【摘要】：南京大报恩寺遗址出土的宋代阿育王塔是目前国内地宫出土的最大的阿育王塔,该塔的出土对研究我国佛文化的传承体制、发展历程等具有重大意义。为恢复严重干缩变形的阿育王塔檀香木胎的原有形貌,采用"活性碱"作为润胀复原剂,对干缩变形的木胎进行了复原试验。采用X射线衍射仪、环境扫描电镜对复原前后的木质组织结构进行了表征。结果表明:经活性碱处理后,檀香木试样的结晶度由处理前的45.5%下降到处理后的38.7%,塌陷的木材细胞腔结构得以重现,变形的木材孔道结构由近椭圆形变化为近圆形。在对一件干缩变形的阿育王塔相轮处理试验中,经复原处理后相轮的经向尺寸提高了1.33%、纬向尺寸提高了10.03%,复原后的相轮与收缩前出土时外观尺寸相近。
[Abstract]:The Song Dynasty Asoka Tower unearthed from the ruins of the Great newspaper Ensi in Nanjing is the largest one unearthed in China at present. The unearthed tower is of great significance to the study of the inheritance system and development process of the Buddha culture in our country. In order to recover the original morphology of Ayowangta sandalwood tire with severe dry shrinkage deformation, the "active alkali" was used as the swelling restoring agent to restore the dry shrinkage deformed wood tire. X-ray diffractometer and environmental scanning electron microscope were used to characterize the wood structure before and after restoration. The results showed that the crystallinity of sandalwood sample decreased from 45. 5% before treatment to 38. 7% after treatment, and the collapsed lumen structure of wood was reappeared after active alkali treatment, and the crystallinity of the sample decreased from 45. 5% before treatment to 38. 7% after treatment. The deformed pore structure of wood changed from near ellipse to near circle. In the treatment test of a dry and deformed Ashowang tower phase wheel, the meridional dimension of the phase wheel was increased by 1.33 and the weft dimension was increased by 10.03, and the apparent size of the reconstructed phase wheel was similar to that of the unearthed phase wheel before shrinkage.
