青铜文物研究中CT成像的几个作用

Several functions of CT imaging in the study of bronze artifacts

通过计算机断层扫描(CT)检测与成像分析后发现:陈璋圆壶的组成构件有26个,而非最初考古报告表述的19个,分三个部分合成;吴王僚剑的剑体腐蚀严重,剑上铭文为铸造而并非后刻;春秋青铜盘修复前的状态清晰可见。由此说明,CT技术在研究古代青铜器铸造工艺、鉴定青铜器真伪、检验保护修复技术路线等三个方面能起到关键作用。

Through the detection and imaging using computed tomography(CT),it is found that 1)there are 26 components of the Chen Zhang round pot,instead of the 19 described in the original archaeological report;2)the body of the sword of Liao(king of Wu)has been seriously corroded and the inscription on the sword was cast rather than engraved afterwards;3)the state of a bronze plate of the Spring and Autumn Period before its restoration is clearly visible.It can be seen that the CT technology can play a key role in revealing the casting process of ancient bronzes,identifying the authenticity of bronzes,and inspecting the technological routes of conservation and restoration.
