete TLV patterns contain a structure of three circles and three squares.At the same time,it has been proven that the incomplete TLV Bo Ju mirrors do not contain a three-circle and three-square structure.This result provides a standard for distinguishing the authenticity of Bo Ku Mirrors and distinguishing whether they are royal ceremonial vessels or civilian items.
