摘　　要：为了加强纸质文物的保护,对书画装裱材料宣纸的湿形稳性变化规律进行了研究。通过对不同条件下干燥方法对宣纸形变影响的研究,对纸张变形的原因进行了探讨。实验结果表明,宣纸具有随湿度变形的特性,变形程度与纸的纤维组成和干燥方法有关。采用梯度干燥的方式纸张的尺寸稳定性没有明显的改善。厚度和收缩率相关分析说明二者不存在相关性。随着纸张干湿交替处理次数的增多,其变形性趋于减小。为提高纸张的形稳性,可预先进行处理。The traditional materials used as a secondary support for mounting Chinese paintings were Xuan paper. In order to achieve a uniform mounting, the backing papers should have minimal expansion and shrinkage potential. The regularity of dimensional change of Xuan paper was studied, and the reasons of dimensional unstability were discussed. The results showed that the paper had the characteristics of dimensional unstability and the extent of deformation was related to the component and drying methods of paper. The dimensional stability of paper couldn't be improved by gradual drying method. With the circling times of drying and wetting increasing, the extent of deformation gradually reduced. To diminish the deformation of paper, some pretreating could be done.
