【摘要】：石窟壁画是十分珍贵的文化遗产,但是其保存一直受到可溶盐及相关病害的威胁。研究石窟壁画可溶盐破坏过程是治理和预防这类病害的基础工作,深入的基础研究既需要全面的现场勘测,也需要实验室的模拟研究,能否制作出反映实际情况的试验样品仍然是十分艰巨的挑战。为此,作为一系列应用基础研究的第一步,通过对敦煌莫高窟壁画典型制作工艺和病害情况的调研,在敦煌研究院工作的基础上,规范地制作出便于实验室研究的模拟样品。通过对样品的破坏循环实验表明,所做样品可以重现可溶盐的迁移过程、分布状况和破坏情形。同时,样品的各种性能变化参数能够比较方便准确地测定,呈现的病害状况基本符合文物现场的实际现象,初步实现了石窟壁画病害的实验室模拟研究。本工作建立的模拟方法为深入开展壁画保护的基础科学研究开辟了一种途径。
[Abstract]:Cave murals are a precious cultural heritage, but their preservation has been threatened by soluble salt and related diseases. To study the process of dissolving salt destruction of grottoes murals is the basic work to control and prevent this kind of disease. The deep basic research needs not only comprehensive field survey, but also laboratory simulation research. The ability to produce test samples that reflect the actual situation remains a formidable challenge. Therefore, as the first step of a series of applied basic research, through the investigation of the typical production technology and disease situation of Dunhuang Mogao Grottoes murals, and on the basis of the work of Dunhuang Research Institute, a simulation sample which is convenient for laboratory research is made. The experimental results show that the sample can reproduce the migration process, distribution and destruction of soluble salt. At the same time, the variation parameters of the samples' properties can be measured conveniently and accurately, and the disease conditions presented are basically in line with the actual phenomena in the site of cultural relics. The laboratory simulation study of the mural diseases in the grottoes has been preliminarily realized. The simulation method established in this work opens up a way for further research on the basic science of mural protection.
