为了研究唐慕壁画白灰层的特性，本研究以乾陵等7座陕西唐墓壁画的白灰层为研究对象，使川超景深显微镜、扫描电子显微镜、x射线衍射仪、热分析仪和万能材料试验机测试了样品的显微结构、物相、尤机物干¨有机物含疆以及力学强度，并探讨了影响白灰层疏松程度、强度的因素。实验结果表明白灰层主要由无机物组成，包括碳酸钙、：氧化硅和锰白云石，平均含量88．71％，有机物平均含量9．33％。白灰层厚度一般为3-5mm，平均孔径约1．77μm，总孔数大致为7920个／mm2，平均抗折强度约0．96MPa。无机物与有机物含趟比与疏松程度早反相关性；疏松程度与强度基本上呈反相关性。小孔径、低含水率、锰白云石可能会增大白灰层的强度，该工作深化r唐荩啭㈣t＇l灰层的研究，为后期寻找更合适的渗透加同材料、工艺奠定了科学基础。

In order to study the characteristics of the lime layers in Tang tomb murals, seven Tang tomb lime layer samples, including one from Qianling, were analyzed with ultra- depth field microscopy, scanning electron micros- copy, X- ray diffraction, thermal analyzer and strength tester to determine their macroscopic and microscopic struc- tures, chemical makeup and mechanical strength. Results show that the lime layers are mainly composed of inor- ganic substances such as calcium carbonate, silica and magnesium dolomite. The average content of inorganic and organic substances is 88.7% and 9.3% respectively. The thickness is between 3 mm and 5 mm and the average pore diameter is about 1.77 I~m with roughly 7920 holes per mm2 ; The breaking strength is around 0.96 MPa. Furthermore, the ratio of inorganic to organic substances was in inversely correlated to its porosity. A small diame- ter, low moisture content and the presence of magnesium dolomite seem to contribute to an increase in strength. This study not only extends the research on the characteristics of Tang tomb mural lime layers, but also provides a scientific basis for the search for more suitable infiltration and strengthening materials and for technologies that can be used in later restoration efforts.
