九连墩战国编钟形声复原研究

Recovery both the morphological and acoustic characteristics of JIU-LIAN-DUN chimes in the warring states period

文物界修复编钟残件的传统方法是对编钟先矫形后胶接或钎焊,使用这种方法可以做到"形似",但无法获得良好的声音。为同时能获得良好的声音,通过对矫形定位、焊接方法、焊接材料、修复声弓等修复环节进行研究,采用激光焊接技术修复九连墩出土的破损双音编钟。修复结果表明,不仅复原了编钟的外观尺寸和形貌特征,而且在音频、音品方面恢复了双音编钟的乐钟特征,实现了破损双音编钟的形、声复原。研究成果可为古代金属乐器的形、声复原提供了一套全新的技术路线和工艺流程。

The coventional conservation procedure for broken chimes is adhesive bonding or Stannum brazing after the orthopedic procedures. This method can recovery the shape of chimes, but can not recovery their acoustics characteristics. This paper introduced the method of laser welding used in conservation of the broken chimes. By the detailed study of orthopedic procedures, welding process and filler materials, etc. , the broken chimes unearthed from JIU- LIAN- DUN Chu tombs in the warring states period are well recovered both in morphological and acoustic characteristics. This conservation method is innovative for the recovery of morphological and acoustic characteristics of antique metallic musical instrument.
